I love UMA projects. The way you go about things - using as much of a commercial product as possible and then adapting it - is exactly how I go about my own projects. It's really great that you're ahead of the game with this sort of thing. Hopefully someone in the right industry will come along and work with you to develop something.
I'd imagine if some kind of flexible carbon tube long enough would be better (and possible in terms of cost) for energy transfer (because it should be stiffer against torsion)
@@BrunoVasco definitely, it would just be about storing it and dealing with it if they really do intend to make it removable especially. I was thinking potentially some type of telescoping aluminium pole. Something similar to a paint roller extension. Could also make something out of small tube and use some type of pins or couplers to put it together for use.
With the torsion line you could mount more blade(s). You can use a boost transformer to raise a constant voltage to a usable voltage going into your mppt controller . The initial generated power needs to be regulated somehow like a car alternator has a regulator to prevent over voltage.
Greetings from home (Canada). I've been enjoying your posts from day one and have to comment, yours is by far the most original, interesting and truly adventurous. 99.9% of every other sailing channels are showing and doing the exact same thing sail warm water only stay away from the rest of the planet. I didn't think it was possible but I'm sick of seeing the Caribbean, Mediterranean and Florida. But you have shown us a picture of Norway its waters and the North Atlantic no one else has. Illustrating that not all sailing is fair weather but it can actually be raining or snowing and using the sails is your first choice over motoring. Thanks for showing us a truly different part of the planet. You were leaders in all electric propulsion and again are leading with vertical wind generation, well done Uma.
Even Delos has done some Northern cold water stuff lol. It certainly isn't the norm, but it's becoming the new thing since like you said everyone has done all the warm water stuff.
@Susan Olsen. Norway has a lot of this type landscapes, looking especially exotic in winter clothing, and these guys are good at showing it. If you like it, you might also have a look at a small youtube channel called Alluring Arctic.
All this research you do and the reality you bring to the table should and probably is inspiring many innovations in Green methodology and prepper craft.
@@tonybarnes3858 funny how close they are together. Minimalism and sustainability is what our two living examples are sharing with us. Prepper craft as you are saying is a side affect. But it could be lucrative for them which becomes financial sustainment
You’re content just keeps getting better and better. You guys are wonderful storytellers. Also as someone who grew up dealing with old diesel and gas boat engines I love seeing you’re real life experiences going all electric
Dan, another thing that might have even more torsional rigidity and would stay straighter would be to use some high burst test hydraulic hose for your shaft. You might even be able to put the hose inside a PVC sleeve to make it even stiffer. Schedule 80 PVC electrical conduit has a pretty thick wall. If you got really sharp you could put seals at both ends of the shaft and then put a light oil in it to cut the friction. You should be able to find some hose about the size of the bore in your coupler. If not, you could use a piece of shafting installed in the coupler and then slide the hose over it. The rubber liner of the hose could be drilled out to get a very tight fit on the stub shaft. A good hydraulic fab shop should be able to use a crimp on fitting to attach the hose to the piece of shafting. You could then do something similar at the top. You might even be able to put more tension in the hose connector to keep it from whipping against the mast. I look forward to seeing what you come up with. Is there gearing in the turbine to spool up the RPM inside? In Sweden where I just bought a farm, have also found good quality crimp on studs that will cure your problem with the screw on terminal blocks. The smoke may have simply been the new boards burning off manufacturing residue.
One of the oddest and coollest things I have seen was walking across a beach in the Hebrides and leaving snow footprints. The beach had been covered in snow like you saw, then a storm threw sand over all the snow, hiding it until my feet broke through.
@sailinguma we are an electric sailboat in the PNW. We tried a big wind generator mounted on our mizzen mast first. It required a lot of wind to generate any usable electric over too long a period. And besides the issues you wisely mentioned, the drag was affecting our sailing, balance and steering. And those are moving parts requiring maintenance. We switched to solar only. No hydro. We haven’t plugged in since beginning of season.
Hahaha! YESSSS! You surprised us! I am so happy to see this episode! Based on our prior conversation I knew you were planning something but I didn't know you were planning to let us in on your plans so soon! I can't wait to see how this evolves. You two are sail boat pioneers! I love it! I also love the nod to More Sailing Less Bullshit Erik Aanderra! I love his channel!
Two awesome elements of this video: 1. Great poke of NBSJS 2. I have been thinking about a VAWT for my little boat as well so I'll be watching this project with great interest.
Never put soldered stranded wire into a screw-down terminal - the solder slowly flows under the pressure and you will end up with a bad connection in time. It's against electrical codes because of that. You can crimp the stranded wire into a ferrule, and put that into a screw terminal.
As a Union Electrician&live aboard for 25 years, told by an Arctic Sailor NOTHING you do stops corrosion; not shrinktube, liquid tape, solder, whatever, I prefer thick solid wire in a bent loop, but I'll take STRANDED, split&twist fibers, form them around a nail or post, twist the end again forming a tight loop, and crush between stainless washers for a "LUG TIGHT" connection that lasts, knowing in 2-5 years I'll probably have to redo it. As for aluminum connectors and soldered or crimp sockets I hate them; they all rot.
24:05 (The trapped air in the sand) The out going and incoming tide is the cause, as water drains out air will fill between the sand and because of the (water service tension rule) trap the air when the tide "floods" the shore line again. What also helps a lot is that there is no or very very little wave action to smash the air out...
To smooth delivery of a "choppy" power source, you may need to implement some kind of flywheel between the torsion line and the motor. With the moving gear, you may want to enclose it in a housing. Good luck!
I love watching their modification videos. I know little to nothing about sailing but I love watching this channel. These two are proof that anything is possible with the right mind set! Keep on living the dream!
An Erik photobomb would have been hilarious, but at least he posted. Great episode! Love the barefoot, toqued, campfire dinner. You two really know how to live!
As usual, that was interesting. Intriguing, really. I had no idea of the size of the vanes. Dan, you truly are a magician! You make Macguyver look like a school kid. It's so nice to hear Kika's laugh, see you two again. I get withdrawal symptoms between vlogs.
Amazing guys! You both are an inspiration for sure. Not surprisingly You are going to be remembered as the ones who changed the meaning of sailing. I'll not be surprised to see a Sail Boat line by the name of UMA with the very same logo to be out there very soon in compitition with other big names. Hats off to both of you, what a great team.
8:54 for a good reason, they are very inefficient. When wind blows through a normal "vertical" propeller, it hits all the blades at once and ALL blades transfer that force to spin it in the SAME direction. On a "vertical" propeller the wind pushes on all blades as well, BUT having a center axis means one blade wants to go in the one direction and the other two in the opposite. Yes they present a different shape when at the "wrong" side but still generate a lot of drag and Is this drag that reduces the efficiency up to 30% or more. If you need smaller and more powerful wind turbines, pick one with more blades and less diameter.
