Use neutrinos for communication?

[Jack Bauer]

Could we somehow develope a neutrino telephone? Since they pass through everything, you wouldn't have to deal with obstructions like buildings which are often an issue with cell phones.

If they can pass through building and even the Earth that easily, what makes you think it will interact more easily with a "telephone" to produce a signal? Just look at how big and tedious the Auger Observatory is currently in trying to detect neutrinos.

And on the other end, how would the sender create a strong neutrino signal without incidentally irradiating himself with gamma rays?

get lead pants and turn your hand held nuclear reactor off and on quickly and you have binary, then bury your phone underground to try to receive the signal...

if we can use neutrinos to send signals we can send messages back in time can't we?
