After it is requested to make electric power, the responsiveness of the Cat-E is problematical. The Cat-E is not the ideal home power generator because it will take time to get steam up. Upon a call for power, it may take 5 or 10 minutes before the steam generator is putting out the amount of power needed.
Furthermore, a good deal of power will be wasted in this on/off cycling. The Cat-E may need battery storage to even out the power demand curve. In any case, the Cat-E will still require a connection to the power grid to be maintained.
