Q

Which of the freshwater generators listed below is operated without a source of heat?

🔍 Key Concepts

• Difference between thermal and non-thermal freshwater generation systems • How evaporation/condensation processes depend on added heat versus pressure changes • Basic principle of reverse osmosis (pressure-driven membrane separation)

💭 Think About

• For each option, ask yourself: does this design rely on boiling/evaporating seawater, or on pushing water through something? • Which of these types would logically need a heating source, such as steam or waste heat from the main engine? • Which system could produce fresh water even if you only had mechanical power (pumps) but no steam or waste heat available?

✅ Before You Answer

• Identify which types are evaporators (using heat to make vapor that later condenses) • Identify which type uses a membrane rather than a boiling/flash chamber • Confirm which option could still operate on a cold engine, provided you had electrical or mechanical power for pumps only
