If they can pull off small scale units for farms that can go straight to biodiesel for farm equipment they might have a chance, but how many farms are going to buy $100,000 of machine to make their own biodiesel. It would need to be a regional farm co-op I think, as I don't think any single farm could justify it, but I am not a farmer, so I don't know. I need to look at gallons per acre numbers again, my last thought was it was going to require transport to refineries for the fuel applications (another cost). No doubt remote use of desert land sounds interesting, but it would need to be near the equator to avoid winter heat issues. He did say heating would be needed for outdoor northern locations!
