SOLAR POWERED CAR VENT IN ALL PAKISTAN, KARACHI IN KARACHI

>td >td >With only 4 solar cells, the panel’s voltage measured an expected 2v.  The short circuit curre The other day, I saw an ad for a solar powered vent for my car.  The device was advertised to help keep the inside of a car cooler by pushing out the hot stale air and drawing in cooler air through the car’s own air vents.  I bought one of these devices to see if it might work.  What a joke.  This thing just does not move enough air. When placed out in the sun, I could almost feel a bit of wind coming from it. But, in theory, the concept may have some validity.   When exposed to direct sunlight, the inside of a car can reach dangerously high temperatures.  How hot?  On a warm summer day, I placed a wireless temperature sensor in my van.  The hottest temperature I have seen so far was 147F.  That would kill someone if they spent much of any time in the vehicle.  Pets would succumb to such heat in a very short time.
