Abstract: A vacuum highway seal provides an effective barrier for maintaining a separation between the atmosphere and a vacuum highway, which allows vehicles to reach near orbital speeds on the surface of the earth. The vacuum highway seal is composed of a pool of water with a pipe extending from several feet below the surface to approximately forty feet above the surface of the water. Water is pushed by atmospheric pressure from the pool to approximately thirty two feet above the pool into the pipe. A vehicle is loaded with cargo and/or people at the dock in the pool, then is submerged and travels to the entrance of the pipe underneath the water. The pipe is tapered and sloped to allow an easy transition from the pool into the vacuum highway. As the water ballast used to submerge the vehicle is expelled the vehicle is accelerated to the surface of the water and the vacuum highway beyond. Once in the vacuum highway a second propulsion system is used to propel and lift the vehicle.
