An energy cycle using solar power and metals has been proposed. High repetitive laser pulses are generated by a solar-pumped laser or a laser generated using solar power, and the laser pulses are irradiated to metal oxides in liquid. We can obtain reduced metal nanoparticles with this method, and solar power is effectively stored as chemical energy. We fabricated Li air fuel cells using sintered Iron or Aluminum nanopaste plates as negative electrodes. Electricity was successfully produced from these cells. The observed maximum output voltage of the Al paste Li air cell was 2.9 V when they were connected to a low load. The Fe or Al paste Li air cells are expected to become common power supplies with high-energy density and high output power.
