Air Powered Microprocessor

Air powered CPU
I seriously doubt that you will be playing Super Mario Brothers on this any time soon but it would be fantastic for a self operating chemical analysis machine.

Each pneumatic valve is operated by changing the air pressure in a small chamber below the air channel, separated from the circuit by a flexible impermeable membrane. When the lower chamber is filled with air the membrane pushes upwards and closes the valve, preventing the binary signal flowing across one of the processor’s junctions.
Sucking out the air from the chamber reopens the valve by forcing the membrane downwards, letting the signal move across the junction.The two researchers used the valve-controlled channels to produce a variety of logic gates, flip-flops and shift registers, which they linked together to create a working 8-bit microprocessor. That means that the longest discrete pieces of data it can handle are eight binary digits long, like the processors used in 1980s consoles such as the Nintendo Entertainment System.
