Below are two movies of the group who are busy making turbines. Metal tubes of 90 mm outer diameter can be used for monopile towers but are very scarce and expensive in Mali.
Therefore Gael Oliveira – who is currently in Mali – has been looking onto an alternative design where we use abundant available materials such as water tubes and construction steel bars (used for strengthening concrete walls). Having such cost-out projects are important in order to make these wind turbines more attractive compared with its competitors (gasoline generators).
