I have tinkered a bit with steam and have come to the conclusion that it is just too dangerous for a bike. It just moves out of my comfort zone. However, it might not be a bad idea on a trailer. However, it would be hard to monitor and control. However, for the joy of doing something that is seldom done, it could be worth it.
The same applies to the OP idea, it is terribly impractical. However, if the purpose of doing it is to do it, it would be a fun project. This subforum is filled with people who are on similar paths, yet may have very different destinations.
