found this…hmm…interesting…
anyone seen one???Less than 100$…by a frick*n penny…urgh…hate when they do that…
looks like a viable option though as a saftey item…
volume
.5 liter in 4-8 hours depending on the temperature. Thats not a lot of water.
not much water
You’d need a dozen of them to keep you hydrated.
But they don’t say ‘purifies sea water to fresh water’.
It says, ‘converts saltwater into a lifesaving drink’!!!
I’d like to know what the ‘lifesaving drink’ is?
It obviously isn’t water!
a margarita
seems kinda close to a 'rita
i did see one page some where on there that the product has 480 calories…
the syrup stuff you add has sugar…so kinda like a gatorade type drink afterwards???dunno…just happened across it…
Cool.
Cool, but…
Seems like this is only geared towards survival situations.

LOL!
it’s improved my chances on more than one occasion!
Survival drink
The SeaPack operates by pulling pure water out of sea water through a filter. It is called forward osmosis since it pulls water from the source instead of pushing water through a filter like reverse osmosis does.
The SeaPack accomplishes this by using a sugar syrup. The SeaPack is essentially a bag within a bag. The outer bag is shaped like an IV bag. It holds the seawater. The sugar syrup is placed into the inner bag of the SeaPack (via the green port) and the sea water is placed into the device via the red port. The inner bag is the filter.
The SeaPack is made for use in survival situations. The drink that is produced is essentially sugar water with a slight grape flavor. It is high in calories (for energy) due to the sugar that makes it work. It is lightweight and can easliy fit into your kayak. It is not made for camping and daily use. It is for when you drift out to sea and need something to help keep you alive.
Yes, it is pricey, but have you looked at the alternatives? A hand held reverse osmosis pump costs almost $800. Taking fresh water along is too bulky for just survival purposes. Anyone else have another option?
Someone commented that it doesn’t make that much for you to drink. All USCG approved life rafts come with one pint of water per person. Not per day, one pint period. A six person life raft comes with six pints of water and that’s all you get. Try surviving off of that.
The SeaPack is primarily used by off shore boaters that want to ensure that they have something to drink in the event that they have to abandon ship. We’ve sold a few to kayakers that fish in islands off the coast and are fearful of currents dragging them out to sea.
Please let me know if you all have any other questions.

Good info
… so if you put some ethanol in with the sugar water it would lower the osmotic pressure of the water further causing more water to flow through the membrane to attain equilibrium, increasing the yield of the system.
Sounds like a win-win to me 
There was a story of a kayaker loosing his water supply in a capsize and then getting stuck on a beach for several days of bad weather. Could have been life-threatening.
WQA Certified Water Specialist II
I was in water treatment for over 9 years, certified in basic water chemistry and in RO/ultrafiltration. Things to look out for:
• definitely for survival only. System is only good for 10 days after 1st use according to FAQ section of website, and is NOT reusable.
• slow production (.5 litre in 5.5 hours) in 60 deg temp water. I can’t speak fluently here (I’m a midwesterner), but I suspect avg. ocean temps are quite a bit lower than that. It appears that the production speed is lowered exponentially w/ temp.
• “independent testing” is highly suspect to me, as not one agency is listed. Respected sources like WQA, NSF or others should be sited if the tests are AT-ALL reliable. Not a single standard was listed. Vague references to “military” tests can be very misleading and deceptive. This fact alone is enough to make all claims UNRELIABLE.
• technology (IF accurate) is dependent on a highly-salted additive. Note that not all salts are bad, but they fail to identify any real details on the additive or the product. For the natural osmotic pressure to overcome seawater, the TDS of the additive would have to be in the 3-4000 range. For example, on a residential RO application, the osmotic pressure of 2000 TDS water at avg residential water pressure of 50 psi, will eliminate production. A high-pressure pump is required to overcome it. For water to move through their membrane, the additive must be 2-3 times the TDS of seawater, in my opinion.
This may end up being a worthy technology, but there are far too many questions that have gone unanswered. Maybe they simply rushed it out to market before the right testing could be secured, or maybe they’ve chosen to ignore (and mislead with exclusion of) negative test results by the proper agencies. An NSF or WQA certification mark would eliminate this possibility, but quoting “to EPA” standards gives no verification at all. I would say that this product, until verifiable, independent testing to accepted standards is available, is a crap-shoot at best. Yes, I would probably use it if stranded at sea and had nothing else available, but that’s not the issue here. The issue is which product do you choose ahead of time WHILE YOU HAVE A CHOICE. I’d say go with certified, (varifiably) proven technology.
Notice the previous post by a representative of the company or dealer. I’m no longer in the business (haven’t been out long), nor do I make a recommendation to a specific product, so beware of any attacks on MY credibility here.
Hope this info helps . . . .
full disclosure please

If you have any connection with this company it is customary to say so. OTOH if I were carrying a RO pump I'd have this as a backup.
Fresca
There is a lifesaving drink. Perhaps it turns seawater in Fresca.
Hey, fresca could be lifesaving. It has EDTA in it, so maybe if you had lead poisoning and drank some it would save your life.
