Up to 20 million homes in Europe could be powered by clean renewable energy from the sea, according to ocean energy expert Teresa Pontes of Portugal, who was speaking at the EurOCEAN marine science and policy event in Galway today (12th May). She estimated that, by harnessing energy from waves and marine currents, Europe would produce around 200 TerraWatt (200 million megawatt) hours per year of electrical power.
“The oceans contain a huge energy resource with different origins,” said Ms. Teresa Pontes. “The most developed conversion technologies are for tidal energy, thermal energy, marine currents and ocean waves. The last two technologies are those which have received most attention in that last fifteen years, as they show the best prospects of becoming competitive in the short to medium term.”
Wave and marine current energy generation are generally considered to be environmentally benign, with the only impacts being visual intrusion and possibly noise from air turbines on shoreline wave power plants. For offshore ocean energy plants the only conflicts could come from shipping, navigation and fishing and most of these conflicts could be minimised and, in some cases, eliminated at the planning stage.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
