ing. Adriaan Kragten stelt al zijn rapporten gratis ter beschikking hiermee komt een grote hoeveelheid kennis voor iedereen binnen handbereik. Adriaan is iemand met vele jaren ervaring in windenergie zijn activiteiten zijn zoals hij het zelf omschrijft: "Kragten Design is a one man engineering office founded in 1989 and directed by ing. (B.Sc.) Adriaan Kragten. The main activities of this business are the development of small electricity generating windmills with PM-generators, supplying of consultancy and the writing of technical reports. Building plans of eighteen wind turbines with rotor diameters between 1 and 4.6 metre are developed."

Hieronder een overzicht van de specificaties. Er is een ruime keuze aan wiek diameter en verschillende type dynamo zoals omgebouwde a-synchroon motoren, vlakke plaat generator of een fiets naaf dynamo.
