Scientists from Stanford University have successfully stored light using semiconductors ([see link --admin])
combine this with an idea like LiTraCon ([see link --admin]) translucent building materials and you get walls that store light and then glow when it gets dark.
I wonder how light switches would
work...

According to the article, light pulses are "held essentially in place for tiny fractions of a second," so you probably won't get much reading done after night fall. |
|
| |
Use a solar-powered torch instead. |
|
| |
Yeah, or cover your house with solar panels. Those *are* light storing walls...kinda. |

yes i realize that they stored light for less than a second but i also assume that they were storing the light in something a LOT thinner than a brick. |
|

They say that light is slowed to "less than 10 centimeters per second." Even if they got it down to 1 cm/s you'd need a path length of 36 m per hour of storage. I suppose you could get long strings of the stuff and wrap it around the house a few times. |
|
| |
If you could make a strand of the stuff long enough that you could coil it up on itself and connect the ends before the photon got all the way through, could you store a photon indefinitely? |
|
| |
It'd probably eventualy hit an imputity or something...by-by photon. |
|
| |
However, the absorption/time is probably better than normal glass, making "my" 9 shaped light -storage weapon more efective. |

[my-nep] your "9" shaped light weapon is no match for my "artist formerly known as Prince" weapon!! |
