Urgh. I saw this post right after sending an email to a local science professor that I knew bordered on the cranky (I even admitted in the text, half-jokingly: the difference between a crank and an eccentric is usually money. Eccentrics have more and that buys some deference that cranks are denied 
). Haven’t heard from him, strangely enough.
I wasn’t talking about perpetual motion or reinventing the turbine, thank goodness.
