RV Processes Own Fuel on Cross-Country Trip

An anonymous reader writes "Frybrid has realized the dream of Dr. Emmet Brown's Delorean: putting garbage directly into your vehicle, and have it be turned into directly into fuel. This past fall, Frybrid installed a system into a 40' luxury RV that sucked up waste vegetable oil from the back of restaurants, removed the water and filtered it, and then burned the dry and cleaned vegetable oil as fuel. The family drove their converted RV from Seattle to Rhode Island on $47 worth of diesel fuel. Plans are underway for a smaller version of the system to fit in the bed of a pickup truck."

    They did this on Mythbusters, they took used cooking oil, filtered it, and put it into a standard Diesel truck. It ran perfectly normally.

    As they observed on the show, the only reason it's such a cheap source of fuel is because it's a waste product now. If people start using it as fuel, it will cost just as much as Diesel fuel does.

      Given current production methods, certainly. If we had the same sort of money going into farming that we now have going into finding new sources of oil, I'd bet we'd find better ways.

    Used vegetable oil has to be the stupidest replacement fuel ever thought up. Sure it's cheap now, it's a waste product... but not for long the way these soon to be short lived startups are going.

    The only ones who will profit from a Veg Oil economy will be McDonald's and the like... their oil will be just as valuable before and after use, thus they spend nothing on oil at all, instead of throwing it away at the end of the day they sell it for their cost.

    Eventually demand will surpass capacity to produce... and this is probably 1% (http://en.wikipedia.org/wiki/Vegetable_oil_used_a s_fuel#Waste_Vegetable_Oil) of the current petroleum demands... sure it's better than draining an non-renewable resource... but it's no replacement.

    I surely wouldn't want to stake my future wealth on it by starting a business around it... the economics just don't work... if you are successful it won't take long to put yourself out of business. When the veggie oil starts matching unleaded, you will have capped.

      I don't think it's that bad of an idea myself. It's cleaner to burn, and if the demand goes up there will be farmers happy to produce more vegetables. I'd rather the waste vegetable oil goes toward reducing our petroleum dependency than some of the alternatives, and I don't really care if the fast food industry is one of the beneficiaries. Maybe they'll start processing the oil for cars instead of people, finding it more lucrative, and make their food a bit less greasy. We can only hope.

      Even if the waste oil is only 1% of petroleum usage, which is not all turned into diesel, if the US ramps up its resources to produce more vegetable-based fuel we'd be able to dramatically reduce the amount of petroleum going into vehicles. Most diesel vehicles in the US tend to be used in freight transport. Imagine smelling french fries or popcorn instead of the current diesel when you're behind a large truck that's belching smoke all over the place. I know what I'd prefer.

  3. Why is always a cross country trip? by tap · · Score: 4, Insightful

    When ever you read about someone with this wonderful used fryer-oil powered vehicle, they're always taking it on some cross-country trip. Is that because if they stay in one place they use up all the fryer-oil from the local restaurants?

    I'm only half joking about that. The people who advocate this stuff have the same program as the Verizon employees who can't understand the difference between 0.002 dollars and 0.002 cents. They just don't seem to grasp the orders of magnitude difference between the amount of corn oil this country produces vs the amount of crude oil it consumes.

    Thats just it, it will not catch on and prices will remain low, or at least mostly free.

    As it is, Diesel is not a popular technology in the United States. Most consumers in northern states avoid it for fear of jelling in cold weather, and Diesel all-around has gotten a bad reputation for small vehicles. Consumers prefer Gasoline to Diesel. The only place where Diesel is strong is in the transportation industry as just about every transportation truck fleet is Diesel powered. Now, considering that consumer Diesel vehicles are a small market to begin with, Waste Vegetable Oil (WVO) vehicles are an even smaller fraction of this market.

    No commercial automobile manufacturer is going to make WVO an option, so any WVO vehicles on the road will be strictly conversions. The number of conversion kits will be limited to a select number of individuals who are either "in-the-know" or have been talked into making the change by someone who is familiar with the concept. I suspect that while numbers of WVO vehicles may fluctuate from year to year, after an initial rapid growth of the industry, the volume of WVO vehicles will plateau and stay maintained at several thousand. This of course assumes that early adopters do not cool to the idea and replace their WVO vehicles with non-WVO vehicles, causing a dip in overall WVO vehicles as other alternative fuel vehicles generate interest or fast food restaurants limit access to WVO for fear of litigation should their WVO cause damage to the vehicle.

    While this is an interesting case study, and WVO vehicles generate interest, I doubt that the concept will take off, or that WVO vehicles will ever become "mainstream" despite their obvious draws.

    I also question how biodiesel and federal regulations figures into all of this, and what impact biodiesel will have on WVO and vice versa. Will WVO be converted in bulk into commercial biodiesel thus creating a demand on WVO? Will new federal regulations concerning Diesel emission quality limit WVO conversions? As biodiesel moves dependence away from foreign oil toward domestic renewable fuel, will the price drop enough to make WVO conversions financially impractical?

    No, this technology will be niche at best or dead in a decade at worst.

    This would only be good news if:

    • The current used vegetable oil was currently being thrown away, lubricating landfills I guess.
    • But it's not, it's already going into special dumpsters, which I suspect get dumped into recycling systems that filter the oil and resell it for non-human consumption by mouth uses, such as candles, ointments, plastic feedstocks, greases, etc....
    • there were a LOT of veg oil per person being used. But if you think about it, it's doubtful that you're using more than a cup of oil a day, which doesnt translate into a significant amount of energy. Most people use at least a gallon of gas a day-- offsetting that with a cup of veggie oil is not a big win.
    • And let's not forget a good percentage of that oil is effectively consumed in the process of shipping, filtering, and re-refining the oil.
    p. Perhaps it would be better overall to nip this "waste" in the bud, and we all cut back on our consumption of fried foods. Less waste and less "waist"-- a two-'fer
