Some of the VAWT windmills I've made.

- A collection of VAWT ( vertical ) windmills I've put together over the last few years. The Lenz2 mill is driving a Fisher & Paykel washing machine motor modified to produce power.

Thanks for watching.
@IronHorsez88 Hi IronHorse. Yes thats right, all things being equal, a larger diameter means lower RPM, and more power. Its to do with Tip Speed, or Tip Speed Ration (TSR). The ideal for a well designed turbine is 5 to 7, any lower or higher and you loose power. If you increase the diameter, and keep the same TSR, then the turbine will run slower. The tips of the big turbines are doing over 200kmh, you dont really want them going any faster anyway.
You are hardcore Man!!!
Keep on building awesome stuff!!!!
Thanks for the video.
@IronHorsez88 The bigger diameters means lower RPM, its the tip speed that governs that and it cant be avoided. But a bigger diameter also means more power, even if its at a lower RPM.
The Lenz made 40 plus watts from memory. The others were just for show. Miller would be worth while experimenting with.
@Pajes01 No, never all at once. Only the Lenz was used to make any usable power, 20 to 40 watts from memory
excellent,good work...
@mdctlew Yeah you can use a chain or gear drive to increase RPM, but there are some reliability and starting issues.
@muddymuddymuddmann Hi MUDDy. Sorry but I dont have a video of the cycloturbine from top down. Its no longer running, was pulled apart years ago. After building and testing it, I realised it was a novelty windmill, there are too many moving parts to make it a practical design. Tails on VAWT's is a step backwards, you might as well build a more efficient HAWT windmill.

The Lenz works well.
Pro's - easy to make. Con's - Hard to balance.
@CANNUCK72 Yeah the Lenz is the way to go, or the savinous.
looks like quality stuff, gj
superb!
I like your designs. Do you think Vertical turbines, could replace the current Propeller design in the commercial market??
Which one did you have the most success with - it sounds like the Lenz? I want to build a small wind turbine but the problem is this: my town banned windmills inside municipal limits a few years ago. I want to create a VAWT and make it a little more sculptural so that they will not complain. I would just like some direction before I start cutting materials!
Great video! What kind of poweroutputs they have? Which one do you consider to have best easy-to-build/poweroutput ratio??
Yeah its a bit hard to see. This video was my first, wont make the same mistakes again.
@glennl1965 thanx for the response, I've seen the Lenz in action before and it seems very efficient I was wondering what's the angle of the blades that you used for maximum efficiency. I was thinking of trying to put together a 1kw VAMT in a couple of months. and would adding 3 more blades be any help to the design?
@POMPAYPEE The Lenz is the best so far. Buts its also the biggest, not not really very scientific.
In all the vawt windmills you made, which one is the most efficient and with the most torque?
@muddymuddymuddmann Thanks MUDDy
what is your favoriate? vertical axis wind turbine?
thanks
Thanks. Though I better reply to my messages, a bit late eh!
hi did you make the minimill?
@GreenEnergyToday Hey, its a hobby.
Can't read the overlay

I enjoy watching your videos. I built a Lenz2 in a low wind area. While I'm impressed that it turns in low winds It doesn't produce any usable power at that speed. The video is from before the alternator was attached. Is it reasonable to to increase the distance from the wing to the axle and use a chain drive or gear reduction to take advantage of torque in slower winds?
