Convert Oil Wells to Solve the Solar Storage Problem

Cars That Think

Solar batteries work as a short-term solution, but not when it comes to long-term storage or to power, say, an entire city. Thermal energy storage is a known low-cost, low-risk approach for storing solar energy in the form of heat,” adds Codd. One of the main impediments to harnessing solar energy is storage.
