Kurzbeschreibung des Verlags

What do you do when you are surrounded by water-but cannot drink it? This practical guide focuses on one problem: producing usable fresh water from seawater and other saline sources when a normal water supply is unavailable. Instead of presenting one "perfect" device, the book explains 20 different desalination systems, from extremely simple improvised setups to more advanced engineering solutions. You will see how the same basic physical principles can be applied with different materials, energy sources, and levels of technical complexity. Inside, you will learn about: - ground and container-based solar stills;- bottle-based passive systems;- fire-heated stills and improvised kettle setups;- vapor lines, condenser coils, and water-cooled condensers;- basin, double-slope, wick, and cascade solar stills;- remote-condenser designs;- multi-effect heat-recovery systems;- humidification-dehumidification (HDH);- manual reverse-osmosis watermakers;- source-water prefiltration, brine management, maintenance, and troubleshooting. The emphasis is not merely on copying diagrams. The book explains why each system works, what each component actually does, which parts can be improvised, and which specialized components cannot realistically be replaced with random materials. You will also learn how to choose between passive solar systems and active heating, improve condensation instead of simply adding more heat, prevent cross-contamination between the saline and clean sides of a system, manage concentrated brine, avoid dangerous pressure buildup, and measure actual output instead of relying on theoretical estimates. Some designs require little more than sunlight, plastic sheeting, and a container. Others use metal tubing, heat exchangers, controlled airflow, or specialized membranes. The goal is to understand enough of the engineering to choose the method that fits the resources, weather, time, and equipment actually available. Written for sailors, boaters, coastal campers, survival-minded readers, preparedness enthusiasts, and anyone interested in independent water production, this book combines field improvisation with practical engineering principles. You may never need all 20 systems. The value lies in understanding enough of them to recognize the best workable solution when conditions are no longer ideal.
