A system and method for moving water up a water column to achieve a sufficient pressure to overcome a reverse osmosis filter. The system includes a rigid outer column for receiving and holding water, with an inner, deformable hose located inside the rigid outer column. The hose has a one-way valve at a distal end of the hose to allow water to enter the hose and an outlet at the proximal end of the hose to allow water to exit the hose. A water-raising device to raise the water within the inner, deformable can include a system that moves sections of water within an inner lumen using a peristaltic motion to drive water upwardly through the inner lumen.

Systems for wave energy conversion that have components that can survive the harsh marine environment and that can be attached to fixed structures, such as a pier, and having the ability to naturally adjust for tidal height and methods for their use are presented.

The hose has a one-way valve at a distal end of the hose to allow water to enter the hose and an outlet at the proximal end of the hose to allow water to exit the hose. A water-raising device to raise the water within the inner, deformable hose includes a roller to selectively clamp the hose, and a buoyancy support attached to the roller. The buoyancy support is selectively inflated and deflated to move the clamp (and water inside the deformable hose) within the rigid outer column.

Systems and methods for use in capturing energy from natural resources. In one form, the systems and methods capture energy from natural resources, such as movement of fluid in a body of water, and convert it into electrical energy.

A two-body wave energy converter utilizing a linear, universal modular absorber. A linear module, contains a direct drive linear machine for converting linear mechanical motion into electrical energy. The linear module is connected between two oscillating mechanical bodies, exploiting their relative motion. A wave activated floating body follows the wave motion, while a reaction body is tethered to a mass on the seabed providing a stable kinematic reference in operational waves. In large waves, the mass on the seabed lifts, providing heave compliance to the whole wave energy converter reducing ultimate loads in survival wave conditions.
