Inertial hydrodynamic pump and wave engine

A method for converting wave energy, comprising:

• generating electrical energy from a wave engine in a body of water, the wave engine comprising an upper bulbous portion which rises and falls under an influence of a body of water, the upper bulbous portion comprising a fluid collection reservoir, the wave engine comprising a hollow tube coupled to the upper bulbous portion and having a bottom opening at a lower end and a top opening at an upper end, the fluid collection reservoir fluidly coupled to the upper end of the hollow tube, the hollow tube configured to eject a fluid through the top opening and into the fluid collection reservoir in response to an increasing pressure within the hollow tube, the wave engine comprising an electrical energy generator for converting an energy of a portion of the fluid collected in the fluid collection reservoir into electrical energy, and the wave engine comprising a conduit extending from the fluid collection reservoir to the hollow tube.
