Information on the science & technology @ wikipedia here:

http://en.wikipedia.org/wiki/Solar_updraft_tower

("solar tower" is the term Enviromission uses, but it's ambiguous with a more common solar-based energy source: concentrated solar, which uses towers too).

N.B. I personally (and others too) disagree with the math in the "Financial feasibility" section of the wiki page, but I'm not a wikipedia kinda guy. There are other sources that show Solar Towers to be the most cost effective renewable technology available today, even with the gains in efficiency that solar PV has made in the past years.

Worth noting that the worlds largest operational solar energy installation (?) is in Spain (Andasol), and is HEAVILY subsidized by the Spanish government to the tune of something like 25 cents/kWh, which is ridiculous.
