A giant wind-powered generator

14.10.2003


The new TWT-1650 wind-powered generator presented in Pamplona has 36-metre vanes which, in a circular movement, sweep an area greater than that of a football pitch and which can withstand extremes of weather, including winds of up to 110 kilometres an hour.



This device, made by Grupo Mtorres in collaboration with the Institute for the Diversification and Saving of Energy (IDAE), is beginning its commercial life, after three years of tests.

The new model, with a power of 1,650 kilowatts, uses a multipolar technology and distinguishes itself from conventional machines in that mechanical elements have been replaced by electronic ones, i.e. the "multiplier" which reproduced wind power as electricity has been replaced and 60 magnets have been installed in the "rotors" (the part that gyrates).


The system has environmental advantages, as well as ones of costs and energy yield, given that the mechanical part of wind-powered generators are the cause of 30% of the failures and errors in these machines. In other words, an important percentage of maintenance costs will disappear.

This is why a new wind park concept is considered: distributed energy generation, i.e. small installations with three to six machines and near the consumer and connected directly to the distribution grid.

This means less noise and less visual impact on mountain ridges and by the migratory routes for birds, as well as eliminating the use of lubricant oils which the machinery mechanics needed (300 litres per year).

The disadvantages of this technological development is that the wind-powered generator has more weight and volume (this Group is even considering achieving 50-metre long vanes made up of carbon-fibre modules) and the initial investment and costs is greater than the conventional models.

Energetically the machine – which has a computer which controls what is done at any moment depending on wind direction – better withstands troughs in the grid and is therefore more reliable in power cut situations.

The Mtorres Group and the German company, Enercom are the only enterprises developing this technology.

Im Focus: First evidence on the source of extragalactic particles

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...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

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...

Im Focus: Breaking the bond: To take part or not?

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...

Im Focus: New 2D Spectroscopy Methods

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....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
