This is the first time I have heard of Jean Pain's system, but a
bit of Googling suggests it's just a big biogas digester.

These systems scale down to the size of a beaker, but if you're
going to use it for cooking, heating and power generation you
will need a pretty big unit!

Here's a good reference:

And now you know some more terminology, Google will return a lot
more references.
