Why not run microturbines on the gas rather than piston engines?
We get asked this a lot for some reason. Piston engines are cheap and easily available. Microturbines are not. Old car engines will run happily for years on wood gas and using secondhand engines reduces eco-footprint considerably over buying either new engines or microturbines. Microturbines are far less tolerant of contaminants in the gas stream (eg particulates and moisture) than piston engines. Also, when a car engine breaks down in many cases you can fix it yourself or worst case it can be taken to the local mechanic. But try fronting up to your local garage with a busted microturbine and see how far you get.
