Engineers are nothing if not creative. Significant research is going into improved ways of storing electricity, including alternatives to the currently dominant lithium-ion battery-cell chemistry in electric cars. That includes using supercapacitors to substitute for storage batteries in some circumstances. DON'T MISS: Batteries from junkyard... Supercapacitor energy density could soar using contact-lens polymer

The increasing importance of batteries for electric cars, renewable energy, and consumer electronics has researchers looking for alternatives to the currently-dominant lithium-ion chemistry. But could one of those alternatives be a combination of junkyard scarp metal and household chemicals? That's what a group of researchers are proposing, in the... 
At least in North America, ethanol is a contentious fuel. A decade ago, it was seen as a homegrown and carbon-neutral way to use less gasoline—and federal legislation mandated that increasing volumes be blended into U.S. fuel supplies. Much debate followed over using "food for fuel," its supposed carbon neutrality and the footprint of the...
