A solar plant that's worth its salt

Just past Barstow on Interstate 15, Las Vegas-bound travelers can eye a tower resembling a lighthouse rising out of the desert encircled by more than 1,800 mirrors the size of billboards.

The complex is often mistaken for a science fiction movie set, but it is actually a power plant that once used molten salt, water and the sun's heat to produce electricity.

Now a storied rocket maker in Canoga Park and a renewable energy company in Santa Monica are hoping to take what they learned at the long-closed desert facility to build a much larger plant that could power 100,000 homes -- all from a mix of sun, salt and rocket science once believed too futuristic to succeed.

The Santa Monica-based energy firm SolarReserve has licensed the technology, developed by engineers at Rocketdyne.

"Molten salt is the secret sauce," said SolarReserve President Terry Murphy.

It is one of at least 80 large solar projects on the drawing board in California, but the molten salt technology is considered one of the more unusual and -- to some energy analysts -- one of the more promising in the latest rush to build clean electricity generation.
