Alternative Fuel Help
 

After recently learning that rotary (wankel) engines can not only run on hydrogen, but does well, and that storing hydrgogen in a problem. I was thinknig about generating it on demand from something like this (https://ussolid.com/hho-generator-hho-water-welder-for-jewelry-making-and-project-polishing-with-one-gas-torch-set-95l-h-2800.html?gclid=Cj0KCQiA7IDiBRCLARIsABIPohgqIse54H l73W2zJLzdZtULjOAkuzOXEa1sRKeb0m6iBtmQV2WJ3jUaAjxI EALw_wcB)

However I don't know how feasable this flammable water based fuel is, nor do I know how to calculate and test air fuel ratios. Or even know whether that device would make too much or not enough potential fuel.

Tldr: I have an idea, but no technical knowledge to take it forward.
