It looked like you were testing a new hearing aid lol.

Got to hand it to ya Robert, for an old fella 😜your full of energy and great ideas , constantly putting out awesome content. Setting good example for young inventors!!thank you
Done a fair bit of work on windmills here in Oz. The idea of a tail is quite simple. Just need a triangular "tail" directly behind the cone with the two fixed together on a pivot. With a little careful design the tail will counterbalance the cone. On our windmills the head with fan is designed so that the fan turns edge on to the wind, i.e parallel with the tail, in a strong wind.
The idea of having a turbine down low is great, makes for much easier maintenance and can be built with very little cost
Now Lets turn the idea on its head! Here I am sitting in 40 degree heat, up to 45 here and 50 in some of the places I work in. I have quite literally fried an egg on a shovel left out in the sun.
Put the cone at the bottom of a vertical large diameter pipe, painted mat black. Now we have venturi plus convection. The cone forces air into the hot pipe the, air heats up and we have a chimney effect as well.
Raises a couple of questions what length of pipe (related to diameter) would be needed to make this work effectively and does the turbine have to be mounted at the top of the pipe? would the velocity of air near the bottom of the pipe be enough to run a turbine.
Did you pursue this?
Back in my Merchant Navy days we would use Venturis for a lot of things, one comes to mind when we were creating our own fresh water and into your straight four inch pipe we would lead a smaller diameter pipe to suck up chemicals to add to the main flow in the venturi. As your system is at the moment heavy rain is going to set your electrical fan but if you put your fan into the four inch pipe from a 90 degrees angle the inlet of the additional pipe could have a few bends to take out the rain and just have dryer air hitting the fan.I've been hoping that you would get to venturi systems for many years as it does benefit systems in a domestic environment where we cannot have big towers etc. Many THANKS
cheers mate - but I have done a video on waterproofing these fans before
I have been designing a Venturi operated generator in my head for years , it is good to see some sort of validation off this idea , Thank you.
Very cool!
Hi Rob, If I recall, the Venturi Effect is most efficient when the inlet and exhaust are on axis.
the air flow past the exhaust is what drops the air pressure at that end of the system.
Adding the bends in the duct will also cause a loss for each turn.
There is an HVAC calculation for that.
you are right mate - but the loss of efficiency I think is acceptable for the ease of construction
@@ThinkingandTinkering Alright, now that I see you have dropped the exhaust for the impeller, the design makes more sense. 👍
When you mentioned adding a fin to spin the cone into the wind it reminded me of windmills. On older windmills the fin also had a fan that was connected to a gear set to assist in spinning the top. The blades of the fin were paralell to the fin so either direction of the wind would cause the fan to turn in a different direction and a worm gear spin the top section.
would work well I think mate
Very intriguing! Opens up all kinds of possibilities! I am looking forward to your further development videos.
cheers mate
Great stuff! I like the idea putting a fin on top so it will turn with the wind.
cheers mate
Loving it! ❤️
cheers mate
Well done :)
My mind goes to a "what if you ran this down to a dyson style air multiplier?" (their so called "bladeless" fans) Don't know if that would be good for turning a larger turbine, but it seems like it would make for an Excellent passive ventilation system (obviously you could just do it with the pipe but that dyson design moves a lot more air than a regular fan) You could get your venturi up above the roof where the breezes are, down to a window box. Might be particularly good in like barns, warehouses, shops and things, to save on having to run a fan all the time.
Could maybe be adapted for more efficient attic ventilation than a whirly-bird as well.
I am going to look into that mate - that is a nice idea - cheers
Very cool!!
cheers mate
Another great video on capturing wind energy 👍
Glad you enjoyed it
See that you have managed to acquire a couple of mixed flow impellers! 😁
yep
Cool. A sousaphone turbine!
lol
I immediately thought of retro fitting in older houses that have multiple disused chimney stacks, not sure how to exit it though.
