USE CAR’S EXHAUST TO CLEAN CUSHIONS (Feb, 1932)

USE CAR’S EXHAUST TO CLEAN CUSHIONS
Using the exhaust gas of the automobile to clean the upholstery is the accomplishment of a recently invented device. An aluminum attachment is fastened to the exhaust pipe and the engine is allowed to idle. As the exhaust gas passes through this device suction is created at the inlet hole. Collected by a nozzle, the dust and dirt are drawn through the hose and expelled into the air at the rear of the car. It is made in three models, for cars of different size.

    I like it, just for its sheer lack of efficiency. Why directly power your suction device when you could just use the Bernoulli effect generated by the waste product of an idling engine?

    Not to mention giving your car that fresh CO fragrance!

    OMG Stan,

    1. CO is odourless
    2. It’s obviously using classic fluid dynamics to generate a low pressure. That means you are sucking sh** in, other than spraying your car with exhaust.

    Oh, and it’s not efficient at all. Just look at that long thin tube, and imagine if you have to breath thru that.

    Idling is not cheap either, considering gas is like a buck a liter.

    Isn’t it the Venturi Effect that creates the suction used for the vacuum? It’s a condition that is created from the Bernoulli Effect. The faster and lower pressure flow through a constricted opening (Bernoulli) can be transformed into a partial vacuum (Venturi). There’s no CO pushed into the car, it’s all suction.

    Considering that gas was probably less than a few cents per gallon in 1932 why be worried about how efficient idling was?

    The hose also detaches for direct connection between exhaust and car window, convenient for those considering suicide due to economic conditions.
