I came across this video when browsing for gasifiers. In german language, people also call downdraft logburners gasifiers, which in many ways is right.
The Windhager retort is a true TLUD. The remarcable idea in this one is the double bottom sluice. Whether it makes charcoal or not sure is only a matter of discarding earlier or later and of the distance between the 2 discs. (Shure a gas analyzer can tell us when it's time to let the charbed drop.) I would air cool them, though. I have a lot of bad experience with long term warping of hot metal plates. I like the idea.
