What about the metal process plants that zap the power grid with big draws at night?
This reminds me of the Biodiesel craze around these parts. They claim how great it is to take the excess cooking oils and such . . . until that relatively small suppy dries up. Turf-wars and politics over who gets the used fried fish oil market, and who gets to control the Micky-Dee's big dump.
By 2012 we will all be in flying cars running on hybrid biodiesels from shade grown fair trade corn oil. --that's the utopia, right?!?!
