I have to say, the very top picture in the article does look a little like a flux capacitor…
Quoting the Slashdot quote:
“Frybrid has realized the dream of Dr. Emmet Brown's Delorean: putting garbage directly into your vehicle, and have it be turned into directly into fuel. This past fall, Frybrid installed a system into a 40' luxury RV that sucked up waste vegetable oil from the back of restaurants, removed the water and filtered it, and then burned the dry and cleaned vegetable oil as fuel. The family drove their converted RV from Seattle to Rhode Island on $47 worth of diesel fuel. Plans are underway for a smaller version of the system to fit in the bed of a pickup truck.”
