Good morning Dustin,
Back in 2008 when we made the “ Coast to Coast and back trip we were scheduled to stop at location and events along the way. It wasn’t practical to take folks for a ride to try to prove we were running without gasoline so to demonstrate we had an 8 kv generator with the gas tank taken off and a long hose ran to the truck gasifier. This way everyone could see the only connection to any fuel source was a hose that contained no gasoline. We would take this opportunity to prep wood for the gasifier .
The truck gasifier would be warm ,( not necessarily up to normal temp yet ). I would charge the system with the pusher blowers to push gas through the long hose, kill the blowers and let the generator pull the draft through the gasifier . We usually would run the generator operating a table saw with me cutting wood while my partners were explaining the system.
We usually ran the generator 30 min to an hour .
Also in the winter of 2008 I put on demos at a college campus in Kirksville Mo where an energy conference was going on . At each break in the conference I would operate the generator powering the saw. Next day at a farming conference / event same town . About an hour is as long as I would operate at a time.
If one has a good char bed and the gasifier is warm I think he can make gas that will be OK for a small generator. This would be OK for charging up a battery bank with a truck gasifier . For any longer use I think this would be asking too much of the gasifier and I don’t think it could handle that amount of turndown ratio.
