Seems you're awfully defense for doing nothing more than asking questions -- looks more like you've made up your mind and anyone who calls shenanigans is going to get blasted...
First one is obviously a sham, second one is one of those "too vague to know" situations. I don't know enough about EMF to say for sure, but it wouldn't surprise me if it's a sham. Unless someone has added a new set of rules to the existing laws of physics that I'm just not aware of, the whole notion of "overunity" is entirely impossible.
Now, if it's drawing energy from somewhere else, then it's not "overunity" is it?
