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.
These free camps are designed for children ages 10 to 18. Attendees are introduced to 3D CAD software and shown how 3D printers can make their work a reality. Many classes were nearly 50 percent girls and 50 percent boys.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
