This is my favorite style / type of vawt. I first saw it around 1998 on a google search and it was made from plastic blue tarp. I had some blue tarp that was too sun rot to use to cover the wood pile and a bike wheel to make a nice bearing. The design had a rope connecting the tips of the "wings" that were across from each other, so that when one opened up it pulled the other one shut. I used a pipe for the rope to run through. I mounted it on the corner of the green house, about 15 feet up off the ground. It did not power anything, it just turned. And it would turn in a slight brease. It caught the wind very well. After 6 months the dry rot tarp was 1/3 strands flapping around but still turned. That thing was still running 3 years later with hardly any tarp left. So impressive.
The thing I love the best is that it needs not be steered around to face the wind.
Therefore, unlike some of the more complex designs, it has very few moving parts and no need to adjust the moving parts relative to the wind direction.
Your workshop would make Santa Clause jealous
He's moved out of this one and has converted his garage into his new workshop.
Bobby, You are nearly as easily amused as I am. Your enthusiasm is infectious
RMS, the stack of records reminds me of a vertical Tesla bladeless turbine. I always love your videos as they get me to think! More people should watch them as you are a great teacher! Cheers mate!
Very interesting Robert - thanks very much for posting 👍🙂
THANK YOU for this video! This gave me an idea for my next 3D printed project using magnets to rase the blade in the direction the wind is blowing -- more or less.
part of all this is the way we see liquid vs airflow physics, when maybe we should have them all as variants of liquid physics from viscous liquids all the way to light liquids with varients inbetween, from those dense liquids that make pools and rivers on the sea floor to the differing air densities that cause similar in the sky.
It looks very similar to the turbine you made from flapping cloth. I do like the hydraulic bearing. Perhaps magnets could be fixed to the float and coils fixed to the outside of the water container making a generator for the turbine. 👍
You would have to contain the magnets so there is a smooth surface to interface with the water. Does the golf ball dimples work the same in water as in air?
@@williambunch1365 I guess the magnets could be stuck to the inside of the float container, providing you could access the container.
Keep both container walls as thin as possible to reduce magnetic losses and the top bearings should take care of any wobble.
I was about to ask how it would be possible to use this to power something. Thanks for your insight
3:06 That bearing has lots of drag and can only hold so much weight. I use a single ball bearing in an oil bath with a shaft riding on top of the ball. Holds lots of weight and spins like a top .
I hope your videos get archived somewhere safe in case we get wiped out by a comet. So much civilization building content on your channel.
I SOOOO agree - I wish we could start as Rob M-S foundation !! (keep playing the lotto lol)
It's not easy to find but Dr. Hunts calculations are hidden behind/in that video where the front cover looks like a badly knitted spiral rope rug. on some form of vacuum valve.
Yes vertical blades
@4:17 I thought you'd never ask! ];)>
You are looking well Robert. Interesting idea to use drag to enhance efficiency.
You can use cooking oil and your bearing won't evaporate
Viscosity.
@@maw9916 Add just enought to cover the water surface.
thx
@@googleaccount1905thx
So what we are doing is creating a higher torque output at any given wind speed. Good for turning beefier generators?
Stacks of them on one pole and many poles making a wall would be logical next steps for this.
You are still my big crush Rob😃 I just posted this on twitter and suggested your channel as THE place to start learning all about .... well everything really !!! Thanks for great video, Hilary xx
Wow, thank you!
Very good. Initially when the bottle spins, more work is required to be done due to drag of water. However once the bottle starts spinning the whirling water will act like fly wheel and keep the bottle spinning, that is what I feel. Pl. correct me.
I was thinking the same, and maybe that "water flywheel" could be made in stages of sort to create a layering effect, sort of like multiple water flywheels to keep it going for longer after the wind stops.
What's also happening here is that the blades facing the wind will also have a minor thrust from the suction effect created by the wind flowing over the flaps, so there are several things going on in that device at once.
Could you make a tidal power plant using an array of underwater parachutes attached by cables to an anchored electric generator as the tide moves in it pulls the parachute quite strongly which could be used to spin the generator. Double it so you have pulling back the other direction when the tide goes back out. It would be benign to the environment as well.
Honestly from looking at his vacuum pump campaign video, it sounds less like he discovered misunderstood physics and more like a very shaky heuristic approximation of the Navier Stokes equations. (Which state that the acceleration of a fluid is due to viscous forces, pressure gradients, and "body forces" like gravity)
This doesn't rule out something new, though, as the NS equations are nonlinear, which makes it hard to actually use them beyond simplified situations or brute force computer simulations.
