Where do lighthouses get their electricity from?
Where do lighthouses get their electricity from? So lighthouses either get their electricity directly from the mains or they have supplies of diesel delivered. In fact, many probably do both. Older lighthouses used to burn gas. If there was a supply of town gas (e.g. from coal) they might have a direct supply through gas pipes - just like you may have in your home.
Why did lighthouse keepers go mad?
When dust, dirt or other impurities built up in the mercury, part of the light house keeper's job was to strain the mercury through a fine cloth. Though not understood at the time, mercury is a deadly poison. One of the symptoms of mercury poisoning can be the onset of madness.
Do lighthouses ever get destroyed?
American lighthouses have been swept away by tsunamis, destroyed by hurricanes, toppled by erosion, gutted by fire, even targeted by weapons of war.
