I would like to ask if there is any Nuclear process which can be used to produce a wireless power ?

Is there any nuclear process can be radiate to the environment with no harm to human beings?


How can I use the photo electric effect with some high Intensity radiation ?

Neutrinos are pretty harmless, i guess... –  Asphir Dom Feb 27 '13 at 10:31
    
@AsphirDom but interact so weakly that they are useless as a power source. –  anna v Feb 28 '13 at 5:28

Try sending hydrogen through mail. See en.wikipedia.org/wiki/Sneakernet (mailing of digital information). In case you're interested there's background radiation en.wikipedia.org/wiki/Background_radiation –  raindrop Feb 28 '13 at 6:40
    
@Raindrop can you write it as an answer? –  0x90 Feb 28 '13 at 6:57

Are you thinking of a nuclear powered electric generator or the electromagnetic pulse from fission as a source? If it's the former then it's known as Wifi.

There are no nuclear processes that can be used directly to transmit power. With any nuclear system the power is first removed from the reactor as heat. This heat is then used to drive a turbine which in turn drives a generator. This way, part of the power (less than 30%) from the nuclear process is converted into electricity, which is then transmitted to the users. The rest of the power is waste heat.

Because of the conversion from nuclear to heat to electricity, we end up using only those transmission systems that are economical for electricity. Unfortunately, wireless transmission is not practical with present technology, and will never be practical for direct transmission to end users. It may become practical for transmission of large amounts of power in a narrow beam - especially from space to earth.

Any radiation that directly escapes the nuclear reactor, without being converted to heat, is potentially dangerous, as it consists of high energy particles or radiation. With fission reactors most of the danger comes from the long lasting fission products. Fusion reactors generate copious neutrons which are dangerous if not absorbed, and can also make the reactor vessel radioactive. However, the total radiation from a fusion reactor is far lower than from a fission reactor.