What about the Darius design? I would expect the blades to be generating lift 90% of the time. It also looks like a design that you could put on a mizzen mast, let spin when you are not sailing, and lock perpendicular to the boom when you are using the mizzen sail.
Love your RUclips posts. Notice there is often strong tidal currents where you go. Would be possible to anchor in the current ( or tie up to a channel marker) and use the flow to activate your regen equipment?
@@charonstyxferryman Actually it does. He's addressed this before. The regen requires about 4-5 knots of water over the prop, that's a really strong current.
Absolutely. DON'T solder the wire ends you intend to connect to the screw terminals. Solder is too soft and the connection will become mechanically loose and electrically unreliable over time. Yes, many people have done the soldering + screwing in the past but it's bad practise.
A simple trick to use in a pinch is to strip two or three times as much insulation to give you more exposed wire and simply fold it up to make it bigger to give a tighter fit.
I just finished going electric in my 31,000lb 1975 Hughes 40 Ketch, I'm absolutely loving it! Just sailed it for the first time. There are so many advantages and only one draw back. Thank you for the inspiration.
Exciting stuff, can't w8 to see what Dan is gonna conjure together on the wind generator. I hope it works out looks very interesting. Love the shot where Dan passes by with lumber and Kika is chugging behind with twice the lumber. Gr8 stuff.
Wonderful episode you guys ! Very cool. I remember as a teenager having to fetch firewood in the winter up in New Hampshire. Tried to get it to burn with old newspaper but it was just so damp . Living in Florida as an old man I don’t worry about that anymore. Have no idea how she can walk barefoot in that freezing water. I’d be complaining three days straight after that. Beautiful place you anchored at. So peaceful. You don’t have to sail to entertain us. This episode was that perfect example. Stay warm …
Here's a possible solution for the solid / stranded wire issue on the boat. Go to Amazon and look for these two items: 1. Hilitchi 800pcs 10-24 A.W.G Wire Copper Crimp Connector Insulated Cord Pin End Terminal Kit and 2. IWISS Self-adjusting Hexagonal Plier for AWG23-10 End-sleeves Ferrule. I use them and love them! you can crimp them onto stranded wires and have a solid tip to screw the connector to - with no soldering and no fuss! Love the channel, been watching for a really long time. Keep up the good work!
I adore this forward thinking. Electric sailing, no diesel, no pollution. I was wondering a few months ago how you could use wind on a sail boat to generate more power. I love what you came up with honestly. Brilliant. I had been thinking myself, how a Catamaran could use water between the hulls , to create more additional power while sailing. Using the same concept in rivers and stream with a small two foot water, paddle generator. Using the same concept, a small water paddle placed under the boat could create more power while sailing/moving through moving seas as you sail. There are more ideas out there as to how to generate enough power to live with, on a high level. I'm pretty sure you two will be leading this forward thinking technologies for future sailors and even bigger boats, ships, etc... Kika, Dan...Thank you.
Loved this DIY episode. Great scenery. Interesting that you left Canada to sail across the North Atlantic to enjoy a cold beach, snow on the mountains, and sit by a fire made of damp spring wood. ;)
Yeah, and then he uses British slang when he calls the terminals "rubbish" and not "proper," LOL. I speak Canadian, and have worked in England. Then we have Kiki's adorable Haitian accent. These two are so FUNNY, and smart, and put together a mishmash of amazing vlogs with absolutely beautiful cinematography. Very cool wind turbine prototype!
You guys are mavericks in your quest for green energy solutions. I salute you. You instill a sense of hope, that perhaps there are others like you, inquisitive minds leading us all into a bright future. Thank you
Lovely project! If you add a universal joint at the generator input, it will not be as sensitive to alignment between generator axis and the torsion line. In the scene 03:48 you have made a yoke coupling out of a tube, the slot is at 90° to the first bolt hole, try leaving that bolt, through the generator shaft, slack so that the coupling can rock a few degrees and that should do as a mock up. I agree with the comments about a thrust bearing, the tension on the torque line was possibly causing the generator bearings to bind, hence the squeak and slow running. The generator's bearings will probably designed for rotation only, with no provision for thrust. l love taking things and adapting them to suit a new purpose, good luck... hopefully you will create the Uma class generator, which we will soon see on every clever yacht.
Dan , inside your typical gas powered weed eater - lawn trimmers they have a flexble square metal cable that spins inside the tube running between the motor and the spinning head . It might give you less flex if you used the whole assembly.
Ahh yes, good point. You could potentially use two straight shaft variety trimmers and couple then together. Be cool if some old trimmers could be found at the dump or junkyard. This is similar concept ad speedometer cables from cars I believe. Idk if they would be stiff enough to transfer the load, but similar concept.
Just a few things to consider for the wind generator. The unit you have is way to big for what you are using for a wind rotor. Look at most pull behind aqua gens and you notice they use a small diameter generator section. That is because they cannot create a huge amount of torque to spin the gen . With a wind gen you have even less torque so the gen has to be small. You have to trade off torque for RPM. With a smaller gen it can rotate in less wind. With the torque line mount all you need is a straight coupler that mounts onto the gen shaft. Then you swivel the gen where it mounts to the deck to line up with the torque line. Also you want a gen that is at least 3 phase to even out the pulses from the gen spinning. No wind gen is going to delivery huge amounts of power at one time. But it does give power 24/7 as long as the wind is blowing. Just a thought, TP
I like this from the title, actually. It did not disappoint, as usual. There seems to be no reason to *not* have a series of those vertical axis blade sections linked and hoisted by a single jib halyard, like a sail, pinned to a generator on deck (or below) able to fully capture that torque. I am sure blades could be fashioned to compensate for the tilt if it's an issue. I wonder how easy it is to trim and curve some plastic sheet into blades and clamp them to that torsion rope... Nice.
Spectacular photography! Good to see that the wood stove is in use. Great creativity and teamwork. You may already have these ideas in your wind vane "options" list: #1. Use a metal/plastic tube/pipe rather than the flexible torsion line. In concept, this would be similar to the threaded drill pipe used for water/oil drilling. Use 1/2" or 3/8" tube, 4' in length threaded at each end. Easy to assemble and store. #2. The wind vane appears to be about 2' high and 3' in diameter. Consider stacking several wind vane segments to increase the torque.
