An inquiry has been ordered against a US surgeon who used fat from the clients to run car. The authorities are investigating the claim by the Beverly Hills Cosmetic surgeon, Craig Alan Bittner. According to the surgeon, he used the fat removed from his patients during liposuction to propel his car.

Any type of fat, animal or vegetable, can be turned into biodiesel. But it is unclear when Dr. Bittner began converting fat extracted during liposuction to fuel and why he ended the practice. The doctor was in news after several of his patients filed lawsuits alleging he allowed his assistant and girlfriend to perform surgeries without a medical license. Mr

Bittner wrote on his website: "The vast majority of my patients request that I use their fat for fuel - and I have more fat than I can use.

"Not only do they get to lose their love handles or chubby belly, but they get to take part in saving the Earth."

The doctor also claims to have carried out more than 7,000 lipo operations . According to Forbes, a gallon of fat could produce about a gallon of fuel. Both types of fules gave the same mileage. But the point in question is not how Dr Britter converted fat into fuel but the fact that it is illegal in the US to use human medical waste to power vehicles.
