Dispersant from Deepwater Horizon spill found to persist in the environment

July 16, 2014 12:51 pm | News | Comments

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.

Solar Impulse 2 makes maiden flight

June 2, 2014 9:20 am | Videos | Comments

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.

New concept to improve power production of wind turbines

May 23, 2014 12:46 pm | News | Comments

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.

Planting the “SEEDS” of solar technology in the home

May 20, 2014 2:35 pm | News | Comments

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.

The largest electrical networks are not the best

May 12, 2014 2:55 pm | News | Comments

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.

SUNY college may partner with Solar Frontier on thin-film R&D, production

April 23, 2014 9:33 am | News | Comments

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.

Scale model World War II craft takes flight with fuel from the sea

April 7, 2014 6:06 pm | News | Comments

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.

Energy breakthrough uses sun to create solar energy materials

April 4, 2014 3:32 pm | News | Comments

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.

Algae may be a potential source of biofuels, biochemicals even in cool climate

March 20, 2014 12:22 pm | News | Comments

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.

New algorithm improves the efficiency of small wind turbines

March 18, 2014 9:47 am | News | Comments

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.

GE introduces a new technology for home refrigeration

March 14, 2014 9:45 am | News | Comments

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.

Measuring wind turbines remotely

March 5, 2014 2:57 pm | News | Comments

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.

Nuclear dump leak raises questions about cleanup

February 28, 2014 2:56 pm | by Jeri Clausing, Associated Press | News | Comments

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.
