In this work, we consider the possibility of energy storage enhancement in electrostatic capacitors using the compensational method. The essence of the proposed approach is the use of inductive voltage Vind to partially compensate the electrostatic voltage q/C produced by the electric charges on the capacitor plates. We hypothesize that it may be possible to increase the amount of charge stored on the plates before the breakdown and increase the energy stored in the capacitor using the compensational inductive voltage. There are several possible scenarios of manipulating the inductive voltage to increase the amount of energy released via the discharge. We also consider several electro-magnetic capacitors for practical utilization. Potentially, the energy per volume stored in a simple parallel plate capacitor may exceed that of gasoline. The physical limits and technological shortcomings of the proposed approach are also discussed.