I'm sure you will figure out a manageable way to use your wind generator. Il definitely give you props for being adventurous and trying new things. "Nothing ventured nothing gained". ⛵
I did a fair bit of work with wind generators at one time and I came to the conclusion there is no substitute for size. Small ones make more noise than power and although they seem ideal for sailing boats they really are just a novelty item that produce a token amount of charge. That 'motor' as you call it is the alternator, it needs to be spinning more than 1000 RPM to get a reasonable amount of power and as you know the wind is never constant. It also probably will not stand up to a lot of tension being put on the shaft, pulling on it like that will wear out the bearings very quickly. Also they need some type of brake fitted to stop them over revving in high winds, there are mechanical solutions and electrical. You can have a small paddle that is spring loaded which will operate a small hub brake or cable operated disc brake. Or you can set up an over volt detection system that returns power to the alternator which energises the field coils and pushes against the rotation to prevent it getting out of control. Both systems have their faults but you cannot run a wind generator safely without one. Large wind turbines are much more efficient because they have a lot of inertia and can be geared up to produce higher RPM's which produces higher voltage and higher power, small ones are only any good for lower voltages, less than 24V and low power.
But I have to say. This is one of the coolest DIY-things on sailing channels ever. Looking forward to see it working properly - and add one onto my plans as well!
I watched this in August, during a heat wave and wildfire smoke here, and never has the time lag of videos been more refreshing LOL The snow on the mountains, your winter clothing, was cooling to look at.
First of all let me say you guys are amazing my wife and I have been watching you since you started we're an older couple and bought a 38 ft Ericsson sailboat unfortunately we don't have the drive that you youngsters do but everything that you have done to your boat is simply amazing. Also everything that you've done to your boat is exactly what I had intended on doing to mine I have a wind vane ready to install just like yours I want to do electric motors just like yours I want to do battery Banks just like yours and I've been studying wind turbines and thought about doing twin vawts on the back at the radar Tower one of the things that I thought about and making a vawt was to do counter rotating blades so that slower wind speeds would create twice the energy instead of just one stator you would have two going in opposite directions because the blades would be going in opposite directions counter rotating squirrel cages so to speak just a thought.
Dan, I love boat work episodes, they aren't bullshit, keep em comin! As much fun as it is following where you're sailing, its fun to see the projects too to fantasize about what I'd do on my boat if I ever get one.
The squeak was from the fitting I made. Also, most sealed bearing can handle a small thrust load, if they’re installed properly. But that motor isn’t going to be staying long.
Brilliant Umaneering! I love how whenever you come across a problem that would seemingly involve something that doesn't exist you just go and invent it - no engine, use one from a forklift. No wind turbine or one too noisy - put up with it no.. invent one! Just wondering though - could you put more than one of those wind turbines above each other to improve the sail area - potentially generate more power in lower winds and shorten the tension wire (great idea by the way!). Have to mention the techical side of this video and the editing - I always love your videos, but this was great - starting with a beautiful sunny drone shot of Uma looking as if she was in the tropics before panning to show Norway, brining it all back to a caribean/norway barbaque at the end was brilliant, although poor Kika's feet! Great title too, lovely nod to Eric :-)!
Having a garbage truck of memories I can remember something that should be of assistance. About 6 month to a year ago I was surfing YT about hydroponics and came across this guy who was heavily into designing his own systems. He designed his own Wind generator like yours except fixed with a solid connection. The thing is he went from a prototype to something that produced approx 300 watts roughly 10 to 20 times his initial output. This was not by making it by making it bigger but his generator was a round horizontal disk rather like a plate and like plates he was able to stack the Stator's slightly offset on top of each other. Wish I could remember the video it was a brilliantly simple engineering solution and very compact, though of course this term is relative when you live on a 30 odd foot sail boat
Great video as always :) Love the NBJS Reference and message from EA! Vertical wind turbines... You are creating a brake and wear point by pulling on the spindle like that, consider a solid bar so there is no tension between the vanes and generator. That way you can focus on steadying the vanes top and bottom
Arent you putting a vertical load on the bearings of the generator/alternator? My guess would be that putting tension on the axle that way will wreck those bearings in no time.
How ironic, the most relevant topic you have ever covered to date. My passion for sailing is all about self sustainable green living. This is the kind of thing that got me to follow you two. Love it !!! Keep it up !!!
Some suggestions.... 1) Increase the length of each blade from 24" to 48" tall. 2) Decrease the curvature of the blades by using a larger diameter of PVC pipe. (These two changes mean the overall blade diameter would be smaller and could increase rotational speed) 3) Hard shaft a ten foot 6 - 8mm rod on a Universal Joint at each end with the top mounted to a sealed bearing. 4) Top bearing would be mounted to a hinged plate attached to the mast. The hinge allows for varying tension from a backstay. In theory this would allow the unit to remain in place in a permanent sealed and covered mount. Just a thought, Kirito in Providence
Love your connection to NBSJS. You guys and Erik are fantastic. Some ideas about wind charging: 1) Not sure why you went with a 3 phase gen but you need to be sure your MTTP or whatever controller you have takes 3 phase input since that needs to be converted to DC. 2) you need a firm connection to the gen. How about meter long thin wall tube/pipe tied together with couplers? 3) there's probably a threshold RPM for output on the gen and that;s usually somewhere roughly around 1000rpm. You need a reduction gear or at min a large wheel attached to the windmill shaft with perhaps a fan belt to the small wheel on the gen. 4) knowing the generator's need for rpm and wattage output, look for calcs. on the mechanical energy input needed. One way to see if all this works is to find the mechanical energy conversion based on wind speed for that wind mill. Let me know if you;re interested in that. Best wishes!! Dean
I would have considered a universal joint and a thrust bearing when connecting the torsion line to the motor/generator for smooth rotation. Love the BS.
Sausage on a stick over a fire on a beach in Norway isn't such a bad deal. Neither is hot chocolate and moonshine. Building another genius gadget is so Uma. God love you two!
First, I love that you guys try stuff and don't get dissuaded by the nay sayers. Keep at it. I completely agree that wind and solar are symbiotic energy harvest methods. As far as the turbine goes, the reason vertical axis suffers in efficiency is that it has to drag a vane against the wind for every vane the wind pushes. So each rotation looses some % potential net energy capture. Since the total energy gained over time is an integral of the energy per revolution and the rotation speed, the small efficiency loss is magnified. Anyway, I totally get the mounting challenges of combined wind and solar. No easy answers to hard questions.
@@SailingUma it shouldn't be that hard to have the same system and avoid placing so much axial load on the bearings, you could have a bracket soldered to the motor chasis for tension and a rigid thin "core" to transfer the rotation, something as light as possible like a pvc pipe, so that the whole system can be disassembled when storms happen but it's easy enough to mount again the next day
I think this is a really great alternative idea. I may go with a more rigid carbon fiber tube as the "drive shaft" eliminating rope flex and tension. It could be stowed below just like a long fishing pole. Looking forward to more experiments from Uma 👌👍
Step 273 sold me on subscribing!! I just discovered Sailing Uma yesterday and binge-watched last night for hours. But the scene deep in Norway with a need to recharge was a great lure for me. I want more!!! Renee G P at the South Sound of Washington
I agree , you need more tension because allot of energy is going into moving the wind vanes laterally, but your generator bearings may not handle that much thrust
This has got real potential but I second that observation. The bearings will be able to take a bit of thrust but nothing like the load you have put on. A broom handle connection would keep it all in line without high tension, but then of course you will need a bearing higher up to keep the blades from moving laterally.
or, if you did design/source a transmission shaft in place of the rope then the bearings could be dispensed with. I'm thinking of a giant version of a speedometer cable- a large (~3/8" OD?) metal spring steel rod in a sheath that controls it's shape instead of needing to use tension on the rope. Would be heavier than the rope version but perhaps more efficient depending on what can be accomplished with the bearings.
