WITRICITY POWERED: WIRELESS TRANSFER OF ENERGY? A WITRIC ONE!

just wondering how energy(electricity), could be transfered wirelessly. the only idea ive come up with is that you could use the photoelectric effect with either efficient lasers or an extremely pinpointed beam of light. the light would hit whatever material creates the strongest current in the circuit possible and you could varry the intensity and wavelength to increase current in the circuit. like for high current you could use intense hard x-rays or gamma rays. can anyone give me and answers as to whether this has been done or whether it could work? also any ideas of other potentially long-distance energy transfers. my idea is to find something that could transfer energy from earth to a satelite/moon/planet or vice versa. im just asking this for the sake to curiosity and because it would be cool to "beam" electricity across the country in the future. :)
btw would this at all be possible to do as a small scale classroom experiment?
we have almost a month after the AP physics exam when we dont need to do anything and this would be cool to say, charge a battery or light a bulb from across the room using lasers :) this would be ranked in coolness just under burning through something with a laser lol.
