Google's developing new solar tech that will drop the cost from 18 cents a kW-h to just under 5. At least, it's hoping to.
Just like everybody else, Google's disappointed by the industry's lack of innovation so they've decided just to do it themselves. At least that's what Google's Bill Weihl said today at the Global Climate and Alternative Energy Summit hosted by Reuter's right here in San Francisco.
Not too surprising. Google builds its own servers since commercial servers are too expensive. The company makes cheap janky ones and just lets its homegrown software handle the outages.Google engineers have primarily been focused on solar thermal technology. Weihl hopes they can cut the cost of making heliostats by at least a factor of two, but "ideally a factor of three or four."
"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," said Weihl.
The search engine giant started investing in renewable energy back in 2007. Along with solar thermal tech, the company is also interested in gas turbines that could run on solar power rather than natural gas--a name change might be in order.
Whatever the technology turns out to be, their main interest is the cost. They want to create a renewable energy that has a lower price point than coal. In doing so, they have invested about $50 million in the industry so far.
"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."
Google hopes to showcase the technology within a few months. It must first sustain accelerated testing to show its resistance to decades of harsh desert conditions.
One thing's for sure...I look forward to seeing what they'll come up with.
