PS20 is the world’s second power tower plant in commercial use.

With a power capacity of 20 megawatts, the new PS20 solar power plant will produce enough clean energy to supply 10,000 homes, and will avoid the emission of approximately 12,000 tons of CO 2 into the atmosphere that a conventional power plant would have produced.

PS20 consists of a solar field made up of 1,255 mirrored heliostats designed by Abengoa Solar. Each heliostat (visible in the bottom left of this photo), with a surface area of 1,291 square feet, reflects the solar radiation it receives onto the receiver, located on the top of a 531 feet-high tower , producing steam which is converted into electricity generation by a turbine.

we’re sure these solar panels don’t power the whole car, but it was a neat idea.
