Military payment certificates, or MPC, was a form of currency used to pay United States (US) military personnel in certain foreign countries in the mid and late twentieth century. They were used in one area or another from a few months after the end of World War II until a few months after the end of U.S. participation in the Vietnam War – from 1946 until 1973.
The engineers of Hansa-Lloyd, having no experience with designing either armed or armored vehicles, came up with a big-wheel design which they called Treffas-Wagen. A single prototype was completed on February 1, 1917.
When the vehicle was subjected to thorough tests in February and March of 1917, many fundamental problems were encountered. The guns had such a powerful recoil that, after firing just a few shots, the gunner could not continue shooting due to significant head and shoulder pains, which raised grave concerns over the vehicles operational ability. Another issue was the center of gravity which was too far forward. When driving over a ditch, there was a high chance the vehicle would flip itself, which actually happened during a test in the summer of 1917. The vehicle dug itself in, got stuck, and eventually flipped itself over.
All issues combined, this vehicle had serious engineering problems caused by the design, which is not so strange given that this vehicle was one of the first of its type and the first armored vehicle designed by Hansa-Lloyd. On May 14, 1917, a demonstration was held which included the Sturmpanzerwagen A7V wooden mock-up, the Orion-Wagen, the Dür-Wagen, and the Treffas-Wagen. After these trials, the OHL (Oberste Heeres Leitung – Supreme Army Command) concluded that the Treffas was unfit for combat use and rejected the design.
Many expeditions to the “Unknown” ended gruesomely because they didn’t know and were not prepared; While going to these places today one has a very good chance to survive. I can only assume it will be the same with space explorations (once we’ll get there). The first trips will have extremely poor surviving rates but later you might as well go there with your class field trip.
The “Power Mower of the Future” is demonstrated in Port Washington, Wis., Oct 14, 1957. The lawnmower has a five foot diameter plastic sphere in which the rider sits on an air foam cushioned seat. It has its own electric generating system for operating running lights, a radio telephone, air conditioning and even a cooling system to provide a chilled drink on a hot day. It can be used for many purposes. It can mow the lawn, weed it, feed it, seed it, spray for insects, plow snow and haul equipment. It can even be used as a golf cart.
It may look better with one blue diagonal line instead of the current river like stripe. The emblem could be put in the middle if keeping its size, or put in the upper left side with smaller size
