Abstract: A method for harnessing wave energy includes providing a vehicle to a body of water, the vehicle. The method includes submerging the vehicle to a depth in the body of water. The method includes operating the motor-generator of the vehicle in the first quadrant of the motor-generator. The method includes detecting a phase of a wave in the body of water based information from the processor of the detected phase. The method includes orienting the vehicle to lag the phase of the wave based on the detected phase of the wave. The method includes synchronizing an inertial acceleration of the vehicle to movement of the wave. The method includes switching the motor-generator to the second quadrant for generation mode to convert energy from the movement of the wave to electrical energy. The method includes storing the energy from the wave in the rechargeable battery source.

Abstract: A method for producing a syntactic foam for high-pressure environments includes providing a housing having a void volume. The housing may include an inlet and an outlet to the void volume of the housing. The method includes injecting a plurality of microspheres comprising glass into the housing. The plurality of microspheres include a first set of microspheres comprising an average diameter ranging from 5 microns to 150 microns. The method includes agitating the housing to settle the plurality of microspheres within the housing. The method includes injecting a resin from the inlet of the housing to the outlet of the housing to fill voids between the plurality of microspheres to form a resin-microsphere matrix. The resin may have a viscosity less than 100 centipoise. The method may include curing the resin-microsphere matrix in the housing to produce a cured composition.
