Farming 6% of the continental U.S. acreage with biomass crops would provide all of America's energy needs.
Hemp is Earth's number-one biomass resource; it is capable of producing 10 tons per acre in four months.
Biomass can be converted to methane, methanol, or gasoline at a cost comparable to petroleum, and hemp is much better for the environment. Pyrolysis (charcoalizing), or biochemical composting are two methods of turning hemp into fuel.
Hemp can produce 10 times more methanol than corn. Hemp fuel burns clean. The use of hemp fuel does not contribute to global warming.
