Hello. I’m a new addition to the board, and if I’ve posted in the wrong place or this is otherwise unwelcome, please PM me and let me know. I’m a writer and I’m working on a science-fiction novel set on Mars in the distant future. I can gather most of the information on the planet, the requirements for living on it, and the theories on terraforming elsewhere, but I have one problem for which I would appreciate the input of more knowledgeable people. I have need for a plausible explanation on why half the world would be able to use electricity and the other would not. I have toyed with the idea of random electromagnetic pulses (or a constant electromagnetic pulse) that interferes with the majority of electrical devices and equipment, though as I understand it, older and solid state technology might be immune to electromagnetic pulse. My question, I suppose, is what explanation in our modern technology would explain the occurrence of repetitive electromagnetic pulses? I’m foregoing nuclear explosions, and I would prefer as natural a phenomenon as readers would find believable. Theory is quite welcome if nothing in our reality could cause such events. Any response is welcome. If the novel is published, I would be happy to include people in a “special thanks” page for contributions that help me create this world. Thanks, everyone.
