Yeah, maybe I was just wishing or positively thinking about the coffee pot idea, but if it doesn't work then yes, I may make a clamped lid with simple safety valve and cooling tube for my powerpot or another cooking pot.
I'm off to the tropics and if another tsunami or hurricane then I wanna have my drinking water solved if my water filter breaks or gets lost.
Something small for my daypack.
Cheers chaps.
As red says the amount of fuel needed to distill enough water to survive is ridiculous, it's not like distilled water is good for you if you are dehydrated either.
Distilling water removes many of the minerals like calcium, magnesium and iron, minerals that are exactly what you want when you are dehydrated.
Lack of drinking water will not be a problem during or shortly after a hurricane, as it will drop a fair amount of drinkable fresh water.
A Tsunami is a different matter, there should still be places on higher ground with fresh water though.
Just boiling this will render it safe in most circumstances (chemical pollution aside), something like one of the Sawyer 0.02 micron water filters will have it safe to drink (again chemical pollution aside), plus this filter has no moving parts so it tough to break.
Last resort in the tropics would be to buy some large clear bags.
Wrap said bags around tree branches and collect the water, usually has a few insects in as well, but that's just free protein.
One other possible solution after a tsunami would be to try and find a fairly new wrecked boat, most larger modern boats will have a ROI/desalination system onboard, might need a bit of bodging and borrowing of batteries etc but they'll likely be wrecked any ways.
Also worth checking around the emergency rafts as again most modern boats will have a emergency hand pumped ROI/desalination pump.
Not only will you get drinkable water from sea water with a hand pumped ROI pump, you'll also build shoulders and arm muscles Arny would be proud of.