I'd also say that in terms of fluid dynamics, the (unmodified) Bernoulli equation isn't really the main tool one should be using. The modified version accounts for losses and gains but is still a very oversimplified model.
ETA:
Having watched a few of Hunt's videos now, I get the impression that he was self taught. He clearly is a very creative intelligent man, but there's several points where a misunderstanding/misuse of terminology or lack of understanding shows. His gravity plane idea is honestly not too controversial, for example, but fails to account for losses when recovering energy.
i have be wanting to experiment on pulse thrust by simply running a fan blade over a long tube to see what it does.
It is a neat one.
could make your buoyancy bottle into a generator. drop some magnets into the bottle. and glue them in place, and then out your coils either outside the pipe, or heck keep them cool and drop them in the water just outside the bottle.
yes you could indeed
So what fraction of the Betz limit does it achieve?
This adjustable system looks remarkably like the same one used on the SR71 Blackbird.
Rob, you video is kind of choppy and vague this time. I don't know if you ran into a legal problem with the information, but it's kind of strange, from your other videos.
Thanks, and keep up the good work.
Godspeed.
I don't understand the reference to the SR-71 😅
How much electric power could be generated by adding permanent magnets to the plastic bottle and coils to the cup?
You would want to raise the circumference and have them on the edge of the wind catching device with stationary coils obviously for more speed. Yes wobble would have to be worked on but 2 liter bottles have less drag and more volume for the magnet weight. Go for cheapest construction and not high output, and make a bunch of them turning in very slow wind speed series together to extract a decent charge capability
dpends on the energy in the wind that you are trying to capture
This makes visual intuitive sense to me. Locally, the force of the wind on the paired wings rebounding makes a steady wind stream into a linear harmonic pulse that is more self-sustaining than a static blade. The secret of resonant pulses is a key component to antigravity tech.
The common principle in a lot of the most amazing technology is variation with respect to time, fine tune control over it results in more amazing results. Especially in the electric area where the shorter the impulse duration the stronger the effect for the same cost.
Hydraulic bearing works great for slow moving objects but it's really pointless when you can just get and use a regular thrust bearing.
Do something on the LPD clean energy device 🙌✌️🙏
Do soemthing on the LPD clean energy device, dont think you've done one about this 🤔 sorry completely non related 😅 but this os new to me also 🙌 and may be practical to demonstrate as your near the seaside 🙌✌️🙏
Drinking-bird-enabled triboelectric hydrovoltaic generator ... something else for a laugh 😅✌️🙏
what is the LPD Device mate - never heard of it
'Pysics'? (Title)
Did you get my other messages 🤔✌️🙏
yep - but what is the LPD device mate - i have never heard of it
nice work on vid
It's such a shame that future generations trying to hear this incredible information are going to hear it through worse audio quality than an old-timey gramophone.
Hi. Check your title spelling...;0)
Like and subscribe, or we'll send the boys round!
All interactions require energy, all movements are energy and cheating isnt even a choice or a possibility - there is drag from air against a surface and also airs drag on other particles of the air. If energy is used to remove air so there is less pressure, this now causes other particles to gain the loss by moving into it and creating higher pressure and and so forth.
I reviewed Hunts works and could not find pieces the corroborated his works. ALL of charts and calculations appear to be his own. (I never passed physics class so the answers might be right in front of me. But, I tried to find his charts on any other web site and they are not there? For all I know (Layman) he could be simply adding an additional factor that is not there, creating a sweetened calculation? I'm not saying he's wrong, I'm saying I can't find supporting statements to show that he's right either?
* Physics-defying.
Please proofread your video opening screen.
Your video title is miss spelled. See the first 5 seconds of the video.
"Physics" is miss spelled "PYSICS" with the H missing. Duh...
All the best from the speling police.
Interesting. But, I didn't see anything defy physics. Clickbait sucks.
nothing defies physics.
Robert can say whatever he wants. You are nothing. Also the video says pysics at the beginning. Nice try though. Get it right next time.
What do you expect from a guy with a Mr Hat profile pic😡
@@kirkfrahm1252Pipe down. Child.
@@misterhat5823 try making your own content twink
robert with that you just made look at the Egyptian find in the museum that is exactly the same and they don't know what it was used for ?
