20 thoughts on “Does it work? Solar Powered Ventilation System”

  1. Since these appeared in commercials in the 1990s here in the US, I'd always wondered what kind of value proposition could have been presented by the owner(s) of this device to the various auto manufacturers ( maybe a licensing deal with each competitor? ) , to list a similar function as a purchase option installed alongside the automobile's climate controls where it could source air from the existing fresh air ductwork.
    Solar cells of that size and output were cheap as were the motors.
    Vehicles would've been kept secure as well instead of what I recollect coming up in conversation / news outlets as the weak point of entry for a vehicle theft or the contents therein.
    Given the expense and relatively low number of remote car start systems installed especially for the time, the profit margin of a solar powered ventilation feature w/ a serviceable motor and solar cell seems like low-hanging fruit at first blush.

  2. Tinted windows will make it so the solar cell isn't getting enough light to work. IF your windows are tinted, you need one where the solar cell is outside the window.

  3. yes it does works, but only if you put four of the same devices. And it also will work if you let it for long time and when temperature increase

  5. you should crack open the other side of the window so that the fresh air will replace the air inside. it will not work if all windows are shut.
