Kiren chose to focus her small project on the two gas engines in the basement of the Cambridge Museum of Technology. One engine is still operational and can produce gas, whereas the other is out of action. They used to be fuelled by gas from the gas works situated where the Tesco Superstore now stands. To run the engine 35ml of oil is poured in to the side funnel on the engine. In order for the engine to start, the small wheel on the end of the engine has to be spun approximately 32 times for it to run for 30 seconds. This fuels the engine which allows the large wheel to do a complete 360 degrees in 40 seconds. Gradually the second wheel begins turning and, hand in hand, they both spin with a speed as fast as 0.02 seconds per rotation. Below is Kiren's isometric burst of the gas engine wheel. She felt that the gas engine wheel no longer operating symbolised a motionless, arrested past, whilst the operational engine and wheel carried that history into the present, celebrating the industrial past of Cambridge.

Kiren proposed to elevate the gas engines from the basement of the museum up into the valve yard, which is a grassy area outside the museum where there are 10 valves. These valves were once used to control the flow of water and sewage in the pumping station when it ran water and sewage directly to gas holding tanks as well as to the sewage farm in Milton. By bringing the gas engines back to the surface she hoped to unearth the industrial history of Cambridge by making them a prominent feature of the valve yard, provoking questions from visitors about the use of both the engines and the valves. Below is a photograph of the valve yard and an isometric burst of Kiren's small project proposal.
