Spread over an area of 400 acres, the Nevada Solar One is a massive project built in the hot and dry desert, just south of Las Vegas. The plant uses 760 parabolic trough concentrators with more than 182,000 mirrors that concentrate the sun’s rays onto more than 18,240 receiver tubes. The projected CO2 emissions avoided is equivalent to taking approximately 20,000 cars off the road annually. It is a refreshing site to look at. I, for one, can't wait to fly a solar-powered aircraft. This image is a part of a large project documenting our transition to clean and renewable energy.
