Heated lattice tungsten filaments can emit more energy than solid tungsten filaments—a discovery that could meet the increasing power demand in advanced electrical applications such as hybrid electric cars—says an analysis by Technical Insights (www.technical-insights.frost.com). With crystalline regularity, tungsten lattices are capable of bending light without losing any energy, exhibiting a conversion efficiency of 34% and electrical power density of about 14 W/cm2 when heated to 1,250 centigrade. Thanks to computer chip production technology, they can now be mass-fabricated.
