.Same thing, you still cant run a car off it.

No?

(I was working at Rolls Royce during the joint development, between RR, BMW and Alstom, of fuel cell technology, as I mentioned previously)

EDIT: It looks like I've been confusing fuel cell technology with fossil fuel reformer technology, although vehicles are currently being developed which have both 'on board', the reformer produces the hydrogen needed to run the fuel cell. The reformer can also produce hydrogen to be burned in a combustion engine. (These technologies seem to be being developed 'hand in hand'))

You really think that by pushing blades through the air you can get them to spin and then convert that spinning into electrical energy and then use that to break chemical bonds and the burn the resulting chemicals back into their original configuration and use the resulting expansion caused by heat to push a piston which then turns a shaft which pushes a 2000 pound car along with the blades on top and somehow actually GET energy from the process?

Good luck with that.

You'd probably have better luck with an electric car. [Fig. 1]

How do you start it Grenadier? Do you have to push it to get it going?

EDIT: Or do you just wait for a windy day?

Apparently it's possible to sail upwind anyway, I found this out when out on a sailing trip in 2008. You have to zig-zag your way forward, but it's quite amazing considering your average route is the exact opposite of the wind direction. Proof of overunity as well.

Reminds me of that old joke:

"How was your sailing trip out to that island?"

"It was fine, but I think the skipper got drunk while we were there, he was zig-zagging all over the place on the way back"

Modern planing sailboats can sail several times faster than the wind speed, The above link wasn't what I was looking for, the one I was looking for had three 'wings' mounted vertically, and spinning around a vertical axis. It also sailed into the wind.

The one I linked to above has a small propeller underwater, driven by the larger wind turbine. As long as the aerodynamics result in low drag, the propeller in the water will drive the boat forward (It's all about resistance)

It's actually possible that Grenadier's design above will work if the turbine is connected directly to the drive wheels via a suitable gearbox. (assuming the turbine is big enough, but it won't work purely from the forward motion of the car. It should also provide 'some' forward motion if it is as Grenadier described it, on a windy day, but losses would be greater)

EDIT: BTW, Tacking isn't 'over unity', there are two factors involved. first, the sail is set at an angle, so the wind tries to blow the boat sideways, but the keel 'cuts' into the water, resulting in a 'net' forward motion. secondly, the shape of the sail, when filled with wind, resembles the shape of a 'wing', the lower pressure on the convex side of the wing results in a force in that direction, the same as 'lift' from a wing. (That's why the 'Bermuda Rig' is better than the old square riggers.)

I saw a prototype car that had a wind turbine attached on the trunk when I was in Madison, Wisconsin. I guess it was really efficient, I have a picture around here somewhere...

NO!!!
You look at it in parts, the zig or zag works by force distribution and sail angle, then you use momentum to turn and do the same thing again and again, I've gone sailing.

I don't know about the boat thing, it might move, but I can guarantee you that there is more energy going into that system than coming out of it. Ever heard of entropy? It's a law, and it's never been broken. If you could just "get" energy, the current energy companies wouldn't still be using oil and coal and such and suppressing this, they'd be using this and keeping it secret.
