How come we don’t all have one of these? I suppose one possible down side would be that if you fell off it would drag you into the vortex and crush you. But still … well, have a look:

    The real downside of the screwdrive was the limited maximum speed and weight possible, as opposed to tracked vehicles – still, it never died out completely. The U.S. Army developed a screwdriven vehicle for use in swampy areas in Vietnam, and screwdriven tractors are used in parts of Russia. Technically, it’s the only method of driving a vehicle that works on absolutely any surface (even water), although at hugely different degrees of effectiveness.

    Replacing horses and oxen with a machine? Sound like madness to me. Consumerism out of control! Next you will want a mechanical wood chopping machine so you can heat your home without doing any work.

    Elegant. As Phillip IV points out, speed and weight is rather limited, but the simplicity and ability to operate on pretty much any surface is quite impressive.

    I wonder if screwdriven vehicles are being used for “snow trains”? Seems like a pretty perfect application. Anyone at McMurdo Station out there?

    What impressed me the most was that the operator was wearing a tie. Good form!
