System for harvesting water wave energy

Title: System for harvesting water wave energy

Abstract

A generator for harvesting energy from water in motion includes a sheet of a hydrophobic material, having a first side and an opposite second side, that is triboelectrically more negative than water. A first electrode sheet is disposed on the second side of the sheet of a hydrophobic material. A second electrode sheet is disposed on the second side of the sheet of a hydrophobic material and is spaced apart from the first electrode sheet. Movement of the water across the first side induces an electrical potential imbalance between the first electrode sheet and the second electrode sheet.

Triboelectric nanogenerator for harvesting energy from water

Patent Wang, Zhong Lin; Lin, Zong -Hong; Cheng, Gang

A generator for harvesting energy from flowing water is disclosed. The generator harvests electrostatic energy as well as mechanical kinetic energy from the flowing water. In one aspect, the generator includes a plurality of blades arranged in a radially outward fashion. Each blade includes an electrode and a surface layer for receiving flowing water carrying triboelectric charges. The flowing water affects a flow of electrons between the electrode and ground. In another aspect, the generator includes a first member with a first electrode, and a second member coupled to the first member about an axis. The second member includes amore »« less

Electrochemical systems configured to harvest heat energy

Patent Lee, Seok Woo; Yang, Yuan; Ghasemi, Hadi; ...

Electrochemical systems for harvesting heat energy, and associated electrochemical cells and methods, are generally described. The electrochemical cells can be configured, in certain cases, such that at least a portion of the regeneration of the first electrochemically active material is driven by a change in temperature of the electrochemical cell. The electrochemical cells can be configured to include a first electrochemically active material and a second electrochemically active material, and, in some cases, the absolute value of the difference between the first thermogalvanic coefficient of the first electrochemically active material and the second thermogalvanic coefficient of the second electrochemically activemore »« less
