Being able to charge up to 30 electric cars at once requires some ingenious energy management. Researchers are incorporating a mix of renewables into the design of a smart grid for Germany’s largest charging station.
They slither, they hiss, they… fly? Don’t let their wingless bodies fool you —- some snakes can glide as far as 100 feet through the air, jumping off tree branches and rotating their ribs to flatten their bodies and move from side to side. New research investigates the workings behind the flight and whether they can be applied to mechanical issues.
Computer simulations have shown that offshore wind farms with thousands of wind turbines could have sapped the power of three real-life hurricanes, significantly decreasing their winds and accompanying storm surge, and possibly preventing billions of dollars in damages. In the case of Hurricane Katrina, the computer model revealed that an array of 78,000 wind turbines off the coast of New Orleans would have significantly weakened the hurricane well before it made landfall.
There has been some debate about whether wind turbines have a more limited shelf-life than other energy technologies. A previous study used a statistical model to estimate that electricity output from wind turbines declines by a third after only ten years of operation. Some opponents of wind power have argued that aging turbine technology could need replacing en masse after as little as ten years, which would make it an unattractive option in economic terms. In a new study, researchers carried out an analysis using local wind speed data from NASA, and showed that the turbines will last their full life of about 25 years before they need to be upgraded.
Engineers have refurbished an icing wind tunnel and are using it to study ice buildup on aircraft wings and wind turbine blades. A better understanding of the icing problems could lead to better solutions.
The development of wind farms in Europe only has an extremely limited impact on the climate at the continental scale, and this will remain true until at least 2020. These are the main conclusions of a new study.
The rotor and mast of a wind turbine can oscillate even in normal operation. The analysis of these oscillations plays an important role when the equipment is being developed and maintained. Up to now, this analysis has only been possible at discrete points located directly on equipment. Researchers have now demonstrated that using modern information technology to remotely measure the oscillatory pattern over the entire structure of the facility is possible from several hundred meters away.
They can be seen from afar -- the blinking beacons on wind turbines -- intended to warn approaching aircraft at night. However, the continual blinking disturbs many people. Beacons that only switch on when necessary find more acceptance.
Scientists 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. The rest of the power system's resources have traditionally been adjusted around wind to support a reliable and efficient system. The research that led to this report challenges that concept.
Electrical engineers have designed a micro-windmill that generates wind energy and may become an innovative solution to cell phone batteries constantly in need of recharging and home energy generation where large windmills are not preferred.
Researchers have found that an increase in the use of wind power generation can make the power grid more fragile and susceptible to disruptions. But the researchers didn't just identify the problem -- they have also devised a technique for coordinating wind power generation and energy storage in order to minimize the potential for such power disruptions.
A new study finds that in Texas, the US state that annually generates the most electricity, the transition from coal to natural gas for electricity generation is saving water and making the state less vulnerable to drought.
While Europe invests in wind energy, Norwegian hydropower offers the key to stable electricity supplies. The key driver of the development of a northern European offshore power grid is the massive investment being made in wind power in the Baltic and in and around the North Sea. The aim here is to reduce CO2 emissions by as much as between 80 and 95 per cent by 2050.
Renewable energy sources such as wind-powered generators can be more reliable and efficient by better controlling the process of getting electricity onto the power grid, according to new research.
Many owl species have developed specialized plumage to effectively eliminate the aerodynamic noise from their wings -- allowing them to hunt and capture their prey in silence. A research group is working to solve the mystery of exactly how owls achieve this acoustic stealth -- work that may one day help bring “silent owl technology” to the design of aircraft, wind turbines, and submarines.
