Google announces enormous Mojave solar tower

Not content with dominating the online space and building wind farms, Google is now looking at a huge solar energy project to bolster the green technology it uses.

The company has announced that it is ploughing $168 million into a solar energy power plant, which is being developed in the Californian Mojave desert, Nevada by BrightSource Energy.

When it’s completed Brightsource’s Ivanpah Solar Electric Generating System (ISEGS) should be able to generate 392 gross MW of solar energy.

Google says that’s the “equivalent of taking more than 90,000 cars off the road over the lifetime of the plant, projected to be more than 25 years.” It boasts that it has already invested $250 million into the clean energy sector.

The technology it is building are dubbed power towers, which work by using mirrors called
heliostats, much the same as those found in the Mojave Wasteland in Fallout: New Vegas.

When they are placed together they concentrate the sun’s rays onto a solar receiver on top of a tower.

In turn this solar receiver generates steam, which then spins a traditional turbine and generator to make electricity. The Ivanpah Power Tower will be 450 feet tall and will use 173,000 heliostats, each with two mirrors. The project is expected to be complete by 2013.

The US Department of Energy will hand out a clean energy technology loan.
