So, as I am a ´physical layman´, this website is written by popular language, using casual terms. As quite new theories are developed and new designs are created, some new terms had to be defined too. As I am German and did translate these pages into English by myself, even more common these texts will be, using but simplest words. However, all conciderations and designs are related to lots of figures, so everyone may well understand, what´s talked about.

Chapters and sections
This website is structured by chapters and sections, each marked by date written resp. first published at the web. Chapters are small pages with guid-line texts, embedded links will show related sections. Also there, links will show more details. Main chapters here are (ordered by date written):

- Crop Circles - first analyses and concepts of technical solutions,
- Sling and Swing - second attempt to create theories and designs,
- Physics of Sling - comprehensive workout of essential facts, effects and solutions,
- Summary - one page with brief informations about problems, basic principles and solutions,
- Appendix - will show additional developments.

Reading sequence
Thus for brief information about subjects here, you may first study page of Summary. Best structured description of theory and engines you will find at Physics of Sling. From there by links you may find earlier documented details of chapters Crop Circle and Sling and Swing, both showing development of ideas in chonological order. These chapters and sections were finished April 2000. Later developments are summericed at Appendix, for example this Centrifugal-power-spider.

You also could use the Sitemap to open chapters and section (and use back-key). Printout of all these website-pages would take some 150 pages. If you seriously are interested, you better would study offline by using prepared download-files.

Hope you enjoy reading this website - above this, you may contribute to develope usage of Free energy, any kind.
