Based on a small Honda CNG engine sounds like a good idea, just too expensive for me.
Looks like they are for sale, but not anything in my neck of the woods.


But here's a PDF of the Honda Micro CNG...

The PDF says it's a 163 cc vertical shaft water-cooled engine. That should give us some inkling of an engine size for a tiny Co-Gen.


And here's an Ebay link for natural gas & propane carb from 1.5 HP and above.

Now we need to find a very small, highly reliable water cooled engine, and some kind of dynamo. Looks like the design of the exhaust gas heat recuperator is also pretty sophisticated, since it scavanges not only the sensible heat but also the latent heat of vaporization (condensing heat recovery).
