Let's talk about oil

That's fine for some things, but unrealistic to think it will solve our liquid fuels problem. Stuff has to get from one place to another, simple as that

With dream-level future technology (like fusion) energy might become cheaper, but it will never be free.

Where is your socialistic spirit?
