Haven't read the page yet, just skimmed but looks interesting.

Interesting bunch of ideas there, but like me, they haven't implemented them yet.

I guess if we didn't have ideas to start with we wouldn't have anything to build on though.

I had the idea of building a large tube type tunnel on the side of the mountain assuming that heated air inside of it would rise and go uphill driving a wind turbine.  I don't know if it would work or if friction in the tunnel would negate the flow.  Seems like there would be possibilities though.
