Thanks for all the replies and imput.
Perhaps I should clarify, I am interested in redundancies. For all possibilities. I have a domestic tap. The well delivers. Limited by law to 15 gpm. I have a regular high power pump, a solar pump down the hole, and one on the shelf. The well contains ferrous iron at 11ppm. It is clear. When exposed to air it oxidizes and precipitates. We have a 2000 gpd reverse osmosis system preceded by an air injection and twin self flushing catalyzer tanks but have never used it. It is a contingency plan. It uses consumables and electricity that I'd rather not. I understand that I could easily build or buy a still and run it on top of a wood stove or fire and get maybe a couple gph. That sounds like a little bit more chopping wood than I'm into.
We have all the energy we need. Fusion energy is free abundant and available to all for a portion of the day.
I'm more interested in people's experience with something similar to the previous examples shown, or inclined flat plate type systems, or possibly vacuum tube parabolic systems, even that's starting to get a little too techy an fiddly for my steez.
I dig the fresnel lenses, melting stuff with them is big fun, problem with those is the constant need to be re-oriented.
Chemical and radiological remediation is the goal.
I want to have the ability to produce as much distilled drinking water for as many family and neighbors when the need arises.
