Do you mean the domestic bokashi composting things or the industrial scale gas making things?

The latter, but I am wondering how small they can go...

Depends what you want to do with it. Lots of regs about pressure vessels, storage of combustable gas etc.

Dispose of waste and produce gas.

What pressure do they run at?
If the regs for storing gas are too onerous, we could just burn it as we go to make electricity.

Yes, I believe most of them do that. I was thinking about festivals...

You don't think "Crapfest" would be popular then?

They do actually have a big show on waste disposal down in Paington, I think it is, every year. There were some delegates staying at the same hotel in Torquay as we were a few years ago. One of them was trying to explain his plant to me, but I just didn't understand I am afraid.

How about flaring our personal offerings.

Might be all the heating we can afford in the future

That is a substantial part of my point.
I don't believe these things are hugely expensive, and they can produce gas endlessly.
They should be almost everywhere.

Cowpats used to be used as fuel. Maybe slurry to fuel brick is the way forward.
