For anyone who hasn’t seen this guide by Patrick Kelly, and particularly if you’re new to this field, then it’s certainly worth a read. It does not have all the answers and indeed Kelly never claims this to be the case, he has simply done a lot of work compiling all the information into one place. There are hundreds of pages, and all sorts of useful and relevant information. There are things that strike chords and get you thinking... and for some people there may just be the thing that fires the spark and triggers a brainwave.
It is by all account an ongoing work, updated and revised as new things develop or new information is acquired. Personally I think the guy deserves a medal.
This is a link to the version 13.6 released 5th Jan 2010.http://www.free-energy-info.co.uk/index2.html
There are some 13 chapters, providing information about most of the OU devices we will inevitably be dealing with here.
It's free and can be copied. Take a look, you might want to put it under it's own heading.
