Overview

Why?

There were several factors that contributed to the adventure pursuing the making the world's first Waste Vegetable Oil (WVO) powered luxury motor home. At the very least, it was the combination of newly realized technology meeting newly realized dream of freedom.Almost two years ago, while visiting my crazy, dear friend Foster in Los Angeles, he told about some people he knew that would fill up their fuel tank from the oil taken out of a Fry-O-Lator.  Foster is the type of guy that the character "Kramer" from Seinfeld was modeled after.  One summer evening in 1986, he passed an entire spaghetti noodle so far up his nose, it came out his mouth, and he tied both the ends in a know and declared a new fashion. So I was not too surprised to hear this story from him, but nonetheless, I was very impressed. 

I then remembered that years ago, my father told me how a diesel engine would run on just about any type oil, -- even coal dust - and that it was first demonstrated at the Paris World's fair fueled on peanut oil, but years of living with cheap fossil fuels covered up that memory.  How cool would it be for me to get in on this Used Cooking Oil action?, I thought.  I am cheap, and I like fried food.  All I need is a Diesel engine and I am almost done!

Why Not?

Life happened, and I forgot about the excitement of this news. It was about the time right before Hurricane Katrina struck, I had decided that these rising fuel costs were annoying.  More than just annoying, they scared me.  They were scary because they reminded me of how everything we hold dear to our way of life is dependent on energy - and America does not control (at least directly) the majority of its energy addiction.  I am not a survivalist, but I don't like being "bitch to the Man" anymore than the next guy.  I decided then that I too was going to explore this crazy world of vegetable powered goodness, and see if I too could drive on a waste product.  At worst, it would be funny, not too expensive for a life thrill, and at best, I would drive for free on a clean burning waste product.  What is there not to love?  Of course i had not thought out the fine details of collecting and cleaning rancid, liquid puke from behind dumpsters.  No sir, free fuel clogged my judgment.

I began to research the concept of WVO as fuel, and the companies that made these kits I heard about.  There were at least five or so outfits at the time doing this.  Of course, I would have to buy a diesel car, which I did not have because I always thought they sucked, but that is secondary - the desire to do this would see that through.  After a bit more research, it became clear to me that most people selling kits were more like opportunists than engineers.  I am not an engineer myself, but I was always the first kid in school to fix the projector, and I seem to have an inane sense of mechanics.  Certain mechanical things that should be obvious to people are certainly obvious to me.  For example, you should probably not make hot fuel lines out of plastic, make them out of a non-reactive, metal product. sure plastic will work... for a while...  I started thinking about ways I would build my own kit.  Maybe I could build components so good, that I could sell them, since most of the crap I was seeing for sale to the public was easy to improve on with only a few minutes thought.

I would design an automated system with a small micro processor to control the transition from diesel to WVO.  I would use hose in hose, not hose on hose.  I had myself worked into a frenzy right up until I found Frybrid on the web.  Some bastard beat me to it! Here was a product from a guy who had already done what I had wanted to do.  He built a first rate, well thought out, but expensive system, just like I would have wanted to do.  OK, plan B: buy one of these systems.

I ordered the key components that Frybrid sold, and waited, waited, waited.  In the mean time,  I bought a diesel car.  I got a super clean, 1991 Mercedes 350SDL.  If I was going to drive around for free, on a clean burning fuel, I would do it in the biggest, heaviest, most luxurious car I could afford.  

After about 17 years, (OK, four weeks) my Frybrid parts finally came in.  I spent the next three or so weeks, intently installing the components, making my own fabrication from aluminum parts.  I  made a cool control panel, since, after all, it has to LOOK cool! too!  and when I was finally done,

 
Here is the custom control panel I made for my veggie oil Mercedes. 

I had built what I thought was one of the nicest, WVO powered cars I had seen.  This was not some hippie beater, but a serious, later model, last of the large wheelbase  Veggie Benz's.  People on the east coast seem to be a bit behind the West coast.  The word got out in Providence, and the Providence Journal ended up doing a story on my groovy  car.  At least they thought it was amazing here.  Just wait until Rhode Island discovers the Jacuzzi, or the Avocado! I thought this was strange, since I did not invent anything, but I guess it was so unusually to do this on the East Coast, that the editors of the Journal decided to run the artical on the front page of the Sunday paper.  This is big!  I got whackos calling me from far and wide.

 

A Freedom-Machine

The Concept

Since the fun I had with the Mercedes, I become more and more interested in alternative fuel, and waste vegetable oil in particular.  I knew that WVO was never going to solve the energy problems of the world, but I nonetheless was fascinated in vegetable oil fuels and a whole, since they are renewable, domestic and clean.  Any effort towards that end would be effort well spent, so what the heck?  I think that while dumpster diving is a cute fad, gets me to drive for free, and lets me learn some choice words in Chinese, mom and pop Joe American are not going to pick dumplings out of their local Chinese bufet so they can save even a few dolloars a gallon.  No, I beleive I am helping break a catch 22.

