Would it be possible to recycle water that has run through a turbine back up and around again using a ram pump, essentially creating a closed loop water engine? Has anyone heard of such a thing? I've done some searching on the tubes, but haven't found anything yet.
Another half-baked idea is to somehow introduce grey water and filtration into the equation. It would cease to be a closed loop, but maybe better for different applications.

How does that sailor get water from the ocean, because he can't always take enough water with them, or the stored water becomes sickly.

Sailors in the 1700s primarily obtained water by filling large wooden casks at ports, supplementing this with collected rain, and rationing it strictly.
Distillation may be the only way that will work for you.
Yeah I'm considering destillers. At least the limitations are pretty inarguable. I know exactly what will evaporated and what I need to physically filter.
1700s sailors were built different. Lol. Most modern boats have a BEEFY RO system. (That's why I chose RO instead of destilling) Plus any other add-on filter they like. I'm looking very critically at the katadyn survivor 40E. It's over built and over priced for ground water. But it's built to be used as a complete system. The company expects that their customers will drink the water straight out of the system. They can't afford to cut corners and play with false claims because they'd end up with very sick, lawsuit-happy, customers. But apparently it a go-to in the long distance ocean traveling group when storage is only a temporary solution. You can repair most the parts yourself with common tools and such. They generally use an RO system to purify sea water. Dump it in a holding tank and test it on boat. If it tests good they put it in the main tank to drink. The only thing they have to be concerned about is oil and red tide. And those can be seen visually in the water.
