Way before electricity, city officials saw the benefit to lighting up the street so that people could find their way around. When electricity was in its infancy, some towns took the easy way- instead of replacing hundreds of gas lamps, why not just built one tower, or several for bigger cities, and make them very tall? Electricity produced enough light for people to get around, even from a very tall tower. As far as the electrical mechanism goes, they were primitive, but they worked. Eventually, cheaper, safer, and more efficient electric streetlights were developed, and these "moonlight towers" were replaced. Except in Austin, Texas. Austin decided to keep the towers as part of the city's personality, although they have been restored and rebuilt. The city still has 29 of their original 31 towers. Tom Scott gives us a rundown on the towers, how they worked, and what they look like today.
