    Returning to pre-industrial technologies is no option for the future unless there is a massive and sudden destruction of the biosphere. So industry, transportation, healthcare, entertainment and food production will have to continue using modern technology. Some technologies obviously need to be improved to make them more selective, more affordable, and more recyclable. In the beginning those technologies will be inefficient, expensive and unreliable. But someone needs to buy them so that development and improvement can continue. I see plenty of comments to the effect: "This technology is immature and will never be any better, so all effort is wasted." Bill Gates said something like that about the WWW. Tesla's professor said it about AC electric motors.

    Being an early adaptor is for the few and rich. We others can do something for improving the political and economic climate for new developments.

    there's a remarkable gravity powered free energy machine that our spaceship keeps revolving around.

    people are remarkably stupid and stubborn, especially the "smart" ones.

    nuclear fusion is going on right now. 8 or so light minutes away.

    but nooooo it's not 100% efficient, so there must be a better way ( since when has 100% efficiency been achieved in energy transfer, ever? formula one engines just broke 50% this past year.)

    so they try to make fusion in a torus, rather than utilize the free fusion going on above them.

    fortunately there's probably a few hundred million years to go on the free gravity energy round the solar system.

    unfortunately there's no time left to cease the destruction of wilderness habitat by humans due to overpopulation.

come again
