Sales of electric vehicles (EVs) nearly doubled in 2013, but most won't take you farther than 100 miles on one charge. To boost their range toward a tantalizing 300 miles or more, researchers are reporting new progress on a "breathing" battery that has the potential to one day replace the lithium-ion technology of today's EVs.
Texas Instruments introduced two flyback power solutions that are said to achieve the highest energy efficiency and lowest standby power consumption for 5-W to 100-W AC/DC power supplies. The UCC28910 switcher with integrated
A nuclear waste repository must seal in radioactive waste safely for one million years. Researchers currently have to study them and their processes in real underground laboratories but a virtual underground laboratory will soon simplify their work.
As the United States continues to lead the world in the production of natural gas, scientists from the Florida campus of The Scripps Research Institute (TSRI) have devised a new and more efficient method with the potential to convert the major components found in natural gas into useable fuels and chemicals—opening the door to cheaper, more abundant energy and materials with much lower emissions.
America's current energy boom may take a new direction thanks to the discovery of a new way to turn raw natural gas into upgraded liquid alcohol fuel. In the March 14 issue of Science magazine, chemists from Brigham Young University and The Scripps Research Institute detail a process that could reduce dependence on petroleum.
Mornsun has launched the IF/B_XT-1WR2, F/B_XT-2WR2, F_D-1WR2, R2 series of DC-DC converters. Compared with the old generation, they have improved on efficiency, no-load power consumption, and short-circuit protection. They also feature compact size....
Micrel (San Jose, CA) announced that it would be previewing the MIC2111 DC/DC multi-mode controller at the Applied Power Electronics Conference and Exposition, APEC 2014. The industry conference will be held March 16-20, at the Fort Worth Convention Center.
The Energy Department’s National Renewable Energy Laboratory (NREL) has developed a web-based tool to help consumers better understand the energy performance of building-related products. The Technology Performance Exchange™ (TPEx™) is a portal that helps manufacturers and other organizations that measure and test products easily share performance data with product consumers.
GIGAVAC (Santa Barbara, CA) announced two additions to its High Voltage Contactor line of advanced switching solutions. The HX21 and HX200 join the HX22 as the smallest UL508 recognized contactors for high current switching at 1000 VDC, according to the company. The series can
Who needs a gun when you have CUPID? And by Cupid, I don’t mean that fat cherub that comes out around February 14th to shoot people with arrows — though the shooting part isn’t that far off. This CUPID, which stands for Chaotic Unmanned Personal Intercept Drone, is actually a personal security safety UAV.
Infineon Technologies AG (Neubiberg, Germany) is launching a high-precision current sensor, which requires only a sixth of the board space taken up by existing sensors on the market today, according to the company. Using the TLI4970, it is possible to measure
Vishay Intertechnology, Inc. (Malvern, PA) expanded its microBUCK family of integrated synchronous buck regulators with a new 4 A device offering high programmable switching frequencies of up to 1.5 MHz and a wide input voltage range of 4.5 V to 15 V. The high switching frequencies
Elsevier, a world-leading provider of scientific, technical, and medical information products and services, is pleased to announce that they have entered into a publishing agreement with the Energy Institute (EI) to publish its official journal, Journal of the Energy Institute. Journal of the Energy Institute, a peer-reviewed quarterly publication first published in 1926, is...
A new £20 million three-year programme that will support research to develop new low carbon manufacturing processes and technologies, low carbon cities and offshore renewables in the UK and China was agreed yesterday, Wednesday 5th March 2014.
There’s promising news from the front on efforts to produce fuels through artificial photosynthesis. A new study by Berkeley Lab researchers at the Joint Center for Artificial Photosynthesis (JCAP) shows that nearly 90-percent of the electrons generated by a hybrid material designed to store solar energy in hydrogen are being stored in the target hydrogen molecules.
Vertimass LLC, a California-based start-up company, has licensed an Oak Ridge National Laboratory technology that directly converts ethanol into a hydrocarbon blend-stock for use in transportation fuels. The ORNL technology offers a new pathway to biomass-derived renewable fuels that can lower greenhouse gas emissions and decrease U.S. reliance on foreign sources of oil.
