• Resumen

  • Concentrated solar power has traditionally been confined to the desert where huge arrays of mirrors focus the suns rays to heat water, oil or salt. Now, thanks to cheap microprocessors and sun-tracking technology, a start-up called Avalanche Energy is bringing it to the rooftops of ordinary houses. The firm plans to make solar water heating more affordable than ever before. Alex Pina, CEO of Avalanche, has built a prototype solar water heater the size of a satellite dish. The device, called ThermalSquare, concentrates sunlight into a beam that heats water directly, then pumps it into the existing hot water tank. There are no expensive heat transfer fluids, vacuum tubes or silicon panels.
