(PhysOrg.com) -- Matt Scullin co-founded Alphabet Energy just one year ago, but already the CEO has ambitions of turning the San Francisco-based start-up company into the "Intel of waste heat." By harnessing the waste heat ...
Stanford engineers have figured out how to simultaneously use the light and heat of the sun to generate electricity in a way that could make solar power production more than twice as efficient as existing methods and potentially ...
