a bone to pick posted:you could save sunlight by keeping it in a chamber made of mirrors Had to explain to my brother why this was impossible. He was in his early thirties.

500 good dogs posted:We actually do "store photons" on a regular basis in a different way: inside a resonant cavity. Once the photon enters the cavity, it remains there as a standing wave (rather than traveling in a circle as you suggest). Losses in the cavity cause the photons to be eventually absorbed. To my knowledge no optical or microwave cavity will preserve a photon for more than about 1 second, and they typically can't store many photons (maybe a few billion or even trillion, but that's a tiny amount of energy). But yes, conceivably you could make a resonant cavity with such little loss that you could store a photon for a year, and conceivably this cavity could be robust enough to hold the ~10401040 or so photons that hit the Earth in a day, but realistically probably not. So nothing actually like a box of regular house mirrors? Gotcha.

Lotta people about mirrors not working at 100% efficiency. Light boxes, controversial subject, who knew?
