高強度のマイクロ波照射下でハイドレート構造を分解するための予備実験を行った。純水とメタンを成分とする,液体窒素温度(-196℃)のメタンハイドレート(MH)に対し500 Wのマイクロ波を10秒間照射したところ,質量低下を示した。 これはMHが分解され,メタンが開放されたことによる質量低下である。MHを熱分解するには-76℃まで昇温させる必要があるが,実験では-196~-180℃の間で分解が起こった。これはマイクロ波の「仕事」による分解であると考える。

&nbsp;&nbsp;The respective awareness of the Intergovernmental Panel on Climate Change (IPCC), the Japanese government, media and citizens about the change of sea level at some future date due to climate change was surveyed and analyzed. Three official reports from the IPCC, the white paper on the Quality of the Environment in Japan from the government, the articles in the Asahi Shimbun newspaper from about the past 20 years, and the questionnaires by the Japanese and local governments conducted towards citizens were used. The results of this investigation were that the IPCC concluded in their past three reports that the sea level was estimated to be lower because of ice in the polar regions due to climate change, the Japanese government did not describe this point clearly, the newspaper drew the opposite conclusion from the IPCC and the understanding of citizens was that the change in climate caused the sea level to rise. These differences were due to the lack of or misunderstanding of scientific knowledge such as Archimedes's Principle and the migration of fluid materials, and to the psychological trend of human beings. It is necessary for the government and media to clearly explain and announce these scientific facts in a modern society which maintains a close relationship to science.<br>

The amount of woody biomass resources in Aichi Prefecture and Toyone Village was estimated on the basis of theoretical and actual production efficiencies. Five factors should be considered at the steady production of reduced carbon from carbon dioxide by sunlight in woods. The ratio of leaf to forest area, the reflection of sunlight on leaf surface, the conversion efficiency from the light energy, efficiency of optical system, and of dark reaction are 0.70, 0.82, 0.24, 0.31, and 0.92 respectively. On the other hand, four factors are in the timber production stage. The energy consumption loss for the daily life of woods, the waste at the forest, the thinner woods to main cutting production, and the thinning are 0.50, 0.47, 0.435, 0.44, respectively. The total efficiency was calculated and the result was 0.0023. Furthermore, near fiscal year 2000, primary energy consumption in Aichi Prefecture is 1.48×10^9 GJ/year, so it is 2200 times than the present production amount and 300 times the best theoretical production amount.
