Jolly Roger, nice with even more of what I think you call an idiomatic scentence.
That one I have heard before and I sure do understand that you wonder where this thread is leading or what to get out of it.
It might be due the fact that it started out as a question regarding if we can get our fresh water any other way than the traditional.
Of course you can go anywhere using tanks
and betting on your good fortune in finding fresh water or using a genset and watermaker
or anything in between.
Personally I´m a bit tired in the complexity involved with all this gear
even though I must admit it is nice fireing the genset up and producing water , cooling
and topping the batteries up.
The downside is servicing the genset and the watermaker
and having to go and fill the diesel
The post is really about if it is possible to find another sollution using the combined knowledge in a community like this.
I hope that finally there will be a conclusion to the original question.
If the awnser is yes - fine then lets try it out in real life , if the awnser is no then at least I do not have to try it just to find what you all could have told me in the first place!
I do have to take responsibility for not having produced anything of an easy to understand sketch.
Will try to do so after this weekend!
Perhaps you could call this idea a version of a hand and sun driven watermaker depending if you use an electric
or hand driven pump to initiate the vacuum.
I would say that you then do not have to worry about no working genset ,watermaker , diesel shortage or the financial worries of keeping these things running.
The brewing moonshine aspect I do not take as a thing to worry about , it might even be a possibillity........for those so inclined.
Hope your ocean crossing
is in a warm , nice and cosy place of the planet.
