Haven't the Chinese exploited this on a fairly large scale in the
countryside? Perhaps the Chinese embassy could help with some plans.

>My understanding from an independent researcher who had tried to
develop a small farm scale biogas system for many years is that
temperate climates are a huge obstacle to small scale biogas systems.
The most efficient microbes are very picky about temperature, so you
need a very warm and stable space for them to do their work. I think
thats the reason many have tried and only a few systems in the warmest
climates have actually succeeded...
