Space-based Power Generation

  1. will we be reading this again 25 years from now by hagbard5235 · · Score: 3, Insightful

    This was first seriously proposed by
    Gerald K. Oneill of Princeton University in
    1975! It was feasable ( and even profitable )
    then, but the capitalization was to high for
    any organization on earth but the US Government
    to undertake. The only reason we haven't done
    it already is because of a defect of will, a
    myopy of purpose, and inability to look further
    ahead than the next election.

    When will we, the citizens of the United States,
    have the vision to demand these sorts of
    projects from our government? Oneill's initial
    proposal had an estimated 20 year pay back time, for
    the first powersat. Subsequent powersats would
    have been much cheaper. If the proposal Oneill
    made had been taken up seriously in 1976, and taken
    say 2 years to get it's political legs so that
    actual work began in 1978, and it took ten
    years to build, we would have had cheap abundant
    energy by 1988.

    Given cheap abundant energy it would be feasible to
    produce, for example, metal hydride or fuel cell
    powered cars. Given a 10 year ramp up and phase in
    for those technologies we would have in 1998
    been largely petroleum free ( at least for
    power ).

    Does anyone question that this would be a better
    place to be... and we could be there by now, if
    only we had the vision, and the will.
