Caltech's space solar power demonstrator has demonstrated its ability to wirelessly transmit power in space and to beam detectable power to Earth for the first time.
Caltech’s space solar program began in 2011 when philanthropist Donald Bren donated more than $100 million in support of the project. In the first demonstration of solar energy beamed to earth, his vision is becoming reality.
Funded largely by Irvine Co. Chairman Donald Bren, the Space Solar Power Project is testing the feasibility of transmitting electricity converted from sunlight anywhere on the planet.
