A microturbine developed by Capstone Turbine Corp. was used in a demonstration project to generate electricity using solar power. Working with HelioFocus Ltd. in Israel, heliostats focused enough sunlight energy to power a Capstone microturbine attached to an optical tower. This method offers higher efficiencies and uses less land than traditional solar photovoltaic systems, Capstone officials said. “The value proposition driving this joint product development effort between HelioFocus and Capstone is that it gives solar projects the capability to generate energy more efficiently during the day and to continue to provide energy at night,” said Capstone President and CEO Darren Jamison. “Efficiency is extremely important in solar power systems as a means to reduce size and space, and ultimately drive down installation costs.” Mark R.
