NOVELTY - The engine has a serial metal sphere liquid metal gravity cryogenic turbine used in generating electric power at 26 times than when using geothermal energy at zero carbon dioxide emission. Preservation of a metal sphere liquid metal and the specific large substance impact reduction material is carried by through an increase ball raising apparatus (2F). Compression heat recovery of the cryogenic turbine exhaust gas is carried out using a bite-in all moving blade flywheel turbine (8M) whose diameter is twice the turbine diameter. A geothermal air heater is used in an excavated hole.    USE - Multiple energy conservation cycle combination engine for electric power generation used in driving e.g. floating boat. Uses include but are not limited to a gravity airplane, air suction injection water jet ship, water suction injection ship, solar heat gravity airplane, liquid metal gravity solar heat space shuttle, solar heat gravity rotation airplane, liquid metal gravity solar heat airplane, solar heat gravity helicopter, liquid metal gravity solar heat flight ship, metal sphere water gravity solar heat flight ship, screw ship, liquid metal gravity solar heat ship, space shuttle, space round trip flight ship, flight ship.    ADVANTAGE - The power generation engine generates electric power at approximately 19,000 times of the power generated by the existing steam turbines and 10 times the electric power generated in the existing world. The exhaustion of carbon dioxides is eliminated at 0 fuel cost, preventing global warming and global warming effects such as rise in sea level, typhoons, tornado, monsoon rains, severe local rains as well as drought and postponing extermination of mankind while accelerating the growth of kelps, coral, tangle weed, fish to sustain the food chain.
