The oldsmobile is an example of a failed project. There is a reason this never went into production.

You can patent anything you want, they don't check if it works or whether it could work. I can vouch for that as a holder of two patents.

If you want to do something realistically, go for steam. It is in the perfect spot of being doable by someone with machining and metalworking experience and being powerful enough to produce some useful power. Yeah, a moderate pressure hobby steam plant will be pretty much capped at 15% thermal efficiency and that is if you use superheated steam a condensing., but people do it as a hobby and it works. Of course I am talking of people like this guy - https://www.youtube.com/watch?v=85OmZU3dZpA and not the retards that put pressure cookers over open fire and rig crappy engines out of pneumatic cylinders and duct tape. And this guys engine is still on the lower end of the spectrum as it has no superheat and uses slidevalves and is noncondensing.
