Thousands of people undergo liposuction surgery every year, but short of turning all those extra pounds into soap (a la "Fight Club" or Silvio Berlusconi), it is all thrown away as biohazardous waste.
Similar to the "Roadkill Refinary" idea (see link), you could melt this fat down into a fuel usable for diesel cars.
A mobile clinic in a van would come to your house, suck out your fat (possibly with the aid of engine vacuum lines) in a mobile opperating room, then render and filter the fat on its way to the filling station.
This fat would be rather heavy and probably burn rather poorly, probably stinking up the place, but it would get rid of unwanted waste and produce valuable fuel.-- discontinuuity, Sep 06 2005 Roadkill Refinery Roadkill_20refineryMy inspiration: an idea on how to make diesel oil out of dead animals [discontinuuity, Sep 06 2005] (Half)baked! http://www.wired.co...ve/14.05/start.htmlLiposuction yields 1 liter of biofuel for a powerboat [discontinuuity, Apr 26 2006] Peter Bethune on the liposuction table http://www.solarnav...r.net/earthrace.htm"Mr Bethune said Mr Rees had to probe around a fair bit to get anything and the 100ml of fat extracted wasn't enough to yield fuel." So, that Wired article would be off by an order of magnitude then, and I'm not sure whether any of the fat actually hit the tank. [jutta, Apr 27 2006, last modified Jan 16 2007] Fire in the hole!

[DrCurry, Jun 15 2006] BBC News: 'Berlusconi's fat' moulded to art http://news.bbc.co....ainment/4110402.stm"An art work purportedly made from excess fat from Italian Prime Minister Silvio Berlusconi has been sold for $18,000 (£9,862)." [discontinuuity, Mar 07 2007] Apparently, some 'artist' stole the fat from Prime Minister (of Italy) Silvio Berlusconi's liposuction and turned it into a bar of soap for an art exhibition.

sp: diesel-- wagster, Sep 06 2005 This would be great here in America. Our cars are too inefficient at burning fuel and our bellies are too efficient at storing fuel. Now we can kill two birds with one stone.-- JephSullivan, Sep 06 2005 //Suck your fuel out of chubby people//
Quote of the day.-- DesertFox, Sep 07 2005 Bypass the suction and just stuff chubby people into your fuel tank? Bad taste, sorry.-- david_scothern, Sep 08 2005 Welcome back [UB], pull up a chair, have a donut.-- wagster, Sep 08 2005 Bypass the fuel tank and just ride fat people around.-- sleeka, Sep 08 2005 Bypass the other people and just eat a lot and go places.-- JesusHChrist, Sep 08 2005 Bypass the chubby people and the biodiesel and walk? Naah. Americans wouldn't go for that.-- elhigh, Sep 08 2005 Unless a Wendy burger stop was...naah-- skinflaps, Sep 08 2005 Well, apparently someone has already done this. A Wired Magazine article this month shows the diesel powerboat that Peter Bethune is trying to pilot around the world on biodiesel, some of which came from his backside.-- discontinuuity, Apr 26 2006 Eeew! Ouch! And congratulations!-- jutta, Apr 27 2006 I live in America, But I have the opposite problem.-- BJS, Jun 15 2006 Hey, be sensitive. Not everyone thinks living in America is automatically a problem.-- david_scothern, Jun 15 2006 Have a bun and gag on it EEEW!-- the dog's breakfast, Mar 07 2007 Human flesh is rumoured to taste a little like pork, so a car running on this might smell pleasantly of frying bacon.-- hippo, Mar 07 2007 Really? I've heard it's more like veal, but who knows except for a few cannibals.
Either way, I think most of the smell goes away when you turn it into biodiesel.-- discontinuuity, Jun 20 2007 Would fat people be paid in cash like blood donors? That would finance additional foodstocks for consumption, which could be sold, and so on, a sort of cottage cheese indusrty.-- nuclear hobo, Jun 20 2007 No, thin people would be paid in cash. You wouldn't pay them until you'd taken your money's worth.-- Cosh i Pi, Jun 21 2007 random, halfbakery
