The Seventh Simple Machine: A New Kind of Mechanics
For thousands of years, we have used the six simple machines to shape our environment. In the last two hundred years, we’ve combined the simple machines to create complex mechanical devices: clocks, orreries, automobiles, merry-go-rounds.
Did we miss something? Are there things we can’t build with the six simple machines?
Tonight, we will look for the seventh simple machine.
i dont think that a plane is a simple machine.

If the 7th simple machine is The Plane, I suggest that the 8th is The Memory
Yes there is a seventh machine it is the plane.
Yes there is a seventh machine. It is the plane.

Check out http://particularconcepts.com. It resurrects a "new" (patented) seventh simple machine probably used by the Ancient Egyptians to move and erect granite Obelisks. School marmish, but fun.
