Well my first real recommendation is books about Victor Schauberger. I cant speak for them all but expect they will be good. I am currently reading "Living Energies" by Callcum Coats which is excellent, although is has some real oddball stuff there if you can cope with that the ideas behind it are well worth it! Although Coats' other book "The Energy Evolution" is a translation of difficult to understand German, but since its from Scaubergers original articles it might be more to his original point, dont know haven't read it yet :)
- if you have a firm grounding in physics you might want to try "Collective Electrodynamics" by Carver A Mead because IMO its a very important book! But like the name implies, its not light reading... :lol:
- For an engineering perspective on the zero-point field read "Quest for Zero-Point Energy" by Moray B King - what can I say?!? Free energy stuff well explained
have fun
