Dr. Thomas H. Culhane, professor of sustainability at the Patel College at USF is now running this Israel HimeBiogas unit for student demonstrations, connected to a backyard barbecue. It was innoculated with RidX and other commercial septic powders from Home Depot (4 boxes) and took five weeks to start making gas. It is fed on grass clippings and food waste.
