Hemp as an energy solution
This was taken from the Journey to Forever Website. If you haven't visited it yet, do it. Do it now!
Invisible farming
Industrial hemp is a high-yielding multi-purpose "fuel and fibre" crop that has great potential for biomass energy. Hemp yields four times as much biomass as a forest can yield. An acre of hemp yields 10 tons of biomass in four months, enough to make 1,000 gallons of methanol fuel, with about 300 lb of oil from the seed (about the same as soy).
Hemp is widely grown in many countries but not in the US, where it's illegal because of a stubborn confusion with the plant's cousin, the drug marijuana. Industrial hemp is the same species of plant but without the drug. In fact hemp contains another chemical (CBD) that actually blocks marijuana's drug effect -- hemp is not only not marijuana, it could be called "anti-marijuana".
The US previously acknowledged the distinction and hemp was widely grown there -- the US State Department still acknowledges the difference internationally. But domestically, growing hemp is banned in the US. In Europe it's subsidised, like oilseed rape and flax. Canada, Russia, Japan, China and dozens of other countries grow large quantities of hemp, while Americans pay $25 million a year for imported hemp fibre and oil products.
Meanwhile an estimated 32 million law-breaking Americans smoke marijuana, probably a lot more than that, and that's not counting Canada. Most of the drug is locally produced, not imported. We've no idea what acreage that represents, but it's obviously a major agricultural industry, and it's invisible. How can you hide a crop for 32 million people? It's produced with no extension agencies, no subsidies, no bureaucrats, no chemical corporations, no marketing boards, no Big Agriculture, and with no apparent use of farming land.
How would the Americans who claim there's not enough land to grow biofuels explain that? Could enough bio-energy for 32 million people also be produced that way, from harmless industrial hemp, tucked away out of view off the agricultural map and nobody even notices it?
Of course it's clandestine and hidden because the US marijuana growers are under pressure from the law, but on the other hand the whole human race is under much more pressure than that to find sustainable answers to its energy problems, and so far we're not being very imaginative about it.
However the illegal drug growers might be managing it, it's obvious that people estimating how much land it will take to grow enough biofuels aren't asking the right sorts of questions.
