Major leaks from oil and gas pipelines have led to home evacuations, explosions, millions of dollars in lawsuit payouts and valuable natural resources escaping into the air, ground and water. But scientists say they have developed a new software-based method that finds leaks even when they’re small, which could help prevent serious incidents and save money for customers and industry.
German electronics and engineering company Siemens AG has reached a deal to acquire oilfield equipment maker Dresser-Rand for $7.6 billion. Dresser-Rand, based in Houston and Paris, has annual revenue of around $3 billion and employs about 8,100 people. Its portfolio of compressors, steam and gas turbines and engines is expected to complement Siemens' existing offerings in the gas, oil and power generation businesses.
During the six-day IMTS manufacturing technology show in Chicago this week, the “Strati” will be the first vehicle printed in one piece using direct digital manufacturing. The process will take more than 44 hours of print time. A team including Local Motors, Cincinnati Inc. and Oak Ridge National Laboratory will then rapidly assemble it for a historic first set for Saturday.
Coming to Nevada's high desert: A massive, $5 billion factory that will pump out high-tech batteries for hundreds of thousands of electric vehicles. That's assuming state leaders deliver on the economic incentives they packaged to entice Tesla Motors to Nevada rather than four other states competing for the factory and the economic jolt it promises to bring.
Advances in artificial intelligence and robotics mean that machines will soon be able to do many of the tasks of today's workers. But David Hummels, a professor of economics at Purdue Univ., says humans still have a unique advantage that machines may never be able to emulate: our ability to respond to other humans.
Life cycle engineering connects the engineers who grapple with the efficiencies of production processes, machine design, and process chains with the industrial ecologists who develop more over-arching methods of environmental assessment. In a recent issue of the Journal of Industrial Ecology, experts explore the latest research on sustainable manufacturing and how life cycle engineering is being used to reduce environmental impact.
A new survey released Wednesday by the Pew Research Center's Internet Project and Elon University's Imagining the Internet Center found that, when asked about the impact of artificial intelligence on jobs, nearly 1,900 experts and other respondents were divided over what to expect 11 years from now. Nearly as many people said robots would kill more jobs than they create as those who think they will create more jobs than they destroy.
Researchers have developed a new design for the framework of columns and beams that support bridges, called "bents," to improve performance for better resistance to earthquakes, less damage and faster on-site construction. The faster construction is achieved by pre-fabricating the columns and beams off-site and shipping them to the site, where they are erected and connected quickly.
Talk about a cosmic caffeine jolt. The International Space Station is getting a real Italian espresso machine. Astronauts of all nationalities have long grumbled about the tepid instant coffee served in pouches and drunk with straws 260 miles above Earth. The pouches and straws aren't going away, but at least the brew will pack some zero-gravity punch thanks to the ISSpresso, which can also make tea and consommé.
New robot guides at a Tokyo museum look so eerily human and speak so smoothly they almost outdo people. The two life-size robots, which have silicon skin, artificial muscles, and can speak in a variety of voices, will be on display starting Wednesday, allowing the public to interact with them extensively.
Tesla CEO Elon Musk promised Thursday to give away the company's entire patent portfolio to all comers, as long as they promised not to engage courtroom battles over intellectual property. The decision is meant to encourage other automakers to expand beyond gasoline-burning automobiles, and opens the door to more collaboration with Tesla, which is already making electric systems for Daimler and Toyota.
HorseFly has eight rotors, a wirelessly recharging battery and a mission to deliver merchandise right to your doorstep. The new drone is the result of collaborative efforts by the Univ. of Cincinnati and AMP Electric Vehicles makers of the WorkHorse all-electric delivery truck. The newly designed, autonomous unmanned aerial vehicle was developed to work in tandem with AMP's delivery trucks to deliver packages in an efficient way.
The skies off the Hawaiian island of Kauai will be a stand-in for Mars as NASA prepares to launch a saucer-shaped vehicle in an experimental flight designed to land heavy loads on the red planet. For decades, robotic landers and rovers have hitched a ride to Earth's planetary neighbor using the same parachute design, but NASA needs a bigger and stronger parachute if it wants to send astronauts there.
