Just thought you might like to hear about a real life conspiracy that I am unfortunately very aware of.
Slightly OT or certainly tangential to your post.
Conspiracy? or is it economic responsibility?
I don't for one moment doubt that we can build more fuel efficient cars or that technology is kept off the market. But every time this sort of issue
is brought up it always considers the automotive industry in isolation.
The cost of the pumping oil out the ground, the pipelines, the refineries and storage, are spread over all the industries that use it.
If we were to take away the need for gasoline , which is roughly 50% of a typical crude oil Barrel, then the effective cost of the other constituents
rises. The economies of scale would change drastically. Plastics, air fuel, and feedstock for the medical industry would all leap up in price.
Drastically so in some cases.
And this is just the base cost. Shipping and air transport costs would jump etc.
Our use of the gasoline car engine has effectively indirectly propped up a lot of the other industries that use oil.
You're car would likely destroy health care in a lot of poorer countries (and a few industrialised ones), if introduced overnight. An awful lot of
3rd world charities would go out of business.
Car engines aren't the problem. It's easy to get rid of gasoline as you know - I assume you're being truthful - it's the other uses we put oil to
that are the tricky part.
We need time to advance our synthetic technology, and find alternate sources for other oil product based industries. Let's face it. regardless of
what we run cars off - the energy industry will always be trying to make a profit off us.
We need to change gradually, otherwise we risk trashing the world economy, and indirectly killing 10's of millions of people. I'd suspect any
drastic alternative or improvement in terms of the gasoline engine efficiency, will continue to be sat on and introduced as needed.
Interesting link if you haven't come across it before. Lot's of reports , that are worth a read if you are interested in this sort of thing.
PS - apologies if this sort of thing has been posted elsewhere.