Hi Guys! Me and my husband we own a Jeanneau 36.2 of 1996 and this year we have mounted a vertical wind generator, it is not a marine one and many parts of it had to be changed in order to become good enough for sea conditions. Until today we are happy with it, trully not so efficient as the horizontal one, but it actually works and looks a bit weird on the boat, but its always a good way to start discussions in a new marina which we love it :D
You've got my Design Engineer brain working! Most horizontal wind turbines I see on boats have three narrow blades. Could try increasing the number of blades to 6, 8 or even 12. Could also try increasing the blade area too. For the vertical axis generator could try doubling the height of the blades or link modules together. Single tri blade unit for windy days, double for medium wind strength and triple for light wind days. Could also be a unit that has the blades sliding inside each other which could then be automatically pulled in or out depending on wind strength and also controlled automatically to match blade area with wind strength. The AC generator could be mounted under the deck with the input shaft under a flush mounting hinged, edge sealed small hatch. Would need to rotary seal the shaft but a lot easier to do that than seal the whole generator and its electrical connections. Dan, you are right about those screw terminal blocks. However I have come across a 'work around" where the strands were first crimped in a tubular brass crimp which was then clamped in the block. Second downfall of that terminal block design is that there is no provision for strain relief of the cable. Acceptable for a building application but when something can move or vibrate you really need strain relief on all cable connections. Take care and have fun!
You need a steel or fiberglass rod to make the connection between the motor and blades. You're losing too much torque in the rope. But I'm sure you knew that and were using what you had on board 😉🙃 Looking forward to this build Dan. I know it's going to be epic. 👍👍👍👍👍👍👍👍👍
Great idea, may need to concider the loads you are now excerting on the parts, I think the pulsing and resulting sqeaking came from the torsion line union, install a universal joint at top and bottom of torsion line terminal connections to effeciently deal with the off axis alignment. If you can design this to take the linear loads and buffer any rotational axis misalignment then you can make you motor mount more modular and effecient. Interested to see how this poject develops, many fundamental challenges to overcome, hoisting/lowering, balancing speed wobbles, magic smoke ...... might be worth looking into and power input controler like a Scotty from Safiery. Good luck guys, love your work. FYI - I use 'bootlace' ferrules for the screw terminal blocks (changing them out for soldered connections is better for permenent installs)
Couple suggestions. You need a thrust bearing to take the tension load (bearings in the motor/gen are not made for high axial loads) and also adding a universal joint between the torsion rope terminal and the driven shaft will help with some of that "clocking" you were seeing due to axial mis alignment. My biggest concern with the hoisted turbine is how to lower it when its fully spun up. Maybe having a "bucket" style lid that can be lowered over the turbine to effectively shield it from the wind while hoisting and lowering that is only raised up after its at full height. Interesting project.
Couple of ideas for you to think about. 1- What about getting e-bikes to get around when you are on shore for exploring and grocery "getting". They an be disassembled for transport in Coco. They have small trailers available to carry larger loads. They can be re-charged over night via the batteries. Light weight and no need to hiring cars or taxis. 2- Look into get a couple of electric pole saws. These devises have a battery pack with a 10 foot extension powering a small chain saw. If you use just the pole extension (linked together) you would have 20 + feet of a transmission rod to power the motor from the wind turbine. It would already have the necessary shaft linkage and connectors inserted into the poles. You mentioned that you wanted to start with an off the shelf idea and modify it. Again a couple of ideas for you to think about.
Love you guys!!! I am sure at some point the aluminum-graphene batteries will hit sailing. I can't wait to see what genius ideas you come up with using that technology. Also with the advances in solar collection when might you be ready for an upgrade to the panels you currently have?
Dan if you are on a boat the go-to connectors are crimp. (At least according to Florida scuttlebutt) Soldering gets corroded and the wire next to the solder becomes brittle. Nowadays they have little sleeves called ferrules. Everybody loves them. Stranded wire behaves fine in the "nightmare" connectors with the screws if you have the ferrules. Take care.
This is my absolute favorite channel/show/video to watch. I've seen every episode and to me it's better than watching any tv 📺 show. Dan can do anything. Kika always has the same can-do attitude. Best entertainment and stunning visuals I've ever seen. Sometimes I wish Sailing Uma was a tv 📺 show but then I think it would lose it's freshness and authenticity. Thanks for making this channel as well produced as any network, and IMHO it's the best.
You are motivating me to finish a wind turbine design I have. Trial and error, again and again. You are on the right track. There used to be a model that was mounted with a line top and bottom that looked like a hoop whose blades spun inside the hoop. The hoop was then "line" mounted (hoisted). The magnets and coils were inside the hoop structure so they were weather protected. There were no tensioning issues. I am not sure if these are still available but if they are it would be worth the effort. Thank you

Love the nod to Erik, and definitely love that idea of using the torsion rope as a turbine shaft, that's crafty!

Try RAN sailing in Scandinavian waters.
So true. There are very few sailing couples going to spots as exotic as this!

Holy Cow -- the opening shots in the first few seconds are absolutely BREATHTAKING!!!!!

Exactly. They truly are amazing people.
You’re content just keeps getting better and better. You guys are wonderful storytellers. Also as someone who grew up dealing with old diesel and gas boat engines I love seeing you’re real life experiences going all electric
I took a shot every time that you said theoretically and I'm headed to the hospital for alcohol poisoning😜🤪🤣
Too funny !!!!
Dan, another thing that might have even more torsional rigidity and would stay straighter would be to use some high burst test hydraulic hose for your shaft. You might even be able to put the hose inside a PVC sleeve to make it even stiffer. Schedule 80 PVC electrical conduit has a pretty thick wall. If you got really sharp you could put seals at both ends of the shaft and then put a light oil in it to cut the friction. You should be able to find some hose about the size of the bore in your coupler. If not, you could use a piece of shafting installed in the coupler and then slide the hose over it. The rubber liner of the hose could be drilled out to get a very tight fit on the stub shaft. A good hydraulic fab shop should be able to use a crimp on fitting to attach the hose to the piece of shafting. You could then do something similar at the top. You might even be able to put more tension in the hose connector to keep it from whipping against the mast. I look forward to seeing what you come up with.
