A Launch Loop is a metal loop in an evacuated tube that spins at high speed on magnetic bearings. As it speeds up one side of the loop is projected up to a high altitude. Vehicles are electromagnetically accelerated on top of the tube up to orbital speeds and can be launched into low earth orbit or beyond.

For safety and astrodynamic reasons, launch loops would be located in the ocean near the equator, well away from habitation.
