A new, lightweight, high-performance conductor reinforced with an aluminum matrix composite wire developed for overhead power cables should increase transmission capacity, reduce costs, and meet environmental goals. The composite conductor, a joint endeavor of 3M and Electricite de France (EDF), will span three development phases over four years. The composite wire, reinforced with 3M's patented Nextel ceramic fibers, has the potential to provide two to three times the strength-to-weight ratio of comparable steel wire, according to 3M's Warren E. Vollmar. He anticipates the wire will have four times the electrical conductivity and less than half the thermal expansion of its steel counterpart. "These conductors are being developed for use in reconductoring applications to increase ampacity by an anticipated 40 to 100%," Vollmar adds. Both 3M and EDF will fund its own development activities. FAX (612) 736-7149.
Being in an incubator can be analogous to shopping in a “big box retailer.” You can find many things you need under one roof along with moral support to sustain and move your startup to a successful launch.
Scientists at four major universities in Europe have released a joint paper describing the use of light to put active materials into motion and to control that motion, producing lifelike mechanisms that may or may not contain living organisms, but can produce useful work.
