Buoyancy engine

A buoyancy engine comprising:

• a support frame;
• at least two pairs of reciprocating arrangements supported on said support frame, each reciprocating arrangement of the at least two pairs of reciprocating arrangements comprising:
• i) a fluid cylinder operatively filled with a fluid;
• ii) a float arranged within the fluid cylinder and defining a reservoir with an exhaust valve located at an upper portion and a charging aperture at a lower portion via which said float is chargeable with atmospheric air;
• iii) an air injection assembly comprising a pump and an injection conduit, the pump linked to the float so that said pump draws the atmospheric air when the float descends and charges said drawn atmospheric air via the injection conduit when the float ascends;
• iv) a force multiplier assembly supported on the frame and configured to apply mechanical advantage between the float and the pump;
• and
• v) a power take-off linked to the float and configured to transfer energy from the float as said float ascends within the cylinder;
• a flywheel arranged on the support frame and coupled to each of the respective power-take offs;
• wherein each pair of the at least two pairs of reciprocating arrangements are opposedly arranged with the floats of each pair of the at least two pairs of reciprocating arrangements linked in a reciprocating manner;
• and
• wherein each air injection assembly of each pair of the at least two pairs of reciprocating arrangements is arranged to inject the air into the float of an adjacent reciprocating arrangement of another pair of the at least two pairs of reciprocating arrangements via the charging aperture of the adjacent reciprocating arrangement, to facilitate continuous actuation of the flywheel as the engine operates.
