Hydrogen gas is manufactured by the hydrothermal reaction of calcination dolomite and aluminum in Kimoto's patent. The authors obtained an important hint from his patent and conducted the following experiment. There were prepared aluminum sample of 5g, 5g of calcium hydroxide sample,which is the main ingredients of calcination dolomite, and 10g of mixture sample of them and the experiment was conducted over three weeks in atmosphere. As a result of measuring weight at every three days interval, the weight increase was hardly observed in the alumin sample. About 0.2g of the weight increase was observed in the calcium hydroxide sample due to the molecule conversion, in which calcium hydroxide and carbon dioxide in the atmosphere reacted and calcium carbonate and water were generated. However about 1.0g of weight increase which is 5 times larger than calcium hydroxide sample was observed in the mixture sample. It was found from compound analysis by the XRD method and elemental analysis by the EDX method that 0.8g of weigh difference that was calculated by subtracting 0.2g from 1.0g was brought about by the atomic conversion and succeeding molecular conversion where about 13% of aluminum was converted to calcium and further to calcium hydroxide. And this weight difference was confirmed to depend on the average humidity in three kinds of experimental results carrying out by changing years and months. And it showed that the atomic conversion mechanism might be able to be scientifically explained by the quantized water theory advocated by Takao and others.
