99% Natural Timber Tower for Wind Turbines
Timber Tower makes wooden wind power towers up to 200 meters tall for wind turbines. Their test tower at Hannover employs a 1.5 MW Vensys wind turbine, which has been estimated to generate electricity for about 1,000 homes. The turbine weighs one hundred tons.
The timber tower support structure is a wooden hollow column with a multi-sided cross-section. Hexagonal, octagonal, or dodecagonal cross-sections are used. The timber used to make the wooden pieces are sourced from ecologically and economically responsible forestry practices. The wood has a PEFC certificate, which is a standard in Europe for socially responsible business.
One of the main advantages of using wood for wind power towers is cost. Steel can by very expensive, but locally sourced timber typically is much cheaper. Another advantage is transportation of the tower materials and pieces to challenging locations. Wood materials are easier to carry via large trucks than tubular steel sections.
Timber Towers are guaranteed to have a minimum life cycle of twenty years. Once a tower has exhausted its usefulness, the materials can be recycled.
