W&N: What about turning synthetic oil into gasoline or diesel?
It's undoubtedly far-fetched, but who knows what science will do in the future.
If production of biofuels - especially from biomass and waste matter - becomes more efficient, then that's probably a better solution than synthetically-created fuel. It's using something we wouldn't otherwise need - waste products.
Although burning biofuels still produces greenhouse gas like regular fuel it's still more "carbon neutral" (I dislike the term, but just to illustrate) because it's spent only a matter of years being grown - and can be replaced - rather than millions of years being formed under the ground. It's easy to offset the carbon impact of biofuels because you can simply grow more plants...
Again, I don't see the increasing push for efficiency becoming in any way something that will ruin the car industry.
Think of one of the as-yet barely explored technologies - reducing weight. Some makers are starting to get it, and reducing the weight of cars has benefits
everywhere. Performance, economy, handling, reduced materials usage (also good for the environment - if you're using less steel, that's less raw materials being processed). Cars are getting stronger all the time, so you're not sacrificing safety by going lighter either.
Especially with companies like BMW and Mercedes. Both the i3 electric car and i8 plug-in hybrid will have aluminium/carbon shells, and Mercedes is hinting that the top-spec version of it's next E-Class
will be all-carbon, and
770 pounds lighter than the equivalent made from steel. That's a massive difference.
Likewise, improving engine efficiency isn't exactly a bad thing, as a more efficient engine has as many benefits in power and driveability as it does in fuel economy. That's why, today, we have cars that are more powerful than ever, yet more efficient than ever too.
Yeah, I'm not buying the whole "future will be glum" stuff. Anyone who thinks that is completely underestimating the ability of carmakers to be one step ahead of whatever legislation can be thrown at them.
