Laser Power Transmission as a Terrestrial Expedition Power Supply Under Normal Conditions and as a Rescue System in Case of an Emergency

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. It is apparent that the chance to save people after sea and aviation crashes may be substantially increased with prompt and reliable power supply to the site of the catastrophe. The analysis of possible technical parameters of such an orbital laser WPT systems is presented in this paper.
