Outline of Final Research Achievements

Renewable energies, RE such as solar light needs to be fully utilized in convenient, efficient and environmentally benign manner in order to realize a sustainable and conflict free society. Hindrance of substantial use of REs is its maldistribution both in time and space and thus some kind of leveling technology system is crucial. One solution is to pack solar energy into “fuel”.
This investigation has been devoted for developing a key technology of recycling the solar fuel in the form of metallic magnesium through a reducing process of magnesium oxide, MgO. In the process, solar power is converted to laser radiation only which can reduce MgO with using no additional chemicals and resulting in an efficient energy system.
Combination of experimental and theoretical investigations showed the possibility of reducing MgO with a high efficiency and the feasibility of energy recharging technology.
