Abstract: An internal combustion engine heat energy recovery system (1) comprises a first heat exchanger (20) arranged in heat communication with at least one heat energy source of an internal combustion engine (10) and with a working fluid of the system (1) for the transfer of heat energy from the heat energy source to the working fluid of the system (1). A turbine (30) is arranged in fluid communication with the working fluid heated in the first heat exchanger (20) for the expansion of the working fluid to produce shaft power. A second heat exchanger (40) is arranged in heat communication with the expanded working fluid to remove waste heat therefrom and transfer it to an external source such as the atmosphere. A first compressor (50) is arranged in fluid communication with the working fluid exiting the heat exchanger for increasing the pressure of the cooled working fluid prior to its entry into the first heat exchanger (20). The working fluid of the system is a substantially supercritical fluid.

Abstract: A power generator assembly for using kinetic energy from a flowing fluid to generate power. The power generator assembly includes a blade assembly and a generator. The blade assembly has a head end for facing oncoming flowing fluid, a tail end spaced from the head end for facing in the direction of flow of the fluid, and a rotational axis extending between the head end and the tail end. The blade assembly includes a blade arrangement which is arranged in generally helical fashion about the rotational axis, and at least one mounting formation connected to the blade arrangement. Each mounting formation is adapted to permit mounting of the blade assembly for rotation about its rotational axis, so that in use fluid flowing past the power generator assembly interacts with the blade arrangement to rotate the blade assembly about its rotational axis. The generator is drivingly connected to the blade assembly for generating power in response to rotation of the blade assembly.
