How to build 2 meters large wind turbine for $30. 

Never read a statement more accurate

Lmaooo 🤣👌

It would be too thick and heavy

​@@10mm🎉

It will function, as long as you use an appropriate motor. So the intent doesn't matter, the fundamentals seem to be right here.

Good design, tks for your video. hope to see your next.

It actually is a turbine. Do you know what a turbine is? en.wikipedia.org/wiki/Turbine

@@lukakrulc1092 if you consider "turning in the direction of wind" to be useful work, then I gues itt technically does extract energy from fluid movement and convert it into useful work, aka the definition in that article.

@@ancapftw9113 yeah it is only a turbine if it is converting energy. A windmill on a riverbed converts hydro kinetic into whatever grain grinding process they have inside the shop. This can only be classified as a turbine if observing the spinning is "useful work"

@@zIVeNomIx I agree, we already have here useful work. It is in the spinning axle. now it can be transferred further for whatever you need, grinding grain, pumping water, or making noise to scare the birds. but if we look further into that wikipedia article wee see that there are different types of turbines, one being wind turbine. and that has its own definition, in which is state that is converting winds kinetic energy in electricity :) So Ancap is right, because this wikipedia entry is wrong ;)) The title should have used the term windmill. Or wind engine :) en.wikipedia.org/wiki/Windmill

kids' stuff.

it's stated in the video "900mm long, 135mm wide at the root, 45mm at the tip.." shape the profile as you like. but ensure the leading edge is cut along the axis of the tube as shown @1:15

it looks like the nuts are nylock nuts, which have a nylon core inside the nut, which bites into the bolt, they rarely come loose

then put a generator in it

or a least some bicycle gear and chain at least for pumping water.This way it could be some efficiency testing. That curve may be enough for spinning, but how much power actually collects?

Cost 40 bucks than..

Robert Tomkinson - Did you read the description?

a ratio. It's stated in the video "900mm long, 135mm wide at the root, 45mm at the tip.." That's 20:3:1 (20 x 45 =900, 3 x 45 = 135)

"wind spinner".. there's no turbine in this build

you mean the generator. the turbine is actually the motor. en.wikipedia.org/wiki/Engine but true, due to modern windmills, the definition got twisted. even wikipedia states that wind turbines consist of an rotor and a generator. BUT, the rotor itself is actually the wing turbine if we look carefully at the original definition of a turbine.

Very good video for reference so anybody can add a generator and have some power. Thank so much
