What kind of thinking do you do when you design products? An exhibition that opens this month in Washington attempts to answer the question. Called "Breaking Through: The Creative Engineer," the exhibition features case studies of modern engineering innovation. Arrays of interactive displays for all ages are designed to help tell the stories. The exhibition opens at the National Building Museum during National Engineers Week, February 22 to 28, and continues through November 8, 1998. A coalition of major engineering societies and American firms support the exhibition. Admission is free. For details, including show hours, check the museum Web site at http://www.nbm.org or phone (202) 272-2448.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
