PG&E to Buy 200 MW from Space Based Solar Power Sat Company

Solar power beamed down from space will generate electricity for California homes as soon as 2016, under a new plan by a utility company to ramp up renewable energy technology far beyond solar panels on roofs.

PG&E would buy 200 megawatts of space solar power from Solaren Corp. over 15 years under a power purchase agreement, enough to power tens of thousands of homes. The utility company has begun seeking approval for the deal from California state regulators.

Solaren would use solar panels on satellites in orbit to capture the sun's power, and then convert it into radio frequency energy that could beam down to a receiving station. The energy would then undergo a conversion to electricity and feed into PG&E's power grid.

Having solar panels in orbit could provide a clean, reliable source of solar power that avoids the interruptions of cloudy days and bad weather on Earth. That tempting prospect has led NASA and the U.S. Defense Department to investigate possibilities for space solar power, despite the hefty cost of launching solar panels into orbit.

A former NASA scientist went so far as to demonstrate the radio wave transmission technology that would carry energy from space to Earth. He and his team transmitted solar power over a distance of 92 miles between two Hawaiian islands, during a four-month experiment in 2008.

No one has built a system with equivalent size and scale to what Solaren envisions. But the transmission technology is "very mature" and based on what communications satellites use today, said Gary Spirnak, Solaren CEO.

Now THAT'S a salesman.

No prototype. No hardware at all.

And as far as I can tell...no website even. Sheesh. Solaren.com goes to an Armenian company.

Damn. he's far better than I am.
