Some thoughts about the hydrogen civilization and the culture development

Civilization is defined as an aggregate achievement of inventions for realizing lofty human ideas, and culture is defined as the intellectual side. The realization of human ideas is the sustainable development (SD), and one of these pillars is the energy system. The main current of the human energy carriers has made the transition from coal to petroleum, and from petroleum to natural gas. This trend means the transition from the fuels with a larger ratio of carbon to those with a larger ratio of hydrogen. Ultimately, the main energy current will be converged to hydrogen. The hydrogen civilization is about to emerge today. The centripetal force acting upon every fuel toward hydrogen has an intellectual analogy to Brownian motion, which is one of the main topics of the concerned complexity science. Moreover, Ashbyʹs requisite variety law indicates that the civilization must wear the cloth of the culture in order to build up the endlessly sustainable civilization.
