Hey @rmme - Good luck! I enjoyed reading your post. It's an interesting thought experiment.
Actually, there is quite a history of people trying to invent a water-powered car engine, or pretending to have done so. This link may be of interest: https://en.wikipedia.org/wiki/Water-fuelled_car
About extracting hydrogen from water to power the engine, the article says,
- "According to the laws of physics, there is no way to extract chemical energy from water alone. Water itself is highly stable—it was one of the classical elements and contains very strong chemical bonds."
There are some reports that Toyota have developed a water-powered car, but according to Forbes they are false reports: https://www.forbes.com/sites/rrapier/2025/06/15/no-toyota-didnt-build-a-water-powered-car/
On the other hand, hydrogen-powered engines produce water vapour as exhaust - so water is the end product, not the fuel.
Another thought... In many parts of the world water is not so plentiful, so water-powered cars - even if they were feasible - might make water shortages even worse in those areas.
Maybe solar-powered cars would be a better alternative? I just found this entertaining video about a guy who made a 100% solar powered car!
Thanks again for your post. 😊
