Skrew-Doo? - Neatorama

Ok here's something I've never seen before that dates back to pre-World War II. This contraption consists of a tractor and some form of corkscrew drive system. After a bit of research, it appears that this invention originates from Russia. Call it Russian mechanized genius/madness, you decide. Via - LiveLeak

For game geeks, a similar system was used for a giant tank in "Metal Gear Solid: Snake Eater" by a Russian bad guy. I thought the design was cool then, but neverbelieved it would actually work !

only problem is you cant go on uncuttable surfaces like pavement, but i guess if you have 4' of snow, that will never be a problem.
make the screws water tight and it was be a boat too

There was an episode of Junkyard Wars once where one team built one of these, but it didn't work because the rigged the screws to rotate the wrong way.

Did anybody else think that this was abandoned because of the danger of falling onto the spinning screws? That would tear you apart!
