I'm not seeking a pissing match, I'm merely pointing out the notable differences between the two concepts in the context in which I set the topic.  The thread is also months old and your coming into at at a very late stage promoting a device that by your own admission is unlikely to be adopted...

One; the device is made from platinum silicone rubber, so cannot be "destroyed" unless it is left to be kicked around the floor of the boat, which is no different from any other device you'd purchase: Abuse it and it will not perform; Leave it in an insecure place and it will not be there when...

Compare that to a device that is the same packed shape/size/weight as an A4 padded envelope. AND that can perform a secondary function of being a over-fire cooking pot.

It looks excellent, Scott.  but it is bulky, and I'd imagine it'll cost a hell of a lot more than the $40 USD my own design would cost (max). This is the point of my design, to get subsistence water purification as compact and low-cost as possible to make the product feasible for military...

Just a quick update to clarify things re the Katadyn filters mentioned earlier... Not all Katadyn filter systems will desalinate seawater, in fact, very few will and some are available by special order only.  The cheaper off-the shelf filter systems do not desalinate. The desalination Katadyn...

I had considered that Colin, however I'd like to be able to mold several prototypes from the same mold, because I'll be testing each one to destruction!  I reckon it'll work out cheaper to get one mold made rather than get just one prototype printed.  But I appreciate the suggestion. :subbies:

LOL... yeah, the very thought of it is kinda comical! But no, there's no need for a huge surface area like that.  :D The external surface of the device can be finely textured, which will more than triple the air-cooled surface area than if it were completely smooth. The device doesn't need to...

No MCG, go back to the main description posted Saturday and read.

Re: "The big reveal". The mold I require to make the first working prototype is in a queue at a local machine shop.  I hope to have it by the end of January.  Then I can hand-mold the first true-to-manufactured-form models and put them through some tests.  The whole purpose of this particular...

As it happens Scott, I've carried these replacement filters and a short length of tubing as part of a survival kit for years- great for most fresh water applications out in the bush.  But it was after spending time ocean sailing that I asked myself what the available equipment was for those...

Good point, Urocyon! Yes, fine filter systems break down quickly in cold conditions.  That said, you tend to find less pathogens in ground water in colder climes.  But certainly, it should be borne in mind.  Hopefully, most survivors of incidents in colder climates put fire and shelter first...

Thanks guys, Much obliged MCG, I'll look into that later! Yeah Bearpaw, I feel our military quartermasters might like the concept I've proposed over filtration units, especially given that it's so light, needs no replacement elements and should be considerably cheaper than the other options. ...

That unit will not desalinate seawater, Bearpaw.  Nor will it or the Catadyn filter extract fresh water from soil or plant flesh.

Good morning all, As promised, i'm back to explain my patent-pending water purification survival device. To help readers understand how it resolves the issues with the prior art, I'll explain how I came up with it... At the moment, there are only two devices available to the market that will...

Guys, I'm very impressed with your thoughtful enquiries and insight.  Thanks again for all your feedback, I'll come back in tomorrow to explain things more fully. Blackadder, I hope you'll be back soon to read my detailed description. Eye in the Sky, yes, thus far I've had exactly the feedback...

Hi Bearpaw,  you're quite correct, your bottle will only kill bacteria... and depends entirely upon the availability of strong sunlight. The device I have designed will desalinate and remove harmful chemicals and bacteria (without filtration). Lifestraw is a good product Colin, but it is a...

It depends on how you use it i.e.- the specific circumstances you have found yourself in. If there is no standing water and no additional heat source except body heat, it will supply only a subsistence level of clean fresh water.  Sufficient only to keep you alive, extracted from whatever damp...

That's effectively what my device promises to deliver, Eye in the Sky... a device you can leave on the ground, wear on your person or attach to vegetation. It will allow you to passively purify a subsistence level of water for extreme survival emergencies, or larger amounts for longer-term...

I am testing feedback for the conceptual qualities of my device to see just how interested those who are mindful of such requirements might be, should I pour more cash into development at this early stage.  I am not exactly "well off" at the moment, so must choose where to put my money and weigh...

And you carry that 15 gallons on your back?
