Wind map shows untapped energy potential in cities

Putting a wind turbine on your suburban home may leave you disappointed but there is a large untapped wind energy potential in UK cities, say scientists. A new study has mapped the wind energy potential of five city regions, ...

Surface structure controls liquid spreading

Researchers at Aalto University have developed a purely geometric surface structure that is able to stop and control the spreading of liquids on different types of surfaces. The structure has an undercut edge that works for ...

How many lakes are there, and how big are they?

Because of the important role lakes play in regional and local biogeochemical cycling, including carbon storage and emissions, scientists need to know how many lakes of various sizes exist. However, determining the size distribution ...

Scientists mimic fireflies to make brighter LEDs

The nighttime twinkling of fireflies has inspired scientists to modify a light-emitting diode (LED) so it is more than one and a half times as efficient as the original. Researchers from Belgium, France, and Canada studied ...

Novel holographic antenna designs and uses

Holographic antennas first studied around 40 years ago are again a hot topic given the potential of holographic images for a variety of applications. EU researchers developed novel prototype devices based on the associated ...
