On the Possibility of Extracting Energy from Gravitational Systems by Navigating Space Vehicles

This report describes a number of problems, generally involving the possibility of using reserved kinetic energy in such a way as to acquire, by suitable near collisions with one or the other of the celestial bodies discussed, much more kinetic energy that it possesses -- more by an order of magnitude than the available reserve energy would allow it to acquire by itself.

Pressure Balance in a Toroidal Pinch (open access)

Pressure Balance in a Toroidal Pinch

Abstract: In the study of a linear pinch, use of the equation of pressure balance has proven to be a powerful method of analyzing data taken with a magnetic probe. The toroidal pinch, however, is a geometrically more complicated object, and the use of the pressure balance equations is not so clean cut. It is the object of this note to analyze the pressure balance equations for a torus to the point where they might prove useful in interpreting probe data.

Design and Feasibility Study of a Pebble Bed Reactor-Steam Power Plant (open access)

Design and Feasibility Study of a Pebble Bed Reactor-Steam Power Plant

Originally issued as S and P 1963A, Parts I and II. This report covers a design and feasibility study of a pebble bed reactor-steam power plant of 125 megawatt electrical output. The reactor design which evolved from this study is a two-region thermal breeder, operating on the uranium-thorium cycle, in which all core structural materials are graphite. Fuel is in the form of unclad spherical elements of graphite, containing fissile and fertile material. The primary loop consists of the reactor plus three steam generators and blowers in parallel. Plant design and system analysis including cost analysis and capital cost summary are given.
