A wave energy converter (1) has: a buoyant structure (2) which, in use, floats on water; a generator (18); a generator drive mechanism (38) on board the buoyant structure (2), the generator drive mechanism (38) having an rotational input drive shaft (20) and a rotational output drive shaft (36); a drive member (22) operably connected to the input drive shaft (20), the drive member (22) being moveable back and forth between a first position and a second position; a biasing arrangement (23, 26) for example a buoyant block acting on the drive member; and, a submerged element 4, 4′ which, in use, moves below the surface of the water out of phase with the buoyant structure (2), the drive member (22) being attached by a tether (28) to the submerged element (4). In use, when the buoyant structure (2) encounters a wave crest, the spacing between the buoyant structure (2) and the submerged element (4, 4′) increases and the drive member (22) is pulled towards the second position by the tether (28), and, when the buoyant structure (2) encounters a wave trough, the spacing between the buoyant structure (2) and the submerged element (4, 4′) decreases and the drive member (22) is urged towards the first position by the biasing arrangement (23, 26). The back and forth movement of the drive member (22) between the first and second positions causes the input drive shaft (20) to rotate and, thereby, causes the output drive shaft (36) to rotate. The submerged element (4, 4′) is preferably a heave plate. The invention also comprises a heave plate for a submerged, partly submerged or floating structure.

A kinetically-powered wrist-worn electronic device is apparatus that includes a portable computing device, a wrist strap, a weight, and a generator. The portable computing device runs an operating system responsible for managing and distributes computing resources to various application software on the present invention. A wireless communication module accesses a wireless local area network (WLAN) or a wide area network (WAN) and enables the portable computing device to communicate with external computing devices. The wrist strap secures the portable computing device onto the wrist of the wearer. The weight uses a swinging mass which is designed to oscillate whenever the wearer moves his or her wrist. The generator harnesses and transforms the kinetic energy generated by the oscillating weight into usable electrical energy to power the portable computing device. The electrical energy is stored in a portable power which transfers the electrical energy to the portable computing device.

The pneumatic roadway energy recovery system generates power from the weight of vehicles, pedestrians and the like traveling on a roadway surface. The pneumatic roadway energy recovery system includes a plurality of pneumatic pumps in fluid communication with one another and that are arrayed beneath a roadway surface. The pneumatic pumps are in fluid communication with a storage tank. The vehicles, pedestrians and the like traveling on the roadway surface compress the plurality of pneumatic pumps as they pass over the pumps, generating pressurized air, which is received by and stored in the storage tank. Preferably, a turbine, such as a Pelton wheel or the like, is in fluid communication with the storage tank. Selective release of the pressurized air in the storage tank drives the turbine, which, in turn, is connected to an electrical generator for generating usable electrical power.
