To date, the success of these people has been ZERO.
The cases I have had the opportunity to review - the individuals misinterpret, misidentify, mis-characterize or don't understand their 'lab work' or their 'device'.
Whether it was misinterpreting the 'peak' versus average or RMS (Root Mean Square) value of a waveform as read on a voltmeter as opposed to integrating that waveform on a digital oscilloscope and taking into account such factors as 'phase angle' (or power factor) - or incorrectly performing mathematical calculations to calculate efficiency of their 'device' -
- they turn out to be either wrong or hiding details in order to convince investors in the 'possibility' of their device
