The Daily American The Met-Ed/Penelec Sustainable Energy Fund has awarded a $340,000 grant to Solarflux Energy Technologies Inc. of Berks County, which is developing a solar dish concentrator capable of delivering clean, inexpensive thermal energy for a wide range of applications. Made from low-cost, resilient aluminum reflectors, the FOCUS parabolic reflector dish follows the sun on two axes throughout the day, maximizing the capture of solar radiation. Solar radiation reflects off the concentrator onto a central receiver, heating a circulating thermal fluid. The heated fluid then passes through a heat exchanger to create hot water, high temperature steam or other high enthalpy fluids.
