Winnowave is developing wind concentrators - a vertical wall of shipping containers - to install in front of wind turbines to increase the wind speed experienced by the wind turbine and thereby inproving the energy production from the wind turbine. Our first minimum viable product is built from used or scrapped shipping containers installed just in front of a wind turbine on an uni-wind-directional site. Many wind turbines are currently installed on uni-wind-directional sites in for example Spain, Brazil, France or Mexico. CFD calculations and wind measurements have shown an increase in power production from the wind turbine at 30% on a flat site and significantly more when the wind turbine is situated on the top of a hill. When using scrapped containers, the businesscase is extremely good. It is a totally new technology and we have filed 8 patent applications. For a Vestas V-90 wind turbine we designed a container wall from 50 HQ containers with wire supports and earth anchors. It is designed according to the Euro code. Our customers are wind turbine operators and our first customer will most likely be Iberdrola, Enel, Actiona or EDF. They all showed much interest in our product. One founder, Peter Grabau, has optimized wind turbine blades for 30 years and looked for new ways to improve energy production. The other founder, Manuel Alcocer, has sold Vestas wind turbines in Brazil for 4 years and he found all sites to be uni-wind-directional why got the idea.
