A pocket power station which gave electricity to an entire Devonshire town in 1959 and is now based in Wales will be honoured next week.
The Proteus engine at the Internal Fire Museum at Tanygroes, Cardigan is the world's only working exhibit of a dial-up gas-turbine power station.
It was so futuristic it could be started and stopped remotely via a public telephone line and up and running at within minutes. At full load it generated 3MW of energy.
Next Monday it will be given an Engineering Heritage Award from the Institution of Mechanical Engineers (IMechE).
IMechE Heritage awards only go to unique examples of engineering excellence that have left their mark on history and/or have made a significant impact on society and mankind.
One unique mark of the Proteus was that someone in another part of the UK could dial up (via Datafonic control) and switch it on remotely.
IMechE's Professor Isobel Pollock, who will be presenting the award, said: "Our Heritage Awards only ever go to artefacts or projects of significant engineering heritage. Here, in the heart of Wales, we have something that is not only unique but was a truly visionary British engineering concept that richly deserves to be recognised across the world."
It was the genius concept of engineer Bill Irens, the then Chairman of the South Western Electricity Board in 1959 now SWEB Energy and was indeed ahead of its time.
The Bristol Siddeley Proteus then paved the way for a whole generation of much larger unmanned power stations are around today. Its purpose was to provide power, which it did up to 3MW, in remote areas that were at risk of power loss in bad weather.
