Prof. Kohama has experienced "Japan 2011 earthquake/tsunami disaster". He saw real disaster scenes with his own eyes. Power outage occurred. In the situation, time is critical, but victims could not know tsunami/earthquake information. This partly led to expansion of the damages. The following crossed his mind: If electric power supply could be continued for several days, the damage expansion would be minimized. Victims could get moment-to-moment changing disaster conditions from broadcasts. Airconditioners, if operable, would help patients and sick persons keep their health conditions good. This would spur him on to accelerate his MgFC development having thus far been made, I suppose. For an example of MgFC use, see the picture in previous article. More
