When I was about 8 years old I discovered that there was a few volts AC between the hot and cold taps in my parents house, so I rigged a night-light in the kitchen using a bicycle dynamo bulb. It glowed away for years, mostly dim, but sometimes very bright, until I learned enough about AC power systems to realize how dangerous it was. The hot water cylinder and piping were grounded to the utility ground, and the cold water piping was grounded via the metal water pipe feeding the house, but the hot and cold were isolated by a plastic header tank. We lived right next door to a power company 11kV/230 transformer. By the grace of God, nobody was ever electrocuted in the house!
