Special K is an abandoned power plant control room in Hungary. Built in the 1920s, it was a pioneering example of Art Deco industrial architecture and featured a dramatic oval-shaped room lit by a large skylight. The plant originally ran on coal but was converted to natural gas in the 1970s. Much of the original control equipment remains intact on the green metal wall panels. A concrete bunker housed an air raid shelter during World War 2, underscoring the control room’s role in a critical infrastructure at a turbulent time.
How big an area? I’ve only seen that on college campuses and military bases before in the US.
In Europe those often cover whole cities.
That’s cool. Good use of waste heat. We’re too NIMBY and adverse to paying for infrastructure that takes time to pay off. Much more efficient to do it centrally and extract power than use cooling towers at power plants and wasting your exhaust heat out of chimneys in home furnaces.
