Interesting portable wind turbine -- looks like a barrel!

Heres another interesting idea for better wind gen.

For use on top of RV youd want something low obviously

Plenty of interesting stuff out there just search for Vertical axis wind generator

They may make more money selling the data collected from the cookies they just dropped on your computer.

Yep.

Just another perpetual motion machine. You can't make more energy than was in a wind segment no matter how you redirect it, accelerate it, change it. EVERY CHANGE REQUIRES ENERGY SO OUTPUT IS ALWAYS LESS THAN INPUT.

This wind turbine sounds like a 21st Century version of Newman's Energy Machine.
I'm sure it will be just as successful.

Agreed that it is interesting--but there is no data. 12 volt output....no amps range?

piano, that is a good point about jet engine turbines -- if you go to that link and look at the video, the turbine assembly looks kind of like the interior of a jet engine. Very interesting design.

Looked like the size of a trashcan...not suitable for roof mounting as shown, but a variation of the design could be incorporated into an RV.

“I can’t imagine having an oil barrel on the roof at highway speeds”

Could be a ‘show stopper’ at bridges and overpasses too - lol

If we assume it is the size of a barrel of oil, then the swept area would be limited to that dimension.

I believe jet engines use a constriction to increase the speed of the air, before mixing it with fuel and igniting it.

The constriction might allow a lower start up wind speed, but the opposite side of the coin is a reduction in swept area.

For example, an oil-barrel sized Savonius rotor with h=1 m and r=0.5 m under a wind of v=10 m/s, will generate a maximum power of 180 W and an angular speed of 20 rad/s (190 revolutions per minute). (from Wikepedia)

That's a wind speed of 20 mph.

I can't imagine having an oil barrel on the roof at highway speeds.

I would be nice to know the weight, output at various wind speed and cost.
