waste heat for electricity

Energy now lost as heat during the production of electricity could be harnessed through the use of silicon nanowires synthesized via a technique developed by researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) at Berkeley. The far-ranging potential applications of this technology include the DOE’s hydrogen fuel cell–powered “Freedom CAR” and personal power-jackets that could use heat from the human body to recharge cell phones and other electronic devices.
