110 volt lead pots have only been sporadically available since the incredible jump in the number of guns purchased, new shooters and hunters added to what was once a population of 50 million. It's now estimated to be approximately 55-57 million. A significant jump in under a year's time.
OTOH, 220 volt pots have been far more readily available. A 220 volt pot is also more efficient, and heats up faster.
If I was moving into a new house, the first thing I would want is a three phase, 220 volt, 400 amp service. Then, my options for running electrical machinery would be virtually endless.
A European, 220 volt, induction stove, commercial, or household, is the most efficient means of cooking by a very large margin. The best commercial induction stoves are virtually unknown here in the USA. In Europe, most of the best restaurants have spent the money to upgrade, as the cost savings after a couple of years proves to be worth it. Plus, the heat control is instantly transfered via magnetic induction. Faster even than natural gas. And, the cleanup is easier because there are NO openings on the top of the stoves surface.
