Made by Hugh Longbourne Callendar | Science Museum Group Collection

Car with experimental compressed air transmission. Made by Professor Hugh Longbourne Callendar in the Physics Department workshops at Imperial College, London. The car is based on a 1906 20hp Model F Stanley steam car. Professor Callendar installed a c1911 Swift, two-cylinder, petrol car engine where the boiler would have been on the original Stanley car. This petrol engine powered an air compressor, providing compressed air to power a 20hp Stanley steam car engine which drove the rear axle. The car is fitted with a Swift radiator and different hood so does not look like a standard Stanley steam car.
