nanosolar meltdown

video of a piece of steel being melted by the Sun.

-from James May’s “Big Ideas” recent BBC show.

At the focal point, solar furnaces can achieve temperatures of 5,430 ºF (3,000 ºC). The idea is not new—coming from ancient Greece—but their potential is starting to become more relevant now as we try to cut dependency on fossil fuels.

solar power is a relatively untapped energy which is abundant. with recent developments in the  manufacturing of the collectors, like nanosolar, perhaps there is hope we can figure out cheap/open solar systems.
