Don't be too frightened. Here's a little extra info on Tom Bearden (who was mentioned on the links you gave) from another website:
Tom Bearden is today known as the self styled expert on over-unity physics. That is to say, electrical systems that put more energy out than goes in. However, this position of pre-eminence, has been achieved not by the conventional means of publishing papers in peer reviewed journals, attending mainstream scientific conferences, or even providing working demonstrations, but rather by playing to the crank fringe audience on the internet, with a sustained and substantial publicity effort that now exceeds 10 years in duration.
What has made the rise of Mr Bearden possible, has been the general absence of critical discussion of his methods and concepts. This is not surprising, since Mr Bearden has consistently kept away from those who are qualified to evaluate his claims, and prefers instead to keep company only with those who are uncritical in accepting his statements of knowledge.
Hence, the purpose of this document, is for the first time, to undertake a critical evaluation of the claims made by T.E. Bearden, to place them in a context, and evaluate whether there is any intrinsic value in any of the work undertaken by Mr Bearden.
I want to state the amount of nonsensical material Mr Bearden has produced over the years is simply too enormous to possibly be covered, and I have had to leave out gems such as claims Tom Bearden has provided a physical mechanism for re-incarnation, among numerous other absurdities.
