The structure of the geothermal equipment is actually very simple. Despite having been destroyed by the electromagnetic pulse and submerged by the flood, they were rebuilt by some handcraft professionals organized by the government officials after the flood subsided.
Although they're not as compact as those manufactured before the disaster with the aid of lathes, their function isn't affected at all.
To supply all the Refuges Centers in the city area with geothermal devices, the Officials specially built an underground power plant. Most of the time, it generates electricity on a small scale, not only to ensure the normal operation of the power plant but also to ensure the operation of the underground plantation and breeding areas.
