Solar Energy improvements
Technology Improves: Each day the suns sends over 1,000 watts per square yard to the Earth’s surface, but current solar technology can only convert 20% of that to electrical power.
Physicists at the California Institute of Technology are working on designs that could raise that number to 50%. They hope to do this by absorbing more of the spectrum of light. These new innovations could be the next big step in renewable energy and will also be a great boost for solar attic fans.
