Saliva-powered micro-sized microbial fuel cells can produce minute amounts of energy sufficient to run on-chip applications, according to an international team of engineers.
They need warmth to grow, but algae don’t necessarily need light. Experts in Finland, where warmer weather is rare, say it makes sense to link algae cultivation to industrial operations where residual heat is available to heat algae cultivation ponds or reactors. Recent research there shows that such an approach could be profitably implemented.
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.
The rotor and mast of a wind turbine can oscillate and this plays a big role in equipment development and maintenance. Up to now, this analysis has only been possible at discrete points located directly on equipment. Engineers are now using modern information technology to remotely measure the oscillatory pattern over the entire structure of the facility from several hundred meters away.
For 15 years trucks have been hauling decades worth of plutonium-contaminated waste to what is supposed to be a safe and final resting place a half mile underground in the salt beds of the Permian Basin in New Mexico. But back-to-back accidents and an above-ground radiation release shuttered the government's only deep underground nuclear waste dump and raised questions about the $5-billion-a-year program for cleaning up legacy waste.
Panasonic Corp. is considering setting up a new plant jointly with Tesla Motors Inc. in the United States to make lithium-ion batteries for electric vehicles. The Japanese electronics maker is mulling asking Japanese materials makers to set up bases at the new plant to create integrated production of batteries and is also considering supplying batteries to Toyota.
A new study from the International Electrotechnical Commission and the Fraunhofer Institute in Europe has found that nanotechnology will bring significant benefits to the energy sector, especially to energy storage and solar energy. Improved materials efficiency and reduced manufacturing costs are just two of the real economic benefits that nanotechnology already brings these fields and that’s only the beginning.
A multi-institutional team reports that it can increase sugarcane’s geographic range, boost its photosynthetic rate by 30% and turn it into an oil-producing crop for biodiesel production. These are only the first steps in a bigger initiative that will turn the highly productive sugarcane and sorghum crop plants into even more productive, oil-generating plants.
The Ivanpah Solar Electric Generating System, which sprawls across roughly 5 square miles of federal land near the California-Nevada border, formally opened on Feb. 13 after years of regulatory and legal tangles ranging from relocating protected tortoises to assessing the impact on Mojave milkweed and other plants. The plant, the world’s largest of its type, will test a balance between conservation and green energy growth.
Global gas manufacturer and supplier Matheson Tri-Gas Inc. has completed the acquisition of Continental Carbonic Products Inc., an Illinois-based manufacturer and supplier of dry ice and liquid carbon dioxide. Continental Carbonic Products is the largest independent supplier of dry ice in the U.S. and will strengthen Matheson’s North American business.
Instrumentation company FEI has acquired Lithicon AS of Trondheim, Norway, and Canberra, Australia. Lithicon provides digital rock technology services and pore-scale micro computed tomography (µCT, or microCT) equipment to oil and gas companies worldwide. In conjunction with the acquisition, FEI has obtained the helical scan microCT product and associated software from the Australia National Univ.
According to a study by Pacific Northwest National Laboratory, China can build its way to a more energy efficient future by improving the rules regulating these structures like houses, apartments and retail stores. The scientists created a unique model that projects how much energy can be saved with changes to China's building energy codes, and those savings were significant.
Construction on a new energy research facility at Pacific Northwest National Laboratory (PNNL) will start this April. The project, valued at approximately $10 million, will build a facility that will house a broad variety of energy research and PNNL's campus sustainability program. Research there will focus on power grid reliability and resiliency, integration of renewable energy onto the grid and reducing energy use in buildings.
What do champion surfers who gathered at last week’s Mavericks Invitational have in common with a Univ. of California, Berkeley engineer? They all are looking to harness the power of big ocean waves. But the similarities end there. For assistant professor Reza Alam, an expert in wave mechanics, the seafloor “carpet” he is proposing will convert ocean waves into usable energy.
Wind energy experts have completed a comprehensive study to understand how wind power technology can assist the power grid by controlling the active power output being placed onto the system. They find that wind power can do this by adjusting its power output to enhance system reliability, using forms of active power control such as synthetic inertial control, primary frequency control and automatic generation control regulation.
Installation of electric vehicle charging ports at some companies has not kept pace with soaring demand, creating thorny etiquette issues in the workplace. The shortage has created incidents of "charge rage" among drivers, with vehicles being unplugged while charging. But adding chargers is expensive.
Aircraft maker Boeing Co., Etihad Airways, the oil company Total and others say they will work together on a program to develop an aviation biofuel industry in the United Arab Emirates. Etihad ran a 45-minute demonstration flight Saturday in a Boeing 777 partially powered by aviation biofuel produced in the UAE.
By replacing platinum with molybdenum in photoelectrochemical cells, scientists from two Swiss labs have developed a cheaper and scalable technique that can greatly improve hydrogen production through water splitting as a means of storing solar energy.
America's newest, most expensive coal-fired power plant is hailed as one of the cleanest on the planet, thanks to government-backed technology that removes carbon dioxide and keeps it out of the atmosphere. But once the carbon is stripped away, it will be used to do something that is not so green at all. It will extract oil.
For millions of homes, plants, wood and other types of “biomass” serve as an essential source of fuel, especially in developing countries, but their mercury content has raised flags among environmentalists and researchers. Scientists are now reporting that among dozens of sources of biomass, processed pellets burned under realistic conditions in China emit relatively low levels of the potentially harmful substance.
Researchers in Lyon, a French city famed for its cuisine, have discovered a quick-cook recipe for copious volumes of hydrogen that involves water, rock, aluminum oxide and extreme pressure. The breakthrough suggests a better way of producing the hydrogen that propels rockets and energizes battery-like fuel cells.
The solar panel installer SolarCity is beginning to address one of solar power's big drawbacks: The sun doesn't always shine. The solution: big battery packs that will provide backup power while lowering electric bills. The supplier: electric car maker Tesla Motors, whose CEO Elon Musk is also the chairman of SolarCity.
Scientists at The Univ. of Texas at Austin have developed a new method to estimate gas production from hydraulically fractured wells in the Barnett Shale. The approach, which uses a simple physics theory called scaling, is intended to help the energy industry accurately identify low- and high-producing horizontal wells, as well as accurately predict how long it will take for gas reserves to deplete in the wells.
The first trickle of fuels made from agricultural waste is finally winding its way into the nation's energy supply. But the full benefits of this fuel source remain many years away, and ethanol, which was meant to be a stop-gap until non-food sources of fuel were found, has been far more damaging to the environment than the government predicted.
