I my self made a 3KW 11GHz transmitter with a beam antenna using a quilostron. The transmitting range was enormouse, almost 10Km but only as a beam. Imagine something like a microwave oven... At 100 meter distance I used the same kind of antenna and quilostron for receiver and the captured energy was aroung 1.2 KW but with a 11GHz frequecy so I needed to make it DC (discontinous current).

Please allow me to add something... Wireless energy transfer or wireless power transmission is the process that takes place in any system where electrical energy is transmitted from a power source to an electrical load, without interconnecting wires. Wireless transmission is ideal in cases where instantaneous or continuous energy transfer is needed, but interconnecting wires are inconvenient, hazardous, or impossible. Though the physics of both are related, this is distinct from wireless transmission for the purpose of transferring information (such as radio), where the percentage of the power that is received is only important if it becomes too low to successfully recover the signal. With wireless energy transfer, the efficiency is a more critical parameter and this creates important differences in these technologies. Very, very interesting stuff.
