Obtaining energy from marine currents
20 Mar 2018 at 7:24am
Researchers have developed procedures and designs to obtain energy from marine currents in areas of great depths optimizing the costs.
Chirping is welcome in birds but not in fusion devices
16 Mar 2018 at 12:39pm
Birds do it and so do doughnut-shaped fusion facilities called 'tokamaks.' But tokamak chirping -- a rapidly changing frequency wave that can be far above what the human ear can detect -- is hardly welcome to researchers who seek to bring the fusion that powers the sun and stars to Earth.
Research gets closer to producing revolutionary battery to power renewable en...

New research verges on development of a commercial hydrogen-bromine flow battery, an advanced industrial-scale battery design engineers have strived to develop since the 1960s.
The principle of electric wind in plasma
2 Mar 2018 at 7:45am
Scientists have identified the basic principle of electric wind in plasma. This finding will contribute to developing technology in various applications of plasma, including fluid control technology.
Wind and solar power could meet four-fifths of US electricity demand, study f...
27 Feb 2018 at 8:16am
The United States could reliably meet about 80 percent of its electricity demand with solar and wind power generation, according to scientists.
Chemical cluster could transform energy storage for large electrical grids
13 Feb 2018 at 11:58am
Researchers believe they have found a promising compound that could transform the energy storage landscape. The compound has properties that make it an ideal candidate material for redox flow batteries.
Improving drone performance in headwinds
9 Feb 2018 at 7:07am
Stability of unmanned aerial vehicles in heavy winds can be improved through rotor placement and angle.
Avoiding blackouts with 100% renewable energy
8 Feb 2018 at 11:12am
Researchers propose three separate ways to avoid blackouts if the world transitions all its energy to electricity or direct heat and provides the energy with 100 percent wind, water and sunlight. The solutions reduce energy requirements, health damage and climate damage.
Using shark scales to design better drones, planes, and wind turbines
7 Feb 2018 at 6:01am
A team of evolutionary biologists and engineers have demonstrated a new structure inspired by shark skin that could improve the aerodynamic performance of planes, wind turbines, drones, and cars. The research sheds light on a decades-old mystery about sharkskin.
How wind turbines annoy residents and how to reduce it
24 Jan 2018 at 8:11am
When falling asleep, relaxing or undertaking recreational activities, nearly a third of residents living near a wind farm are not at all annoyed or only slightly annoyed by the noise of wind turbines. One in ten people experience symptoms of stress. However, noise is not the only problem. In particular, a critical attitude towards a wind farm stimulates the experience of stress. A better information policy during the planning phase could help alleviate problems for residents.
New materials being developed to prevent wind turbine damage
9 Jan 2018 at 3:48pm
Researchers in Spain are developing new materials that will make wind turbines more resistant to the extreme climate conditions they have to withstand.
Sun, wind, and power trading
9 Jan 2018 at 7:28am
The use of renewables like the sun and wind can cause fluctuations in power grids. But what impact do these fluctuations have on security of supply? To answer this question, scientists analyzed different types of fluctuations in several power grids in Europe, Japan, and the USA -- and came to surprising conclusions.
A global north-to-south shift in wind power by end of century
11 Dec 2017 at 9:04am
Wind resources in the next century may decrease in many regions in the Northern Hemisphere -- and could sharply increase in several hotspot regions down south.
Transformation to wind and solar achievable with low indirect GHG emissions
8 Dec 2017 at 8:35am
Different low carbon technologies from wind or solar energy to fossil carbon capture and sequestration (CCS) differ greatly when it comes to indirect GHG emissions in their life cycle. The new study finds that wind and solar energy belong to the more favorable when it comes to life-cycle emissions and scaling up these technologies would induce only modest indirect GHG emissions -- and hence not impede the transformation towards a climate-friendly power system.
Inspecting rotor blades with thermography and acoustic monitoring
1 Dec 2017 at 7:47am
Wind turbines have a design life of 20 years. The rotor blades must be regularly inspected at least once every four years to verify their structural integrity. This type of work is performed by industrial climbers. But the problem with inspecting offshore installations is that access is only possible when wind and weather conditions permit. This makes it very difficult to plan inspection visits. In the Thermoflight research project, scientists are working together with industrial and research partners to investigate alternative inspection methods. The use of offshore drones equipped with thermal imaging cameras in combination with acoustic monitoring systems could potentially improve maintenance efficiency and help reduce downtime.