Is there gearing in the turbine to spool up the RPM inside? In Sweden where I just bought a farm, have also found good quality crimp on studs that will cure your problem with the screw on terminal blocks. The smoke may have simply been the new boards burning off manufacturing residue.
One of the oddest and coollest things I have seen was walking across a beach in the Hebrides and leaving snow footprints. The beach had been covered in snow like you saw, then a storm threw sand over all the snow, hiding it until my feet broke through.
@sailinguma we are an electric sailboat in the PNW. We tried a big wind generator mounted on our mizzen mast first. It required a lot of wind to generate any usable electric over too long a period. And besides the issues you wisely mentioned, the drag was affecting our sailing, balance and steering. And those are moving parts requiring maintenance. We switched to solar only. No hydro. We haven’t plugged in since beginning of season.
Hahaha! YESSSS! You surprised us! I am so happy to see this episode! Based on our prior conversation I knew you were planning something but I didn't know you were planning to let us in on your plans so soon! I can't wait to see how this evolves. You two are sail boat pioneers! I love it! I also love the nod to More Sailing Less Bullshit Erik Aanderra! I love his channel!
Two awesome elements of this video: 1. Great poke of NBSJS 2. I have been thinking about a VAWT for my little boat as well so I'll be watching this project with great interest.
Never put soldered stranded wire into a screw-down terminal - the solder slowly flows under the pressure and you will end up with a bad connection in time. It's against electrical codes because of that. You can crimp the stranded wire into a ferrule, and put that into a screw terminal.
As a Union Electrician&live aboard for 25 years, told by an Arctic Sailor NOTHING you do stops corrosion; not shrinktube, liquid tape, solder, whatever, I prefer thick solid wire in a bent loop, but I'll take STRANDED, split&twist fibers, form them around a nail or post, twist the end again forming a tight loop, and crush between stainless washers for a "LUG TIGHT" connection that lasts, knowing in 2-5 years I'll probably have to redo it. As for aluminum connectors and soldered or crimp sockets I hate them; they all rot.
24:05 (The trapped air in the sand) The out going and incoming tide is the cause, as water drains out air will fill between the sand and because of the (water service tension rule) trap the air when the tide "floods" the shore line again. What also helps a lot is that there is no or very very little wave action to smash the air out...
To smooth delivery of a "choppy" power source, you may need to implement some kind of flywheel between the torsion line and the motor. With the moving gear, you may want to enclose it in a housing. Good luck!
I agree
I love watching their modification videos. I know little to nothing about sailing but I love watching this channel. These two are proof that anything is possible with the right mind set! Keep on living the dream!
Seriously I love how Dan like just doesn't ever not modify something 😆
An Erik photobomb would have been hilarious, but at least he posted. Great episode! Love the barefoot, toqued, campfire dinner. You two really know how to live!
As usual, that was interesting. Intriguing, really. I had no idea of the size of the vanes. Dan, you truly are a magician! You make Macguyver look like a school kid. It's so nice to hear Kika's laugh, see you two again. I get withdrawal symptoms between vlogs.
Dan is the Man, and Kika's laugh is adorable,best show ever!!!!!!
Amazing guys! You both are an inspiration for sure. Not surprisingly You are going to be remembered as the ones who changed the meaning of sailing. I'll not be surprised to see a Sail Boat line by the name of UMA with the very same logo to be out there very soon in compitition with other big names.
Hats off to both of you, what a great team.
8:54 for a good reason, they are very inefficient. When wind blows through a normal "vertical" propeller, it hits all the blades at once and ALL blades transfer that force to spin it in the SAME direction. On a "vertical" propeller the wind pushes on all blades as well, BUT having a center axis means one blade wants to go in the one direction and the other two in the opposite. Yes they present a different shape when at the "wrong" side but still generate a lot of drag and Is this drag that reduces the efficiency up to 30% or more.
If you need smaller and more powerful wind turbines, pick one with more blades and less diameter.
What about the Darius design? I would expect the blades to be generating lift 90% of the time.
It also looks like a design that you could put on a mizzen mast, let spin when you are not sailing, and lock perpendicular to the boom when you are using the mizzen sail.
Love your RUclips posts. Notice there is often strong tidal currents where you go. Would be possible to anchor in the current ( or tie up to a channel marker) and use the flow to activate your regen equipment?
@@charonstyxferryman Actually it does. He's addressed this before. The regen requires about 4-5 knots of water over the prop, that's a really strong current.
I use screw terminals with stranded all the time, but you HAVE to crimp on a ferrule.
That's the only way with that type terminal. Easier and better is wago's or din rail terminals
Absolutely. DON'T solder the wire ends you intend to connect to the screw terminals. Solder is too soft and the connection will become mechanically loose and electrically unreliable over time. Yes, many people have done the soldering + screwing in the past but it's bad practise.
en.wikipedia.org/wiki/Electric_wire_ferrule yep
A simple trick to use in a pinch is to strip two or three times as much insulation to give you more exposed wire and simply fold it up to make it bigger to give a tighter fit.
I use them whole life, never had a problem, solid wire or not. They are far away from "nightmare"...
I just finished going electric in my 31,000lb 1975 Hughes 40 Ketch, I'm absolutely loving it! Just sailed it for the first time. There are so many advantages and only one draw back. Thank you for the inspiration.
Exciting stuff, can't w8 to see what Dan is gonna conjure together on the wind generator. I hope it works out looks very interesting.
Love the shot where Dan passes by with lumber and Kika is chugging behind with twice the lumber. Gr8 stuff.
Wonderful episode you guys ! Very cool. I remember as a teenager having to fetch firewood in the winter up in New Hampshire. Tried to get it to burn with old newspaper but it was just so damp . Living in Florida as an old man I don’t worry about that anymore. Have no idea how she can walk barefoot in that freezing water. I’d be complaining three days straight after that. Beautiful place you anchored at. So peaceful. You don’t have to sail to entertain us. This episode was that perfect example. Stay warm …
Love the low key shout out to Eric his channel is great.
Sailing Uma is by far my favorite tho~
Here's a possible solution for the solid / stranded wire issue on the boat. Go to Amazon and look for these two items: 1. Hilitchi 800pcs 10-24 A.W.G Wire Copper Crimp Connector Insulated Cord Pin End Terminal Kit and 2. IWISS Self-adjusting Hexagonal Plier for AWG23-10 End-sleeves Ferrule. I use them and love them! you can crimp them onto stranded wires and have a solid tip to screw the connector to - with no soldering and no fuss!
Love the channel, been watching for a really long time. Keep up the good work!
Dan ”the man” saílorised a vertical windturbine ❤️❤️👍🏼
He still is"The Man"!!!!!!!!
