The fully integrated electro-hydraulic system is widely scalable. It comprises a broad range of vane and piston pumps, filters, frequency inverters, control and switch gear as well as Eaton’s innovative SmartWire-DT intelligent wiring technology. Combining the power density and proven performance of Eaton’s pump systems with the smart control functionality of VSDs, th...
Mayor Eric Garcetti on Wednesday unveiled an ambitious plan to make LA the most sustainable big city in the U.S. over the next two decades, a place where people ride bikes, board buses and trains, and even walk to get around. Drinking water would come from local sources instead of faraway imports. Solar panels would glimmer from rooftops like the lights at a Hollywood...
Connecticut-based FuelCell Energy built both power plants. Between them, they will meet almost the entire factory’s energy needs, with an on-site solar array providing more energy during peak hours of power usage. The two power plants replace grid power that would have led to the emission of more than 9,400 tons of CO2. Fuel cells produce power electrochemically, a...
Brynsengfaret School in Oslo will be built under a contract valued at SEK270m (£21m). The 11,700m2 school will be for grades one to seven and will include an auditorium with space for 840 pupils. The school’s ambitious environmental profile is intended to make the building a reference project for future schools in Norway and other countries. It will be built as a pass...
WASHINGTON, D.C., February 11, 2015 -- Scientists are using biology to improve the properties of lithium ion batteries. Researchers at the University of Maryland, Baltimore County (UMBC) have isolated a peptide, a type of biological molecule, which binds strongly to lithium manganese nickel oxide (LMNO), a material that can be used to make the cathode in high performance...
Doctoral student Joseph Carr developed the system with his adviser, Juan Balda, University Professor and head of the department of electrical engineering. Innovations in this field are critical as the U.S. moves toward integration of renewable energy sources to the national power grid. The U.S. Department of Energy pursued and was granted a U.S. patent for the tech...
Our energy system is going through a revolution. What type of energies will replace nuclear power? Will there be a rise in electricity prices? Will the hydrogen car become a part of everyday life in 2050? The Energy Center at EPFL, in collaboration with public partners, has developed an information portal, transparent and accessible to all, to understand the issues relat...
This morning I saw three articles that introduced the Windwheel, an architectural marvel that may be built in Rotterdam, Netherlands. While everyone is fascinated by its appearance (hey - I am too), the engineer in me wondered about the feasibility of its wind energy production. The Windwheel promises to be a stunning piece of architecture, featuring apartments, rotat...
That’s because many water systems use electric pumps to move water from an aquifer or reservoir to its customers. Putting a hydroelectric generator in the pipes would take energy away from the flow, so you’d need a more powerful pump to move the water. Thanks to the third law of thermodynamics, you’d lose more electricity with the larger pump than you would generate wit...
In its REForCh research program — "Resource-Efficient Forging Process Chain for Complicated High-Duty Parts" — IPH concluded it can reduce the burr percentage of forged crankshafts from 54% to 7%, saving approximately 20% of energy requirements in the process. IPH noted industrial-scale tests of the process have been successful, setting the stage for commercial applic...
Electrical theory has brought us the computer revolution, among other advances, because scientists and engineers figured out how to automatically control the flow of electricity based on varying conditions. Improvements in electronic technology continue to give us products that were merely imagined in sci-fi movies just a few decades ago. At the same time, the field o...
The challenge, of course, is doing all that while maintaining the Camaro’s status as a high-performance muscle car. How many ways do I love this idea? First, you know I’m a proponent of renewable energy, so hybrid-electric cars play a big role in a green energy future. Second, I’m an educator with a strong belief in project-based learning. A competition like this puts...
RWE Innogy said it hoped to make an announcement in the spring on the future of the 340MW windfarm, despite announcing two months ago it would not continue with the project. The company is in talks with several potential partners to build the windfarm. It is still working with Galloper’s joint owner Scottish and Southern Energy (SSE) that announced in March it woul...
Power and automation specialist ABB has been awarded a contract by Atlantis Resources to provide the onshore grid connection for phase one of the MeyGen tidal stream project in Scotland’s Pentland Firth. According to ABB, this project is at the forefront of world marine energy development and will harvest the tidal resources of one of the most energetic maritime sites...
AvaLAN to offer their thousands of IoT deployments a solution for remotely powering devices Madison, AL – AvaLAN Wireless, leaders in secure, fail-proof wireless connectivity, today announced the availability of their new remote solar power kits. These Remote Power Kits are designed for applications where power is needed but unavailable. “The AvaLAN Wireless Remote...
Recycling fracturing fluids is big business, but ridding water of dissolved solids is expensive and generates a waste stream of its own. Brackish water is often found in the salt-laden formations bordering gas reservoirs, and can be used for some wells. An ongoing problem, however, is the growing competition for water sources. Agriculture and energy producers are alre...
The Watts Bar Unit 2 nuclear reactor in Tennessee is slated to join the fleet in December 2015, but with only four other new nuclear power plants in the works, the industry needs to keep existing facilities operating longer to ensure uninterrupted electricity supply throughout the U.S. The U.S. Nuclear Regulatory Commission (NRC) originally licensed reactors to operat...
A technology innovation, however, purports to tackle these technological challenges head on and add more utility. Dubbed the Sunflower, the high concentration photovoltaic thermal (HCPVT) solar technology system from Airlight Energy borrows from existing and established technologies to create a hybrid system that can generate electricity at high conversion rates, capt...
A number of companies shy away from building wind-powered systems in northern regions, even though the wind blows with great power there. To begin with, weather conditions represent a Herculean challenge: Aerodynamic properties deteriorate when an ice layer forms on the rotor blades as temperatures drop to the below-zero range under freezing storm conditions. The turbine...
Researchers at the Fraunhofer Institute of Optronics, System Technologies and Image Exploitation IOSB in Ilmenau are developing information technology to make water power generation systems more efficient. The Advanced System Technology (AST) department is creating simulation and optimization models that consolidate external factors such as weather data, water levels and...
Let’s face it: Overhead transmission lines are not always accepted by the public. For various reasons, many people do not really like these highways of electricity. For one, they are not the prettiest of sights on the horizon. As they march across mountains, pile across prairies, dash through deserts – all in the service of transmitting power from generating stations ...
