Any of you a stirling engine expert? I want to make a bicycle that uses the temperature differences at the points of contact with the bike that would help propell the bike. Like, the temperature differences between your ass and the seat, your hands and the handlebars and the friction caused at the points of rotation. The more effort you put into moving the bike, the more of a temperature difference you create and the more help you get to move it. If it offered a lot of help then it would propell you faster, then the ambient temperature would be lower due to the wind and you’d be getting warmer from effort, causing a greater temperature difference and even more help. If we could all ride a bicycle around using half the effort it takes now that goes twice as fast, we wouldn’t need cars, we could ride a bike 80km/h to work and the only energy it would require is an apple.
Some caveats is that it has to be small enough to fit unobtrusively on a bicycle frame, weigh almost nothing, be super cheap and easy to construct and require almost no maintenance.
