New Ways To Improve Batteries


Researchers around the world are racing to develop more efficient, denser, and safer battery technology, and they are reaching far beyond where research has gone before. Much of this is being driven by concern over exhaust from internal combustion engines, which are responsible for a significant portion of global CO2 emissions. Nearly all carmakers today have announced plans to develop batte... » read more

Energy-harvesting shirt Engineers at the University of California San Diego developed a 'wearable microgrid' that harvests and stores energy from the human body to power small electronics. The microgrid consists of three main parts: sweat-powered biofuel cells, motion-powered triboelectric generators, and energy-storing supercapacitors. All parts are flexible, washable and can be screen pri... » read more
