Open Source Disk Generator
From Stefan Raabe
This is a forthcoming, open source electrical generator. It appears to become well-documented and analyzed, including magnetic field calculations. It appears to be an imporant contribution to humanity, as a scalable, robust, low-speed generator for many applications. We are interested in it for steam power electrical generation (both solar and fueled).
