Crafty people all over the place are building miniature refractory furnaces in their garage, using the same principles as shown in this video (but on a much smaller scale).
I found this forum posting, which they claim to be able to make diesel fuel for 17 cents per liter using electricity for heat, and maybe cheaper if they can build a liquid fuel heater.

The fungus called Pestalotiopsis microspora can subsist on a diet of polyurethane alone, and do so in an anaerobic environment, according to the researchers who found it. The Yale team isolated the enzyme that enables this fungus to do its work and noted it could be used for bioremediation.
