Computer models show clear advantages in new types of wind turbines

Researchers have modeled the fluid dynamics of multi-rotor wind turbines via high-resolution numerical simulations. The simulations demonstrate a clear advantage for a turbine model with four rotors. The researchers found, that the wind turbine wake recovers much faster with multi-rotor turbines, that multi-rotor turbines produce slightly more energy than single-rotor turbines, and that a turbine…

Volleyball: The secret to sneaky float serves

A team of researchers performed wind tunnel experiments to determine the role of asymmetry caused by the orientation of a volleyball on its aerodynamic characteristics. They found that switching from the standard panel arrangement to a hexagonal or dimpled pattern may improve the consistency of flight, with many potential applications in aviation.

Model helps choose wind farm locations, predicts output

The wind is always blowing somewhere, but deciding where to locate a wind farm is a bit more complicated than holding up a wet finger. Now a team of researchers has a model that can locate the best place for the wind farm and even help with 24-hour predictions of energy output. Read Full Article…

New report deepens understanding of wind-wildlife interactions

An increase in the generation of wind energy is a key component of the U.S. strategy to reduce carbon emissions from the power sector. Approximately 97 gigawatts of wind energy production capacity are currently installed in the U.S., and in 2018, wind energy supplied about 6.5% of the nation’s electricity. Scenarios developed by various groups,…

Growth of wind energy points to future challenges, promise

Advances in adapting the technology and better methods for predicting wind conditions have fanned significant growth of the use of wind turbines for electricity in the last 40 years. A new report takes stock of where the field is now and what lies ahead. Researchers surveyed the growth of wind technology as a source of…

A new material for the battery of the future

Researchers have discovered a new high performance and safe battery material (LTPS) capable of speeding up charge and discharge to a level never observed so far. Practically, if the first tests are confirmed, this new material could be used in the batteries of the future with better energy storage, faster charge and discharge and higher…

Engineered bacteria could be missing link in energy storage

One of the big issues with sustainable energy systems is how to store electricity that’s generated from wind, solar and waves. At present, no existing technology provides large-scale storage and energy retrieval for sustainable energy at a low financial and environmental cost. Engineered electroactive microbes could be part of the solution. Read Full Article Here…

Offshore wind farm increased tourism on Block Island

Researchers who analyzed AirBnB rental data before and after construction of the Block Island Wind Farm have found that, contrary to some concerns, the turbines have been linked with increased tourism on the island. Read Full Article Here For more great articles: Wind Energy News

The complicated future of offshore wind power in the US

In recent years the US Department of Energy laid out an ambitious plan to grow the US offshore wind sector. Researchers make the case that it might not be as easy as it seems, citing specifically the challenge of supplying rare-earth metals needed to build these offshore wind turbines.

How to ice-proof the next generation of aircraft

To prevent ice formation on aircraft during flight, current systems utilize the heat generated by burning fuel, but these high-temperature, fuel-dependent systems cannot be used on the proposed all-electric, temperature-sensitive materials of next-generation aircraft. As some scientists search for new anti-icing methods, some have taken a different approach. They’ve published evidence showing that equipment important…

How power-to-gas technology can be green and profitable

Hydrogen production based on wind power can already be commercially viable today. Until now, it was generally assumed that this environmentally friendly power-to-gas technology could not be implemented profitably. Economists have now described, based on the market situations in Germany and Texas, how flexible production facilities could make this technology a key component in the…
