On Nuclear power: It is estimated that there is enough U-238 (99.3% of all available natural Uranium) to last 5 Billion years at todays current usage rates in fast breeder reactors. Reprocessing can poentially recover up to 95% of the available Uranium and Plutonium from spent nuclear fuel.
And BTW we are only up to 3rd Generation reactors. 4th Gen are thought to not be available for another 20 years
On gas fueled engines: The higher octane rating of gas allows one to build oneself an engine with a significantly higher compression ratio, I'm talking in the order of 14.5-16.0:1 and possibly higher. Hello instant torque and power, just what every 460 big block needs.........more
