The U.S. Department of Energy has granted a $43 million loan to a Massachusetts-based company to prove the value of a new technology in which spinning flywheels are used to improve the efficiency of the electric grid. Beacon Power Corp. will build a 20-megawatt flywheel plant in upstate New York in which flywheels spinning up to 16,000 times per minute will act as a sort of short-term power storage system for the state’s electrical distribution system, according to the Associated Press.

Connors in an article titled “Providing Electricity Services to Rural Africa.
