A few years ago, I worked with a startup company that went to Finland and bought one of Vesa's beautiful stainless steel gasifiers. I was told it is identical to the one in his book used to power the Lincoln Mk V with a 400 (see http://www.ekomobiili.fi/Tekstit/woodgas_as_fuel.htm). They removed it from the single axle trailer and mounted on a large flatbed. At one time, they had it connected to a generator but the genset isn't there anymore. They want to liquidate the equipment- a 30' gooseneck trailer rated at 30,000# (as I recall) and the gasifier complete with filter and cooler. I've asked for pictures and a detailed description of the trailer.
The gasifier has very little time on it. For some reason, one of the other vessels (filter or cooler) had some corrosion issues.
If anyone is interested, let me know. Email: toddt58 (at) gmail.com.
By the way, I work with stainless steel welding and process equipment at work. Vesa's work was absolutely top notch!
