I wasn't sure =which= topic to post it under. I thought I saw other wood gasifiers in this topic. FM please move if it is the wrong area!

It definitely fits a niche where you don't have the time or equipment to do the wood prep, and/or want long unattended run times. You could do a pellet mill as well, but you don't have to get started. You can run it in your backyard in town without drawing much attention.

Thrive Energy released their gasifier system as an open source project. Their design uses small (US typical) sized wood pellets and was originally designed and is used for small generators and engines 400-700cc. It has long run times, tar free operation and the grateless design avoids numerous issues common with gasifiers. The video was just posted on assembly of a no-weld kit that is for sale that contains all the hard to make (if you don't have a metal shop), parts.

I have followed wood gas for years, and this is a pretty neat simple system especially for off-grid and you don't want to mess around with wood prep. I am looking at getting one for a ceramic kiln, and a foundry as well as backup generation.

I tried it. The char was wet from when i put out the fire in the restort. It took about a half hour to go through a 5 gallon bucket at about 90rpm as you have to trickle it in.  It stops with any brands or if you overload it and you have to grease the contact parts. But I like the consistency of it as it is like a medium sand.   If it is damp it comes out fine then it will ball up as it dries, but it breaks up easily. If it is wet, it comes out of the grinder as goo. It squeezes a lot of water out of it.  I didn't bother to sift out any of the ash first. It is straight from the retort.
