In a post dated April 09, 2008, I reported the first production in Belgium of an aerogenerator using prefabricated panels allowing economical mass production. The model installed on a guyed mast using a hydraulic cylinder allows easy maintenance. Luc Haegeman's very beautiful creation fits perfectly into a landscaped setting, and the criticism that can be made of spinning propellers is erased by a rotation with a vertical axis. It probably remains to test the reliability of the machine under various wind conditions and to study production costs and profitability before proposing on the market the most efficient way to switch from fossil fuels to renewable energies, and to supply the energy necessary for the operation of the twin-tube cross-border monorail.
