[QUOTE="SDMF, post: 315605, member: 412"] I could happily motor along w/internal combustion engines for the rest of my life, I have nothing against them and I have at least a layman's understanding of how they work. It's no great feat but I could take apart and re-assemble a small-block Chevy it'd run. The above aside, a 4-stroke IC engine running @ it's peak efficiency would still only be 25% efficient if there were no efficiency lost to friction and heat. There is efficiency lost to friction and heat in every IC engine. Doesn't matter how many gears you add to a transmission or how many MPG's you squeeze out of aerodynamics or weight loss, the fact is, you're starting off with a minimum of 75% room for improvement. If someone can cypher a more efficient way for any reliable, safe, and abundant power source to turn the wheels on an automobile, I'm all ears. That said, I'm not sacrificing performance or reliability for efficiency. I grew up in the days of 55MPH Interstate Highways without a TV, phone, or iPad in the car for entertainment. The CB radio and radar detector in dad's car were the pinnacle of early 80's tech inside a car at the time. I'm not interested in going back to 200Mi worth of ND Interstate Highway taking 4hrs.
