Weird Wind Generator No Blades, No Moving Parts

[Music] so in a previous video we made this axial wind turbine that can be horizontal and vertical and he got lots of really good comments on about how to improve this and that set me off looking at stuff obviously and I came across a Spanish Spanish company called vortex turbine delimited I started in 2012 this won tons of awards including a massive grant in 2017 and they're beginning to put their design of wind turbine open to tests and the really cool thing about it is is it works an extremely low wind without mechanical moving parts and it captured my imagination I have to admit that there wasn't a lot of information about it cos get about half a dozen patents but he said basically what they do is they use a low wind to vine Brett a pole and that pole vibration they turn into electrical energy and I thought okay well if we think about this which is a speaker of course what that does is take electrical energy in and then vibrate this cone and this cone vibration we hear as sound and if what we do is reverse that that is vibrates a cone the coil in here will move in and out the magnet and vibrator and create electrical energy so I thought okay these guys they're doing exactly that or something similar they're taking what is essentially a speaker and vibrating zakone and I thought okay what's a good way to do that so I chopped up the curve and I glued on a stick unto the coil so now that wobbling of the stick will move the call in and out of the field so let's take this outside and have a look at it working my stick stuck on to my speaker speakers a magnet obviously so stick it on a magnetic pole now there's just about no wind today yesterday we had a little bit of wind but this thing is in fact wobbling and it's wobbling in the lightest of breezes now at the moment is generating about six point one volts when it gets a bit more it actually goes up to 12 to 18 volts I mean obviously the amps here is tiny in this little setup but it is possible to make this generate some significant camp pitch as a Spanish company is showing but there are was super cool because it's a really easy thing to do and experiment with anyone let's go have a close up look at that so here is in close-up you can see all I've done is cut out the paper cone reveal the coil on the inside and then stick that stick on with a bit of superglue onto the top of the coil that's all I've done and then connected the voltmeter to this as it's in the lightest of breezes that thing wobbles and obviously the coil then moves in and out of that magnetic field and what we have is a linear alternator okay so speaker into a generator using wind that's pretty cool but it is pretty chunky and it didn't give out much power so what we need I think is something that's much cheaper much smaller and even though it doesn't give out much power we be able to do an awful lot of them so that overall we get a lot of power and I think that's what the Spanish company are doing but years ago I came across something called the sound book I was interested in speakers and this was a way of turning any surface into a speaker what it was was an inductor wrapped with a coil piece of rubber on top of the inductor and then a big old magnet you put a current into the coil and it changed a magnetic field which made the magnet bounce up and down on the rubber then you could glue that magnet to any surface I glued it to my window a desktop attend can a book whole lot of things and in fact a reed as well and it turned all of that stuff into a speaker because that massive moving magnet bouncing on that rubber made the reed of the window vibrate in time with the signal and it was a music signal so we got music out of the window or music out of the reed and as I was looking at this I thought hang on a sec a speaker works what the sound bookwork so I got myself a bit of a nation blind it's a fast equation blind and just cut a section out of it and there's the session I cut out of it and on to that I glued a magnet as you can see I'll give you a close-up in a second then I put a bit of rubber and then I put an inductor so what we've got now is a reed that will vibrate in the wind and that's quite a large Reed obviously it doesn't need to be that big it's just a bit of a Nisshin blind well let's go get Vanna girl dr. connected up we hold that there let that wobble in the wind actually works that's ridiculous so here is a close-up of that arrangement there's the inductor with its coil in his ferrite core we've got a little bit of rubber right there that I'd cut from a sheet of neoprene rubber then underneath the rubber we've got a neodymium magnet glued onto this piece of Phoenician blind so that's what it looks like because that is just a sound book glued on to a reed so personally I thought that was awesome I mean these are just random choices I've made clearly the resonance is one of the things you're interested in so that length of reed is going to have an effect as is the material because here we used a bit of wood it's quite long I imagine we could make that much much shorter and also taper to it might help to get that vibration going on and same thing with this now what we're using here is the inertial difference between the mass of the Reed and the mass of the inductor here thus creating that bounce in the rubber and that bouncing the rubber is where the fixed magnetic field is moving nearer and further away creating a varying magnetic field so it might be an idea to hold the inductor in place and put a clip here so that the Reed is the only thing that can move that might be a really good way and again the resonance of the Reed but I can see that being mass-produced in like a mat and that mat you would go onto your roof and would be a wind version of solar now believe that's the plan of the Spanish company but it looks like it's a really easy thing to replicate and have a play around with if you use an inductor some magnets or if you use in speakers you can get speakers in any size as tons of these tiny tiny speakers you'll find in old phones and computers anyway I thought that was super interesting a really easy thing to experiment with it could be turned into a very useful product so I couldn't resist sharing it with you I hope you found it interesting and thank you very much for watching the video

Here's the company that he's referring to: https://vortexbladeless.com/

Not for sale yet, so no idea of cost / lifetime / power generated, so can't tell if it is a good idea economically. Interesting idea though.

[u/TjW0569]

The amount of power produced in ANY wind turbine is a function of the swept area.
If there's not much swept area, there's not going to be much power.

no moving parts

Literally made of multiple moving parts

[u/m00thing]

Vibrations are movements too so there's going to be some fatigue on the rubber over long periods of time. Not saying this isn't a great idea though. Roofs probably not the best position. You want them dangling so no leaves and debris get caught. I wish the Spanish company all the best.