It's a great shame the the electricity companies here in UK don't allow wind generation to be tied in to the network like solar, lots of smaller turbines feeding the network locally makes sense. Thank you for the video, I'm off to watch cone crazy, take care and stay safe, Mike.
that's clever mate - I like that - great idea in fact
Interesting, as you could use this for heating or cooling depending on how you put adaptable accessories to use. EX. Solar/thermal Heating in Colder Climate, Exhaust for Cooling in summer alongside the buried pipe idea. Problem with this I see here in states is most chimneys are not maintained so have been deteriorating and are either replaced with pipes or electric heat. Makes the juices flow, thank you never looked at that option b4. Be in peace God speed.
Reminded me of the years when coal fires were the norm.... occasionally atmospheric conditions conspired to blow down the chimney and fill the room full of smoke!! 😂
I should have scrolled down the comments- I’m a year late to this video and I had exactly the same idea re chimney stacks
In terms of efficiency, how does the output compare with just mounting the fan at the small end of the 30 degree cone?
Could the cone be mounted on a pole and allowed to swivel like a weather vane with a long tail to align the cone to face the wind?
Thanks. Yes and can you add the fans as a stack and wire them up!?
I would think so
What if the exit cone was 90 degrees turned that the prevailing wind blew across it? Would it create a Bernoulli effect actually pulling the air through as well as pushing in from the other cone?
Very cool. This means that you could connect 12 upper cones at 30 degrees to get the wind at any point. I guess you would need to ensure that they meet at some point down the tube to make sure that they cannot cancel each other out (if done with multiple tubes).
Just put the whole thing on a roundabout table...
This is essentially the Invelox system (6 receptor intakes).
The Invelox system diverted all flow paths downward to the central duct. Air passing straight through would reverse flow direction essentially being like the AeroMINE system (venturi) referred to in a previous video.
@@chrispollard6568 Potentially this is the correct synopsis... whether entrainment due to the downward flow would counter this effect remains to be deduced.
Your down pipes just need to twist around like cables to make the 180 degree transition.
To use a wind collector cone makes sense to me, but does it make sense for the outlet cone? It seems to work well without. Is there a significant change in outflow if you use it? Or is it jut to protect the fan itself?
I think it is suppose to reduce air turbulence - but I agree with you
That ancient persian wind mill from about 600 ce seems like it would be most efficient the way the way narrows the wind.
You have a couple of bends in your pipe which will affect the speed of air passing through it ?
What's the inlet to throat ratio of the venturi and whether the air velocity increased as per venturi effect or not. That should be measured.
I’ve been thinking could you use an air multiplier on the exit? For extra drafting
nice
If the top cone was attached to the pipe on a revolving section with bearings.. and you had two small sails attached to the cone the sails would catch the wind and spin the cone around to the optimum direction to maximise full wind potential.
A drag connection would work, bearings don't as much unfortunately.
If it turns a few times the cable would get snagged and eventually snap.
I'm thinking the same too. Basically it can be rotated around like wind turbine tower
thanks for the suggestion mate
Like it! Will you test different cone lengths?
Cone length is critical...
gradient needs to be shallow otherwise pressure will not accumulate in the tube at lower wind speeds.
I do have few ideas mate cheers
Where does the 5 degree come from? When you pulled the cone at the end off, the LED looked like it functioned the same and made no difference if the 5 degree cone was there or not. any thoughts on that? Is it to try assist in the venturi?
Sigo vc á muito tempo gostei da ideia parabéns abraço de Portugal.
wow - obrigado meu amigo
Would the air pressure while trying to exit the fan back up and load the top cone, as you will be slowing down the air flow. In my head the loss in air speed or pressure change is the energy you are extracting. But i may be wrong, but the electrical energy must be the affect of losing something in the air stream.
1000’s of uk homes have redundant fireplaces and chimneys- a swivel cone collector something like this could be fitted at the top of them ducted to a turbine to charge up batteries all of which could be designed to be installed within the chimney space.
Cool. Though, just wondering ... like wouldn't it be nicer to use the pressure component (faster wind lesser pressure)? Thus drawing air from underneath to run the turbine. Just a thought really, I've not experimented.
That maybe a better way. Friction should be less that way and wouldn't need a tail to keep it lined with wind direction, only the swivel joint. Less parts.
nice idea mate - want to try it?
