NEW TECHNOLOGY RESEARCH & DEVELOPMENT UBIQUIT ITOUS OUS SOLAR R PANELS LS? Colorful, see-through solar cells invented at the University of Michigan could one day be used to make stained-glass windows, decorations and even shades that turn the sun's energy into electricity. ENERGY STORAGE ADVANCEMENT NTS Harvard University researchers say they’ve developed a new type of battery that could make it economical to store a couple of days of electricity from wind farms and other sources of power. Battery based on an organic molecule — called a quinone —that’s found in plants such as rhubarb and can be cheaply synthesized from crude oil. The molecules could reduce, by two-thirds, the cost of energy storage materials in a type of battery called a f flow battery, which is particularly well suited to storing large amounts of energy. 8 Source: MIT Technology Review
