Efficiency is a problem with today’s solar panels; they only collect about 20 percent of available light. Now, a University of Missouri engineer has developed a flexible solar sheet that captures more than 90 percent of available light, and he plans to make prototypes available to consumers within the next five years.
Infrared emissions above the epicenter increased dramatically in the days before the devastating earthquake in Japan, say scientists.
Japanese researchers working out of Tokyo University of Science, have built what they describe as a motor for electric cars that does not require so-called rare earth metals; a move that could drive down the costs for such vehicles.
Researchers from the National Renewable Energy Laboratory (NREL) have reported the first solar cell that produces a photocurrent that has an external quantum efficiency greater than 100 percent when photoexcited with photons from the high energy region of the solar spectrum.
University of California, Berkeley, scientists have shown that ionized plasmas like those in neon lights and plasma TVs not only can sterilize water, but make it antimicrobial – able to kill bacteria – for as long as a week after treatment.
A team from Yale University has discovered a fungus deep in the South American rainforest that can live entirely on plastic - offering hope for new methods of waste disposal.