@@ThinkingandTinkering would love to but my life & room is a real mess right now. but yes, soon definitely ♥
what does the bottom cone do?
since air has energy extracted out of it, it will slow down and spread out to a larger diameter flow. the gradual transition in a cone shape prevents it from becoming very very turbulent in the process, which would reduce the flow rate of the air throughout the system down to, in worst case, almost zero
What is the exit cone actually for?
I think it reduces exit air turbulence
I think that if you use only the main cone you getting a better result because the pipe with elbows creates resistance in the airflow.
That is interesting, I see the purpose of the top cone, but I don't understand what the one on the ground is doing?
me neither - I was just replicating
Air that has flowed through the fan is moving slower than before. The divergent cone allows it to disperse gradually and not cause a restriction which would negatively affect the system efficiency.
Tubulair-windmill😄
The exit could also create a vacuum, to suck more wind.
nice
Would more air pressure be made if the pipe was tapered
Could the outflow of cold air from the horn/turbine construction be used for refrigeration?
It wouldn't be cooled until it's expansion in atmosphere...
I haven't measured a temperature difference mate - I am guessing whatever difference whether hotter or colder is going to be slight at best - but I am guessing - so worth a measurement or two for sure
@@ThinkingandTinkering The gradient wouldn't be significant enough without higher pressures, one might think, but still worth checking...
If the fan is mounted on top of a pyramid shape, you should be able to exhaust straight down, reducing losses in flow rate due to bends in the pipe.
Also, Veritasium did a video about a car that sails faster than the wind. Could you harness that principle to spin an impeller or omnidirectional fan above the intake?
wouldn't that mean putting the generator portion up in the air? Sort of defeats the purpose a bit if it does - the loss of efficiency is taken to ease maintenance - I figure that's a fair trade off myself
Slightly bigger fan partly inside the output cone?
go for it
ARE they not not loosing some efficiency placing the exit of the turbine into the wind ? A linear line would work better I think ?YOURS is better I think.
oh for sure mate - but the pay off is ground level machinery and easy maintenance - everything comes with a cost for sure
This could be useful to move air near an AC installed in a dead zone. I've seen the versions where the turbines are located on the ridge of a roof. The angle increases the wind speed there. That's basically how they cool roofs down in California..roof turbines. And they work, just not much of extractable power. But I'm pretty curious to see how much you get. For perspective, a single 12v fan powered by a 100w solar panel would do like 20 times more than a passive turbine working due to air flow or pressure from the hot air in the attic.
I have heard about them but never really looked into it - I really must
Can you do a stack effect generator, natural draft, and maybe with a small heat source at the base as an alternate to natural draft? This of course would not be wind generation. Just a thought that came up after watching this video.
that is a good thought mate- want to try it?
@@ThinkingandTinkering
Was hoping to see a video of you trying it 😁. Draft of stack per ft. of stack = 0.519 HP(1/TA -1/TG) where H = height of stack in ft., P = atmospheric press in lbs/ sq. in., TA = temp of air deg abs, TG = ave. temp. of stack gas deg abs, D = draft in. H2O. Maybe you can take it from there 😉
With this desing you need finn on top and some rotating cone so it faces always towards wind.
There's a company that does something very similar to this but the cone opening is facing the ground and there is a sheet that covers the ground in a large area about 12 inches high and the heated are rushes up to the Fine points of the cone and there is a turbine there
I haven't seen that - this was inspired by invelox - do you have link?
Hello, just found your channel the other day and you're so awesome!! My dad likes video games not building stuff and thats okay but kinda sucks cause noone could ever teach me this stuff! Really enjoying watching and learning. Wonder if I could ask you a battery/energy related question? I will be living in the woods in a travel trailer so u can really experience life for a while, and I got 2 6volt batteries at 215ah a piece, I also have a generator and other power sources to charge phones and whatnot, but I'd like to be able to run a small 400w space heater or something with the 6v batteries, how do I figure out how long it can run for consistently? I know I will need an inverter but what size? Is a 2000w inverter overkill or a safe bet for lots of heat? I also got a battery monitor so I make sure I dont drain the batteries passed 50%! Feeling a little lost with it all! Happy new years from a confused girl in Canada! 👋🇨🇦
I know 400w would be pretty easy to set up with solar, but I am in college and on a budget so that just doesn't seem possible at the moment!
