Abstract
Our scenario foresees an early phase of development of propulsion technologies with a 10 year period of manned mission definition studies, automated probe payload definition studies and development efforts on critical propulsion technology areas.
There is nothing neither so big nor so crazy that one out of a million technological societies may not feel itself driven to do, provided it is physically possible.
Freeman Dyson

Some important modern stellarator experiments are Wendelstein 7-X, in Germany, and the Large Helical Device, in Japan; (1) a tokamak is a device using a magnetic field to confine plasma in the shape of a torus. Important experiments are: Tore Supra, at the CEA, Cadarache, France in operation since 1988; FTU, in Frascati, Italy in operation since 1990; and Alcator C-Mod, MIT, Cambridge, USA in operation since 1992; (2) The National Ignition Facility, or NIF, is a large, laser-based inertial confinement fusion research device located at the Lawrence Livermore National Laboratory in Livermore, California.
