Kragten Design no longer a commercial company
« on: December 01, 2017, 11:08:51 AM »
I am 70 years old now and I am almost five years retired and so I decided to no longer perform commercial activities. This means that I will no longer accept paid design work and that the licenses for my bigger VIRYA wind turbines, for which a licence fee was required, are no longer available. So everything what you can find on my website www.kdwindturbines.nl is available for free. You find more than 60 public KD-reports about different technical aspects of small windmills and seven VIRYA designs including drawings of small battery charging windmills. A guide through most of my reports is given in the note: "Sequence of KD-reports for self-study" which you find at the top of the menu "KD-reports". More information about the change is given in the folder of Kragten Design at the menu "Home". This new policy is in better accordance with the policy of Otherpower.

Hi,

I took the time to check out the KD Reports http://kdwindturbines.nl/kd-reports/

I found one report I really liked but could not find it again.

The list does not give a description with the links(just numbers) so its hard to browse the list.

The first note at the menu "KD-reports" is the list with all the public KD-reports. Every report has a rather long title so reading the titles gives you a good impression of the content of each report. First I thought that this list is enough to find the subject in which you might be interested. But I still got questions which indicated that people don't read the list or that they don't understand the title. So I wrote the second note "Sequence of KD-reports for self-study". This is a story of two pages which tells you which report you can study if you want information about a certain aspect of the design of a wind turbine, like the rotor, the generator, the safety system, the tower and the electronics. This second note was derived from the program of a wind energy course which I gave in Tanzania. Reading this second note doesn't take more than five minutes, so I really don't know how I can give a more efficient method to find your way on my website.

Thank you for sharing your years of experience with us.  I plan on building some of the designs soon

Thank you Adriaan.  Your work has been interesting reading ever since you joined 5 years ago.  Looking forward to many more!

The link which JW placed to the list with KD-reports is no longer working because I have changed the list. The new list is on top of the menu KD-reports on my website www.kdwindturbines.nl. The second file, which is the folder "Sequence of KD-reports for self-study", has been changed too.
