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:

Great video of cooped up dolphins blowing underwater bubble rings to pass the time. Before we get all out of sorts that this is some sort of compulsive, depressive behavior from being locked up, note that this been observed in the wild as well.
Here's the thing: Shauna Theel has a video on the Polar Vortex vs. Rush Limbaugh:
Published on Jan 9, 2014
The term "Polar Vortex" was thrown around a lot last year, in reference to the persistent mass of very cold air that enveloped much of southern Canada and the US.
Everyone laughed ... earlier today ... when Rush Limbaugh claimed that the Polar Vortex, the ginormous weather phenomenon that brought so much cold to Canada and the United States over the last few days, was created by Liberals.
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.
Eat your heart out Bombadier - you weren't first ;)
That poor horse!!!
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!
