Modern Mechanix posted a neat article from the November 1933 issue of Popular Science about a man's design for an amphibious unicycle tank. The tank bears a striking similarity to Kerry McLean's Rocket Roadster whose project is profiled in the MAKE: book, Makers: All Kinds of People Making Amazing Things In Garages, Basements, and Backyards by Bob Parks.
From the 1933 Popular Science article:
UPDATE: BB reader Mykle Hoban writes, "The Museum of Retro Technology has a MASSIVE collection of pictures and history of various contrivances throughout the earlier days of the machine age (including) a whole section devoted to monowheels." Link
UPDATE: Thanks to the many many many South Park fans who point out that in the episode The Entity, Mr. Garrison invented his own monowheel called IT. Link
From the 1933 Popular Science article:
One of the oddest features of the revolutionary machine is formed by the steel-tube crutches that project ahead on either side like medieval lances. As the tank rushes upon a trench or obstruction, the operator will drop the tubes so they dig into the earth and the whole machine will vault through the air to the other side. An open-type form of the vehicle, which is shown on our cover, has also been devised by the inventor. Without the armored body or the crutches, it is designed for highway use.Link to Modern Mechanix, Link to Kerry McLean's site, Link to buy Makers: All Kinds of People Making Amazing Things In Garages, Basements, and Backyards (via MAKE: Blog)
