To minimize the CO2 emission by traveling around the Earth 16 times a day or the like through the achievement of space flight by zero CO2 exhaust gas since existing aircrafts have extremely large air resistance and a huge CO2 emission amount in a flight in the atmosphere.

In heat production, by taking metal ball liquid gravity cold turbine as core drive + various heat turbine as combined use drive, the atmospheric constant-speed, constant-volume power is set to be almost 10,000-23,000 time mercury power or the like of an existing steam turbine. Air heated by sunlight is compressed by a number of heat pumps to recover the heat of the sunlight-heated air through heating and compression thereof. Overheated steam heat production + compressed air cold production are dividedly reserve the heat to be taken as rotational output of a plurality of turbines. The cost of reaching space through theoretically best rocket jet from the vicinity of the maximum flying altitude is reduced to 1/100 or below in comparison with existing aircraft by driving a combination engine jet part (78B) solar thermal gravitational rotation aircraft (39B) by aiming at injection propulsion to utilize the almost 23,000 time power of an existing steam turbine. A same day trip to anywhere on Earth and travel in outer space are fully achieved through the heyday of space flight by no air resistance.
