Hand-operated emergency water pump for emergency kits, life raftsProduces 30 oz or 890ml of drinking water in 1 hourEnough for a life raft with up to 1-6 peopleWeighs 2.5 pounds
Reverse osmosis has no real debilitating effects, it's already in use to produce commercial drinking water, and it can easily be scaled down to devices with a pump that can filter more or less anything out of water, you can also use sugar to power it (if you put sugar on the dry side, the sugar will suck the water out of the salt water, giving you a drinkable solution with no energy input).
The issue with these devices are that you generally need very powerful pumps with large energy demands, because to get decent flow you need a high pressure, this graphene thing says they can reduce the power needed by the pump significantly (and then it goes onto claim that it wouldn't use energy, which is false, though it may be low enough to be a non-issue). Of course graphene is ridiculously expensive right now so it's not worth it (yet).

So much scepticism. Guys this concept does work, you can create this sort of pressure by hand an ounce of water every two minutes can be done with survival RO units.
Hand RO units have been on the go for a long time, Katadyn make them. Here's an example. http://www.amazon.com/Katadyn-8013418-Survivor-06-Desalinator/dp/B000F395X0
He had inflatable solar stills.
Of course nowadays they have a pump-able water desalinator

Not cheap!
That's pretty cool, a bit pricey and slower than I'd like (1.6 gal per hour of hand operation) but useful for sure.
I think any time you are looking for something that can deal with sea water, it's probably an emergency desalinator that is kept as standard equipment on life rafts and such. But unfortunately this type of pump desalinators are exceptionally expensive.
There are cheaper options using reverse osmosis kits but are still fairly expensive for the purpose of handling water (i.e. one time use kit), in addition to requiring quite some time for them to work.
