Apparatus for converting wave motion on a body of water into electrical power
View Patent ↗Apparatus for converting wave motion on a body of water into electrical power includes an electrical power generating system. The system includes a floatable housing. An electrical power generating unit is disposed within the floatable housing. The electrical power generating unit includes two spaced apart wheels which are connected by a drive element, and at least one generator for generating electrical power. A weight is connected to the drive element. When the system is tilted by wave motion, the weight moves toward the lower wheel, thereby turning the wheels and generator(s) and creating electrical power. In an embodiment, two weights are combined to provide drive element movement in a single direction. In another embodiment, the weight travels along a track which has two upturned ends.
1. An apparatus for converting wave motion on a body of water into electrical power, comprising:
an electrical power generating system including:
a floatable housing;
an electrical power generating unit disposed within said floatable housing, said electrical power generating unit including:
a first wheel;
a second wheel spaced apart from said first wheel;
a drive element rotatably connecting said first wheel and said second wheel;
a weight connected to said drive element;
an electrical generator rotatably connected to said first wheel so that when said first wheel rotates said electrical generator rotates;
a track disposed between said first wheel and said second wheel, said track having a first upturned section adjacent said first wheel, and a second upturned section adjacent said second wheel;
said weight movable along said track; and,
wherein said electrical power generating unit is configured to tilt due to wave motion such that one of said first wheel and said second wheel becomes lower than the other of said first wheel and said second wheel, said weight moving along said track and entering said first upturned section when said first wheel becomes lower than said second wheel, and said weight moving along said track and entering said second upturned section when said second wheel becomes lower than said first wheel;
said electrical power generating unit not having a stop to stop motion of said weight.
2. An apparatus for converting wave motion on a body of water into electrical power, comprising:

said first wheel having a first axis, and said second wheel having a second axis;
said first upturned section defining a first arc all points of which are equidistant from said first axis of said first wheel; and,
said second upturned section defining a second arc all points of which are equidistant from said second axis of said second wheel.
3. An apparatus for converting wave motion on a body of water into electrical power, comprising:
an electrical power generating system including:
a floatable housing;
an electrical power generating unit disposed within said floatable housing, said electrical power generating unit including:
a first wheel;
a second wheel spaced apart from said first wheel;
