Visited the Homebuilding and Renovation show at NEC and saw for the

time a MicroCHP which really looked the dog's doodahs. It was on the
PowerGen stand but of course nobody had any details on how to buy one.

Does anybody know the commercial situation with these ? When will they
be
available and for how much ?

The unit in question is a "Whispergen", but don't get your hopes up.
They were originally designed to provide power, DHW and heating for
yachts and as such they are a tad under-sized for domestic use. The
electrical power output is laughably small and they only makes any kind
of sense if installed in large numbers and used to feed current back
into the grid when supply exceeds demand.

They can supply about 50% of a homes electricity usage, as most is below
1.1kW. If using below 1.1 kW it turns the meter backwards. Grid-tied.
