An ionic wind to cool laptops may blow fans away
“The Electrohydrodynamic (EHD) ionic wind pump technique involves applying a voltage to an electrode, which produces a high intensity electric field. Air molecules surrounding the electrode tip ionize and as they move from the corona electrode to the collector electrode, they collide with neutral air molecules and their momentum pushes these neutral air molecules across a hot spot, cooling it down. Such ionic-cooling systems have been demonstrated in research labs before, but Tessera is the first to test the technology inside a working laptop by replacing the standard rotary fans with EHD blowers.”
