As Juan Luis Larrabe explained, the idea is for such vessels to take advantage of the energy from the wind movement in order to generate electricity: “The wind energy is gathered in the sails and the propeller operates as a turbine. This turbine is connected to an electric generator which charges up electric batteries in such a way that, when you want to propel the vessel and there is no wind, you can use this stored energy while avoiding using the internal combustion engine”.
It is a hybrid model and not exclusively electrical (the latter would mean reduced operational range, apart from the fact that the great volume of batteries required today would make it unviable). “You still have to have the traditional engines on board, but the idea is to use them as little as possible”, explained Mr Larrabe.
In this first phase, most of the theoretical work required by the project was undertaken. As Mr Larrabe stated, “in order to characterise the vessel from a mathematical perspective and draw up a preliminary design”. That is to say, they calculated what the various elements taking part in the hybridisation of the boat should be – the hull, the propeller, the hull-propeller interaction, the electrical/electronic machinery and the internal combustion engine. Then they put all this data together to “carry out simulations with different strategies of hybridisation to find out which of these might be the most efficient, from a theoretical perspective, for this vessel”. They have also designed a navigation course from the port and which will be used in upcoming and more practical stages of the project.Seeking funding
For this second simulation stage, the team will need the help of students from the school. Moreover, both for this phase as for the third - in which the prototype will be finalised -, it is essential to have funding. To this end, they are looking to collaboration with ancillary enterprises in the Basque naval engineering sector, a sector for which the project is a highly interesting one given that, as Mr Larrabe reminds us, “it could well be a new business model for a sector that is none too healthy”.Safer

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
