The concept of wireless power transmission (WPT) by using a focused power beam of electromagnetic radiation (microwave and laser ranges) is a very promising modern engineering idea for different space and terrestrial applications. As various WPT systems come to be better understood the list of possible applications expands. In particular, a space based orbital WPT system based on a solid-state solar pumped laser can be successful when used as a power supply system for different terrestrial expeditions and as a rescue system in the case of sea and aviation catastrophes. As is known, the existing international monitoring and search system COSPAS-SARSAT makes possible the immediate location of an accident by using a satellite system. Unfortunately, the fast location of people in these situations is not sufficient to save lives because people quickly perish of cold and thirst.

The power supply is one of the most important problems for the perspective spacecraft and vehicles. There are: the traditional spacecraft for phone- and TV communication, ecological monitoring, geological survey etc.; the powerful multiprogram space station (for example “ALPHA”, “MIR” etc.); the transportation vehicles in the near Earth Space (for example for the payload’s delivery from LEO to GEO) with the electric jet propulsion; the prospective station on the Moon and Mars. We have the analogous problems of the wireless power transmission from space to the Earth and from the Earth to space. There are well known projects for powerful space station, which utilizes the solar energy and converts it in a focused electromagnetic beam for transportation to the Earth. The traditional power supply systems of the spacecraft include their own on-board power station (usually by the solar cells or the radioisotope batteries) for each of them.