I love your experiment’s in wind and solar power. I can watch these type of videos for ever as I love technology with a bit romance 🥰.
I like this type of video as much as your sailing videos.
I adore this forward thinking. Electric sailing, no diesel, no pollution. I was wondering a few months ago how you could use wind on a sail boat to generate more power. I love what you came up with honestly. Brilliant. I had been thinking myself, how a Catamaran could use water between the hulls , to create more additional power while sailing. Using the same concept in rivers and stream with a small two foot water, paddle generator. Using the same concept, a small water paddle placed under the boat could create more power while sailing/moving through moving seas as you sail. There are more ideas out there as to how to generate enough power to live with, on a high level. I'm pretty sure you two will be leading this forward thinking technologies for future sailors and even bigger boats, ships, etc... Kika, Dan...Thank you.
Loved this DIY episode. Great scenery. Interesting that you left Canada to sail across the North Atlantic to enjoy a cold beach, snow on the mountains, and sit by a fire made of damp spring wood. ;)
Yeah, and then he uses British slang when he calls the terminals "rubbish" and not "proper," LOL. I speak Canadian, and have worked in England. Then we have Kiki's adorable Haitian accent. These two are so FUNNY, and smart, and put together a mishmash of amazing vlogs with absolutely beautiful cinematography. Very cool wind turbine prototype!
@@brendag2891 Agree!
No BS on your channel. Love you guys! Keep doing like you do.
I can announce that UMA sailed with 4.8 knots in good weather 11 hours ago so Dan and Kika are alive and probably feeling well.
Thank you Jan-Erik Eriksson. That is very assuring. Everyday I pray that UMA is fine since they were radio silence for some time.
You guys are mavericks in your quest for green energy solutions. I salute you. You instill a sense of hope, that perhaps there are others like you, inquisitive minds leading us all into a bright future. Thank you
You guys always seem to make it through ruff and tough times...amazing stuff guys⛵
Lovely project!
If you add a universal joint at the generator input, it will not be as sensitive to alignment between generator axis and the torsion line. In the scene 03:48 you have made a yoke coupling out of a tube, the slot is at 90° to the first bolt hole, try leaving that bolt, through the generator shaft, slack so that the coupling can rock a few degrees and that should do as a mock up.
I agree with the comments about a thrust bearing, the tension on the torque line was possibly causing the generator bearings to bind, hence the squeak and slow running. The generator's bearings will probably designed for rotation only, with no provision for thrust.
l love taking things and adapting them to suit a new purpose, good luck... hopefully you will create the Uma class generator, which we will soon see on every clever yacht.
Dan , inside your typical gas powered weed eater - lawn trimmers
they have a flexble square metal cable that spins inside the tube running between the motor and the spinning head . It might give you less flex if you used the whole assembly.
Ahh yes, good point. You could potentially use two straight shaft variety trimmers and couple then together. Be cool if some old trimmers could be found at the dump or junkyard.
This is similar concept ad speedometer cables from cars I believe. Idk if they would be stiff enough to transfer the load, but similar concept.
Just a few things to consider for the wind generator. The unit you have is way to big for what you are using for a wind rotor. Look at most pull behind aqua gens and you notice they use a small diameter generator section. That is because they cannot create a huge amount of torque to spin the gen . With a wind gen you have even less torque so the gen has to be small. You have to trade off torque for RPM. With a smaller gen it can rotate in less wind.
With the torque line mount all you need is a straight coupler that mounts onto the gen shaft. Then you swivel the gen where it mounts to the deck to line up with the torque line. Also you want a gen that is at least 3 phase to even out the pulses from the gen spinning. No wind gen is going to delivery huge amounts of power at one time. But it does give power 24/7 as long as the wind is blowing.
Just a thought, TP
I like this from the title, actually. It did not disappoint, as usual.
There seems to be no reason to *not* have a series of those vertical axis blade sections linked and hoisted by a single jib halyard, like a sail, pinned to a generator on deck (or below) able to fully capture that torque. I am sure blades could be fashioned to compensate for the tilt if it's an issue.
I wonder how easy it is to trim and curve some plastic sheet into blades and clamp them to that torsion rope...
Nice.
I just got a new smart TV. Felt good watching Uma on the big screen. Couch life is getting better.
Choc blocks for stranded wire are fine to use but you must use crimp ferrules on the end of the wires. Makes a great connection then.
100 % correct ,but then Dan knows everything
^^^ THIS
Crimp ferrules on stranded wire.
@@Mechone11 wow. that's a little salty
@@steveqhanson6835 let's just say people that have met them weren't impressed
Spectacular photography! Good to see that the wood stove is in use. Great creativity and teamwork. You may already have these ideas in your wind vane "options" list: #1. Use a metal/plastic tube/pipe rather than the flexible torsion line. In concept, this would be similar to the threaded drill pipe used for water/oil drilling. Use 1/2" or 3/8" tube, 4' in length threaded at each end. Easy to assemble and store. #2. The wind vane appears to be about 2' high and 3' in diameter. Consider stacking several wind vane segments to increase the torque.
I'm sure you will figure out a manageable way to use your wind generator. Il definitely give you props for being adventurous and trying new things. "Nothing ventured nothing gained". ⛵
I did a fair bit of work with wind generators at one time and I came to the conclusion there is no substitute for size. Small ones make more noise than power and although they seem ideal for sailing boats they really are just a novelty item that produce a token amount of charge.
That 'motor' as you call it is the alternator, it needs to be spinning more than 1000 RPM to get a reasonable amount of power and as you know the wind is never constant. It also probably will not stand up to a lot of tension being put on the shaft, pulling on it like that will wear out the bearings very quickly. Also they need some type of brake fitted to stop them over revving in high winds, there are mechanical solutions and electrical. You can have a small paddle that is spring loaded which will operate a small hub brake or cable operated disc brake. Or you can set up an over volt detection system that returns power to the alternator which energises the field coils and pushes against the rotation to prevent it getting out of control. Both systems have their faults but you cannot run a wind generator safely without one.
Large wind turbines are much more efficient because they have a lot of inertia and can be geared up to produce higher RPM's which produces higher voltage and higher power, small ones are only any good for lower voltages, less than 24V and low power.
Ha. Love the reference to certain norweigian sailor. :P
That guy is awesome 😎
But I have to say. This is one of the coolest DIY-things on sailing channels ever. Looking forward to see it working properly - and add one onto my plans as well!

I watched this in August, during a heat wave and wildfire smoke here, and never has the time lag of videos been more refreshing LOL The snow on the mountains, your winter clothing, was cooling to look at.
Well, we are quite far above the arctic circle. This was one of the warmer days we had all 'summer'.
The BS wasn't BS at all! Resourcefulness along the way.
