It was just in response to OP\'s question really. It\'s more about an efficient use of space if you\'re restricted to that size, not about getting the most out of the number of blocks you have.
The highest output of power would be for all blocks to be part of a single entity, so a line, an L shape or 3D L, they\'re all the same. (As demonstrated in the screenshot directly above your post, 490 in a single line gave over 600,000 e/sec.)
Obviously you can\'t have just one grouping in your ship, so you\'d need multiple. As shown above, simply laying out many sticks of X amount long is actually not the best; we tried that, and while it gave a lot, it didn\'t have the best output.
Since your ship is likely not going to be one dimensional, unless you\'re being unconventional, there\'s a better pattern than sticks of power blocks alone.