My type of engineering!
lol - awesome
Be interesting to put a section of honeycomb inside the pipe to promote laminar flow, might aid with increasing the flow rating inside the limited diameter pipe.
go for it mate
VERY interesting, I've been giving this a lot of thought since you mentioned aero-mining,
1. could you re-direct the output airflow back to the input cone to increase efficency ?
2. could you add holes into the soil pipe feeding the fan, to increase airflow further and making
it a multi-stage venturi. alot to experiment with looking forward to see what happens.
2. ...only if there is a nozzle preceding the holes - if pressure positive the holes will just cause leakage 😏
Could you increase energy output by also adding a generating fan part way done the upright tube?
@@Arachnoid_of_the_underverse From an efficiency point of view, turbines are best mounted as high as possible but the real benefit of this idea is that flow is directed downward allowing all power generation to be at a lower level - potentially multi-stage turbines could installed near the pipe exit....
I don't know the answers mate - to be honest I have a few ideas of my own for sure - but this is one of those things it would be great if a few others took up and worked on - because as you say lots of things to look at and discover
@@ThinkingandTinkering How much will the chimney effect cancel the downward draught?
I thought you were going to give us a tune!😃
create a vortex effect by adding inner vanes on inlet. will cause a suction effect possibly increasing pressure at turbine...side note that generator is being tested about 300 miles from where i am located. quite interesting build..keep up great work God speed
a reverse rose pattern possibly
You may look around for two 45 degrees elbow and maybe black box And the led inside
@@chrispollard6568 Possibly but if air is like water then I think it would be worth testing different variations. Kinda the whole reason for the funneling effect to begin with. But if you could induce more suction somehow you would increase the pressure at the vortex point. Thus why I suggested a reverse rose possibly.. Like a rocket stove with a vortexing plate . Be in peace God speed.
@@clint9344 Vortices prior to the turbine could improve output. The angle that flow impinges on the blades is critical... angled stator blades are employed in gas turbines specifically for this reason.
@@cwt5654 exactly.. so is it possible to move the vortexing point in its location n to what degree..just my thoughts
It's a great idea, have a cone at the top of your house Where the wind is stronger and have the turbine at ground level. It would be really interesting to see what sort of output could be had with a large cone and a 300mm pipe. Or have a row of them.
Have you tested it now?
Nice
cheers mate
reminds me of windtraps from the dune universe
I would worry about snow plugging it up in my area
We have been sitting at -40 C for the last 3 days and snow is a great concern
yep - snow would be an issue - any ideas on how to solve that problem?
@@ThinkingandTinkering recirculating heat loss from the house? or wires attached to the cone like they do for icing wires on roofs of buildings? Not sure how the Company you mentioned are dealing with it. Something may have to look into for northern climates... Be in peace God speed.
yeah... an intermediate 30o folded tarp cone with 6 foot+ wide orifice, fixed to the metal fence with bamboo & diy plastic string as your collector...
-then the Big one ,luke makes a bamboo -*-box kite-*- , 2 or 3 flexy pipe &/or diy tube from ironed tarps & frans friction welder feeding a 12v car lamp & slapped together battery-
I like that mate - cheers
I'm not sure what the point of the tube between the two cones is. Wouldn't it be better to have the two cones with the fan in between them?
Imagine living next door to this man and seeing him in the carpark with his funnels and inventions, you be thinking now what's he fekin doing lol,.
I believe one should create wind, using the elements of heat (source; house roof) + cool air to develop a wind draft, combine effort with natural wind. Especially in warmer sunny climates.
nice ideas mate
I guess 5 steps further your'e connecting a lot of
pipes to the wind wall :)
lol - I love where these things can go - I do have an idea or two - of course!
