Self-sustaining

It seems that Elon Musk is wondering why the Japanese are not firing rockets into space as crazily, and as frequently, as his SpaceX. My guess is that the Japanese are waiting for better technology, waiting until there is a better time (maybe now is too early), waiting for lower costs, or waiting for a big war (inevitable for some) that would shake global politics and destroy the status quo. There are proponents of teleportation, as Michio Kaku, a Japanese-American physicist, futurologist, and writer. The Japanese do not have the same "now, now, now" culture as the Americans. Their "now" culture comes from the mindfulness of the present moment, Zen, unlike American. Many Japanese like also futurology, which has become a religion on its own, there. Elon Musk and others may think that safe teleportation may be a long, long time from now, if ever. In the interim period until such technology would arise, sophisticated rockets may be the only way to get to another planet. Elon Musk has been correct many times, judging from his material and financial successes. (He has admitted that maybe a self-sustaining society on Mars and a "multiplanetary" human civilization would probably arise after his own lifetime.) Americans like "brute force," but maybe it is not the Japanese way. The Japanese have a much longer view of time than do the Americans. They believe in spirits everywhere in nature (Animism) that Americans maybe do not sense.

There was nothing odd, or futuristic, or exotically “eco” about the house — no solar panels to be seen, no giant arrays of thermopane windows passively drinking up light and heat; yet here, I’d been told, in the Sourland Mountains in New Jersey, an hour from Manhattan, was a house that had the potential — not long from now, not 20 years from now, but maybe within 5 to 10 years — to help turn millions of American homes into fully self-sustaining power plants, each one capable of producing hydrogen to fuel cars as well.
