euthenize,
render to extract lipids.
Heat lipids with NaOH (catalyst) and 3x methanol (toxic corrosive industrial chemical but
not as bad as politicians). Then, separate (centrifuge, sep funnel, etc) the cracked lipids, now Me topped chains.
Will run a vehicle. Much better than hot air, or blood.
And, there are plenty of fat politicians needing rendering.