What happened to your air foil project?
still on going
If the upper cone is free to move a 360 degrees with big Church Roostertail! get the wind perfect! and you might save a few £!
nice
I Designed something like this 20 years ago. All pipes went uniquely straight down to a common pipe, each with a 90° corner.
Where they all had their own a vertical one way vent. So they don't have to overcome gravity.
Not sure if the air speed is enough but i would try to put something more like he a true Dyson-Cone shape at the exit and not just a cone.
I have no idea if it makes any difference. But air-wing shaped cone feels more efficient. Next time when it's not a proof of concept.
I also scribbled something after the generator so the exit is looped back up to the cones on the backside where it's less pressure. (Also one way vents).
The 'suction' should/might make it more efficient with less resistance
nice pointers mate - cheers
Off-topic event I don't know if you did a video but what if you had a big cone or like a big bowl And on one side of it you make it higher than the other side with a rim thing and then you put some floats on it and you figure out where to float it when there is no waves with an anchor and then when the waves come they go into the bowl and down a pipe to turn a turbine The only thing with that I would think debris in the water would The one that cause problems
Anything that can be made from traffic cones has got to be environmentally sustainable. If you leave more than one in close proximity, their numbers double every day. 🙂I've heard it said that they're conspiring against the human population.
🙏👍🙏
cheers mate
Why not build two chimneys paint one white the other black with flues at the top connect them at the bottom with a length of pipe sufficient to contain the turbine buried in the ground, exploit the temperature difference between the pipes to augment the natural air flow.
The 90s will be slowing it down
I really loved this guy till I saw this video 😢
LOL Yours looks a over sizes kazooo?
yep - or hearing aid for the really really deaf lol
And now we know the dangers of being a parade Tuba player, in high winds.
Better to house the generator in the vertical section of pipe and do away w lower 90 bend. I'm not sure the exhaust cone is going to make a significant contribution
Perhaps the exitcone assist in dissapating a vortex that gets generated onthe blades at exit, that draft could brake the turning effort
I agree mate - I think the exit cone is supposed to reduce turbulence at exit - but I am not sure it is really needed right now
You are kidding me! I literally am developing a new technology based on this theory of wind collection, ducted to the turbine. My idea is to make a slightly tapered funnel of plastic (lightweight), such as trash bags seamed together, lifted with helium balloons to test, possibly a kite system for lift, or sticking it on a tall poll. Should significantly reduce the cost per watt, if my theory is correct.
Would love to know the efficiency boost from the ducting
Venturi turbine works better with water , you don't need a dam all you need is a stream on city plumbing. Also if you suck or venturi air into a water system then you also have extra power from buoyancy of air bubbles in water line ..
I don't see how you play that horn. If you put a bag on it and put it under your arm you could squeeze the bag maybe get something out of it : )
😂😂😂
lol or just put it to you ear and listen to sounds of the sea lol
More effective would be
Double funnels reversed
Twin offset fan arrays
Placed in the common wind tunnels above driveways between two houses
Would need wind break baffles to protect from gales.
cheers mate
Money no object….
2x RB211 turbo fans on the same axis
Each blade ends need rounding for silent running neighbour issues then balancing
Decent conical end bearings .
Rain shrouds but more importantly wind kill baffles for gales. I appreciate this isn’t the area being explored in the article but no one accepts the main destruction of wind power is excessive speeds I believe protection is more effective than alternative mechanical arrangements .
On a separate issue.
Technically if I place one bearing inside another…
Would the freedom of rotation be more’ slippery’???
Would a fly wheel spin longer??
@@ThinkingandTinkering chicken egg question?? Go for a Viewers vote before proving/ disproving..

I am not sure what you mean ?
This very much looks like one of those ideas where a small scale model can kind of work if you don't care about the efficiency or cost, but it is very much not practical on any useful scale. The mouth of that cone looks like about 16x area of your fan, so how much energy does it produce compared to fan without anything blocking the wind?
AFAIK there is no large version of this that has ever managed to be economical or efficient, with the possible exception of a full scale solar updraft tower, but those are still in prototype state. The reason is simple: To get that 100mm fan to turn you need, what, hundred times more material? More? If the problem you are trying to solve is how much the turbine weights and the tower will cost, it is doubtful that a many times more massive cone that also requires a more expensive tower to hold it will help you.
