Couple of months ago, I read the paper"Flight of an aeroplane with solid-state propulsion", which was interesting. Few days ago, i was watching a Youtube video about a cooling gadget for smartphones and comparing it to the Nubia Red Magic 3 which is a gaming oriented smartphone. Magic 3 has a built-in fan with about 1mm thickness. It does a good job though, and makes the phone pretty stable under heavy tasks. Anyway, I quickly thought about the mentioned paper and tried to find if there is any cooling system based on that method (corona electrodes) for mobile devices. Fortunately, there was a paper named "An Electro-Aerodynamic Solid-State Fan and Cooling System" and dated back to 2008. I could also find a thesis here for cooling means. Concluding, this time gap (about 12 years) means probably no one considered it as a reliable solution, but I've some good feelings about this method. I can see two obvious reasons here for neglecting it: High voltage and low efficiency. But I'm still curious about that if it can become a useful method for cooling mobile devices in the future (considering its very small form-factor and almost silent nature). I want to know if anyone has any thought in agree or against this method and why. Thanks
