"We've been looking at very unusual materials for the mirrors both for the reflective surface as well as the substrate that the mirror is mounted on," the company's green energy czar Bill Weihl told Reuters Global Climate and Alternative Energy Summit in San Francisco on Wednesday.

Weihl said Google is looking to cut the cost of making heliostats, the fields of mirrors that have to track the sun, by at least a factor of two, "ideally a factor of three or four."

"Typically what we're seeing is $2.50 to $4 a watt (for) capital cost," Weihl said. "So a 250 megawatt installation would be $600 million to a $1 billion. It's a lot of money."

Another technology that Google is working on is gas turbines that would run on solar power rather than natural gas, an idea that has the potential of further cutting the cost of electricity, Weihl said.

"In two to three years we could be demonstrating a significant scale pilot system that would generate a lot of power and would be clearly mass manufacturable at a cost that would give us a levelized cost of electricity ...Read the full article
