Let's say I had an object in space, a ring in this particular case, who was using light energy to spin itself up. The ring was built with a reactor inside of it along with a passenger/observer (we'll call the inside observer Bob for now). Bob, the ring, and the reactor are pretty much indestructible for arguments sake. The reactor produces 1000Mw of electrical energy. But the cool part about the rings reactor is that it is supposed to be able to emit the energy out past the ring. What happens to energy being sent from the ring out towards the Energy reciever? Bob looks at the readings of the reactor which should function normally due to his frame of reference, or is that wrong? What does the outside world recieve? What happens to electrons spinning around atoms at close to the speed of light? Are they slowing down the closer you get to the speed of light? Lets say you had an atom who had electrons rotating around it at 5% the speed of light and you reached 99% the speed of light in your rotating ring. What happens during that last 5% of your moving up to speed? If mass increases the closer you get to the speed of light shouldn't the energy produced by a reactor also increase? It's protons and electrons now have more mass, what does that mean for atomic mass now? Not that I would but if I split an atom in this state wouldn't it's effects be greater? With electrical energy does that mean it'll take more energy to offset the balance between protons and electrons? Or would the effects of the offset be greater? I've got more weird follow up questions but we'll just stick with this for now.
