eSolar

Happy Birthday, America!
eSolar has developed a breakthrough power tower technology to make solar energy competitive with fossil fuels for the first time in history. Our approach uses small flat mirrors (heliostats), a revolutionary control system, and modular architecture. The eSolar solution employs a field of sun-tracking heliostats that reflect sunlight to a thermal receiver which powers a steam turbine to produce clean, renewable electricity. In this process, computerized tracking focuses 24,000 mirrors individually throughout the day with unprecedented pointing accuracy. To celebrate Independence Day, eSolar's Sierra SunTower power plant has employed this high-precision technology to declare energy independence. Happy Birthday, America — welcome to a new era of solar energy.
