For affluent and healthy life for all people in the whole world, energy production, environment conservation and other related subjects have been studied.
I. Global carbon dioxide recycling
Global carbon dioxide recycling consists of power generation by solar cell in the deserts, hydrogen production by seawater electrolysis and methane production by the reaction of carbon dioxide with hydrogen at the nearby desert coasts, and methane combustion and carbon dioxide recovery at the energy consuming districts. The elemental systems which have not yet been industrialized are seawater electrolysis and carbon dioxide methanation. Their key materials and systems have been studied.
