The hundreds of glass mirrors break the dusty field in Lancaster, a sea of silver in a landscape of brown.
When switched on for the first time today at an opening gala with investors, local politicians and others, they'll make up the first operational solar tower energy facility in the United States.
They reflect the sun into a tower in the middle of the field, boiling water into steam that travels through pipes to power a turbine and create electricity. The plant, created by Pasadena company ESolar Inc., will be able to power 4,000 homes.
The strength of the small field of mirrors is surprising, but what might be more surprising is the technology's source. It was established by Pasadena incubator Idealab, a 1996 creation of entrepreneur Bill Gross. Gross, whom Time magazine once called the "man with a billion dollar brain," generated some big hits with GoTo.com, Internet Brands Inc. and Cooking.com, along with such misses as Eve.com and EToys.
Idealab, which has counted director Steven Spielberg and actor Michael Douglas among its backers, has been spreading its reach to the green technology sector.
In the last three years, it has created RayTracker Inc., a solar tracking solution for photovoltaic systems; Distributed World Power, which designs solar systems for developing countries; Aptera Motors, which designs fuel-efficient cars; and ESolar.
It is jumping into the environmental market as venture capital is flowing more into clean-tech companies. Investment in such firms shot up 73% in the second quarter from the previous quarter, according to Ernst & Young, and is expected to continue growing.
The percentage of clean-tech investments to total investor funding has increased to double digits over the last three years, said Doug Regnier, an Ernst & Young partner leading its Pacific Southwest clean-tech consulting business.
Energy "is probably the biggest opportunity of the century," Gross said. "The world's energy needs and the demand to make that clean energy is going to be a challenge and an opportunity for smart entrepreneurs."
Though focused on computer software for two decades, Gross said he returned to his passion for solar energy in 2000 as power shortages loomed. The Caltech graduate bought the restaurant next door to Idealab and turned it into a machine shop, eventually running solar experiments on the roof. Idealab's first clean-tech firm, Energy Innovations, was created in 2001 to convert solar applications for commercial use. Idealab hired 50 people in the next three years to work on such ideas as a fuel-saving car and a portable solar device for developing countries.
