Scientists working on this prototype high concentration PV thermal system believe they can produce energy as much as 3x cheaper than with comparable systems, and all with common, abundant materials.

The prototype uses mirror facets aligned into a parabolic dish, focusing light onto smaller photovaltic panels, while the whole apparatus tracks the sun to ensure the perfect angle. Developments like this are putting us on track to have renewable, solar energy with prices that are competitive even with wasteful sources of energy like coal!

How's that for some good news?
