Wow... that's an interesting idea Taking a system carefully designed to maximize power transmission across the country, and only sending power in bursts seems rather an odd design choice. You'd need to beef up all the transmission lines and transmission gear by a few orders of magnitude in current and/or voltage to make something like that possible. I'm not sure there's enough steel, aluminum, copper and insulators available to make that happen. How would you store gigajoule "packets" of energy?
