Safety is the First Priority
The use of fuses strategically placed -- so as to not get in the way of fostering an oscillating current throughout an overunity circuit -- is good advice in case you want to build this circuit...


...or any of its variations.
Some locations within these circuits are not advantageous for the placement of resistive elements since current is being fostered there. But some locations are advantageous for elevating resistance (within limits) since resistance at those locations can enhance the growth rate of overunity.
These oscillating currents are not to be confused with alternating currents spawned by oscillators, for oscillating currents are the fourth type of current described by Eric Dollard in his treatment of the subject.
