§ Tethers in vacuum

Tethers are a general topic area with multiple applications for propulsion and electricity generation. In the future, the PERMANENT website will discuss these concepts further. In the mean time, here are some links:

Tethers Unlimited, Inc., performs R&D on tethers. See

A 1999 Scientific American article covers R&D to that point in time, at (Robert L. Forward and Robert P. Hoyt)

§ Laser launch from Earth

The fundamental concept is a vehicle using the air around it for propulsion rather than carrying all its fuel with it, and getting the energy from a ground-based laser.

More information can be found by following leads in a 1999 Scientific American article at

The Lightcraft Technology Demonstrator website of the Air Force Research Lab is at

A few keywords used in association with this work are: "lightcraft", "laser propulsion" and "microsatellites". Current research is for propulsion of very small objects. > Transportation > Vehicles - Longterm
