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.
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.
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.
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.
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.
One of the biggest challenges that consumers and service providers will have in the future is maintaining a wide range of sensor and control devices located throughout the smart home. For ease of use and installation, it makes much more sense to have these powered by either batteries or by energy harvesting technologies.
For the past decade or more, as Al Gore and the majority of climate-change scientists have insisted that the world is speeding headlong toward an environmental catastrophe of epic proportions, European countries have adhered to stringent emission controls....
With the explosive growth of bandwidth demand in telecommunications networks, experts are continually seeking new ways to transmit increasingly large amounts of data in the quickest and cheapest ways possible. Photonic devices—which convert light to electricity and vice versa—offer an energy-efficient alternative to traditional copper network links for information transmission.
Being able to charge 30 electric cars at once requires ingenious energy management. Researchers are incorporating renewables into the design of a smart grid for Germany’s largest charging station. The network of charging stations for EVs is becoming more tightly meshed.
Colorful, see-through solar cells invented at the University of Michigan could one day be used to make stained-glass windows, decorations and even shades that turn the sun's energy into electricity. The cells, believed to be the first semi-transparent, colored photovoltaics, have the potential to vastly broaden the use of the energy source.
University of Cincinnati researchers are reporting early results on a way to make solar-powered panels in lights, calculators and roofs lighter, less expensive, more flexible (therefore less breakable) and more efficient. Fei Yu, a University of Cincinnati doctoral student, will present new findings on boosting the power conversion efficiency of polymer solar cells on March 3, at the American Physical Society Meeting in Denver.
Transducers USA (Elk Grove Village, IL) has introduced their new piezo ceramic MLCT (Multilayer Ceramic Transmitter) series. Its unique simple acoustic multi-layer ceramic construction produces a high output of 80 Db with only 16V low driving voltage.
Generating electricity is not the only way to turn sunlight into energy we can use on demand. In a study published last week in the journal Science, Choi and postdoctoral researcher Tae Woo Kim combined cheap, oxide-based materials to split water into hydrogen and oxygen gases using solar energy with a solar-to-hydrogen conversion efficiency of 1.7 percent, the highest reported for any oxide-based photoelectrode system.
Earlier this month, NJIT formalized an agreement with Chinese partners that will advance the university's research on thin-film solar cells, an alternative energy technology with the potential to make buildings and other infrastructure substantially more energy-efficient.
The University of Tennessee, Knoxville, will be part of a national effort, announced today by President Barack Obama, which could lead to more fuel-efficient cars and decreased costs for ships and aircraft. Suresh Babu and a team of faculty will help lead UT's research effort in the $140 million Detroit-based institute....
A study was recently released by North Carolina State University that provides evidence supporting the fact that electric drive vehicles (EDVs) have little impact on reducing emissions. As an engineering audience that knows efficiency when they see it, most PD&D readers will throw their hands in the air having known this for some time.
Class D is redefining the trade-offs in audio power amplifier design, simultaneously delivering smaller size and higher power density with better sound than Class AB audio systems. Class D also has the advantage of offering low distortion and more stable dynamic response....
Clean hydrogen power that's expected to lower emissions and reduce energy consumption will be coming to the Port of Honolulu in 2015 after the completion of a new fuel cell technology demonstration, one that could lead to a commercial technology for ports worldwide.
Soraa (Fremont, CA) announced today the world’s most efficient LED, which it will integrate into the market’s first full-visible-spectrum, large-form-factor lamps. Soraa’s third generation (Gen3) GaN on GaN LED achieves world-record setting wall-plug-efficiency, outperforming the nearest competitor by 20% at normal operating conditions.
Selecting a Chevy Volt, Tesla Model S, Nissan Leaf — or one of many other new models — shoppers in the United States bought more than 96,000 plug-in electric cars in 2013. That's a tiny slice of the auto market, but it's up eighty-four percent from the year before.
Drawing a link between reduced fuel consumption and climate change, President Barack Obama said Tuesday that his administration will issue tougher fuel-efficiency standards for delivery trucks by March 2016. Obama said helping these vehicles use less fuel would have the triple benefit of making the U.S. less dependent on imported oil....
Microchip Technology (Chandler, AZ) announced its next-generation family of energy-measurement Analog Front Ends (AFEs) with industry-leading accuracy. The MCP3913 and MCP3914 integrate six and eight 24-bit, delta-sigma Analog-to-Digital Converters (ADCs), respectively, with 94.5 dB SINAD....
