Our local gas utility here in Red Sox Nation has been running radio ads
aimed at homeowners promoting the Honda household-cogeneration
equipment, which includes mention of selling extra generated electricity
back to the utility, and gummint credits to help you purchase your
equipment.

Anyone here have any experience with them?

UNLESS there is one of those silly laws in place that requires the utlity to
buy back power at "retail" rates there is no way this can make sense.
The homeowner would be buying fuel at "retail" unless (again) there is some
kind of special deal with the gas company.
But the real killer is the "wear and tear" on the relatively small sized
home power plant. Even with "Honda Quality" after about 6,000 hours the
engine would have to be replaced/rebuilt.

Interesting concept. For electric generation, it's small, only 1KW,
but I guess it's sized that way because any larger and the
corresponding waste heat would be more than needed for a typical
home. What does the marketing say about the cost to buy and
operate, life expectancy, how much you make selling electricity back
to the utility, etc?

No, sorry. Just a general comment: I was a little surprised to read the
description, since to me, cogeneration has always meant taking the
previously wasted energy from one process and recovering it. (The
classic example is using excess steam or other heat from an industrial
plant to generate electricity.)
Not that this isn't an interesting application, but it is really just a
way of capturing thermal energy from an IC engine that would otherwise
be lost, and using it to heat water.
To me, a *real* cogeneration unit would be one that would capture heat
from gas appliances, say, and use it to generate electricity. Probably
not practical on a single-home scale, but maybe on a multiple-unit level.
