Master electrician Allen Gallant shows us the workings of the new emergency power generator, a quiet natural-gas-powered unit that will supply the house's ""essential services"" (heating plant, refrigerator, well, some lights) with electricity in the event of a blackout. Beautiful wooden garage doors go in, and we get a tour of their construction, installation and operation. In the kitchen, Dick Silva begins installing the new cabinets, while our master carpenter visits a converted woolen mill, where a local cabinet maker is building the Silvas an entertainment center out of rare and beautiful tiger oak. Back on site, inventor John Crowley shows us his line of ""kit of parts"" wainscoting.
