Making mirrors for the sun

With $1.5 million from the Department of Energy, University of Arizona researchers are continuing to improve groundbreaking technology to produce solar electricity at a price competitive with non-renewable energy sources.

(PHYS.ORG) “We use mirror-making technology we developed at the UA to make highly concentrating solar mirrors,” said Roger Angel, Regents’ Professor of Astronomy and Optical Sciences and director of the Steward Observatory Mirror Lab. “Our technology holds the promise of getting the price of solar energy down to where it can be used on a large scale without depending on subsidies and be competitive in the electricity market.”

"...potential to make twice as much electricity as even the best photovoltaic panels." (picture credit Lykaestria at the English language Wikipedia)
