Actually, the sailboat thing is true in certain cases. Not downwind of
course. You can read an explanation here:

Also, and the commenter above doesn't mention, the sail acts like the
wing of an airplane and the wind rushing over the bowed side of the sail
causes the same lifting effect as wind over a wing.

Ya hey sure ya betcha!
Why, I remember a guy that put a generator on the wheel of his EV, and drove it
all the way from Concocha to Paramonga in Peru (117 km or 72 miles), and
arrived with *more* charge in his EV than when he left. ('Course, it was all
downhill...)
And there's this guy that built the Blackbird that is like, totally
wind-powered. It can go *faster* than the wind is blowing, ya! (OK, so it's
more like a sailboat on wheels; but it works...)
Don't forget them solar raycers. They can go 60 mph powered by nothing but pure
sunlight. (Course, they's more like bicycles than cars.)
Then NASA has been using nickel-hydrogen batteries to power their spacecraft
since the 1970's. When charged, they make hydrogen and oxygen. When discharged,
they use the hydrogen and oxygen to make electricity.
