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.
Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
New sensor technology integrates sensors, traces, and electronics into a smart fabric for wearables that measures more dimensions -- force, location, size, twist, bend, stretch, and motion -- and displays data in 3D maps.
As we saw on the show floor this week at the Pacific Design & Manufacturing and co-located events in Anaheim, Calif., 3D printing is contributing to distributed manufacturing and being reinvented by engineers for their own needs. Meanwhile, new fasteners are appearing for wearable consumer and medical devices and Baxter Robot has another software upgrade.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
