@Chef,
Well what else could there be that anybody for the last 120 years couldn't see in Tesla's work. As far as I am concerned the disbelief has presided over the group mindset propogated by the disbelievers or some overarching controlling group that has purposefully kept the process under wraps.
The different levels of the involved from the bottom up:
MIB, TROLLs, Trollers, Nay sayers, Disbelievers, Noobs, amazed, astonished, curious, questioners, posters, experimenters, librarians,extolers, pontificators, pontifs, minor popes, small gods, oldheads, suspects.
If you are to disbelieve these people(Mark Twain,Robert Underwood Johnson,Katharine Underwood Johnson,and George Westinghouse, Paderewski, Roentgen, the discoverer of x-rays and Tesla. All these men became friends and became famous.) then your back is against the wall.
If you have the audacity to not believe then you are up against the many and mighty pens of these people. And that makes you 'alone'.
Only the foolish argue with history.
I don't see how can you be sure, if there is some added momentum...
I'm sure there are some guy here, who could prove to you by common science there isn't any. 
The trick is produce slow energy, like we use these days, from the highly excited ejective output that is easy to do.
