We research the reaction of zinc oxide with a view to the sustainable generation of hydrogen energy. We have made it to reduce zinc oxide by extracting it heat required for the reduction reaction from sunlight. We used an electric furnace to investigate the relationship between zinc oxide and heat. Because it was difficult to adjust the heating temperature of zinc oxide with sunlight. As a result, we found that the reduction amount reached 1.00g. i.e. I think the reduction rate became 100%. But the reduction amount was 0.01g with sunlight. This is the task. I have been implementing new equipment to increase the reduction amount.
