Quantum Space-time Door

The Quantum Space-time Door is an invention that was successfully built by Tony Flansaas as a way to increase storage and gain access to any location. It was built before the BattleMech.

History
After watching an episode of Enterprise, Tony reversed the polarity of one of his previous inventions to allow instant teleportation to any point in the universe. This was useful, as he recently acquired an abandoned Missile Silo in Colorado.
