This may open a can of worms, but what about abiotic oil?

There are some that say tapped wells are filling back up. Like oil could be a condensate from the crust of the earth interacting with the core, or some such thing.

True or not, it's fascinating.

If only we could invent some sort of thing that could use, say steam or something, to run an engine. Maybe we could boil water with a renewable resource... like bio matter.
I call it: The steam powered go mobile! We could even make one big enough that it could run on rails, just like a train! But I digress, fantasy thinking.

Laziness breeds innovation
