SELF PROPELLED ICEBERG

The concept of a self propelled iceberg is developed using a thermodynamic cycle similar to Ocean Thermal Energy Conversion (OTEC). Calculations show that a propulsion pod developing 2.224 megaNewtons (500,000 lb) thrust requires a power of 6.8 megaWatts assuming an ideal cycle. Propeller diameter is 23 meters. For a transit from Antarctica to Los Angeles, 1.6 per cent of the iceberg is converted to water as a result of power extraction. An alternate concept using electrical propulsion is briefly presented. The thermodynamic cycle based on anhydrous ammonia is discussed.
