Bjarney, I am amazed reading (on a webpage of all things) an encouragement to change from DC to AC in 2003!

Do I take it therefore that there are still some residential premises powered at 120V dc in NY,NY or is this just for utilities like lifts etc.? It does talk about lighting. Do they use the same NEMA receptacles? It reminds me of the high-pressure hydraulic mains for powering lifts in UK cities whose pipes are still extant - but now tend to contain fibre-optic cables!

Same webpage - steam powered air-conditioning (2003!). I know this is an electrical forum, and I vaguely understand gas refrigerators, but how on earth do these work?
