Thank you for not adding "all the livelong day" <G> Seriously ... Check out ORC

I work for a railroad and was quite interested in the discussions. It lead me to research on the steam engine: http://en.wikipedia.org/wiki/Steam_engine I learned a lot. I think Rossi, assuming he has something, might talk to Dean Kamen. The inventor of the artery stint, insulin pump and Segway has some great ideas on efficient Stirling Engines. Anyway, I learn more reading and researching Vortex than I ever learned in engineering school. T
