alt Hacker NewsI'm not the same guy but I can verify that the advert for the impossible micro-evaporative cooler quoted impossible performance capabilities.
YouTube adverts frequently contain fraudulent, misleading information. It appears that no law is being broken.
I can believe that, I'm just here to point out that some of the laws being not-broken are the laws of thermodnamics. You can cool a room cheaply with dry ice, for instance. There are tricks.