First of all let me say you guys are amazing my wife and I have been watching you since you started we're an older couple and bought a 38 ft Ericsson sailboat unfortunately we don't have the drive that you youngsters do but everything that you have done to your boat is simply amazing. Also everything that you've done to your boat is exactly what I had intended on doing to mine I have a wind vane ready to install just like yours I want to do electric motors just like yours I want to do battery Banks just like yours and I've been studying wind turbines and thought about doing twin vawts on the back at the radar Tower one of the things that I thought about and making a vawt was to do counter rotating blades so that slower wind speeds would create twice the energy instead of just one stator you would have two going in opposite directions because the blades would be going in opposite directions counter rotating squirrel cages so to speak just a thought.
Just want the algorithm to know that y'all's s content is incredible.
It's the best!!!!!!
Dan, I love boat work episodes, they aren't bullshit, keep em comin! As much fun as it is following where you're sailing, its fun to see the projects too to fantasize about what I'd do on my boat if I ever get one.
Just a thought about the squeaky motor. The motor probably doesn't have the necessary bearings to deal with the linear tension of the torsion line.
Exactly, need to install a load bearing plate with coupling above the generator to take the load off the generator bearing.
The squeak was from the fitting I made. Also, most sealed bearing can handle a small thrust load, if they’re installed properly. But that motor isn’t going to be staying long.
The bearings in the motor are probably just as good as the instructions
@@SailingUma think you need something like a CV joint then it dosent have to be perfectly alignet
Build in an intermediate bearing to take load off genetator bearing. Use this pyramid housing to bolt to deck with.
Brilliant Umaneering! I love how whenever you come across a problem that would seemingly involve something that doesn't exist you just go and invent it - no engine, use one from a forklift. No wind turbine or one too noisy - put up with it no.. invent one! Just wondering though - could you put more than one of those wind turbines above each other to improve the sail area - potentially generate more power in lower winds and shorten the tension wire (great idea by the way!). Have to mention the techical side of this video and the editing - I always love your videos, but this was great - starting with a beautiful sunny drone shot of Uma looking as if she was in the tropics before panning to show Norway, brining it all back to a caribean/norway barbaque at the end was brilliant, although poor Kika's feet! Great title too, lovely nod to Eric :-)!
"Umaneering"! Love it!
Your projects are why I subscribed. Thanks for posting the "bs"!
Having a garbage truck of memories I can remember something that should be of assistance. About 6 month to a year ago I was surfing YT about hydroponics and came across this guy who was heavily into designing his own systems. He designed his own Wind generator like yours except fixed with a solid connection. The thing is he went from a prototype to something that produced approx 300 watts roughly 10 to 20 times his initial output.
This was not by making it by making it bigger but his generator was a round horizontal disk rather like a plate and like plates he was able to stack the Stator's slightly offset on top of each other.
Wish I could remember the video it was a brilliantly simple engineering solution and very compact, though of course this term is relative when you live on a 30 odd foot sail boat
I know if anyone can make it work, you guys will!!
Inspirational 👍
Great video as always :) Love the NBJS Reference and message from EA!
Vertical wind turbines... You are creating a brake and wear point by pulling on the spindle like that, consider a solid bar so there is no tension between the vanes and generator. That way you can focus on steadying the vanes top and bottom
Arent you putting a vertical load on the bearings of the generator/alternator? My guess would be that putting tension on the axle that way will wreck those bearings in no time.
How ironic, the most relevant topic you have ever covered to date. My passion for sailing is all about self sustainable green living. This is the kind of thing that got me to follow you two. Love it !!! Keep it up !!!
1:00 noisy?
1:40 horizontal axis problem. Pretty noisy.
2:40 vertical axis?
4:00 BRILLIANT!
8:08 not noisy!!!
13:00 lol
Great video guys.
Some suggestions....
1) Increase the length of each blade from 24" to 48" tall.
2) Decrease the curvature of the blades by using a larger diameter of PVC pipe.
(These two changes mean the overall blade diameter would be smaller and could increase rotational speed)
3) Hard shaft a ten foot 6 - 8mm rod on a Universal Joint at each end with the top mounted to a sealed bearing.
4) Top bearing would be mounted to a hinged plate attached to the mast. The hinge allows for varying tension
from a backstay.
In theory this would allow the unit to remain in place in a permanent sealed and covered mount.
Just a thought,
Kirito in Providence
My favorite show! I love you guys! Let me know when you get to Cocoa Beach, Orlando. I need to meet you both!
Love your connection to NBSJS. You guys and Erik are fantastic. Some ideas about wind charging: 1) Not sure why you went with a 3 phase gen but you need to be sure your MTTP or whatever controller you have takes 3 phase input since that needs to be converted to DC. 2) you need a firm connection to the gen. How about meter long thin wall tube/pipe tied together with couplers? 3) there's probably a threshold RPM for output on the gen and that;s usually somewhere roughly around 1000rpm. You need a reduction gear or at min a large wheel attached to the windmill shaft with perhaps a fan belt to the small wheel on the gen. 4) knowing the generator's need for rpm and wattage output, look for calcs. on the mechanical energy input needed. One way to see if all this works is to find the mechanical energy conversion based on wind speed for that wind mill. Let me know if you;re interested in that. Best wishes!! Dean
MPPT controller....darn it! Not sure if that's dyslexia on my part.
I would have considered a universal joint and a thrust bearing when connecting the torsion line to the motor/generator for smooth rotation. Love the BS.

@@Neilhuny MJ left there long ago and they already met up with them, in Plymouth.
First, I love that you guys try stuff and don't get dissuaded by the nay sayers. Keep at it. I completely agree that wind and solar are symbiotic energy harvest methods. As far as the turbine goes, the reason vertical axis suffers in efficiency is that it has to drag a vane against the wind for every vane the wind pushes. So each rotation looses some % potential net energy capture. Since the total energy gained over time is an integral of the energy per revolution and the rotation speed, the small efficiency loss is magnified. Anyway, I totally get the mounting challenges of combined wind and solar. No easy answers to hard questions.
Interresting idea! The axial load on the generator will probably kill the bearings though. It was not designed for that.
That generator isn’t staying long. Like we said, it will all be swapped out as it evolves.
@@SailingUma it shouldn't be that hard to have the same system and avoid placing so much axial load on the bearings, you could have a bracket soldered to the motor chasis for tension and a rigid thin "core" to transfer the rotation, something as light as possible like a pvc pipe, so that the whole system can be disassembled when storms happen but it's easy enough to mount again the next day
I think this is a really great alternative idea. I may go with a more rigid carbon fiber tube as the "drive shaft" eliminating rope flex and tension. It could be stowed below just like a long fishing pole. Looking forward to more experiments from Uma 👌👍
Step 273 sold me on subscribing!! I just discovered Sailing Uma yesterday and binge-watched last night for hours. But the scene deep in Norway with a need to recharge was a great lure for me. I want more!!!
