MagCap is looking to boost the current power from just under 2 volts to a more useful 12 volts with investor funding." From the article: "Jim Manwell, director of the University of Massachusetts Amherst's Renewable Energy Resource Laboratory, questioned the potential of MagCap's plans. 'I'm wildly skeptical,' he said. 'I would need to see proof before I believed it. It strikes me as pretty questionable for a number of reasons.'"
