Maglev: A New Approach
The Inductrack promises a safer, cheaper system for magnetically levitating trains. The same technology can also be used to launch rockets

Flywheels
Advances in materials and mechanical design make it possible to use giant flywheels for the storage of energy in electric-power systems and smaller ones for the propulsion of automobiles, trucks and buses

Progress toward Fusion Power
The controlled release of thermonuclear energy requires solving the problem of confining a hot plasma of electrons and positive ions. The problem is slowly yielding to analysis and experiment

Fusion Power
If man can tame the reactions in which the nuclei of atoms are fused rather than split, he will have an almost limitless source of energy. The problem is now being attacked in laboratories all over the world
