Abstract:Space solar power shows great promise for future energy sources worldwide. Most central power stations operate with power capacity of 1000 MW or greater. Due to launch size limitations and specific power of current, rigid solar arrays, the largest solar arrays that have flown in space are around 50 kW. Thin-film arrays offer the promise of much higher specific power and deployment of array sizes up to several MW with current launch vehicles. An approach to early commercial applications is for space solar power to distribute power to charge hand-held, mobile battery systems by wireless power transmission from thin-film solar arrays in quasi-stationary orbits will be presented. Four key elements to this prototype will be discussed: (1) Space and near-space testing of prototype wireless power transmission (WPT) laser and microwave components including WPT space to space and WPT space to near-space HAA transmission demonstrations; (2) Distributed power source for recharging hand-held batteries by wireless power transmission from MW space solar power systems; (3) Use of Quasi-Geostationary satellites to generate electricity and distribute it to targeted areas; and (4) Architecture and technology for Ultra-lightweight thin-film solar arrays with specific energy exceeding 1 kW/kg. This approach would yield flight demonstration of space solar power and wireless power transmission of 1.2 MW. This prototype system will be described, and a Roadmap will be presented that will lead to still higher power levels.