No one will be interested in the expense of developing and refining a practical means of developing high yield, non edible grade vegetable oil intended for fuel use if there is no market for the consumption of such fuel.  At the same time, no one is interested in developing and engine, oil burner, or other vegetabe oil eating machine if there is no practicle way the consumer can buy easily available and inexpensive vegetable oil based fuel. .This the catch 22.  I happen to beleive that vegetable oil is a great fuel.  I like it more than ethanol and biodiesel, though they too are both friends of mine.  Vegetable oil to me seems like, well, "Liquid Solar Power"  

Last spring , I was trying to figure out how I could convert one of those 80MPG diesel Smart Cars they have in Germany to run Veggie, but there was so much difficulty getting a SmartCar into this country, I pretty much lost interest. Apparently these little 80MPG cars made by Mercedes for use all over the world are considered way too polluting  to our American air.  I guess those filthy Germans don't care about the American air or environment.  They make SmartCars that according the the US, are simply dirty to drive here. The Diesel SmartCars are illegal to drive on US roads. After all,  the 9 MPG, US made, V8 Hummer diesel must be far cleaner, since they are legal on our roads.  Can you just smell my sarcasm?

On an unrelated note, Anke and I had RVed, a few times by renting those horrible, plastic 23' Class C RVs that are made of sticks and staples.  We really enjoyed the freedom that it offered, especially with kids, but the quality of every aspect of these vehicles was downright insulting.  Most of the components on these vehicles were by my standards, broken before they ever left the factory.  An electric switch to the light should not move the wall it is attached to over 2" in from the pressure of actuating the switch.  Everything about these vehicles was the cheapest, worst of the worst, but I digress....

Regardless of my quality complaints, we had a great time in these things!  The ability to drive and not have to stop when the kids say "I have to pee" is quit valuable. "I'm hungry", "OK, I will make you a sandwich", "I am sleepy", "OK, here is a nice bed".  We had an answer for everything!

Anke and I were really impressed with the sense of freedom we had, especially when traveling with first two, and then three small children.  Wherever you go, you are home.  I think another reason we liked it so well is that RVing gave an usual place where Anke's and my polar opposite interests could unite.  Anke likes to "make house" and be domestic more so than I, and I, in my ADD riddled self, can not sit still, and love to drive, travel, see new things, eat weird foods, look at weird people.  In the RV, I could be driving, while Anke could be cooking.  Sure, this sounds like a 1950's Betty Crocker box, so sue me!

Freedom.  You don't like where you are?  Move! You like where you are? Stay for another day.  Then see what the other town has.

Of course, on night over cheap Lambrosco wine, Anke and I were talking.  "I love the freedom that an RV gives us, but you still need so much money to pay for fuel if you want to travel around", said Anke.  "True", I said.  The fuel cost is the most significant expense when doing any real traveling in one of these, since you can eat, shower and sleep right in the thing.

We thought, "How cool would it be to have a vehicle that is completely self contained, BUT... how cool would it be if it did not need fuel in order to drive?" Wicked cool, I say. 

OK, obviously we did not spend more than a few hours contemplating before we concluded that we would need some type of fuel.  We are simply not going to wait for them to invent an anti gradational ray guy.  The next best thing is a free fuel.  Yes, a free fuel that is environmentally friendly -- who wants all that guilt of selfishly polluting the world because of your personal desire to drive a huge vehicle around for pleasure.  A waste product that is a disposal liability for the people who have it.  A fuel that is as umbilicus as McDonalds and Wendy's.

"A waste vegetable oil powered RV" I said.  "That. That would be cool", said Anke.

Of course there are always maintenance costs, but this seems to be the closest thing to a "Freedom Machine" that we could come up with while drinking our cheap Lambrosco.  Maybe one day, if we decide to get an RV, we can play with this idea some more.

The Details

In order to realize this vision of a Freedom-Machine, it had to meet certain minimum requirements.  If it failed to meet any of these, it may  still be cool,. but not as cool as it ought to be.  Some original specifications came to mind immediately:

  • The vehicle has to be BIG. 
    • No sense in putting all this money and work into a vehicle that was not big enough to be comfortable with our three kids.  Since the fuel would be free, fuel consumption was not really a consideration.  In fact, the larger the engine, the larger the savings.  No more 23', nope, lets over compensate!
    • The gross weight should be high enough so that all the unknown tanks and systems needed would not press against the maximum rated weight of the vehicle.  A "tag" axle was required.  a tag axle is those extra tires that sit behind the rear wheels of big busses.  Big busses have them and they serve at least two purposes. They provide about 10,000lbs of additional weight carrying capacity, and they provide significant additional breaking power in the event that you wish to slow down for some reason.
  • The Vehicle has to be nice,
    • We hated, no, that is not a strong enough word, we loathed most RVs and their thin plastic accoutrements.  I have a BIG problem with plastic made to look like real wood (ironically, on my Mercedes, the wood looks like real plastic, but I digress) Although I learned this lesson years ago, the conversion of my Mercedes last year confirmed this.  It is like I always say, "If something is worth doing right, it is worth doing."  I would hate to spend a lot of energy on something that was not the best I could afford.  If I got a cheap ass RV and went to the extent I would to convert it, it would have been quite a waste if it were a sticks and staples, plastic crap box.  I am glad I went about 3 times over budget on Elbee, and in retrospect, I have to talk myself out of secretly  wishing I had spent more money I don't have on a bigger, nicer RV.
  • More details
    • Additionally, I wanted at least a 400HP motor, computerized leveling jacks, a diesel generator that I would also convert, lots of full, bay storage for the tanks, and the most important thing, Anke said she would only do the project if we got an RV with a washer/dryer.  Apparently, the ability to self sufficiently  do laundry is a critical component in Anke's schema of what makes a "freedom-machine".  I humored her on this one.  After all, I needed a musical horn, like in RV, the movie!

    OK, lets start looking, and make sure that whatever we picked has no technical complications that would make the conversion to  WVO painfully complex.
