A new concept for thermal energy storage You can charge a battery, and it''ll store the electricity until you want to use it, say, in your cell phone or electric car. But people have to heat up their solar cooker when the sun''s out, and by the time they want to make dinner, it may well have given off all its stored heat to the cool evening air.
