To increase electric-generating capacity to around 10,000-20,000 times the existing steam turbine by performing power generation employing combinedly metal ball liquid metal gravity solar heat.

Two kinds of power generation performed by opposed metal ball liquid metal gravity cryogenic turbine nucleus geothermal turbines are performed as metal ball liquid metal gravity cryogenic turbine power generation and heat turbine power generation using gravity of material reducing shock of a substance having high specific gravity. Power having the same speed and the same volume as the atmospheric pressure is set to be around 10,000-20,000 times the existing steam turbine power generation. Gravity acceleration is accelerated vertically downward. Thereby, a highest profitability ratio in the world is achieved by operating various kinds of gravity power generation with the number of turbines increased and the electric-generating capacity increased, and the electric-generating capacity in the existing world is decupled by operating various kinds of gravity power generation. Consequently, anybody can cooperatively and easily achieve various automobiles and various ships which are driven by storage batteries, and all-electric homes and electrification of plants driven by electricity by extremely inexpensive gravity power generation, and the global heating is prevented by abolishing the existing thermal power generation in order to reduce fuel cost to zero and to reduce CO2 emissions to zero.
