Coming back to hemp should be the good idea. Oil and wood have replaced Hemp (for

maize and wheat, since a very long time. The idea that it is something dangerous is a
total complete recent construct, and has only been a Trojan horse for bandits
(probably the one losing the job after the end of alcohol prohibition) to get power.
Hi,
Any idea how much land would be required to grow sufficient hemp to supply the
millions of barrels that our civilization requires? How much fertilizer? How much
labor? Have you seem the quantity of energy that is required to turn corn into fuel.
for example? The problem is that hemp and other biomass fuel idea are simply too
expensive in terms of energy and man hours to replace petrofuels.

Oh! If wiki says so ...
Note that I did not say that only hemp is needed, nor did I condemn entirely oil and
coke. I am a realist. But Ford did the calculus, and for a very long time, if hemp would
have just be continued to be used, their would have been a drastic harm reduction,
possibly ecological.
There certainly would have been a drastic reduction in industrialization. Ford also
considered making car bodies out of soybeans, but that didn't work out either.
Between possibly bad and certainly worst, we have to choose the possibly bad, but we
know that unscrupulous special interest made the decisions, and that is the problem.
I don't see anything 'unscrupulous' about deciding to exploit the energy embodied in coal
and oil. It has been a major factor in creating the modern world. It has created some
problems as side effects, but ones that can be solved.

Well the real problem is that we tolerate that and that most people buy the media talk
without thinking, the real problem is the "boss is right" routine implemented in many
mammals. Our brain evolves less quickly that our ideas and technology.
