Solar Chimneys

Take a tower, make the base much wider than the top.
Make sure the base is open so air can get in.
Make sure the top is open so air can get out.
Paint the whole thing black so it gets heated by the sun
Hot air rises, heading out the open top, causing more air to be pulled in from the base.
Put some turbines in it, at the top or bottom.
Make it big.
Real big.

The Solar Chimney

(sigh) that video was four years old, and as far as I can tell they haven't broken ground yet. C'mon people... move it! There's a nerd in Seattle growing a bit impatient here.
