In order to overcome the problem of overheat and enhance efficiency of electric wire, a special wire, figure 1, is invented. The special wire, figure 1, is made with vacuum sections, 13, and containing a middle wire, 12. The middle wire 12, could be silver or other high conductance materials. Vacuum sections, 13, reduce heat and thereby efficiency is enhanced. Nodes, 14, improve strength and ease application. The special wire, figure 1, should be used, at where absolute safety and high efficiency are major concerns.
