if you don't want the electrode from melting the pscn simply place the pscn one pixel away from the elctrode, in the opposite direction it's arcing to, or for more protection, add a layer of PUMP or GPMP, because they don't conduct heat.
As for battery, i can't think of one single use for indestructible battery
The only real use SING has is that it can make self destruct machines, by sucking in other particles. Pushing them away however? probably not as many uses __________________________________________________
