yes, the kinetic energy
the *changing* magnetic field
it's difficult to even say which one is which, is kinetic energy a changing magnetic field or is a changing magnetic field kinetic energy?
this "gravitational potential energy" which is the spook in the middle of this equation, is the energy that is carried by an electromagnetic field, that literally enables you to spin a wheel on one side, and a loop of wire with a coil on each end and you can transfer that kinetic energy directly as spin (given good geometric arrangement) to another, sans the resistance loss of the resistance of the loop of conductor between
what's interesting, to me, is that though the change of the polarity has a kind of inertia (which is proportional to resistance) it does not have a time of travel, only a limitation based on the medium the current flows through, which gives you resistance
resistance creates heat in the conductor but heat can also alter the flow of kinetic energy via newton's equal and opposite
this is why it's an absolute travesty that we still don't have public access to tesla's papers because there is good reason to believe he mostly figured out how to directly take that field potential out of the earth and directly generate current
and this shouldn't be amazing because in fact, earthquakes mostly happen via piezoelectric action caused by electrons thrown at us by the sun and caught in the poles of the earth's magnetic field
with the way that this magnetic field is weakening at this time, as a rotating field oscillation that passes every ~6000 years through 90 degrees from the centre of the galaxy, if humans could just figure out how to use the endless energy that is currently on in the process of going massively hockeystick to protect ourselves from the earthquakes, storms and volcanoes that this weak magnetic field is also going to induce
i didn't mean to interrupt the discussion, per se, just that my models of energy and motion and matter have been greatly impacted by recent understanding about how magnetism and electrons and protons flow around the solar system and galaxy and how it affects the weather, especially
but that's massive amounts of energy, i mean massive, i mean retarded amounts of energy, and in normal times it's enough to run all the machines, but in these times it could launch us to deep space
