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uses a multipolar technology and distinguishes itself from conventional machines in that mechanical elements have been replaced by electronic ones, i.e. the "multiplier" which reproduced wind power as electricity has been replaced and 60 magnets have been installed in the "rotors" (the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: Making Waves

Computer scientists use wave packet theory to develop realistic, detailed water wave simulations in real time. Their results will be presented at this year’s SIGGRAPH conference.

Think about the last time you were at a lake, river, or the ocean. Remember the ripples of the water, the waves crashing against the rocks, the wake following...

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
