Hey Marcus,
Great project!
I'm from Oregon, but now I live offgrid in Costa Rica. Looks like you have the same power setup I've got, but we use micro hydro.
Anyway, I was at the GEK gasifier workshop in Berkely CA a couple months ago, and we worked on a project that converts a lister engine into a woodgas burner. They started putting it together and had it working by sunday(an on hands prototype the visitors helped put together). It worked!
It would sure be nice to burn wood chips and have clean exhaust than used oil.(Yuck!)
You should check it out. Since you only need the gasifier and no engine or gen set it could work out very well for you.
They are really into this project and want to power listers all over the world with alternative fuels.
The exhaust from this is water CO2 and a few NOx's. It's definitely a cleaner option.
Look forward to seeing your progress.
Roger
