Interesting portable wind turbine -- looks like a barrel!

The article mentions use of this item by RVers:

Portable wind turbine

I have no idea if this is really worthwhile for the RV market.

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

Yep.

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.

โ€œI canโ€™t imagine having an oil barrel on the roof at highway speedsโ€

Could be a โ€˜show stopperโ€™ 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.

Anyone sprinkled a little mouse milk on it? I hear that works too. Large milking herds of mice take up less room than cows, and don't fart as much.


Well, you might consider re-thinking this a bit - after all just think of that LARGE herd of mice under your vehicles hood that somehow seem to โ€˜Perpetuallyโ€™ keep your starting battery charged - lol

It is a type of a Savonius rotor. It will pick up wind from any direction.

Simple designs use a barrel, split in half and then offset on a vertical axle.

There appears to be no price either.
