Subject: Listers and Gasifiers and Lister Prices
Message: Dear George, I’ve been tinkering around with alternative energy ideas (and some implementation, although most in the thermal
realm) for some time. I am thoroughly in love with gasification and have wanted to add an engine to a system for years, but could never find one that would satisfy my criteria of simplicity and longevity.
That is, until I came across the Lister.
Here is my question. Do you know anything about running listers on producer gas? AS I understand it can be done in two ways, one by starting the engine on diesel and then once its warm and running, switching to producer gas, or by converting the lister to a spark system and running on 100% producer gas. I would like to know your thoughts, since you keep coming up all over the place as a primary go to guy when it comes to all things Lister.
Secondly, what will a new Listeroid cost me? I always try to have 2 of whatever I depend on so affordability is an issue, although not at the expense of longevity.
Your comments and input would be very much appreciated.
I’m sure it makes some of my visitors unhappy when I don’t endorse wood gas as a great thing, and I can only say we need do our home work before we get excited, and certainly before we pick an engine!
Wood gas has a VERY low BTU value, so first you need figure how much of it you can stuff into a cylinder, and how much power you can make. If you’re attempting to stuff without a compressor, you better have a lot of cubic inches, I’ll guess you’ll need about 7 PSI or so to get enough fuel/air in the combstion chamber to be happy with the power output of a Lister 6/1, and I’d be tempted to look at a small four-cylinder to get some work done with wood gas instead.
Wood gas is an interesting study, we’ve had really smart people looking at wood gas since Carnot’s time, and rather significant investments in wood gasification in days prior and after WWII, and interest by DIYers ever since. Is there even one commercial Wood Gas power plant running at a furniture plant where we are likely to find the most ideal fuel for one.. why is that?
I’ve mentioned several times that I want to post the data results of a wood gas system.. show me a well done study where one is charged, and just how many KW of real power (like KWHs or electrical power) comes out of the thing, without your hands being busy every second with the controls and feeding.
I can buy a LOT of electricity for the same price as a minimum wage employee, and when I add in the cost of a wood gas plant, it looks pretty expensive to me.. If wood gas were easy and practical, we’d all have it.. Regardless of what Nuts like Kari Norgaard think, the oil companies can not suppress a good and workable idea.
Feel free to challenge me, …. do bring me the story of a guy who lights a fire and goes off to play his banjo as the wood gas plant merily makes Kilowatt hours.
The way to sell all the Wood Gasifiers you can make is to install your plant at a furniture factory where they have ideal mill ends dry and fit for fuel, train a mill operator to stoke and operate the plant, and have it operate a prime mover that drives a generator connected to an inexpensive meter that will keep track of Killiwatt hours produced and for how long, the time required to stoke and service the plant, and other important data. This should include cleaning filters, and any time spent tending the gasifier. We also need hours on the engine and a study of engine wear. We’ll forget the cost of fuel all together, as this is only diverts our attention aways from the most likely problems with the gasifier.
Higher than anticipated amounts of labor to keep the plant fed, and operating in relationship to the real power produced.
Doesn’t this sound like a great project for University Students? And shouldn’t it lead us to the next question, why haven’t more of their creative Mentors applied for a grant to study same?
Maybe I should mention.. I did get an email from a Professor in Italy. He sent a picture of a masterful assembly they did, it looked as nicely made as an Itialian Sports Car! .. his last sentence.. ‘if we do another one, it will be far different. That was six or more years ago.
All the best,
