"Recycled vegetable oil
 
Recycled vegetable oil, also termed used vegetable oil (UVO), waste vegetable oil (WVO), used cooking oil, or yellow grease (in commodities exchange), is recovered from businesses and industry that use the oil for cooking.
 
As of 2000, the United States was producing in excess of 11 billion liters (2.9 billion U.S. gallons) of recycled vegetable oil annually, mainly from industrial deep fryers in potato processing plants, snack food factories and fast food restaurants. If all those 11 billion liters could be recycled and used to replace the energy equivalent amount of petroleum (an ideal case), almost 1% of US oil consumption could be offset. Use of used vegetable oil as a direct fuel competes with some other uses of the commodity, which has effects on its price as a fuel and increases its cost as an input to the other uses as well."

Like I said before, I agree that something has to be done, and this may be viable at some point in the future, but at what cost?  The waste oil comes from production of "food" items that are non-nutritious at best and deadly at worst.  Petroleum is dirty, no doubt, and a limited resource to boot, but the technology to use other sources MORE economically is not yet in place.  I work designing and building analytical equipment that researchers are using for biomass and coal gasification resarch as well as CO2 sequestration (greenhouse gas mitigation) and hydrogen storage for fuel cells, so I am kind of close to this. ;)  I also have many years of experience in the analysis of petroleum, natural gas and pollution measurment (H2S, SO2, NOx).

Anyway, have fun in Czech, they have awesome beer there. 8)

I used to frequent political forums, but I grew tired of them and came here to get away from all of that.  Can't we all just drink a beer?   ;)

I don't see how talking about the science behind alternative fuels is political?

Alright, I am unzipping my mouth, but only to agree with your statement and thank you for your expertise. I did not mean to imply that UVO is the solution to all the environmental problems, just that it is a solution. So if it's only 1% that means there is only 99% to go! Reduce is the first part of the equation right?

Phil +1 on walking to the store. and do have fun in the CR. enjoy your new car.

I don't have the car yet :-( It costs lots of moneys, and for the moment I do not have too many moneys. I'll get there eventually, but it requires prioritizing for other things like taxes and diapers and beer.

Plus there's a 4 month lead time on orders from the factory. Still will be fun to go, once I can get out there.

I'm pretty sure they sell those in India for real though, apparently they rig up the AC to work by passing a fan over the tank when it's decompressing air. Pretty neat!

Otherwise there's this:

If you lose your license for too much speeding, alcohol, whatever, you can still drive, but you can only drive a voiture sans permis, they max out at around 40 mph.

That's pretty neat! I just had a vision of NYC filled with tiny, brightly colored toy cars zipping around on poots of compressed air!

I don't want to get into it or steer the conversation in that direction, but trust me, it is.

you don't have to much to worry about on that front. The mods are pretty good about stopping things before they get out of hand. But for the most part we monitor our selves.

science, on the other hand, can generate some pretty heated debate on here from time to time. so look out.

I hate to "hijack" a thread, but I would like some more information on beer in the Czech Republic. I'm planning a trip to Prague in November and am interested in beer near the city center. Three good ideas so far, but three posting pages to get there...

There are projects under way to produce bio-diesel from chicken by products too.  Pretty much any fat can be modified to work as bio-diesel.

Keep in mind that with Mr Diesel designed his engine his plan was to make if run on vegetable oil.  It was later that petroleum companies made "diesel" fuel the standard.

I agree ethanol is a boon-doggle but I am looking forward to all the stainless steel that will be on the market in Iowa when the industry collapses.

In my Internal Combustion Engine course a long time ago, it was stated that Dr. Diesel's first experimental engines worked on coal dust, as Germany has coal. The abrasion of internal parts made that idea a non starter so to speak.

Back to beer in Praha.

I feel quite confident that in a century or so, textbook sentences addressing that fact will begin, "Unfortunately,"...
