Nano nano

I just saw a show (“Modern Marvels”) on the History Channel on engines, and I must say I am very intrigued by some of the “alternate” engines they profiled, particularly “nano engines.” They also profiled hybrid engines (as found in the Toyota Prius and the Honda Camry Hybrid) and hydrogen engines.

Nano-technology engines are so small, they’re mind boggling. I’d really like to research them more. They get an official “hmmm” from me …

Another engine they profiled (that was easier to comprehend, for me at least) was the Stirling Engine. It uses no fuel except heat or cold!

Perhaps one of these “alternate” engines will be one of the future answers to our energy “dilemma.”
