I know someone who uses chipfat-biodiesel(UK) and it smells like burning meat. Perhaps this is because in the UK tallow(beef fat) is used a lot in frying.

Today while walking along the road I smelt it a few times and it seems to me that if too many cars start using the stuff, walking or cycling along the road will be pretty unpleasant.

Would it not be better to burn it in a powerstation? or better yet, the cessation of animal fat for frying, then the oil can be used as animal feed, as it was pre-BSE days.

Whoa...traffic jams that smell like barbeque? Duuuuuude!! *drool* Almost enough to want to go get stuck in rush hour for aroma therapy...

I doubt that would happen. The market is probably already saturated with the usage of the fats, and intentional production of this for fuel would not be cost effective.
As bio-fuel becomes more common, a lesser and lesser percentage will be used oils, let alone meat fats. The only way this will not happen is if the used oil is already being wasted in a big way, or we will eat a lot more fried food (in a big way).

If only. But he said beef tallow, didn't he? Any civilized person knows a proper barbecue serves up pork.

pork? a REAL barbecue involves several huge slices of steak getting seared over a warm bed of good charcoal with a little bit of apple or mesquite wood thrown in for good measure..
has anyone else noticed that most of the people that would want to use cooking grease to fuel our diesel powered vehicles are probably people that are opposed to killing and eating animals themselves?
i didn't say ALL, but i'd bet a good chunk of them only eat plants..

I have a coworker who converted an old VW Golf to run on veggie oil. I can confirm that it smelled pretty bad if you were behind his vehicle when he stepped on the accelerator. It smelled neither like "French fries" nor cooking meat, but like burning vegetable oil (go figure).

He recently sold the car on eBay for a ridiculous amount of money, and has upgraded to an old Mercedes Benz, which he converted to use the same fuel.

BTW: Both cars run on both diesel and vegetable oil. He only switches to vegetable oil once the engine has warmed-up, as he pre-heats it using a heat exchanger.

Edited to add: This guy isn't a tree hugger, or vegan. He is, however, a gearhead and has a nice machine shop in his garage.

Seared? That's grillin', my friend. Nothing at all wrong with tasty meat hot off the grill...I do it all the time...but let's not confuse that with barbecue. Real 'cue is cooked low and slow with loving care and lots of smoke. Wood smoke isn't just "thrown in for good measure"...it's an essential part of the process. Succulent ribs, pulled pork butt, crunchy bark...can't get that from grillin', no sir.

Oops...this is startin' to sound like a religious discussion. My god of fire versus yours, eh?

we must have a bit of a language thing going on here. Alaskan and Minnesotan are probably two distinct dialects with the same words meaning different things.
'round these parts, barbecuing is anything cooked on the grille- preferably over a "real" fire made from charcoal and/or wood.

Sounds like it, but just as long as there isn't an argument over "science fiction" versus skiffy ("scifi") or the definition of "bogus" it should be fine.

Same here in California, though we might detail what kind of barbecuing is being done, if it wasn't clear from context.

In Australia it's always, "Throw another shrimp on the barbie." Which is why we have a genetic predisposition to be tall.

Yep, there probably is a language difference...I'm a Southerner married to a Minnesotan...but really, I'm just having fun with the discussion. I'd readily agree that most casual outdoor cooks make little-to-no distinction between grilling and barbecuing. But in general U.S. usage there is a technical difference between the two methods. (ref)

When it comes right down to it though, I'd only consider the difference truly important if someone tried to serve me a pork butt seared on the grill or a lean sirloin steak barbecued for 12 hours. Both are bound to be a bit on the chewy side.

pork barbeque kebab and grilled beef steak

I know! I will get a constant hankering for steak. But the really bad news is the likely increase in stomach ulsers as the smell of yummy food on every street triggers a stomachs everywhere to begin producing that deadly digestive cocktail without any food for it to attack.

Erm, you do know that turning livestock into cannibals was itself the cause of the BSE crisis. Feeding an animal more animal of its kind sounds very wholesome circle of life stuff, until it catches what killed it.

Actually, the idea of animals eating their own kind doesn't sound very "circle of life" to me. In fact, for some reason it seems very wrong.
Maybe I just like my circle of life to be a little bigger.

Back on topic, perhaps my friend's car doesn't smell like cooked meat because most of the restaurants around here use vegetable oil rather than lard for cooking.
