That seems like a pretty ambitious business model. Personally, I question the viability of it. As a commodity yellow grease is trading at the equivalent of over $2/gal. They will have to collect it, treat it, store it, and dispense it. Maybe their planning to make their money on the conversion set ups?

I think Flainn was alluding to the fact that SVO as a fuel has already taken off. It's been a popular alternative fuel for over a decade now, ever since oil trading was deregulated in the late '90's and $1/gallon fuel was no more. There will always be an interest amongst serious 'hobbyists', and environmental types, but I doubt it will create much of an impact in the diesel world. There's just not enough vegetable oil around to do that. I'm curious to see how long they can make it.
