SMART ENERGY NEWS | 'Transphorm,' a Google-Backed Startup, Claims Major Breakthrough In Energy Technology

Transphorm

     Could a power conversion module really cut energy waste by 90 percent? Google's betting on it.

Transphorm, a southern California startup backed by Google Ventures and other investors, claims to have created an energy-saving technology that, when fully implemented, will save "the equivalent of taking the West Coast off the grid."

The New York Times reports that Transphorm's Umesh Mishra believes their power conversion module, based on gallium nitride (also used in LEDs), will save hundreds of terawatt hours. Currently, conversion modules are based on silicon, which struggles to efficiently convert power at high voltages. An estimated ten percent of energy currently generated in the U.S. is lost as electricity is converted back and forth from alternating to direct current. Mishra claims that gallium nitride can do the same conversion without wasting power.
