Some numbers to compare:<p>They got 20uN with a 700W magneton, that is 20uN&#x2F;700W = 0.03 mN&#x2F;KW. (Probably some energy is &quot;lost&quot; and the &quot;real&quot; efficiency is higher, but when you claim to break the physics law the measurements must be foolproof.)<p>The maximal theoretical output of a device that don&#x27;t break the currently accepted physics laws is 1&#x2F;c = 0.0033 mN&#x2F;KW. So this measurement is 10x bigger than the theoretical maximum.<p>The 18-month-to-Pluto calculation use 0.4 N&#x2F;KW = 400 mN&#x2F;KW, that is approximately one half of the maximum claim of any of this device family, but most experiments get much smaller results. The 0.4 N&#x2F;KW is 130,000x bigger than the theoretical maximum and 13,000x bigger than what they got in this experiment. So if a device with the same output of this experiment, the trip to Pluto will be much longer.<p>(Disclaimer: Just to be clear, I think this is only an experimental error.)
