One-phase high-tension power transmission

The recent advance in Europe of the Thury direct-current system of power transmission demonstrates the fact that unless an alternating-current system approaching it in simplicity of design and economy of material is developed, it is only a question of time before the high-tension direct current will gain a footing upon this continent. Consequently, the writer proposes a high-tension one-phase system having several desirable features not in common with either the direct-current or the three-phase system.
