Is there a light weight still available on the market for processing salt water to fresh? I know a few sea kayakers that are working on them and can produce 1.5 liters of fresh water in 50 minutes (on a wood fire) but was wondering if it has been done comercially in a lightweigh package (sea kayak models are a useable 860 grams). I know the Southern Islanders have no need for such things but us coastal mainlanders struggle to find water in some locations and such a machine would greatly ease the burden of water finding on many walks.

TIP: The online Bushwalk Inventory System can help bushwalkers with a variety of bushwalk planning tasks, including: Manage which items they take bushwalking so that they do not forget anything they might need, plan meals for their walks, and automatically compile food/fuel shopping lists (lists of consumables) required to make and cook the meals for each walk. It is particularly useful for planning for groups who share food or other items, but is also useful for individual walkers.

had a l,ook at that DIY bit you alluded to :

and thought that maybe this :
http://www.theboilerwerks.com/about/
type of burner (modified as above) would work well for that.
This particular is very small , but light, but a 1.5/2 L version could do.
In essence a lighter version of the Kelly Kettle or the NZ Thermette.

I just bought one of those pint size kettles...

I know nothing about them but this looked interesting:
KATADYN SURVIVOR 06 MANUAL DESALINATOR
Fact Sheet
According to the blurb "The world's smallest desalinator".
Weighs 1.13kg/Dimensions: 12.7 x 20.3 x 6.4 cm, so not too heavy/bulky for walking I guess.
Price looks to be about $A1600 though

890 ml per hour. That is a lot of pumping...

you can do it with a trangia-type stove kettle and some food grade tubing from the home brew shop... ok for smaller amounts... i have also used a roll of aluminium can wall to join the tube to the spout and to stop the tube getting hot enough to melt h ave messed around trying to use a s2s sink to help cool the tube too...

True Franco, but think of how fit you'd get....and probably thirsty
."Waste water provides pressure for easy pumping"
"Recirculation of energy reduces energy expended by 50-90%"
Maybe it's not too difficult? Although I don't think I'd enjoy standing around pumping for an hour to get <1 litre of water.

Steve - Andrew McAuley used a Kataydn 'Survivor-35' manual desalinator (15mins=1L) when he attempted the Tasman, according to Vicky McAuley's recent book 'Solo'. I just checked - it'd be heavier than your boat ! at 3.5kgs.
Nice story on the Nadgee Kayaks site.
