free KD-reports

As I am retired for some years now, I no longer need income from selling my KD-reports about small wind turbines. So I have decided that from now on all my public KD-reports can be copied for free by anybody. This concerns ten more reports with former prices in between € 20 and € 40. My most important report is certainly KD 35: Rotor design and matching for horizontal axis wind turbines. Report KD 196 gives questions and answers about each chapter of KD 35 in English and in Dutch. A list of all 46 free public KD-reports is given as the first item of the menu KD-reports on my website: www.kdwindturbines.nl. All reports have a rather long title which gives a good impression of the content.

The most recent report is KD 598: Ideas about the 3-bladed VIRYA-0.65 water turbine with 20° inclined shaft coupled to the generator of the VIRYA-2.68 windmill for 12 V battery charging.
