The issue isn't carbon.

It's greedy as far as oil companies are.

As far as small platforms, it is possible to build generators that will support small passenger cars by production on demand, and it has been done.

I've personally designed and built some power cells.

That way, no violent hydrogen gas is carried around as a bomb.

However, it would require people to have water and a catalyst.

If people could see just how simply hydrogen cars can be, people would begin retrofitting existing vehicles, and many massive corporations would be out of business in a few short months.

I know a few of you say conspiracy, but that's how it is.

Regarding a truck engine and the amount of work required for this heavy workload, idk if it could be done that way.

Perhaps Cummins will pioneer the way to freedom for the rest of us to do our own; who knows.
