Opening communication lines between propulsion and airflow poses new questions
11 Oct 2018 at 10:34am
On the runway to more fuel-efficient aircraft, one alternative propulsion scheme being explored is an array of electrically powered ducted fans. The fans are distributed across the wing span or integrated into the wing. Researchers have gained new understanding in how the fans and especially their precise placement on the aircraft can affect the cross-conversation between propulsion and the airflow around the wing.
Windier wind farms
4 Oct 2018 at 10:18am
Depending on how wind turbines are situated relative to each other and to the prevailing wind, those not directly in the path of the wind could be left to extract energy from significantly depleted airflow. However, according to researchers, there are ways to get around this issue of diminishing wind returns.
Large-scale US wind power would cause warming that would take roughly a centu...

Extracting energy from the wind causes climatic impacts that are small compared to current projections of 21st century warming, but large compared to the effect of reducing US electricity emissions to zero with solar. Researchers report the most accurate modelling yet of how increasing wind power would affect climate, finding that large-scale wind power generation would warm the Continental United States 0.24 degrees Celsius because wind turbines redistribute heat in the atmosphere.

The world is edging closer to a reality where smart devices are able to use their owners as an energy resource, say experts.
Physicists train robotic gliders to soar like birds
20 Sep 2018 at 7:16am
Scientists know that upward currents of warm air assist birds in flight. To understand how birds find and navigate these thermal plumes, researchers used reinforcement learning to train gliders to autonomously navigate atmospheric thermals. The research highlights the role of vertical wind accelerations and roll-wise torques as viable biological cues for soaring birds. The findings also provide a navigational strategy that directly applies to the development of UAVs.
Large wind and solar farms in the Sahara would increase heat, rain, vegetation
6 Sep 2018 at 11:16am
Wind and solar farms are known to have local effects on heat, humidity and other factors that may be beneficial -- or detrimental -- to the regions in which they are situated. A new climate-modeling study finds that a massive wind and solar installation in the Sahara Desert and neighboring Sahel would increase local temperature, precipitation and vegetation. Overall, the researchers report, the effects would likely benefit the region.
Wind turbines: How much power can they provide?
5 Sep 2018 at 9:47am
Wind turbines could cover 40 percent of the current electricity consumption in Germany.
3D printed impeller allows unmanned aircraft to operate for thousands of hours
4 Sep 2018 at 8:46am
Engineers are developing a cooled, radial gas turbine for a small generator that provides thousands of hours of electricity to an unmanned aerial vehicle (UAV), a significant improvement to current UAV turbines that only operate a few hundred hours before wearing out.
A new way to remove ice buildup without power or chemicals
31 Aug 2018 at 12:01pm
Researchers have found a way to prevent icing of powerlines, airplanes, wind turbines, and other surfaces with a special coating and the power of sunlight -- no heating or harsh chemicals needed.
The science behind blowing bubbles
28 Aug 2018 at 5:59am
What exactly happens when you blow on a soap film to make a bubble? Behind this simple question about a favorite childhood activity is some real science, researchers have found.
Europe may thrive on renewable energy despite unpredictable weather
26 Jul 2018 at 1:12pm
Researchers have shown how long-term weather patterns affect wind and solar renewable energy technologies across Europe. The work suggests that despite the unpredictable nature of wind and solar energy, the European power system can comfortably generate at least 35 percent of its electricity using these renewables alone without major impacts on prices or system stability.
Different strategy of cycling teams in escape attempts
11 Jul 2018 at 7:55am
A new study based on wind tunnel research on a peloton of 121 cyclists may explain why so few 'breakaways' in professional cycling races, like this year's Tour de France, are successful.
Oil rigs may end their days as valuable artificial reefs
9 Jul 2018 at 7:46am
A large group of international researchers have just published a scientific article in which they encourage environmental authorities across the globe to rethink the idea of removing oil rigs, wind turbines and other installations in the sea when they are worn out.
Evaluation method for the impact of wind power fluctuation on power system qu...
20 Jun 2018 at 6:47am
Abrupt changes of wind power generation output are a source of severe damage to power systems. Researchers have developed a stochastic modeling method that enables to evaluate the impact of such phenomena.
Does living near wind turbines negatively impact human health?
5 Jun 2018 at 8:21am
Wind turbines are a source of clean renewable energy, but some people who live nearby describe the shadow flicker, the audible sounds and the subaudible sound pressure levels as 'annoying.' They claim this nuisance negatively impacts their quality of life.
