I suspect for aviation diesel will be the solution for a while.

Exactly. Leaving 100LL for unleaded is half-assed. When fuel prices
match the prices in Europe, consumers will be going straight to
diesel, and Jet A will supply them.

I also agree w/ M. Aircraft makers are short-sighted. Consider the
small fraction of single engine diesels available. More manufacturers
should have already been on that by now.

Out of curiosity, what's to stop the GA pilot (in terms of FAA law)
from making their own batch of biodiesel from waste oil to get rock
bottom prices, and sidestep the avgas tax entirely?

Accounting for the cost of raw material, the yield would be ~$1/gal,
which would make the fuel costs of flying cheaper than that of driving
a typical car. And (IRS aside) what kind of FAA approval process
would enable a GA pilot to do that? Or is that scenario pure fiction?
