This innocent looking, ornate lamp in Carting Lane close to the Savoy Hotel, was designed by JE Webb and was devised to work on methane gas produced by the sewage system. This early eco pioneer designed the Patent Sewer Ventilating Lamp in 1895 and sold the design worldwide. The post is hollow to allow the gas to rise up to the elements. Little did the guests at the Savoy realise that their effluent was being used to illuminate the nearby alley. The lamp now runs on standard gas, which in itself sounds antiquated.
