To provide a water collection feed system for moisture in atmosphere using natural energy having a dissolving means of water shortage of an area or the like where island parts or deserts advance by mitigating temperature warming or concentrated heavy rain by collecting moisture in the atmosphere.

Water vapor in the atmosphere is collected/fed as dew condensed water by attaching an electronic circuit due to a thermo-electric conversion element to a balloon by using buoyancy by filling the balloon with lighter gas than air such as He gas. In addition, even droplets floating in the atmosphere are collected/fed by using a rotating blade.
