1. Could Baggage have used Fluidics in the design of his engine? Say if Babbage had gone to the people who build pipe organs and player pianos could he have gotten his engine built and the world would have sound log tables decades earlier?

  2. I ran across this old digital computer patent 3190554 where air is use to do the computing. Bet it would be a snap to built this computer today at some tech school using 3D printing. Make a cool project for the students.
