Technically Compliant

Did you ever made a conclusion back and forth initiated by tobacco plants back to what kind of plants grew at the point in time when they started to decompose and to build up fossil oils & coal and back again to what kind of plants might be a good idea to grow to get plant oils to drive cars with?

I still wait for the day, when all the car owners that complain to smokers, smoking were bad, snorkeled up all the gaseous and dust outcomes of their cars.
If the car owners survive longer than the smokers, i'll call it a draw.

Diesel engines were designed to be run on straight vegetable oil.

Quasi. But the most interesting part at diesel engines in compare to refined vegetable extra vergile oil engines is, self ignition. Why did Aladin not invent the fuel burning engine, when they had oil lambs already? I think he was more the bag-dad battery guy and busy with an electrical flying carpet or so.

If you aren't familiar with it already, look up "Gasifier" video on YT. Then you can go to the FEMA site and download the blueprint. It is self-igniting without fossil fuel. I'll leave it to you to watch what is used to make the fuel.

Well, that seems to be the same technique as the invented in the 70's for coal, to gain oil from coke.
Here in our region we have a research gate which used such kind of heating in combination with dried and shredded hemp plants.
If one want's to be a bit more professional one can use such an set-up.
The set-up they used automatically shredded and fed dry plant matter (whatever fiber rich plant).

For sure a good idea for development countries and countries with high amount of agriculture.

Sometimes i wonder (quote by Eddy Cochran),
if they know there are companies which build Wood Gas Burning Heating Units industrially.
I promoted such kind of boilers in the year 1998 already.

I wonder because they do not look like they were that poor and they
also have a huge amount of tools, which one needs to build such a Wood Gas Stove.
