A government-industry project to invent a practical battery for electric vehicles is trying to do too much too soon. So concludes a study by a committee of the National Research Council. The U.S. Advanced Battery Consortium (USABC) was formed in 1991 as an R&D project of the Department of Energy and the three major U.S. automakers. The purpose was to provide increased range and improved performance for electric vehicles "in the latter part of the 1990s." No technology has yet fully met even the midterm goals, the report says, because USABC had "an overly ambitious schedule imposed by regulatory requirements." (See "Nation's charge to electric cars stalls" in this issue.)

At the Design News webinar on June 27, learn all about aluminum extrusion: designing the right shape so it costs the least, is simplest to manufacture, and best fits the application's structural requirements.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
