To attain power generation capacity by metal ball mercury gravity solar power generation which is 23,000 times or the like greater than by an existing steam turbine.

In opposed metal ball mercury gravity solar power generation, three kinds of opposed metal ball mercury gravity turbines are driven respectively by vacuum acceleration+overheated steam acceleration+compressed air acceleration of metal balls and mercury to increase the power generated by the turbine drive with an atmospheric constant-speed, constant-volume power 23,000 times or the like that of the existing steam turbine and an increased drop of 10-1,000 m or the like as vertically downward gravity acceleration. The operation of the serial metal ball mercury gravity solar power generation allows to anybody to easily cooperate with spread of various automobiles or various ships driven by inexpensive metal ball mercury gravity solar power generation storage batteries, spread of all-electric homes and electrification of plants driven by electricity, and the like. Consequently, zero fuel cost, zero CO2 emission, zero temperature rise of seawater, and increased growth of seaweed, coral and fishes by hastened natural phenomena are attained, whereby the existing thermal and nuclear power generation is reduced to zero to prevent the global heating.
