DuPont of Wilmington, DE, spent 15 years developing a new category of bio-based materials called DuPont Renewably Sourced Materials. The company launched a Web portal at renewable.dupont.com to make it easy for design engineers to find and learn about these materials. In addition to basic product information, the website provides environmental data sheets for each product family. These sheets disclose information on the products’ cradle-to-grave environmental footprint, including an analysis of greenhouse gas emissions and non-renewable energy consumption.
DuPont’s renewably sourced materials are high-performance, bio-based materials and biofuels made in whole or in part from renewable agricultural feedstocks such as corn, soybeans, sugar cane and wheat rather than petroleum. In the future, DuPont expects to make these materials from cellulosic feedstocks from fast-growing energy crops such as grasses and agricultural byproducts like corn stalks. There are two criteria DuPont uses to select renewably sourced materials. First, they must contain at least 20 percent renewably sourced ingredients by weight, and second, the product must perform as well or better than petroleum-derived products.
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
