The exhaust gas of a Diesel engine, which flows from ships at an anchor in a harbor, cause environmental destructions in the harbor area. In order to protect from the environment from destructions, it is considered that a waste heat recovery system is very valid. The system generates electric energy from the waste heat of a Diesel engine of a ship, and saves the electric energy to batteries in the ship. When the ship is in a harbor, the saved electric energy is used in the ship without the operation of any Diesel engine generator. In this research project, we developed three Stilring engine generators. The 1st prototype engine was designed to get an effective output using the waste heat that has 400 degree C of temperature. The 2nd prototype engine was improved to reduce thermal losses based on considerations of experimental results of the 1st prototype engine. The 3rd prototype engine was developed with considerations of productivity. Also the related components, such as a high-efficient generator and a control system for charging to batteries, were developed. In order to prove the performance of the heat recovery, the system was carried to a cement carrier ship "Pacific Seagull". As the result, we confirm that the system is effective as a new energy technology.
