It’s called POWER. No arrangement of gears will increase power (gears induce friction, lowering power). Efficient generators turn quickly, and for wind generators this is faster than the turbine spins.
This lowers torque to the generator.
P = T * w (power=torque * angular velocity)
If the gear train turns the generator faster than the turbine, causing w to go up, T must come down to keep P constant.
P in KW, T in N*M, w in RPM
P=T*w*2pi/60
P in HP, T in Ft*lbf, w in RPM
P=T*w/5252
JUNK!

@ikedasquid Its called gearing. . . . . proper gearing is what makes any wind turbine work. They other wise don’t produce enough torque to spin a generator properly

100 mph???? are you crazy?? thats totally shaking . . . . unballanced. . . . the strong vibes will destroy it. . . .

Overall, I like this channel. . . but this vid is horrible.
Types of centrifugal blowers like these are a cheap & inefficient way to move air. When freewheeling like this they are savonius turbines with poorly shaped blades.
A connected generator will produce a force opposite that produced by the wind. Generating more power increases this force. If you can stop the turbine with your hand (like you can here) you can only produce as much power as you could produce with a hand crank!
JUNK!

Cool idea I love your video!

Thanks for sharing this. Other commenters are right, these ideas have been in use for ages and they are not dependent on having the latest technology. So, you have to wonder why, for some people, these concepts are on the verge of magic? I truly believe it’s because generations have been systematically “dumbed down”. Pleease keep the vids coming. You are forcing people to think.

you use a dynamo.

So if you ever want to light a bulb on a day when the wind is howling, and you have a longstanding hatred of birds, there is a green alternative to your nearest junkyard!

Ok the part that I do not get is that there is no change or anything to make energy, which is the hardest part. These are only run on a stick! how do you generate electricity?

oh yeah this is totally science you fucking hippie morons

I keep thinking and saying to myself. . . the Ancient people had all the knowledge of these “new” types of technology. What happened to us a progressing race of humans. These vertical wind turbines take less space and provide the same power production that the propeller based windmills can offer. The only catch is to watch your fingers and hair, but still.

A Belgian guy has scaled up this design, he made several very well working models capable of producing enough energy to run a household. Some designs work better in an urban environment, others work best in an open environment. This design operates at its best in an urban environment.
Check this out !!!

Great video !! 5* and a merry Christmas to all from the Netherlands, iT

Not very efficient if the wind isn’t blowing . . .

think about it in the long run and ill trade you my pikachu
