Rain Proof Car Ventilation

 Building cars that take air in without rolling windows down

It is always like 130 degrees when I get into the car. This causes me to suffer, and it causes the air conditioner to have to work harder.

People who design cars should have a screen that would keep bugs out, but let air ventilate your car. It would take air in from under the car, so rain can't get in.

       I guess the aim is to give sufficient ventilation that air will convect through the cabin of the stationary vehicle, preventing the solar oven effect.   

       The problem is that you'd need to put some pretty big holes in the body, half of them near the bottom.   

       Holes in the underside are a problem because they will allow exhaust fumes, road spray, dust and other debris to enter the cabin when the car is moving.   

       Perhaps this could be achieved with door hinges which operate both in the usual manner and also allow the lower edges of the doors to be opened to a 1" gap. The 'door open' warning would alert the driver before moving off and the vent area could be quite substantial. without the need for extra holes.   

       There would still need to be a rain-proof vent at the top of the car - perhaps a sunroof which open 1" parallel to the roof.   

       Incidentally, my 1966 Landrover has 2 large vents just under the windscreen, complete with mesh screens and just as rain proof as the rest of the body!

       My sun roof has a rain guard (thank you, Germany!) so I can leave it popped up in the summer.
