I have read a few studies on alcohol fuel production, and none of the facilities studied have been a net-producer of energy. While the idea is an intriguing one, energy production is difficult. Has Blume actually shown an ability to produce fuel?

Note: I've always been a fan of using seaside solar-powered electrolysis to produce hydrogen fuel, though hydrogen storage has its own issues.

Yes, Blume has produced fuel. If I recall correctly at one point he had a number of people with fuel conversions on their vehicles who were buying his gas through a kind of CSA (Community-Supported Agriculture) business. He's very practically oriented.

Part of what shifts the economics here is that the leftover byproducts of both fermentation and distillation are returned as inputs to the farm.

I also have to mention, at one point Blume had a contract with a donut bakery to collect and make fuel from all their old scrap dough. Sugar and carbs...
