Caveat: My brain goes on red alert when the particular substance they used - azobenzene - is named, but hopefully, they will find other molecules (of benign substances) that will also act as photoswitches.
That said, this is a new technology for heat storage. I thought this was interesting enough to include here.
Meet 'photoswitches,' a breakthrough set of materials that act as their own batteries, absorbing energy and releasing it on demand.
The next big thing in solar energy could be microscopic.
Scientists at MIT and Harvard University have devised a way to store solar energy in molecules that can then be tapped to heat homes, water or used for cooking.
The best part: The molecules can store the heat forever and be endlessly re-used while emitting absolutely no greenhouse gases. Scientists remain a way’s off in building this perpetual heat machine but they have succeeded in the laboratory at demonstrating the viability of the phenomenon called photoswitching.The full article is here, (with a misleading title) Scientists Discover How to Generate Solar Power in the Dark (http://www.theatlantic.com/technology/archive/2014/04/scientists-discover-how-to-generate-solar-power-in-the-dark/360679/) The "power" is heat, and it is being stored, not "generated."
