Before you consider YiWen Tseng’s idea completely farfetched for creating a sustainable and organic fuel system, remember how many inventions throughout time have seemed that way at first. Tseng has drawn out a system in which 3D bioprinted cow stomachs would be installed in the back of each car, using a filtering and storage process of their own to send methane gas to the front of the car for powering the engine which would use methane on demand. The stomachs would be fed grass and treated as live organisms by mechanics.

Below you's find a conceptual model of what a car like this could eventually look like. Opinions?
