HYLIION - HYBRID TECHNOLOGY FOR SEMI-TRAILERS AND THE TRUCKING INDUSTRY

Hyliion is bringing hybrid efficiency to the trucking industry by replacing a semi-trailer’s passive axle with the Intelligent Electric Drive Axle System. The system can decrease fuel consumption and reduce emissions by capturing wasted energy and storing it in a battery pack to help propel the trailer when needed. Currently, tractor-trailers get 6.5 miles per gallon, and on average use $48,000 of fuel annually (per tractor). The trucking industry in the U.S. spends $150B per year on fuel; 6.2% of all emissions in the U.S. comes from trucks.

DESOLENATOR — WATER FROM SUNSHINE

William Janssen, Desolenator, London, UK

The Desolenator is a water-purification technology that decontaminates water from any source using only solar energy. The technology is a very affordable ($0.005/L) “at-source” method of water purification. It offers a combination of features and capabilities that makes it extremely well suited for household use. It is GSM-mobile enabled and is data-driven through sensors, enabling service through micro mobile payment. It is eco-friendly, has a lifespan of up to 20 years, doesn’t require filters/ membranes, doesn’t drain the main’s electricity, and doesn’t expel toxic waste into the ocean. The long-term goal is to prevent the worsening of the water crisis.

Editor’s Choice: November 2016

A handheld laser torch for welding and brazing metals enables in-field repairs where space and time are constrained. The fiber laser torch incorporates changing lenses to allow the operator to adjust the laser’s power output in real time. Applications include engine repair, medical device manufacturing, plastic mold and die restoration, and jewelry manufacturing and repair. Find out more here.

Castrol, Oxford, UK

Castrol’s NEXCEL system is a sealed oil cell that contains both the engine oil and the oil filter, so it can be easily removed and replaced by hand in about 90 seconds versus 20 minutes for a conventional oil change. The sealed cell ensures that used oil is collected and handled safely, facilitating enhanced recycling and reuse of the waste oil into high-quality lubricants through a dedicated re-refining process.

New GASOMETER Design Uses Active Accommodation Offering Significant Improvements Vs. Liquid-sealed Methods

Active Accommodation means using a precision controlled and driven cylinder/piston assembly to collect and measure gas sample volumes without requiring energy to be extracted from the process that generates the gas. The mechanism uses lubricated O-Rings to seal the measuring chamber unlike classical Wet Test Meters that require a water or oil bath to produce an isolation seal.

The State of Earth

U.S. Senator Gaylord Nelson created Earth Day in 1970. Over the years, Earth Day grew in popularity and in 2009, the United Nations officially named April 22 as International Mother Earth Day. Earth Day (www.earthday.org) is now celebrated by over one billion people in nearly 200 countries.

Continental-Scale Mapping of Adélie Penguin Colonies from Landsat Imagery

Remote sensing is used for biological conservation.

Goddard Space Flight Center, Greenbelt, Maryland

The Adélie penguin has a circum-Antarctic distribution and is widely considered a useful indicator of status and change in the Antarctic and Southern Ocean ecosystems. Breeding distribution of the Adélie penguin was surveyed with Landsat-7 Enhanced Thematic Mapper Plus (ETM+) over the entire continent of Antarctica. An algorithm was designed to minimize radiometric noise and to retrieve Adélie penguin colony location and spatial extent from the ETM+ data. In all, 259 ETM+ scenes were selected from the Lansdat archive from the 1999–2003 era and were used in the retrieval. Pixel clustering identified a total of 244 individual Adélie penguin colonies, ranging in size from a single pixel (900 m2) to a maximum of 875 pixels (0.788 km2). The Landsat retrievals successfully located Adélie penguin colonies that accounted for ≈96 to 97% of the regional population used as ground truth, with errors of omission and commission on the order of only 1 to 2%.

Daily Mesoscale Sea Surface Salinity from Evaporation and Precipitation

This model leads to a method for deriving sea surface salinity from evaporation and precipitation data at improved resolution.

NASA’s Jet Propulsion Laboratory, Pasadena, California

Quantification of salinity is hampered by the lack of time and space resolution of existing measurements and models. At present, skin salinity measurements are available every few days with limited spatial resolution. Daily skin salinity products are full of gaps, which some applications can’t tolerate. Modeled salinity derived in the ocean mixed layer differs from remote sensing data of ocean skin layer salinity to a large extent for certain regions. The cool skin is a conductive layer in the upper few millimeters of the ocean within which transport of salt is dominated by vertical diffusion under the condition of weak to moderate winds. A technique to derive ocean skin layer salinity from satellite-based data for daily and 101 to 102 km scales was developed.
