Start with a normal home-made charcoal maker (a sealed oil
barrel with a fire underneath and a pipe leading from the top
to the fire).
Then stick in a home-made jet turbine (basically a car
turbocharger) to run off the gases and power a generator.
Then put a catalytic converter in the exhaust
to clean them
up. Use the cat and remaining exhaust temp to heat up the
bottom of the barrel.
