Good point: <It might be better to just go to DC and stop using AC altogether. > We have lots of transformers turning 230 volts into low volt direct current for lots of little devices. Refrigerators could be lower powered with top-opening lids Some freezing, some cold and some cool. They could run on DC People have one big monster with a vertical door letting heat in constantly. I suppose in winter that doesn't matter because the houses are heated so the heat might as well come from the refrigerator. In summer it's hard work if air conditioners are used [to have a refrigerators heating the place up only to have to then cool it all down again[. I rarely think about electricity other than reliability of supply. It could do with some security and efficiency improvements. Mqurice
