Under investigation is a system for heating and adding moisture to air in ascending atmospheric wind current power generation at a level of several hundred million kW using an artificial structure constructed on a desert plain in a subtropical region or on an ocean. In power generation on a subtropical desert plain, the area required for collecting solar heat will increase in proportion to desired output; however, the conveyance of a huge amount of heat poses a serious problem. It would be rather more advantageous in view of the energy balance sheet to use a system that moves the structure within the area in which the solar heat is being collected, and this would also be a much simpler system. In a wind power generation system constructed on the ocean, it is possible to move the structure over a wider range, thereby allowing power generation in more favorable meteorological conditions. This system is thus expected to obtain a sufficiently large output even using humid air at the same temperature as that of surface sea water. It is therefore possible to utilize ocean surface water as a natural source of heat to construct a system which does not require an artificial solar heat collector covering a huge area that might exert an adverse effect on ocean ecosystems.
