Tesla's Latest Scheme

As noted in this week's patent record of the Western Electrician, a patent has been granted to Nikola Testa on the method of insulating conductors which consists in freezing water or other mixture by artificial means around the conductor to be insulated and maintaining the insulator in its frozen condition. Much has been said about the revolutionizing character of the invention by the daily press. Just how the system which requires the maintenance of a set of refrigerating plants along a transmission line is to be superior to present systems is not pointed out.
