Abstract

A device and method for converting ocean wave energy into electricity either on moored buoys or in small vessels. The device and method of the invention utilize a U-shaped tube in communication with a gas concentration cell. The U-shaped tube resides in a cradle or other support means, secured to the buoy or other base which imparts wave energy thereto. The U-shaped tube contains a combination of liquid and hydrogen gas. The rocking of the U-shaped tube creates varying gas pressure differentials, which deposits oppositely charged particles on parallel electrocatalytic electrodes located within the gas concentration thereby creating an electrical potential therebetween, according to the Nernst equation.
