Please provide Information on the capability of a wireless energy transfer including the distance, power, and list of methods available and possible methods in future
There is a whole spectrum of possibilities for wireless transfer of power, it basically takes a transmitter and a tuned receiver. But nearly all of these technologies are limited to line of sight. Tesla was fond of over the horizen ground conduction of extremely high voltages, but that technology has some 'ground' safety issues. The other way to get over the horizen is with RF in a frequency range that bounces in the atmosphere, but it would be very lossy and likely interfere with radio users. From outside the atmosphere though line of sight is fine. From space you can use mirrors to concentrate solar light and aim at solar facilities during the night, making solar panels and solar concentrater power plants work at night.
