I was just part of a tour group in the Hall of Justice (the new one in Washington, DC, financed by Batman) when I happened to overhear an intercepted message: Sinestro was deploying a device that would render all magnetic field on Earth useless.
Since we generate electricity by spinning turbines by various means that turn magnets around a wire, I am wondering what options we’ll have. Solar power? Steam engines? Any other way to make electricity that don’t rely on magnets?
