The government's solar power tower site (Score 2, Informative)

http://www.eere.energy.gov/csp/csp_tech.html Sandia actually did quite a bit of research on solar power towers. When Bush got into power, alot of the funding was taken away. Israel's Weizmann institute actually has a working power tower that is more advanced than the ones made at Sandia. http://wis-wander.weizmann.ac.il/site/EN/weizman.a sp?pi=420&doc_id=731
