The Zone

Liquid cooling used to be the stuff supercomputers were cooled by.  Desktop computers started with no heat sink, just the processor.  Then the heat sink arrived, followed by the fan.  These days we have liquid-cooled processors. So the question is, what's next?

Ion.

The stuff that powers the TIE (Twin Ion Engine) Fighter in the Star Wars universe, and can be found in some homes to purify the air. These days you can also find it powering some hair dryers, as Ions are cooling and won't harm the hair like hot air.

Heck even NASA has a spacecraft powered by an Ion engine, called Deep Space One.

Isn't it about time computers were cooled by Ion as well? 

Well, Intel-funded researchers managed to achieve 250-percent heat-transfer efficiency by using Ionic wind on processors, opening a possibility for future processor cooling.  Here's to better computer cooling via Ion than messy liquids!
