===Electrostatic air movement and corona discharge effect cooling===
The cooling technology under development by Kronos and Thorn Micro Technologies employs a device called an ionic wind pump (also known as an electrostatic fluid accelerator). The basic operating principle of an ionic wind pump is [[corona discharge]], an electrical discharge near a charged conductor caused by the ionization of the surrounding air.

The corona discharge cooler developed by Kronos works in the following manner: A high electric field is created at the tip of the cathode, which is placed on one side of the CPU. The high energy potential causes the oxygen and nitrogen molecules in the air to become ionized (positively charged) and create a corona (a halo of charged particles). Placing a grounded anode at the opposite end of the CPU causes the charged ions in the corona to accelerate towards the anode, colliding with neutral air molecules on the way. During these collisions, momentum is transferred from the ionized gas to the neutral air molecules, resulting in movement of gas towards the anode.

The advantages of the corona-based cooler are its lack of moving parts, thereby eliminating certain reliability issues and operating with a near-zero noise level and moderate energy consumption.<ref>{{Cite web |url=https://thefutureofthings.com/3057-ionic-wind/ |title=Ionic Wind – Chillin' the PC |date=2 January 2007 |access-date=11 April 2021 |archive-url=https://web.archive.org/web/20130613114337/http://thefutureofthings.com/articles/46/ionic-wind-chillin-the-pc.html |archive-date=13 June 2013}}</ref>
