Yi-Wen : Methane-powered concept car Royal College of Art graduate Yi-Wen Tseng has imagined a car powered by bio-printed organs, using synthetic biology to turn a cow’s digestive process into a fuel system. When designing the Digestive Car, Tseng considered ways to harness cows’ well-known tendency to expel large amounts of methane gas. By pairing the cow’s digestive process with 3D bio-printing – a processproposed for use in organ transplants – the designer identified a way to transform this into an opportunity to create an alternative fuel system. The transparent rear half of the car houses four synthetic stomachs – modelled on the quartet found in a cow – and each of the organs facilitates a different process, including filtration, methane production, and digestion.
