Americans are "Carnot Engines."
This cannot be denied,
Operating at max efficiency,
In this we take great pride.
Wasting not a single joule,
Amazing as it seems,
It’s in our genes to minimize,
Our energy input streams.
Our outputs, in turn, are maximized,
Pushed to the very top.
There’s no room for improvement,
Sans a living-standard drop.
* "Carnot's theorem is a formal statement of this fact: No engine operating between two heat reservoirs can be more efficient than a Carnot engine operating between the same reservoirs." -- Wikipedia
If you actually believe the above ditty, have I ever got some stuff for you!
-- A Perpetual Motion Car ("pre-owned", by a little old lady from Pasadena, who only used it to drive to church on Sundays) and
-- A very hot item: a Cold Fusion refrigerator/freezer (only used once, by Pons and Fleishmann -- to cool their celebratory champagne).
