An improved power plant employing a combination of compressed air storage and saturation (simultaneous heating and humidification) of compressed air is disclosed. The power plant includes a combustor which provides hot gas for driving a turbine. The turbine is used in conjunction with a generator to generate electrical power. The power from the turbine is accessible by a compressor system during low power demand periods. The compressor system is used to compress air which is stored in an air storage chamber. The compressed air from the air storage chamber is used by the combustor during high power demand periods, while the compressor system is shut down, to provide compressed combustion gas to the turbine. To enhance the efficiency of the plant, while further lowering the capital cost of the plant, a saturator is positioned between the storage chamber and the combustor. The saturator receives compressed air from the storage chamber and simultaneously heats and humidifies it.

A device for controlling the growth of organisms in the cooling water inlets (7a and 7b) in outboard or stern drive motors. The device comprises of a resilient collar (1) that is placed over the cooling water inlets (7a and 7b) in such a way as to trap a small amount of water (9) inside of and immediately adjacent to the cooling water inlets (7a and 7b). On one side of the collar (1), near one inlet (7a and 7b), a cavity (6) for holding and releasing a treatment chemical (8) is provided. The water (9) trapped in the cooling water inlets (7a and 7b) slowly dissolves the treatment chemical (8), releasing a biocide, thus inhibiting the growth of the targeted organism. A handle (2) is provided so that the collar (1) can be readily installed and removed from the stern of the boat without removal of the boat from water (9).
