It’s past five, so I guess I can get this in early.  Seen at Uncle’s place:
Get a diesel. Then use biodiesel.
1 metric ton of dead hippies can be converted to 80 gallons of biodiesel via heat depolymerization.
Formerly annoying dead hippies are a nearly inexhaustable resource … and if we did exhaust them, people would cheer regardless.
And the hipiies carbon foot print goes to near zero once they stop breathing.
A win win scenario for all.
I don’t generally support growing fuel at the expense of food production, but this is one type of biofuel I can get behind!
