Geothermal Plant
Kazumi the owner of Baba Meeting Area has built a geothermal power plant. Taking this occasion I tried to study about geothermal energy.

I think everybody knows that the geothermal plant is to generate electricity through a turbine using steam from underground. A question is why it has not been used widely in Japan that has many volcanos. The three structures at the central position are production wells where the steam comes up. The large building behind is a cooling tower through which most of the heat from underground (80%?) will be ejected into the air.
Generating turbine. In order to operate it, not only the high temperature source but also the lower temperature is required to drive the steam. A system to eject the steam into the air is called back pressure type and the one using cooling tower is called condenser type. In Japan the latter is mainly used.
The control room. I imagined that of a rocket control but it is simpler than I thought.
There are many pictures of control room on the Web. There are more sophisticated ones. Are they old?
Along the way, this is the one for nuclear plant. Not all of them are cool as an old airplane cockpit.
As a result of my brief study, I understood that the geothermal plant cannot be the ultimate answer. Although Japan has many volcanos, whole usable geothermal energy can manage only 10% of the needed electricity, and also there are several real problems. The only way might be to keep making steady efforts. Stick to it Kazumi!
