This may seem like a chicken$#it fuel alternative, but it's beginning to produce results. From Treehugger.com and other sources:
You can't stop progress: turning chicken droppings into electricity is one thing, but developing transportable pyrolysis units to convert poultry droppings into bio-oil on-the-go? A team of scientists from Virginia Tech's College of Agriculture and Life Sciences is working with a coalition of poultry growers to test a transportable unit that would convert poultry litter — a mixture of manure, feathers, bedding and spilled feed — into bio-oil (or pyrodiesel), producer gas and fertilizer.
It would do so by first heating the litter until it vaporized; the vapor would then be condensed to make the bio-oil. At the same time, a form of slow release fertilizer could be recovered from the pyrolysis unit.
If more immediate results, there's always this.
