Mack, I think we're getting into some semantics here. This discussion comes about, please recall, from the claims that a certain device / machine could provide power without any source of energy. It dubiously claimed magnet reversed polarity and other pseudo-scientific mumbo-jumbo as to how it was supposed to work. The machine and others like it simply contravene fundamental laws of nature or physics, and are obvious cons. What I was endeavouring to point out was, as you acknowledge, magnetism is not a source of power, it is a means of converting one sort of power or energy to another, electricity to mechanical power or vice-versa. I've already said this a couple of times and given examples, so your not claiming something that I haven't already admitted. You go on to state magnetism is a just a field, yes, but in a permanent magnet where does this field come from? It's from matter, that has been at some time, magnetised. Magnetic fields have to arise either from magnetised matter (which of course only applies to certain forms of matter - eg iron) or from electrical currents. I think it's rational for me to state that this particular magnetic field comes from the state of the matter in which the magnetism resides? In regard to gravity, then again I'd have to argue my point here. Gravity is exactly a state of matter (and of energy). (I am here treating matter and mass as interchangeable conceptions, though strictly in physics there is a subtle difference). According to Newton's theories it is an intrinsic property of mass creating a force directly related to the amount of the mass, and even Einstein would agree that gravity is a property of mass, though he doesn't see gravity as a force, but a disturbance or curvature in space time due to unequal distribution of that mass. So when you write "that's a bit like saying gravity's only useful if you want something to hit the ground when you let it drop", Yes, that's exactly what I am saying. Indeed gravity, as a store (not a source) of energy, is only useful when some preceding action allows gravity to cause an acceleration on an object. eg, raising the apple and then letting it fall, creating useful energy from water which the sun has kindly elevated for you, or on a bigger scale, the energy which we might be able to utilise from the action of the gravity of the sun or moon on our oceans causing the tides - (but the source of tidal energy isn't the gravity of these objects but the rotation of the Earth, which gradually loses angular momentum as a consequence, and the orbit of our moon around the Earth, the Moon consequently losing orbital momentum and gradually retreating from us) - or on a more universal level, it's certainly "useful" for holding us to the ground and the oceans in the seas and our orbit around the sun. But thanks for your contribution, such challenges are really useful in getting one's thoughts into some rational order. Cheers, JKM
