On my public non commercial website: www.kdwindturbines.nl you can find about hundred KD-reports and manuals which can be copied for free at the menu KD-reports. At the top of the list with KD-reports there is a note: "Sequence of KD-reports for self-study" which shows which reports I have written about which subjects.

At the menu "Home" there is an old video (in Dutch) in which I am interviewed near some of my VIRYA windmills. There is also a folder with a description of my former engineering office Kragten Design. I am almost 79 years old now and retired from 2018. I am no longer commercially active but my website gives a lot of free information about small electricity generating and water pumping windmills.
