>>95104751mine is pretty basic, but I always loved the concept of a dyson sphere, just a big bowl around a star that harvests it's energy, will probably power your entire civilization for the next couple hundred years on it's own. (I'm assuming it won't be much more because that much energy might make your tech lvl explode, increasing your energy demands dramatically as well.) I know dyson swarms are more realistic though, and you still need to dismantle several solar systems worth of material to even build the thing, but still.
