And how many humans hand-cranking windmills for how many fortnights would that be?

  Let me see. With a hand-crank you could get about 25 watts, so... given all six billion humans you could generate that much energy in... uhh, 5.2 * 10^27 fortnights. Any other units which might be clearer?

    I prefer to measure power in poundal-furlongs per lunar year.

      Oh, sorry. With a hand-crank you could get about 63.108 poundal-furlongs per lunar year, so... given all six billion humans you could generate that much energy in... uhh, 5.2 * 10^27 fortnights.
