Comment on What is hemp? by Roderick Oates.
The original fuel for which the diesel engine was invented was Hemp oil. This you should verify by reading up on the engines development. It may also be of interest to consider the exhaust content of an engine running on Hemp oil. Perhaps the engine would be responsible for the wellbeing of the people rather than caused them harm.

What is hemp?
Not change, we used to use Hemp for a very wide variety of things. Sailing ships carried hemp sails, hemp ropes, for sealing the wood joints, corking. When finished with the sails were used for jeans. A pair was found in the past and the team which found them tried to ruin them by washing and wearing. They failed in this effort.
