Would this water from air device work?

    Hello everyone,
    I came across this device and was wondering if this is actually possible?

    It is possible, as stated in the article it would be nothing new.
    Yet it would have a high Energy consumption, as roughly 1mc of air holds between 4-50g of water (depending on temp pressure etc.). For 1 liter you would need 20-250mc of air. The Energy from moving this much air alone would be high for the small output of water.

    Extracting water from air is not new but this product is supposed to use ultrasonic frequencies to condense water vapor into nano droplets which would then freeze at 10-15C (50-59F) in the right conditions.

    I know that you can get ultrasonic humidifiers but I've never heard of a dehumidifier that works using ultrasonics.

    PrAnan, I am with you. I am aware of ultrasonic humidifiers. I can not claim to know everything but all of the conditions that I am aware of that will cause water to freeze at 10-15 oC involve something other than standard atmosphere. When I go to the link it shows a relatively simple device that does not appear to have any provision to achieve these conditions.
