I suppose I'm shocked because diesel engines
are inherently more fuel efficient than gasoline engines for starters. The fact that bio-diesel reduces emissions significantly, increases the longevity of the engine because of it's lubricant qualities, can be sourced from non-food crops, all contributing to maintaining our environment and helping clean our air MUCH more than simply using a bit less petroleum. I don't get electric vehicles right now, I think it's much too soon. They put a bigger strain on our power grid charging up, with electricity sourced from coal burning plants and using expensive Li-ion batteries that have a negative effect on the environment during manufacturing and disposal(not a great impact, but still worth mentioning). I see the world adjusting much more easily and effectively to focusing on veggie powered combustion engines.
Who knows though? CD players cost in excess of $3,000 in the 80's when they debuted, but now they are almost obsolete. What will the technological surge wash up on our shores next? I'm not sure, so I'm sticking with exploding cooking oil to run my car......whenever I can afford to, ha!
