If the law of conservation is true, then when a cavitation void is forced to form, does surface tension pull free electrons until a state of equilibrium is achieved? Furthermore upon collapse of said void does Boyle's law play a factor? No posers please.

While a collapsing cavitation bubble get heated to temperatures high enough for the gas to glow, you are not going to get any free energy from such a device. It will always take more work to create the cavitation bubble than you can get back, despite the extremely high temperatures.
Boyle's law states that the product of pressure and volume is a constant in a gas at constant temperature. However, the temperature inside a cavitation bubble is far from constant, so the law does not apply.

No high temperature is formed when a propeller creates a cavitation in water. All ocean and lake water contains dissolved air, otherwise cavitation's could not form. Energy is dispersed in the form of shock, or sound waves in the water, this is how ships are detected by submarines and vise versa.