The SuperDraco thruster, an engine that will power SpaceX’s Dragon spacecraft to orbit, has completed a test regimen held over the last month at SpaceX’s Rocket Development Facility in Texas. This qualification test involves a variety of conditions conditions including multiple starts, extended firing durations and extreme off-nominal propellant flow and temperatures.
According to new research from Sweden, two aircraft engine concepts, a geared turbofan and an open rotor, can enable a significant reduction to aircraft fuel consumption. With an open rotor, the potential reduction is 15%. An open rotor engine generates most of the thrust from two counter-rotating propellers instead of a ducted fan. This enables a larger engine diameter and a higher propulsive efficiency.
In a typical wind farm, the wind turbine located in the wakes of upstream turbines would experience a much different surface wind compared to the ones located upwind due to wake interferences. Scientists at Iowa State Univ. have completed a study on the effects of these relative rotation directions, using two tandem wind turbines as a model. They found a big difference in performance between co-rotating and counter-rotating turbines.
Although lubricants for machinery are widely used, almost no fundamental innovations for this type of product has been made in the last 20 years, according researchers in Germany who have been working on a new class of lubricating substance. Their new liquid crystalline lubricant enable nearly frictionless sliding because although it is a liquid, the molecules display directional properties like crystals do.
Pipes, rails, and wires are typically manufactured at high speeds, which makes in-line inspection efforts difficult. This is because micro-defects take time to detect, even with machine vision technology. A new optical inspection system developed in Germany reviews the workpieces at 10 m per second, as fast as an Olympic sprinter, and finds defects in real time that can be as narrow as a single hair.
Industrial plants must function effectively. Remedying production downtimes and breakdowns is an expensive and time consuming business. That is why companies collect data to evaluate how their facilities are doing. At the Hannover Messe Digital Factory, held April 7-11, researchers in Germany will show how operators can analyze these huge amounts of data and use it as an early warning system when problems threaten.
Small wind turbines tend to be located in areas where wind conditions are more unfavorable and control systems of current wind turbines cannot adapt. To address this problem, researchers in Spain have developed an adaptive algorithm that can contribute toward making these miniature turbines more efficient.
For the past 100 years, the way your fridge preserved your food has been rooted in technology dating back to the mid-1800s, but that is about to change. GE researchers are developing a new magnetic refrigeration method that uses no refrigerants or compressors and is 20% more efficient than what is used today.
Additive manufacturing, or 3-D printing, offers a compelling alternative to more traditional manufacturing approaches at NASA, where the need for highly customized spacecraft and instrument components is quite high. The agency has recently launched a number of formal programs to prototype new 3-D printed components, including rocket engine injectors, and 3-D printers for use in space.
Stratasys, a manufacturer of 3-D printers and materials for personal use, prototyping and production, has announced the launch of the ground-breaking Objet500 Connex3 Color Multi-material 3-D Printer, the first and only 3-D printer to combine colors with a variety of photopolymer 3-D printed materials.
According to Anupam Agrawal, a professor of business administration at the Univ. of Illinois, Urbana-Champaign, firms can manage their sourcing better by developing relationships not only with their suppliers but also with their suppliers’ suppliers. The lack of communication or collaboration between the big players at either end of the supply chain spectrum can prevent gains in efficiencies.
Ultra-short laser pulses provide a fast and precise way of processing a wide range of materials without excessive heat input. Scientists from Bosch, TRUMPF, Jena Univ. and Fraunhofer Institute in Germany have turned the ultra-short pulse laser into an effective series-production tool. This type of laser can remove, or ablate, tiny areas measuring just a few nanometers.
A new device transforms almost any bicycle into an electric-hybrid vehicle using an app on a smartphone. The device, called the Copenhagen Wheel, is is equipped with wireless connectivity to track travel and installed as part of a rear hub of a bike wheel. Packed with a proprietary computer, batteries, and sensors that monitor how hard a rider is pedaling, it activates an onboard motor whenever support is needed.
