I have read the article. One error I note is the claim that a 1 KW
output can supply the average household. When sizing emergency
generators for homes, the conventional wisdom is you need around 10KW.
Of course that's for peak loads. Obviously if all you're running is
lights you could get along on 1 KW. But run the TV and the dishwasher
and a few other appliances simultaneously and it mounts up.

One point that did impress me is that water in the alcohol does no harm
-- in fact it contributes additional hydrogen molecules that are also
separated by the catalyst.

Somehow I think rhodium is scarce and expensive. Don't know about
ceria -- never heard of it in fact.
