RE: Imposing a huge taximpose all you want pound for pound nothing burns like hydrocarbon. This stupid green thing is like a professional athlete saying Im gonna eat nothing but but veggies ,great if your 300 lbs overweight but if your burnin 4000 cal /day bring on the triple burgers. There is a huge amount of energy wasted just to run your computer(laws of thermodynamics). So lets all hug a tree ,eat granola and pretend we dont neeed hydrocarbons.
