Bushwalk Australia

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.

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

and thought that maybe this :

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...
Franco

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.
