Solar One and Solar Two
Solar One is concentrated solar power project in the Mojave Desert, California. This project was based on the solar power tower technology where reflective mirrors are placed in a field and track the sun, bouncing the sun energy into a central receiver point. These mirrors are known as a heliostat and the heat generated was the working energy for turbine electricity. This project produced 10 MW of electricity.
Solar Two used a molten salt storage to help adjust for cloudy days. The salt storage was 60% sodium nitrate and 40% potassium nitrate. The molten salt also allowed the energy to be stored in large tanks for future use such as night time.
Known also as Central Receiver Systems, these this project is well documented in http://www.powerfromthesun.net/Chapter10/Chapter10new.htm
