I could be completely wrong about this but I figure we won't be using oil one hundred years from now. Science is moving so fast its just unbelievable.
Somebody already figured out how to combine aluminum pellets with gallium to create hydrogen on the fly. I heard it on the radio (news) so can't share a link.
We'll probably have plasma baby milk warmers by the time the next century rolls around.
Besides, oil so so eighties.
