Scientists from the Massachusetts Institute of Technology have developed a system that can be operated at a voltage of around 12V, with a 95% recovery rate for lost power after cleaning. The waterless system can be operated automatically via an electric motor. Scientists from the Massachusetts Institute of Technology have developed a lab-scale solar module cleaning system…

Converting the nation’s 40 million acres of ethanol corn farms into solar-plus-food facilities would generate 1.5 times our nation’s electricity needs, while also powering a 100% electrified passenger vehicle fleet. Ethanol emits more greenhouse gasses than the gasoline it is supposed to replace. Additionally, ethanol (corn) farms greatly under-utilize one of the greatest resources we…

NASA will explore a large, metal-rich asteroid with an remote-operated craft powered by two cross-shaped solar arrays. This August, NASA plans to launch a tennis-court sized craft, sending it on a 1.5-billion-mile journey to the asteroid Psyche, which the craft shares its name with. The Psyche craft will be winged with two large cross-shaped solar…
