The fundamental precepts regarding the design and applications of tethers in space are set forth with specific attention given to the problem of generating electrical power. An analysis is conducted concerning the establishment of effective electrical contact between the cable and the rarified ionosphere through which the tether travels. A solution is described that eliminates both the insulation covering the cable and the anode generally required for effective electrical generation. An essentially bidimensional or long cylindrical tether is shown to be the most effective shape since it capitalizes on the orbital-motion-limited regime. This regime effectively eliminates the magnetic effects and blocking effects that can impede the performance of electrodynamical tethers. The solution is shown to be an effective theoretical technique for creating good contact between the tether and a rarified ionosphere such as that of the earth or the large outer planets.
