A closed dual-bladder wave energy system that is capable of capturing a continuous supply of energy derived from wave movements for nearshore implementations. Rather than employing an onshore bladder in communication with an offshore bladder, and rather than focusing on capturing more incremental potential energy derived from tidal movement, the system accomplishes continuous captures potential energy from waves via a dual-bladder system employed offshore. Fluid within the system translates between a first offshore bladder and a second offshore bladder based on a pressure differential between a crest and a trough of a wave external to the system. By utilizing compliant bladders, the system is capable of capturing energy even during inclement weather conditions without the risk of faults resulting from strong waves. As such, the system provides for the efficient and effective capture of potential energy from waves in any weather condition and in any water environment that experiences waves.

A peristaltic pump system has a pump tube and a pump rotor engaging the pump tube. The pump rotor is drivable to rotate to move a pump fluid through the pump tube from a pump inlet to a pump outlet. A motor drives the pump rotor to rotate. The motor includes a motor tube and a motor rotor to be driven to rotate by a motor fluid moving through the motor tube from a motor inlet to a motor outlet. A urine treatment system and method are also disclosed.

A hydrostatic pressure to kinetic energy conversion system comprises a hydraulic head water column having a lower end which diverges to a pair of pressure channels. A valve system interfaces the water column and the pressure channels so that hydrostatic pressure from the water column alternately pressurises each channel. The system further comprises racks forced by pistons to act oppositely to rotate a driveshaft therebetween. Furling bladders within the channels forcibly unfurl under pressure to force the pistons. Proximal ends of the pistons may comprise sufficiently small diameter for envelopment by the furling bladders.
