    I assume you mean Giga and Mega and not milli and what ever g is.

    24GWh for 10 billion .9GWh for .8 billion

    10 / .8 = 12.5

    Works out at about
    11.25GWh for 10 billion.

    Now Nuclear plants will not have a demand during the night so not all of the 24GWh will be used. (say 6 hours of no demand) so works out about 18GWh of usable power.

    Probably the same assumption you are making where the nuclear plant is going to have customers willing to buy the power all the time.

    It is not just wind turbine that produce the power but also the nuclear plants they can't turn off.

    If there was a free market, no one (outside of Brazil) would grow plants for fuel-ethanol. It's just too expensive at the moment.

    Australia has a large sugar ethanol production as well.
    Of course no one would produce corn ethanol is my opinion.

    In 2008, total worldwide energy consumption was 474 exajoules (474×1018 J=132,000 TWh). This is equivalent to an average power use of 15 terawatts (1.504×1013 W)

    According to http://www.emcore.com/space-photovoltaics/space-solar-cells/

    135.3 mW/cm^2
      84 mg/cm^2

    1.61W/kg

    Cost of space elevator
    http://en.wikipedia.org/wiki/Space_elevator_economics#Cost_estimates_for_a_space_elevator

    $220/kg up into space

    $136.65 per watt in space.

    http://en.wikipedia.org/wiki/Price_per_watt

    $4-5 for solar. * 6 (4 hours of production so need 6) = $24-30
    $8 for wind * 5 (20% production) = $40

    Battery

    1 watt for 48 hours / .3 Depth of Dischage = .16Kwh * $200 = $32

    $96 total

    According to a pdf i found.

    500 kV double circuit transmission line
    (Capacity per circuit 2500 MVA-3500 MVA)
    $1.8M per km

    or roughly $1 / 1300Km for power lines to transmit 1 watt. .018 / watt for the transforms * 11 for each bit of solar and wind being spread out = .2

    ----
    FINAL CONCLUSION
    ----

    So for less them the cost of just getting a single watt panel into space on a space elevator:
    6 watts of solar (about 24 watts/day)
    5 watts of wind (about 24 watts/day)
    2 days of storage at 1 watt/hour
    spread out over 1300Km

    They sense the grid by changing the supply slightly.

    If that triggers a large change in voltage they realize that the 'grid' they connect to is small and then shut down.

  21. Re:Send it into space! on Solar Panel Breaks "Third of a Sun" Efficiency Barrier · · Score: 1

    Honestly, it'd probably be much easier just making a HUGE ass magnifying glass in space that sends it to a solar panel in space, then beam it back down to surface in the most efficient non-interacting beam. (or deadly high energy beam and just put up a no-fly zone)

    The problem would be cooling because space is inert, you'd need to have a huge cooling station behind it that is kept in constant shadow to dissipate heat quick enough for such a huge industrial-scale design like that.

    But, it is entirely doable with the right funding and people behind it.
    There are a few space solar projects going right now. Varying distances along their project timeline.
    There is still time for us to be space truckers. Soon. Soon.

    You need to keep the magnification on the panels, that means the cooling is always in shadow as a result. Still a large structure though.
