How do boats make fresh water?
How do boats make fresh water? All watermakers designed for small boats and yachts rely on essentially the same technology, exploiting the principle of reverse osmosis: a high pressure pump forcing seawater through a membrane that allows water but not salt to pass.
How did the Titanic get fresh water?
In Titanic's case she had evaporators that turned seawater into fresh water suitable for the boilers - in fact distilled water, as any salts or other compounds or gases such as carbon dioxide and air can cause corrosion in the steam system.
What is the biggest problem with desalination?
What are the environmental impacts of desalination? Most forms of desalination are energy-intensive. Desalination has the potential to increase fossil fuel dependence, increase greenhouse gas emissions, and exacerbate climate change if renewable energy sources are not used for freshwater production.
How did old sailors get fresh water?
