Disagree completely. Energy density in supercooled superconducting capacitors will exceed that soon.
The point I'm making is we could have doubled our fleet ave. MPG for the past 50 years with simple fixes like High Pressure Fuel Injection.
Your a first, most naysayers say 'Oh, it's too hard, so much pressure".
Meanwhile, look at the hydraulic pressure in our brakes?
If it could be done there, why not at the fuel rail?
