Liquid Battery Could Harness and Store Solar Energy

If solar power had a sound bite, a tagline, a motto, it would be "use it or lose it."

That’s because technologies designed to harness solar energy — for example, photovoltaics that capture photons or solar-thermal collectors that harvest heat — are not designed to store it. The sun comes out and the electricity is generated on the spot. Any extra sunlight (and there’s a lot of it) spills over the edge like too much milk in a glass, forever wasted.
