As we increasingly look towards biofuels as a way of providing energy without the harmful side effects of fossil fuels(ie global death) there is one biomass which springs to mind that could definitely save us. The only catch is it's illegal! It was once America's number one cash crop before hemp farmers were taxed out of existance and then outlawed. The most useful plant known to humanity was globally banned in the early part of this century to protect fat cats from going bankrupt. Timber barons weren't happy that a new machine called the Decorticator promised hemp paper that was ten times cheaper than timber pulp. Pharmacies who make most of their money from anti-depressants weren't happy either. Not when an easy fast growing weed could do the same job. Please Register or Log in to view the hidden image! The answer? Ban it. How ironic. When grown for seed atleast 70% of the plant's mass becomes seed and each seed contains 50% high quality oil. Hempseed oil was once used to power lanterns. That was before we butchered whales for their oil. So an easy alternative exists which could replace fossil fuels completely but we've banned ourselves from using it. Humans sure are dumb.
