Finnish high-tech company PEM-Energy has chosen Telene for its new, small-scale MyPower wind turbine.
Founded in 1988, PEM-Energy manufactures MyPower wind turbines and components for household and business use. “Generating your household energy by wind power can be a private response to climate change,” says Mikael Seppälä, Managing Director of PEM-Energy Oy. “A wind turbine can generate energy for a house or summer cottage, even for a business, by arranging several turbines in a system. Our aim is to enable self-sufficient energy production without putting a load on the environment.”
The turbine pays for itself in a relatively short time: three to seven years, depending on local wind conditions and the price of electricity. Wind power is also environmentally friendly. The turbine has a nominal output of 2 kW, a mast height of five meters and a turbine diameter of four meters. It generates about 5,000-12,000 kWh of energy a year and up to 15,000 kWh a year on windy shores.
“Telene is our material of choice due to its excellent strength, resilience and durability” says Juhani Pylkkänen, Professor of Production Technology at the University of Oulu (north Finland), who participated in research and development for the windmill.
“Compared with alternative materials, Telene has a better quality surface. It retains its shape well, lends itself to moulding into integrated structural parts and withstands the test of time and difficult weather conditions better than other plastic materials. The difficult manufacturing process and high price of carbon fibre and similar materials restrict their usability, while aluminium and composite structures did not have the required tenacity in our tests,” Pylkkänen concludes. Juhani Pylkkänen is delighted with the service orientation of the parts supplier: “Junkkari Muovi, who moulds the windmill parts in Telene readily offered help in strength calculations and moulding design. Their support also played a crucial role in the choice of material.”
”Besides the specific advantage of Telene’s closed mould process which allows reduction of COVs traditionally associated with GRP Hand-Lay-Up or Spray-Up processes, all Telene grades offer a favourable energy balance* when compared to several other materials: four times lower than for Polypropylene and ten times lower than for Polycarbonate,” said Alexander Daemen, President of Telene SAS.
Composite products, based on polyurethane technologies from global chemical company Huntsman, are taking centre stage at a design exhibition at the Design Museum Gent, Belgium.
In late November, the 14 project partners in the MoPaHyb consortium developing a modular production plant for hybrid high-performance components wrapped up their successful efforts with a two-day symposium in Pfinztal, Germany.
Alvant says its aluminium matrix composite is proven to offer significant weight and performance benefits for rotor applications found in electric motors, flywheels, fans and turbines.
