Nuclear fusion became popular by the cold fusion fever since last March. The whole aspect of the traditional 'hot' fusion research is outlined in this article because the hope of a easy, cheap fusion power has faded away, unfortunately. The first part describes the principle and basic merits of fusion power. One of the points is that there is almost no possibility of radioactive materials being scattered to the environment even though the fusion reactor has a non-negligible amount of radioactives, because the fusion reaction can be stopped simply by cutting the fuel gas supply. Fusion reactor is a very safe system.
Fusion reactor will hopefully be utilized in the first half of the next century.It can provide energy to mankind for more than hundreds of million years. And the research of the fusion reactor gives motivation to the development of many high technologies.
Particularly for Japan, fusion reactor is just fit to our situation, and moreover, considering the economic situation in the world, we have to use our resources for the development of new energy sources and contribute to the future of all of the mankind on the globe.
