Still doing some basic research - not on the concepts "Larry Spring" reports, but on the nature of the beast itself.
I have thus far found absolutely no reputable groups or organizations that discuss Larry Spring.
I did, however, find his name mentioned in various Tesla discussion groups, and it seems to be slipped in there particularly to link back to his site, or to articles that all start off with: "I, Larry Spring, discovered..." with similar but varied words following the declarative. Sounds like the language in spam, mass advertising, and infomercials. His school association seems dubious, but I still have to look that up.
Interestingly enough, "magnesphere" does get some hits:

meaningI've only looked through one of Spring's experiments so far, and I'm not impressed. I see how it demonstrates what he is showing *because the explanation says it does*, just as it demonstrates what acknowledged science shows. I don't see how it proves what he believes to the exclusion of what everyone else sees.
Edit: The International Tesla Society - since broken up, with one of its alleged founding members linking to a porn site in a letter to allow those former members who wish to continue on in the spirit of Tesla and help him with his research - is discussed in Wired, back in 1998,
here. Keep in mind, this society is held in a position of high esteem on Spring's biography.
I'll still be collecting information on this, but I'm now more sure than ever that there's something fishy behind all this.
