Excavators in Brisbane have found 134-year-old rare electrical cables with links to light bulb inventor Thomas Edison.
The cables, which were laid under William Street to provide electricity to the parliamentary precinct, were removed on Tuesday to allow the new Queen’s Wharf casino complex development to go ahead.
The “Edison tubes” were designed by the late inventor and built by his American company. Brisbane was the third city to have the technology after London and New York.
“We were the first place in the southern hemisphere to have this technology, and just the third in the world,” said supervising archaeologist Tina King.
“It’s a milestone for Brisbane’s development as a city and we’re making sure to take the utmost care in the conservation of these important artefacts.”
The tubes were made of cast iron casing, asphaltum-based pitches, and two to three copper cores.
Parts of the cables will be housed in Sydney’s Powerhouse Museum, Brisbane’s Commissariat Store Museum in Brisbane, the Highfields Pioneer Village in Toowoomba, and Parliament House as well as the Science Centre in London and the Thomas Edison National Historical Park in New Jersey, US.
