Filtering sea water through shirt


Trigger Mike

Recommended Posts

I just read a news article where a kid from Indonesia was adrift for 49 days and filtered sea water through his shirt to lower the salt .  It did not say if he suffered kidney damage from it. Would it work? Would a shirt be enough?

"The teenager only had a few days worth of supplies and survived by catching fish, burning wood from his hut to cook them, and sipping seawater through his clothes to minimize his salt intake."

Sorry, the salt in seawater is dissolved and can't be "filtered" short of membrane (R.O.) type technology.  Clothing would remove only suspended particles too large to get through the weave.

If this were true, navys would have switched to this long ago and avoided those expensive distilling units.

Could also get good moisture content from fresh caught fish.

They said he used wood from the shack to make a fire to cook the fish. I guess he’s not fond of sushi. But cooking it would both lessen the nutritional value and dry it out (not to mention building a fire on a wood boat/raft/shack seems, at best, a little risky)
