8-bit processor runs on nothing but AIR

Instead of electric impulses or spasers, the processor uses pneumatic valves, which are operated by changing the air pressure in a tiny chamber below each air channel. The binary signals are transmitted with air: Sucking means 0, blowing means 1. Poetry, people. This is what this thing really is. Pure poetry in action.

Hasn't this technology been around for a decade already?

Pneumatic devices are actually much older than that

Most basic operations (OR, AND, XOR, NOT) are very simple to do with pneumatic stuff. Making a whole processor out of it, however, is quite impressive.
