Apparently they make cars that run on natural gas. Where do you even _get_ that fuel?
@Motodrachen You probably don't want to be filling the gas tank with actual gaseous gas. That wouldn't work out very well.
I'm sure they run on LPG, and now that I've actually considered that a bit I think we have seen things like buses and semi trucks that run on LPG. It's weird to see a sedan that does though.
@Motodrachen I can't imagine liquifacted coal would make for a good fuel for an internal combustion engine, though.
@Motodrachen I've seen ammonia mentioned as a possible cleaner-burning fuel before. How does that compare, or does it need to use a completely different thermodynamic cycle?
@Motodrachen Incidentally, have you ever looked at bob's mods for factorio? THAT is the real demonstrator of how difficult processing stuff gets.
@Motodrachen I appreciate the circuitry stuff it does. Needing to etch circuit boards and produce components just appeals to me.
I kinda like the metallurgy aspects too, but I think I'm in a minority among our friends. Processing ores in more realistic ways, and being able to use byproducts of other manufacturing processes to extract more metal, just appeals to me.
