A Redstone Energy Cell (from Thermal Expansion) continuously emits energy according to the rate set in its GUI as long as it contains MJ. If the Buildcraft machines connected to the energy network aren't doing anything, eventually the first conductive pipe connected to the Cell will explode. By comparison, an IndustrialCraft MFE stops emitting EU until a machine connected to it needs EU, and this makes it very easy to use without problems. I'd like to set up my BC power network to be as well-behaved as my IC power network.
I was able to get an Autarchic Gate to toggle the cell on/off using the 'Inventory is Full' setting when beside a machine, but this would require a Gate beside every machine connected to the power network. I would rather use a single gate to turn the cell on or off if any machine connected to the cable is working, like a 'Load Connected' setting for the gate. How can I do that?