Most projects trying to use this idea seem to focus on "instead of 10m turbine you only need a 1m turbine!", but 1. a 10m cone is still more troublesome to build and lift up there than the 10m turbine and might actually cost more, and 2. no, a 1m turbine is not going to produce more power than a 10m turbine and trying to force 100x more wind through it is just likely to break it.
Basically, unless you have some materials breakthrough and your maintenance costs are vastly out of proportion I don't see this ever becoming anything but a toy. The solar updraft tower I mentioned involves a tower up to mile high and either a full grid scale 100+m turbine or a large number of smaller ones and would only be useful because you could build it in an area with no wind at all and it would still work.
you might want to take look at invelox - it covers a lots what you are talking about and they seem to disagree with you - me - I am just interested in it
Lol "U bend" in the USA that's an "elbow"

@@johnnorris1983 Correct... but allows intake to be mounted much higher than turbine i.e. above a roofline - which should yield overall positive benefits in a larger installation.
yes - but your comment also misses the point
interesting how when suggested ages ago, it got poo pooed but now its being used as an idea for a video.

@@ThinkingandTinkering when the original ideal you pictured here was mentioned the main point against it was "too much building to go over" and the only pushback was "turn the bottom portion into a shed" but you managed to show that this could be routed through an existing shed,
(though be aware the irony of "making a cone is too much work, while this is a LOT of work to make one cone LOL of course my idea was to use something cheap that could be used like the tops of plastic bottles and leave a flap of plastic in the area cut out for the fans to bend them back and screw them down to the screws on the fans. (2liter bottles for me.) You would not believe how many things I have made with those things, even made a way to collect rain water and trap it below ground at the roots of a garden. one top as funnel and a whole bottle with holes poked in bottom portion for below ground portion then bury it :)
@@chrispollard6568 not sure what you mean by adopted, seems there are people using the idea of a giant array of horns facing different directions that all port to a single downstroke tube into a turbine Just seems like no type is adopted than the giant turbines we see electric companies deploying as massive tall units that fill entire square miles of land fill with the blades and other used up parts rather than using something that can be recycled more easily and is out of the reach of the common person to set up and afford.
Hi if I send you a new old style tractor glow plug and the sequence to copy my now age related video ( because it's not electrolysis ) it's a neutralisation energy encased in water . Would you carry it out and show in a video . Address to send required . For a glimpse watch joe cell horses mouth original video type all that in search . It's electro static magnetic static type ac dc pulsing energies makes a engine magnetic no valve bounce . Cheers mel in bolsover
send me a link to your video and I will have a look mate
Interesting concept. I would like to see this!!! Be in peace God speed.
Hi Clint many earlier so called water car inventors realised it's not the water but they went along with that . It's lightning magnetic neutrals the lightning bolt is electrostatic that makes the void (push apart air motion ) and the thunder the vacuum magnetic static pull/ attraction motion . It's in all energies we call atoms but tesla lord kelvin etc had an insight of vacuum energy we may relate it as anti matter . The Beirut large explosion last year portrayed the dirty knowledge of this energies potential . But in its purist form in a pressurised vessel it's far more powerful than a atom bomb . That's the problem . In the wrong hands a disaster
Clint the glow plug is stainless steel the inner is a wound s.s wire spiralling from top to bottom . The reason it produces excellent is that the energies are not parrell ( like you are shown in normal electrolysis the cathode and anode in a water filled jar parrell to each other instead the spiral inner lets the element in water attract to the element coming off the inner face of the outer positive . This then allows a type of condensed rain to vapour out . I've shown kids of 7 to 11 to copy it and they are so in awe when they themselves achieve it . It's that simple . Note the arc welding rod is solid as to use a copper wire would suffice but only one strand .as if the strands are wound within each other the current gets interfered as it goes from positive battery to source . Like cars travelling up the motorway they all have to stay in their lanes ( vander volt forces
