caesium! totally fun at pool parties.
[Engadget] Gurus develop way to shrink atomic clock... with lasers

The world's most accurate clocks got even more accurate just a few years back, but now a team from the University of Nevada in Reno is looking to make the atomic clock way, way smaller. Housed at the National Institute of Standards and Technology (NIST) in Boulder, Colorado, these so-called "fountain clocks" send out clouds of caesium atoms through a vacuum chamber in a magnetic field; from there, microwaves in the chamber excite the atoms and then emit light as they drop to a lower hyperfine state. All that rocket science aside, the real point here is that all that magic requires a chassis about the size of a modern day refrigerator. Andrei Derevianko and Kyle Beloy have conjured up the idea of "trapping atoms in place using lasers," which would obviously require far less space for the time telling to happen. Just think -- a chicken in every pot and an atomic clock on every wrist. |

And safe too because you can escape the death and destruction through the hole in the Earth you'd create by putting the cesium in the pool.

Well there much more efficient than wires. Less material being used, so much faster, able to hold more energy, we just have to harness it.

lol...yeah, as long as it isn't your pool or your friends. The only proper everyday use for caesium is fishing.

As for the shrinking with lasers...old news....Wayne Szalinski did this in the 80's. There was a great documentary about him accidentally shrinking his children and then having to find them in his backyard. Brilliant man, that Szalinski.
