The highly touted government-industry program to design a "supercar" may be concentrating on something few drivers will be able to afford or even want. So warns a committee of the National Research Council in its latest annual review of the Partnership for a New Generation of Vehicles (PNGV). Last year PNGV officials picked their best candidate for an affordable, mid-size vehicle that can get up to 80 mpg, yet meet prevailing emission standards. Their selection for a concept vehicle to be built in the year 2000 is an electric car that also has a small diesel engine. The committee's report, however, doubts that the proposed design will meet either the affordability or the emissions goal. It suggests lowering the target to 60 mpg. Hybrid-electric vehicles, it adds, would require complex and costly battery, power-conversion, and electronic-control systems. The panel further notes that nearly half the sales in the U.S. automotive market today is in sport utility vehicles, minivans, and light trucks. It proposes that PNGV also evaluate these vehicles.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
