@Wavewatcher Here is a link to a lecture containing the same words in a first year physics textbook (late 70's) I still have: http://www.phy-astr.gsu.edu/cymbalyuk/lecture22a.pdf
Energy is used (work is being done - the effect of force over time on the charge in motion) in deflecting (causing a change in angular momentum) a moving charge, single electron or not, when using potential difference between deflection plates to do so. I would agree and think we are speaking of two different effects. My impression from the diagram was that he was using fixed capacitors that is the charge on the capacitors does not change due to an external input. In which case the plates of the capacitors may be charged initially and the input removed not unlike two charged spheres. Now if work was performed on a charged plate then energy must dissipate however this is not the case and the charged state remains constant. I believe you are referring to an electron tube where the charge on the plates varies over time from a variable source in which case energy is dissipated through the standard mechanisms, ie I2R and leakage. Ok I just checked the link, I think I see the problem, http://www.phy-astr.gsu.edu/cymbalyuk/lecture22a.pdf, page 5 Work The electric force does work in displacing a charged particle The magnetic force associated with a steady magnetic field does no work when a particle is displaced I think the confusion lies around the terms deflect and displace, a change in velocity constitutes work however a change in direction does not. This may relate to the claim in question because if the charge on the plates is constant then the charged particle(electron) may change direction but not velocity, only velocity relates directly to Energy. However if the capacitor was an integral part of a larger capacitive system then we could be dealing with a partial charge imbalance in a parametric system involving the capacitance. You see this is one of those gray areas, did the field of the moving electron change the capacitance or did the changing capacitance move the electron? If so when and where?. At this point I can only speculate as to my knowledge this experiment has never been done before. As well most people become hopelessly lost in the dynamics of relatively simple parametric systems. Again i'm not saying anything works as claimed however intelligence is not defined by denial it is defined by the ability to solve the problem at hand. It may work, it may not however if I could make it work from my perspective then I don't really care whether it does or not. AC
