SOLAR THERMAL ENERGY STORAGE SYSTEM

Akiyama, 2000). Although encouraging results have been obtained from the experiments, it is urgent to design a whole removal system compact enough for vehicle application. Two methods for storing energy are employed in high-power pulse generators: capacitive and inductive storages. Whe[r]
