Solar-Active-Houses heat themselves using heat collectors and water tanks. However, no one had conducted an objective assessment of how efficiently they do so. Researchers put some of these solar houses to the test, identified where there was room for improvement and laid the scientific groundwork for this housing concept.
EU's grid connected cumulative capacity in 2014 reached 129 GW, meeting 8% of European electricity demand, equivalent to the combined annual consumption of Belgium, the Netherlands, Greece and Ireland.
Transferring power from Africa to Europe via a high voltage direct current (HVDC) transmission line could be a sustainable business model with added value for both regions. This is the conclusion reached by researchers in the EU-sponsored BETTER project.
A metal-free alternative catalyst for fuel cells may be at hand. A team of chemists introduces a new approach that uses a molecular catalyst system instead of solid catalysts. Although molecular catalysts have been explored before, earlier examples were much less efficient than the traditional platinum catalyst.
The quality of waters can be assessed using of the organisms occurring therein. This approach often results in errors, because many species look alike. Therefore, new methods focus on DNA analyses instead.
