Bayer PU system used for wind blades in Spain
Leverkusen, Germany -- Spanish company Kliux Energies - Geólica Innovations SL has developed a technology for harnessing wind energy, using integral skin foam based on a Bayer's Baydur polyurethane system.
The technology is based on special rotors positioned vertically so that they are always facing the wind. Integral skin foam developed from the Baydur PU system was selected as the material for the rotor blades, as it meets the demands on strength and lightweight design, BMS said in a 28 June statement.
BMS claimed the new wind turbines generate electricity from wind speeds of just four metres per second, making them very efficient. Including the mast, the turbines are nine metres high.
"The rotor's unique aerodynamic shape ensures smooth rotation and continuous energy generation, even with varying or strong winds," said Inaki Eguizábal, ceo of Kliux Energies - Geólica Innovations.
The first pilot system was installed in the Rioja region around Logrono, home to the Kliux Energies' head office, where it has been running successfully since its installation in summer 2010, BMS said. Another pilot system is up and running at Bayer MaterialScience's Tarragona site in Spain, where it is used for test and presentation purposes.
At present, Kliux Energies is working on a mini version of the wind turbine that is just 50 cm high. It is intended as a mobile solution for boats, trailers and camping sites and for sustainable lighting in public spaces.
