Energy crop producer Ceres Inc. plans to market its new agricultural seeds and traits under the trade name Blade Energy Crops in the U.S. The first products to be sold under the brand are currently being multiplied for spring 2009 sowing. They include switchgrass cultivars developed specifically for biofuels, EG 1101 and EG 1102, as well as high-biomass types of sorghum.
Because of their high yields, energy crops can produce more fuel per acre than first-generation biofuel crops and further mitigate greenhouse gas emissions since the new crops require fewer inputs and actually build new topsoil. Ethanol made from switchgrass produces 90 percent less greenhouse gas emissions than petroleum and nearly five times more net energy than starch-based ethanol. Further improvements are likely as breeders introduce new seed varieties and innovations in refining technology are commercialized.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
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.
