After a bit of thought I came to the conclusion that the silver drop will be shot in a direction that is directed away from the capacitor bank. This direction is along the length of the two electrodes in a manner similar to the path expected for the projectile of a rail gun. You can visualize this by realizing that the current carrying pair of wires that are a portion of a loop will repel each other and attempt to become oriented into a round loop. This demonstrates the desire for a current carrying configuration to achieve the minimum inductance.
The energy stored within an inductor is calculated by E=1/2*L*I^2. When the inductance(L) is reduced while holding the current(I) constant mechanical work is generated to maintain the energy(E) conserved. This is the source of the force that drives the drip and any conducting plasma outwards. An inductive loop will make every effort to keep its current constant if it is confined as a fixed shaped inductor. And, if the silver vapor attempts to open the circuit by dispersing, and thus increasing its dynamic resistance, the voltage appearing across that plasma vapor will rise rapidly. The net voltage can become many times greater than the original source(5 volts) which might explain some of the high energy radiation seen. Of course the duration of the high voltage spike is important as well and must be considered if a reasonable model of the total system behavior is constructed. Mills and team have spent a great deal of effort to control the inductance of the mechanical design of their generator. The size of the conductors leading to the electrodes is impressive as well as the very low inductive connecting straps between the energy storage capacitors. This evidently is required to ensure that a large amount of energy is deposited into the drips for a short time duration.
