Historically Hemp (Cannabis Sativa L.) has been a very high yielding plant (Haney 1975). Assuming that hemp produces up to 4 tons/acre seed plus 10 tons/acre stalks, Table 1 shows how many gallons of liquid fuel import could be saved by each of the following proven biomass fuel conversion routes.
Table 1. Conversion technologies for hemp stalks and hemp oil
CONVERSION CONVERSION GASOLINE EQUIV TECHNOLOGY EFF - % GAL/ACRE
1 Ethanol from fermentation of hydrolyzed cellulose 20 200 2 Digestion of whole stalks to methane 50 500 3 Producer gas from thermal gasification of stalks 85 1000 4 Methanol from syngas from gasification of stalks 65 750 5 Methanol from pyrolysis of stalks 3 30
OIL SEEDS - 4 tons/acre
6 Hemp Seed oil from Seeds, no conversion 100 300 7 Biobioesel premium diesel fuel from hemp seed 90 270 oil combined chemically with methanol
You're going to seriously claim that 1 gallon of hemp oil is equivalent to 3 gallons of gasoline? I don't think so. I've seen hemp burn and it don't burn anywhere near that efficiently.
No, he is saying you get the energy equiv. of 300 gallons of gas from 4 tons of seed, PLUS the other stuff from the stalks. I can't speak for the veracity of the numbers, but that would be my interpretation. Also, he is talking when processed into fuel oil/gas, not put in a pipe and... Never mind. petro@playboy.com----for work related issues. I don't speak for Playboy. petro@bounty.org-----for everthing else. They wouldn't like that. They REALLY Economic speech IS political speech. wouldn't like that.
