Ruppell Spacetrack is an air floating maglev track for lauching a spaceship. An elevator is used to lift the spaceship to 20 km high above the Earth's surface. A long track accelerating it at 3G is used to give the spaceship enough energy to exit Earth attraction.
Hygrogen ballons and a huge electric fan (not see on the drawing) are used to keep the track in the right position and also act as counterweight during the accelaration phase.
Electric and hydrogen supply are coming from the Earth to keep the hydrogen balloons filled and fan running.
All the cables are adjustable in length from the ground so the angle of exit can be change according to the target needed.
