Nifty video of a home-built "stratified downdraft gasifier," a.k.a. a wood-gas generator. Wood gasification was an important 19th century fuel technology, but was finally displaced by petroleum-based gas. Wood gas made something of a comeback during WWII, borne of necessity. It may come back again, after the apocalypse, when we need to try and outrun the Main Force Patrol on our way to Thunderdome. Just pray we can stoke enough chairlegs and clapboard to get us all the way to Bartertown.

i couldn't discern from wikipedia, but is this a more efficient means of harvesting the energy potential in wood? As opposed to a very efficient wood burning stove that is burning very hot?

It's a process for creating a gas mixture (H2/CO/CO2/, others) that can power combustion engines (among other things). That's why it became "popular" again in WWII (in Europe) as oil became more scarce. As far as I know (which isn't far) you don't need any dramatic changes to power an internal combustion engine, besides the gasification unit itself.

What a great video, fun to watch. But I wonder how much more efficient this is than using the wood to power a steam engine.

Here's a little nerd thing I did on making woodgas.

In case you'd like to see a VERY large example of this in action, head over to perpetual Burning Man artist Jim Mason's website.

way awesome. I'd love to do this.
how efficient is it? and how realistic is it to use/store the woodgas?

At the end of the video, in the credits, they provide a link to Open Source plans for this.
