"Within the next 10 years the USA must invest $1.5 trillion to overhaul elements of the aging electrical power grid, including adding 16,000 km of new transmission cable to integrate solar and wind power sources. Presently, 6.9% of the electrical energy transmitted into the U.S. power grid is lost as heat through resistive losses. The overall objective of this project is to develop higher conductivity and higher strength aluminum conductor wire for the new high voltage electrical power transmission system. If the strength of aluminum conductor alloys can be increased sufficiently by nanostructuring, then high conductivity nano-aluminum with conductivity over 58%IACS (%IACS is a measure of conductivity compared to copper, according to the International Annealed Copper Standard) can replace steel reinforcements with 8%IACS conductivity in the widely used Aluminum Conductor Steel Reinforced (ACSR) transmission cables. The net effect of replacing ACSR cables with nano-aluminum would be to nearly double the ampacity of the U.S. power grid, without adding any additional transmission towers or lines."
