The first end (28) of heat pipe (26) and a second end (30) form a respective first condenser (32) and a second condenser (34). An evaporator portion (36) is disposed between the ends (28,30). The first end (28) has an air manifold (42) therearound. The second end has a liquid manifold (48) therearound. The heated air from the air manifold (42) is provided to a power generation device (22). The power generation device (22) receives heated air from the air manifold (42) which is expanded in a turbine (68) to extract mechanical work therefrom. The turbine (68) may be coupled to a generator (78) for generating electrical power in response to the mechanical energy.
