GE’s Power Conversion business has taken a step in testing a viable way of producing large amounts of electricity from renewable resources using superconductors running at relatively high temperatures. The company completed trials of Hydrogenie, a power generator incorporating technologies that enable highly efficient production of electricity in a small space. Hydrogenie makes use of superconductors instead of copper for the rotor windings on the motor, operating at 43 Kelvin or -230°C.
