In an attempt to prevent vast quantities of oil from fouling beaches and marshes after the 2010 Deepwater Horizon spill in the Gulf of Mexico, BP applied 1.84 million gallons of chemical dispersant. The dispersant was thought to rapidly degrade in the environment, but a new study has found that the DOSS dispersant compound remains associated with oil and can persist in the environment for up to four years.

The University of Notre Dame, along with GE and four other public entities, are collaborating on a $36 million project to create a research and testing center to advance the technology of gas turbine engines used for jet aircraft, power generation plants and the oil and gas industry. GE has committed $13.5 million over the next five years to fund research at the Notre Dame Turbomachinery Facility, which was unveiled this week in Indiana.
By fusing together the concepts of active fiber sensors and high-temperature fiber sensors, a team of researchers at the Univ. of Pittsburgh has created an all-optical high-temperature sensor for gas flow measurements that operates at record-setting temperatures above 800 C. The new technology should be ideal for use in deep drilling operations, nuclear reactor cores and outer space.
Concentrating solar power (CSP) could supply a large fraction of the power supply in a decarbonized energy system, according to a new study of the technology and its potential practical application. For this research, scientists simulated the construction and operation of CSP systems in four regions around the world, taking into account weather variations, plant locations, electricity demand, and costs.
Researchers in Europe have designed a new type of fuel cell that is much simpler and can be mounted on a wall and used in a home. Designed with heater manufacturer Vaillant, the compact and safe system is based on solid fuel cell technology and generates electricity and heat from natural gas. With an output of 1 kW, it provides the average current consumption for a four-person household.
A Swiss-made solar-powered aircraft has made a successful inaugural flight as its makers prepare for what they hope will be the first round-the-world solar flight. The aircraft spent 2 hours and 17 minutes in the air above western Switzerland early Monday. The Solar Impulse 2 is a bigger and better version of a single-seat prototype that first took flight five years ago and can theoretically stay airborne indefinitely.
In a typical wind farm, the wind turbine located in the wakes of upstream turbines would experience a much different surface wind compared to the ones located upwind due to wake interferences. Scientists at Iowa State Univ. have completed a study on the effects of these relative rotation directions, using two tandem wind turbines as a model. They found a big difference in performance between co-rotating and counter-rotating turbines.
In an effort to better understand what persuades people to buy photovoltaic systems for their homes, researchers at Sandia National Laboratories are gathering data on consumer motivations that can feed computer models and thus lead to greater use of solar energy. A primary goal of the project is to help increase the nation’s share of solar energy in the electricity market from its current share of less than .05% to at least 14% by 2030.
There is an optimum size for electrical networks if what is being considered is the risk of a blackout. This is the conclusion reached by a scientific study by researchers in Spain and the U.S. The study, which analyzed the dynamics of these complex infrastructures, found that an optimum adequate size exists that helps guarantee correct functioning of an electrical network.
Solar Frontier and the State Univ. of New York College of Nanoscale Science and Engineering have signed a memorandum of understanding to conduct a technical and economic feasibility study for potential joint R&D and manufacturing of CIS thin-film modules in Buffalo, New York. This move is part of Solar Frontier’s plans to establish production bases for its proprietary technology outside of Japan, the company’s home market.
Navy researchers have recently demonstrated sustained flight of a radio-controlled P-51 fighter replica fueled by a new gas-to-liquid process that uses seawater as carbon feedstock. The fuel is made using an innovative and proprietary electrolytic cation exchange module that separates gases from water at 92% efficiency. Catalysis converts the gases to liquid hydrocarbons.
In a recent advance in solar energy, researchers have discovered a way to tap the sun not only as a source of power, but also to directly produce the solar energy materials that make this possible.
New research is focusing on enhancing poplar trees so they can break down easier and thus improving their viability as a biofuel. The long-term efforts and teamwork involved to find this solution can be described as a rare, top-down approach to engineering plants for digestibility.
Chemists have settled the debate about a fundamental question that is relevant to the conversion of one color into another and demonstrated how to influence the efficiency of this process by changing the refractive index around the material.
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.
