New Microprocessor Runs On Thin Air
From The New Scientist:
There's no shortage of ways to perform calculations without a standard electronic computer. But the latest in a long lineMovie Camera of weird computers runs calculations on nothing more than air.
The complicated nest of channels and valves (see image) made by Minsoung Rhee and Mark Burns at the University of Michigan, Ann Arbor, processes binary signals by sucking air out of tubes to represent a 0, or letting it back in to represent a 1.
A chain of such 1s and 0s flows through the processor's channels, with pneumatic valves controlling the flow of the signals between channels.
