Oil will be replaced about as soon as we get our flying cars Popular Science Mag. promised us by 1999, back in the 60's.
Not for hundreds of years if ever will a better energy storehouse than a gallon of gas be produced.
Now, efficient us of same, that's the story.
Ok,... Now...., if High Pressure Fuel Injection had been adopted soon after it was perfected 60 years ago, we would have been able to double our fleet ave. MPG and have clean air to boot (i.e. never needed cat. convertors).
Oh, yeah, another thing we would have never needed, . . foriegn oil.
Think about that, and 'round up the culprits while your at it, I'll get the rope.
Liquid Hydrogen. However, it has a couple of problems such as it is cyrogenic, expensive, causes hydrogen embrittlement of iron, and is always looking for a place to catch on fire. However I will opt for diesel as it is more efficient and has a higher energy content than gasoline.
Disagree completely. Energy density in supercooled superconducting capacitors will exceed that soon.
