Solar Tower of Power

This is one of the best solar ideas I've read about as far as large scale energy production is concerned. Termites have been using the natural convection caused by differences in temperature, etc. between the ground and a higher point. This technology could also be used to create "green" skyscrapers and could be incorporated into all kinds of large works. Of course this thing is supposed to be around 1km high so the increased efficiency would be pronounced but using this kind of energy (which could be used directly as mechanical energy, not just to turn generators) to reduce the load on the power grid produced by any large structure seems to make sense.

Oh wait, that's why we won't do it, just like we won't build these generators and we won't invest in wind and tide power. It's not going to make the ultra-wealthy mine owners, oil tycoons, or speculators more ultra wealthy. Since the only resources one of these things takes is in building and maintaining it, it doesn't provide a "revenue stream" that feeds the rich. We'll have none of that in America.
