Major automakers this fall will begin selling cars that produce at least 70% less pollution than vehicles now in showrooms. Under a plan approved by the Environmental Protection Agency, the new models will be sold in 12 states from Virginia to Maine. And, starting with 2001 models, manufacturers will sell the cleaner cars nationwide. Engineers are lowering the emissions in 1999 models by using new catalytic converters, air and fuel controls, and electronic technology. They will place converters in tail pipes as close as possible to the engine. Sensors in the exhaust stream will monitor continually the ratio in the combustion chamber. An optimum ratio of 14.7 parts air for every one part of fuel will be maintained automatically.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
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
