Notice that they are getting microwaves, but the device is fed at GHz frequencies, so how do we know that what they are detecting isn't just leakage (or a harmonic) of what they put in? Even if it's real, it's still no guarantee of free energy, because they put energy in and the amount they get out is tiny by comparison (I assume). >Jones, They are electrically moving the equivalent physical position of a >mirror at 5% of light speed back and forth over a nano meter range to >separate the virtual particle pair and make them real.
