why does Most electricity generation method involve spinning a turbine?

768 viewsOtherTechnology

Are there other methods(Not solar panels) to do it that doesn’t need a spinning turbine at all?

the laws of electromagnetism describes the magnetism and electricity as two faces of the same coin. the relation is governed by one motion of one versus the other. that is, a moving electron becomes a magnet and a moving magnet makes electrons move (electricity). therefore you can move wires in the vicinity of a magnet and make electricity inside said wire (generation), or you can move the magnet around the wire (magnetic braking, basically the same thing), or you can alternate current in one wire and make electricity in another nearby wire (wireless charging). Richard Feynman said it so cleanly in an old video that to make some wires move here you have to move some wires over there, where there could be miles away.

here’s the answer to the question. you want to make a very powerful and expensive object to move but you also don’t want it to run away.

This is all classical physics.There is another way to generate electricity that does not require motion and that is via quantum mechanics and the photoelectric effect–solar panels. those don’t need physical motion. but again if you want to move the energy somewhere else, you need huge AC voltages and in order to make that you need…..powerful rotating and expensive objects that don’t run away.

can you do all this without wheels, yes. you can collect heat at one end of a cylinder to expand the contained gas and use that motion to do the work you need. but then you need the piston to come back for which you need a ……..crankshaft oops that’s a just a wheel with wedges wrapped around it. you don’t need rotation to work with energy transfer, but you need it if you want to do it again…and again…and again.

tldr electric generation requires motion and motion moves your generator machine away. to get it back you need rotational motion. the obvious solution is a wheel that doesn’t roll on the ground. this means turbines, rotors, propellers, shafts etc.
