Name: Machine Energy Demand Tweak
Description: Back in IC1, your macerator, furnace, and so on, would refuse to run UNLESS it already stored enough energy for a full cycle (1 item process). This meant that it would not waste energy, (if say you were to remove the item while it has not enough power) but this is a minor detail.
This would have a second effect in IC2. Have you ever tried to run a macerator, with sound on, without quite enough power. (If you have, I want you to tell me if you still have the ability to hear.) The constant loop of, Power up, try to run, turn off, etc, which on it's own is O.K., but with sound, tends to deafen anyone nearby. Now, if we required it to stock enough power to run first, then I imagine this problem would go away. One thing to note is that unless your machine has enough power storage available, it would be unable to run. (overclockers here)
(also, fixing the sound volume issue would help)
