The Chevy Volt gets 230 mpg? Wow. To me, that’s a really silly statement. How is the gas mileage of a plug-in electric car relevant? The real issues, of course, are the net impact on carbon dioxide emissions and the reliance on imported hydrocarbons. And there the picture for cars like the Volt is really fuzzy. Most of the energy for the Volt comes from the electric power grid. Forty-nine percent of electric power in the United States is generated from coal, which spews carbon dioxide and pollutants. About 7-8 percent of power is lost during transmission.
Cars like the Volt that will be charged in off-peak hours (overnight) in areas heavily reliant on hydro and nuclear power, such as the Toronto area or parts of California, will definitely be a major improvement over gas-powered cars,
But I haven’t seen a scientific third-party study that really lays out the facts on the real net contribution of electric vehicles. To announce that it achieves 230 mpg is silly and misleading.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
Researchers at the Missouri University of Science & Technology have designed a new nanoscale material that can transmit light faster than the 186,000 miles per second it usually takes to travel through air.
It has often been said that as California goes, so goes the nation. This spring, the state's wind power is setting energy generation records and solar energy generation is expected to rise sharply during the second half of 2013.
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
