Abstract
A device for generating substantially vertically-reciprocating motion uses a plurality of chambers in substantial vertical alignment. Each chamber has an air pocket and a buoyant member which floats at the air/water interface, and such air pockets expand and contract upon receipt of additional amounts of air from below and release of some of the air, usually to a chamber above. As the air pockets expand and contract, the interfaces are raised and lowered, and the buoyant elements are raised and lowered with the interfaces. A method uses such device to generate such reciprocating motion, which optionally may be used to drive electric generators.
Claims11
A device for generating substantially vertically-reciprocating motion when in a substantially liquid-loaded posture, comprising:
- a first and a second chamber;
- a first and a second buoyant element;
- and
- a gaseous-material conduit open to said first chamber;
- said first buoyant element being disposed within said first chamber and being comprised of a first buoyant member and a first downwardly extending piston member affixed to said first buoyant member,
- said second buoyant element being disposed within said second chamber and being comprised of a second buoyant member and a second downwardly extending piston member affixed to said second buoyant member,
- said first chamber being open to fluid flow below said first buoyant member and being open to fluid flow above said first buoyant member through a first valve having a first fluid-release point,
- said second chamber being disposed vertically above said first chamber, being open to fluid flow below said second buoyant member and being open to fluid flow above said second buoyant member through a second valve having a second fluid-release point.
A method for generating substantially vertically-reciprocating motion using a device having a first and a second chamber, a first buoyant element comprised of a first buoyant member and a first downwardly extending piston member and a second buoyant element comprised of a second buoyant member and a second downwardly extending piston member, said first and second buoyant members disposed respectively within said first and second chambers, a gaseous-material conduit open to said first chamber, said first chamber being open to fluid flow below said first buoyant member and being open to fluid flow above said first buoyant member through a first valve having a first fluid-release point, said second chamber being disposed vertically above said first chamber, open to fluid flow below said second buoyant member and from said first fluid-release point, and being open to fluid flow above said second buoyant member through a second valve having a second fluid-release point, comprising the steps of:
- (preliminary step 1) submerging said first and second buoyant elements and said first and second chambers in a liquid;
- (preliminary step 2) providing a first gaseous-material pocket above said liquid in said first chamber, said first gaseous-material pocket and said liquid forming a first air/liquid interface, whereby said first buoyant element floats at said first air/liquid interface;
- (preliminary step 3) providing a second gaseous-material pocket above said liquid in said second chamber, said second gaseous-material pocket and said liquid forming a second air/liquid interface, whereby said second buoyant element floats at said second air/liquid interface;
- then
- reciprocally expanding and contracting said first and second gaseous-material pockets and raising and lowering said first and second air/liquid interface and said first and second buoyant member by the repetitiously performing the sub-steps of
- (sub-step 1)releasing delivered gaseous material from said gaseous-material conduit to said first chamber, whereby said first gaseous-material pocket expands, said first air/liquid interface is lowered and first buoyant element is lowered together with said first air/liquid interface;
- (sub-step 2) releasing delivered gaseous material from said first gaseous-material pocket of said first chamber to said second chamber, whereby said first gaseous-material pocket contracts, said first air/liquid interface is raised and first buoyant element is raised together with said first air/liquid interface, and whereby said second gaseous-material pocket is expanded, said second air/liquid interface is lowered and second buoyant element is lowered together with said second air/liquid interface;
- and
- (sub-step 3) releasing delivered gaseous material from said second chamber, whereby said second gaseous-material pocket contracts, said second air/liquid interface is raised and second buoyant element is raised together with said first air/liquid interface.
