Cheaper than a Victory, that's for sure...
The price jump to get to the next size is small--most of the money is wrapped up in manpower, overhead, and profit.
Cost is never a good indicator of quality. Most people would prefer to purchase things that work instead of trying to "save money" with a half-assed backyard DIY project that never gets finished. The best home gasifier design I am aware of is the GEK

Warren Weisman wrote:Wood gas runs very poorly in larger, high compression engines that might be used in farm trucks to get produce to market. In which case home-brewed ethanol or biodiesel or even using the syngas from your gasifier through a Fischer-Tropsch catalyst to make some F-T diesel. .
Warren Weisman wrote:Keep in mind heating is a necessity and vehicle fuel is a luxury. Using gasifiers for vehicle fuel all of the heat is lost. Same as it is for petroleum of course, only energy in post-carbon future will need to be maximized better so we don't end up cutting down all our forests for energy (a la Haiti). Considering what a superfluous luxury automobiles are and how simple it is to make electric vehicles, it might make more sense to use a combined heat and power gasifier to make electricity at the same time it was heating your home and recharge an electric vehicle or NEV for local commuting.
Warren Weisman wrote:Big difference between running a vehicle and running a vehicle efficiently. You can run a diesel on windshield wiper fluid. That doesn't make it the best fuel choice. You can only fit x volume of gas or liquid in a cylinder at one time. At 135 BTU/cu.ft. wood gas compared to 1,000 BTU/cu.ft. for natural gas or 140,000 BTU for a gallon of diesel, wood gas efficiency is non-existent.

But watch those Victory Gasworks videos where he runs the big 20 kW generator and then welds with it and almost kills the engine. It just doesn't have the power for low-end torque under a load. It would do the same climbing hills in a vehicle.
it is, but doesn't include all the parts.

One of the main points I want to get across is that anyone who considers converting a vehicle to run on wood gas should attempt a dual-fuel configuration that uses a much smaller gasifier. I believe this general approach can minimize many of the disadvantages. Also, I believe the Vulcan gasifier is a good candidate for it's simple, compact, and low cost design.

Hey Steve. First, I recommend you contact people who know more than I. To that end check out the forums at driveonwood.com. Next, consult the Handbook for Biomass Downdraft Gasifier Engine Systems (available on line). That will provide a basic intro. You might also contact the engineers at All Power Labs as they have a large stationary Diesel generator currently dual fueled with a large gasifier (it's a 100 KW, 1800 rpm unit).
First, I assume a vehicle application, right? I would try restricting the air intake to a Diesel just enough to increase manifold vacuum to ensure there is enough differential pressure across the gasifier for operation. The ideal setting would be the one that provides just enough air flow through at idle to keep the gasifier hot enough to make a clean gas, but also does not pull too much air through the gasifier at high engine speeds that it overheats.
Steve Bartlett wrote:Hey thanks Marcos. I did more checking on the All Labs site, and they do have some info on the dual fuel idea. It seemed (I'll have to check again) that they said larger engines like eight cylinder were too big. They said what you said about restricting flow and that is how the wood gas is drawn in.
I'm out looking at pickup trucks today, and if I go syngas it'll probably end up being a gas truck. I love diesels, especially F-350's, but WVO seems like such a lot of trouble these days and getting worse.
Dave Burton wrote:BUMP! I think this is a neat discussion! Has anyone built a system for cars like Wayne Keith's Woodgas System and gotten it to work? What were the biggest difficulties in implementing the design? How much did it cost to build? has anything gone wrong before, during, or after the build? This question is not apply to just the device itself and its build; it may include neighbors filing complaints about it, government interference, dogs stealing parts, etc.. If there was an issue, what happened and how was the issue resolved?
