Here's a few guys here in Sweden who modified an old Volvo to wood gasification, and took a tour around all of Sweden this ummer. 5400 kilometers or something.

Around Sweden with Wood in the Tank

And here's the photo page, including pictures of blonde female groupies. Apparantely wood gasification is hot with the chicks over here... (OK, only one picture, but I bet that got your attention)

Some facts about the car:

acts:

Top speed: 90km/h (105 km/h with dry birch wood)

Acceleration 0-100: Some times :)

Wood consumption: 1 cu m / 1000 km

Cruising range on one load: 70 km

Start-up time: 2-10 minutes

Kerb weight: 1460 kg

The producer-gas systems weight: 260 kg

On route, they visited and kicked life in an old tractor, to run on wood gasification/producer air. Blog entry, text in swedish, but there is a video of the engine once they got it going:

And the wood gasification enthusiasts in Sweden have another website at http://www.gengas.nu/ but swedish language only. Sweden more or less survived on wood gasification during the entire WW2 (and that included agriculture), although car use naturally was much, much less than today.

And here we have the Finnish version :)

Finns are more neat and clean. Must be the great availability of alchohol for ... cleaning purposes. But as I recall, Finland has been a Swedish province for all but the last 200 years, so we get some of the credit. Hrmph.
