You’re right and he’s not the only performer who does.
I don’t remember whether there are any currently up and running, but he also plans to set up a whole network of Biodiesel stations beginning in Texas.
Obviously Biodiesel is easier to use because you don’t need to install a warming element the way you do for WVO.
As a matter of fact, Mike Rowe profiled a guy who does how own chemical conversion to Biodiesel on his previous show, Dirty Jobs.
I’m just not that much of a chemist or I’d be running on Biodiesel :)
But obviously the big oil companies have a vested interest in preventing the govt. from backing any efforts similar to Willie. If that were not hue case, we’d have made much greater strides (similar to Brazil which plants huge fields of switchgrass to convert to Biodiesel).
There’s not much good reason for the US to not do likewise, or just convert all that fryer grease which businesses now pay another company to remove.
And all this gum-flapping about cheap sources of renewable energy is just a bunch of noise to disguise the fact that it already exists.
After all, when Rudolph Diesel developed his first engine and demoed it at the World’s Fair, what was he using for fuel ? Vegetable oil, of course. Not WVO, but vegetable oil all the same.
But big oil prefers to keep that salient fact buried in the murky past ;)
