FAQ Day Night Solar Time Tic Energy Power :: The Riftbreaker

1) Cut your energy draw in k (thousands) in half. So a 2000 power draw or 2k power draw is now 1k power draw. 2) Add _4_ zeroes. So 1k is now 1,000k. You should have at least 1,000k energy storage. 3) Test your conclusion. 1,000k storage / 2k power draw = 500 tics of time to fix things if something goes wrong.