Renee G P at the South Sound of Washington
Love the title - you and Erik are both epic 🥰
You need a thrust bearing at the "torsion wire connection" to not kill the bearings in the generator.
... and some kind of mechanical transmission to speed up the generator.
@@Estereos I doubt the rotor has enough torque to spin up the generator with a gearbox.
I agree , you need more tension because allot of energy is going into moving the wind vanes laterally, but your generator bearings may not handle that much thrust
This has got real potential but I second that observation. The bearings will be able to take a bit of thrust but nothing like the load you have put on. A broom handle connection would keep it all in line without high tension, but then of course you will need a bearing higher up to keep the blades from moving laterally.
or, if you did design/source a transmission shaft in place of the rope then the bearings could be dispensed with. I'm thinking of a giant version of a speedometer cable- a large (~3/8" OD?) metal spring steel rod in a sheath that controls it's shape instead of needing to use tension on the rope. Would be heavier than the rope version but perhaps more efficient depending on what can be accomplished with the bearings.
Hi Guys! Me and my husband we own a Jeanneau 36.2 of 1996 and this year we have mounted a vertical wind generator, it is not a marine one and many parts of it had to be changed in order to become good enough for sea conditions. Until today we are happy with it, trully not so efficient as the horizontal one, but it actually works and looks a bit weird on the boat, but its always a good way to start discussions in a new marina which we love it :D
Was gonna watch anyway, but the Erik Aanderaa reference put the hook in!
You've got my Design Engineer brain working! Most horizontal wind turbines I see on boats have three narrow blades. Could try increasing the number of blades to 6, 8 or even 12. Could also try increasing the blade area too.
For the vertical axis generator could try doubling the height of the blades or link modules together. Single tri blade unit for windy days, double for medium wind strength and triple for light wind days. Could also be a unit that has the blades sliding inside each other which could then be automatically pulled in or out depending on wind strength and also controlled automatically to match blade area with wind strength. The AC generator could be mounted under the deck with the input shaft under a flush mounting hinged, edge sealed small hatch. Would need to rotary seal the shaft but a lot easier to do that than seal the whole generator and its electrical connections.
Dan, you are right about those screw terminal blocks. However I have come across a 'work around" where the strands were first crimped in a tubular brass crimp which was then clamped in the block. Second downfall of that terminal block design is that there is no provision for strain relief of the cable. Acceptable for a building application but when something can move or vibrate you really need strain relief on all cable connections. Take care and have fun!
I'm sure Eric got a laugh out of that. I love his channel as well.
Spectacular scenery. Makes a nice change from the typical tropical shots that seem to flood sailing channels.
You need a steel or fiberglass rod to make the connection between the motor and blades. You're losing too much torque in the rope. But I'm sure you knew that and were using what you had on board 😉🙃
Looking forward to this build Dan. I know it's going to be epic. 👍👍👍👍👍👍👍👍👍
I’m a 60 year old bus mechanic in San Jose ca. Thank you for this adventure.
I've been following along for a while. I had to re-watch the Queens Bath step to warm up for you
Love the homage to Erik and NBJS! I watch both unique sailing channels. Amazing content. Gorgeous scenery! Thank you.
Loved the sneaky intro. Stunning cinema photography.
Great idea, may need to concider the loads you are now excerting on the parts, I think the pulsing and resulting sqeaking came from the torsion line union, install a universal joint at top and bottom of torsion line terminal connections to effeciently deal with the off axis alignment. If you can design this to take the linear loads and buffer any rotational axis misalignment then you can make you motor mount more modular and effecient. Interested to see how this poject develops, many fundamental challenges to overcome, hoisting/lowering, balancing speed wobbles, magic smoke ...... might be worth looking into and power input controler like a Scotty from Safiery.
Good luck guys, love your work.
FYI - I use 'bootlace' ferrules for the screw terminal blocks (changing them out for soldered connections is better for permenent installs)
Have you run into Erik? Quite the character!
Couple suggestions. You need a thrust bearing to take the tension load (bearings in the motor/gen are not made for high axial loads) and also adding a universal joint between the torsion rope terminal and the driven shaft will help with some of that "clocking" you were seeing due to axial mis alignment. My biggest concern with the hoisted turbine is how to lower it when its fully spun up. Maybe having a "bucket" style lid that can be lowered over the turbine to effectively shield it from the wind while hoisting and lowering that is only raised up after its at full height. Interesting project.
I actually choked when your video popped up on my phone and I read the title. Funny.
Couple of ideas for you to think about. 1- What about getting e-bikes to get around when you are on shore for exploring and grocery "getting". They an be disassembled for transport in Coco. They have small trailers available to carry larger loads. They can be re-charged over night via the batteries. Light weight and no need to hiring cars or taxis.
2- Look into get a couple of electric pole saws. These devises have a battery pack with a 10 foot extension powering a small chain saw. If you use just the pole extension (linked together) you would have 20 + feet of a transmission rod to power the motor from the wind turbine. It would already have the necessary shaft linkage and connectors inserted into the poles.
You mentioned that you wanted to start with an off the shelf idea and modify it.
Again a couple of ideas for you to think about.
Love you guys!!!
I am sure at some point the aluminum-graphene batteries will hit sailing. I can't wait to see what genius ideas you come up with using that technology. Also with the advances in solar collection when might you be ready for an upgrade to the panels you currently have?
Dan if you are on a boat the go-to connectors are crimp. (At least according to Florida scuttlebutt) Soldering gets corroded and the wire next to the solder becomes brittle. Nowadays they have little sleeves called ferrules. Everybody loves them. Stranded wire behaves fine in the "nightmare" connectors with the screws if you have the ferrules. Take care.
LOL - Love the shout out to NBJS in the title!
This is my absolute favorite channel/show/video to watch. I've seen every episode and to me it's better than watching any tv 📺 show. Dan can do anything. Kika always has the same can-do attitude. Best entertainment and stunning visuals I've ever seen. Sometimes I wish Sailing Uma was a tv 📺 show but then I think it would lose it's freshness and authenticity. Thanks for making this channel as well produced as any network, and IMHO it's the best.
Interesting project with wind turbine, can hardly wait to see how it turns out
You are motivating me to finish a wind turbine design I have. Trial and error, again and again. You are on the right track. There used to be a model that was mounted with a line top and bottom that looked like a hoop whose blades spun inside the hoop. The hoop was then "line" mounted (hoisted). The magnets and coils were inside the hoop structure so they were weather protected. There were no tensioning issues. I am not sure if these are still available but if they are it would be worth the effort. Thank you
Great video guys!!! ♡♡ Suprisex you haven't hooked up an alternator to that fireplace fan! Haha!!
I’ve given it a thumbs up before I watch it, that’s how confident I am .
