Here's a book by edward S I haven't read it yet but its about his theory on magnetic current and magnets. Also keep in mind this man had a 4th grade education ONLY and this was in the early 1900's.

Edit - WOah woah woah, you could DEFINITLY make a perpetual battery using magnet's. I wish I had a bunch of magnets to play with

Dark Matter interests me like crazy! I hope the LHC finds some, even though they believe if they do create it, it will escape and just go wonder off wherever it wants too lol. I guess they'd be able to tell though if they had it.
