I've been playing with the power regeneration feature for the past few days trying to squeeze as much e/sec as possible into a 5x5x5 cube. The best I can get is 9520.4 e/sec. I've decided I have an efficent enough design already, but I've heard that it's possible to get around 10,000. Since there arn't very many posts about this subject, I decided to ask what the highest possible regeneration rate in a 5x5x5 cube is.
