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

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
