Reform of energy subsidies in oil-exporting countries can reduce carbon emissions and add years to oil exports, according to a new paper from Rice Univ.’s Baker Institute for Public Policy. The paper reviews the record of energy-subsidy reforms and argues that big exporters should reduce energy demand by raising prices, and that this can be done without undermining legitimacy of governments that depend on subsidies for political support.
A new laboratory at the Wisconsin Energy Institute on the Univ. of Wisconsin-Madison campus will strengthen Johnson Controls' innovation capabilities as the company researches and develops next-generation technology. The partnership represents the kind of innovation Johnson Controls is developing to craft the next generation of market-leading energy storage technology.
Rice Univ. engineering students think it’s a shame to waste energy, especially in space. So a team of seniors invented a device that turns excess heat into electricity. Heat created by electronics onboard the International Space Station (ISS) now gets tossed overboard into the void. But new technology to turn heat into power would make it possible to put it back to work to run the myriad systems onboard.
A Rice Univ. laboratory has flexible, portable and wearable electronics in its sights with the creation of a thin film for energy storage. The laboratory developed a flexible material with nanoporous nickel-fluoride electrodes layered around a solid electrolyte to deliver battery-like supercapacitor performance that combines the best qualities of a high-energy battery and a high-powered supercapacitor without lithium.
Researchers at Oak Ridge National Laboratory have developed a new and unconventional battery chemistry aimed at producing batteries that last longer than previously thought possible. In a study published in the Journal of the American Chemical Society, ORNL researchers challenged a long-held assumption that a battery’s three main components can play only one role in the device.
The solar lamp developed by a start-up in Switzerland is a more effective, safer, and less expensive form of illumination than the traditional oil lamp currently used by more than one billion people in the world. Designed to be made by anyone, these solar-powered light-emitting diode lamps require nothing more than locally-found equipment. Only the solar panels are ordered from abroad.
Navigant Research forecasts that the “global biofuels production will reach 61 billion gallons by 2023, replacing nearly 6% of global transportation fuel production from fossil sources and generating $70 billion in new revenue over the next decade.” The demand for an appropriate crop that can provide biofuels, without competing for land use with food crops, is on.
It’s an obvious truism, but one that may soon be outdated: The problem with solar power is that sometimes the sun doesn’t shine. Now a team at Massachusetts Institute of Technology and Harvard Univ. has come up with an ingenious workaround: a material that can absorb the sun’s heat and store that energy in chemical form, ready to be released again on demand.
Research from North Carolina State Univ. reveals that solar cell efficiency is based upon a delicate balance between the size and purity of the interior layers, or domains. These findings may lead to better designs and improved performance in organic solar cells.
The Laboratory Design Conference is only a few days away, with registration ending on March 31st. Your opportunity to learn, network and participate in discussion about hot-button trends in laboratory design is coming to Boston, April 2-4th. The conference brings together recognized experts in the field with high-level users and lab facility owners, offering up-to-the-minute information that's vital in an evolving environment.
What research lab doesn’t care about a good return on investment for their spending? The last five years has marked an increase in the level of scrutiny applied to projects to assure maximum ROI. The early design process demands greater economic analysis of lifecycle costs to reduce operating and energy costs and optimize environmental performance.
Researchers have engineered a bacterium to synthesize pinene, a hydrocarbon produced by trees that could potentially replace high-energy fuels, such as JP-10, in missiles and other aerospace applications. With improvements in process efficiency, the biofuel could supplement limited supplies of petroleum-based JP-10, and might also facilitate development of a new generation of more powerful engines.
Imagine a computer so efficient that it can recycle its own waste heat to produce electricity. While such an idea may seem far-fetched today, significant progress has already been made to realize these devices. Researchers at the Univ. of Utah have fabricated spintronics-based thin film devices which do just that, converting even minute waste heat into useful electricity.
The demand for solar and wind power continues to skyrocket. Since 2009, global solar photovoltaic installations have increased about 40% a year on average, and the installed capacity of wind turbines has doubled. The dramatic growth of the wind and solar industries has led utilities to begin testing large-scale technologies capable of storing surplus clean electricity and delivering it on demand when sunlight and wind are in short supply.
Sandia National Laboratories engineers have been studying the most effective ways to use solar photovoltaic (PV) arrays—a clean, affordable and renewable way to keep the power on. Systems are relatively easy to install and have relatively small maintenance costs. They begin working immediately and can run unassisted for decades.
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.
A self-contained, waterless toilet, designed and built using a $777,000 grant from the Bill & Melinda Gates Foundation, has the capability of heating human waste enough to sterilize the waste and create biochar, a highly porous charcoal. The toilet, fueled by the sun, is being developed to help some of the 2.5 billion people around the world lacking safe and sustainable sanitation, and will be unveiled in India this month.
Over the first six months in their special, new, four-bedroom home in suburban Maryland, the Nisters, a prototypical family of four, earned about $40 by exporting 328 kW-h of electricity into the local grid, while meeting all of their varied energy needs. These virtual residents of the Net-Zero Energy Residential Test Facility (NZERTF) on the campus of NIST didn't have to skimp the creature comforts of 21st century living, either.
As energy costs rise, more Americans are turning to bioenergy to provide power to their homes and workplaces. Bioenergy is renewable energy made from organic sources, such as biomass. Technology has advanced enough that biomass power plants small enough to fit on a farm can be built at relatively low costs. Now, researchers have found that creating a bioenergy grid with these small plants could benefit people in rural areas.
Laboratory Design Newsletter features new laboratory construction, renovation and adaptive reuse projects in each issue and also online. The new projects section of the Website hosts a large variety of laboratory builds in academic, medical, private, commercial and government laboratories.
Despite their potential to reduce carbon dioxide emissions and fuel consumption, electric and hybrid cars and trucks struggled for years to find a solid customer base. Much of the reason came down to cost and convenience: Electric car batteries are expensive, and charging them requires plug-in infrastructure that’s still sparse in the U.S.
The wind has long been used as a metaphor for constant change, wayward and capricious. Wind turbine engineers deal with that changeability every day, along with a host of other challenging factors. Their products must operate in desert sandstorms and in corrosive salt water. The ambient temperature at the turbine site can be blisteringly high or numbingly frigid.
Massachusetts Institute of Technology chemists have devised a way to trap carbon dioxide and transform it into useful organic compounds, using a simple metal complex. More work is needed to understand and optimize the reaction, but one day this approach could offer an easy and inexpensive way to recapture some of the carbon dioxide emitted by vehicles and power plants.
The viability of the bioenergy crops industry could be strengthened by regulatory efforts to address nonpoint source pollution from agricultural sources. That, in turn, means that the industry should be strategic in developing metrics that measure the ability to enact positive changes in agricultural landscapes, particularly through second-generation perennial crops, according to a paper by a Univ. of Illinois expert in bioenergy law.
Tear apart an electric car's rechargeable battery and you'll find a mineral normally associated with No. 2 pencils. It's graphite. And experts say the promise of expanded uses for "pencil lead" in lithium-ion batteries, as well as a decrease in supply from China, has helped touch off the largest wave of mining projects in decades.
