The original successful fuel for Diesel engines was peanut oil,
after “the free fuel” coal dust kept wearing out engine parts.

All the carbon in peanut oil comes from CO2 that was in the air recently.
Peanut oil is “carbon neutral.”

Many other vegetable oils can do double duty as diesel fuel.

To get EVs like Teslas to be able to complete +300 mile road trips in varying temperature weather,
some one needs to fab up a little diesel generator set
with a very quiet “tuned stub” muffler
that runs on peanut,
or some other vegetable oil.

The gen set and its fuel tank needs to set in a spill proof metal tub that fits the EV trunk floor plan,
and has a latch to hold the trunk lid open a few inches to the air for ventilation.

The gen set power outlet needs to be custom connected to
the EV “regenerative braking electrical circuit”
so that the EV can be charged while driving.

I guess E85 fuel could also be used on gasoline gen sets,
but vegetable oil in grocery stores is more widely available than E85,
and more explosion resistant.
Same with propane.

One would have to declare and pay federal and state road tax on non-traditional vehicle fuel.
By law you have many days to do that paper work.

In line with current slang
these would be “ghost gensets”
