It produces enough fresh water for a single individual. Any waste
water could also be used of course.
The two vessels are stilled connected with manufactured tubing and
the top container need to be sealed to produce pressure. It would be
better to do something clever and cheaper than what is shown here.
Black enameled metal will also work well and producing an inverted
bowl for the bottom of the container will reduce the total volume and
generally allow more fluid to be in contact with hot metal. The
bottom container is not so nearly ctritical and could easily be any
standard basin basin and the cone a metal lid with a formed lid to
hold inside the basin's edge.
We have already established that the volume will be a gallon per day
so there is no reason to allow a volume greater than that in the top
device.
This is certainly a welcome idea.
Solar-powered oven
makes fresh water

Sometimes the simplest
ideas are the best. Concerned about the lack of fresh water in the
developing world, designer Gabriele Diamanti wanted a solution to
desalinate water that was available to households rather than relying
on giant, centralized plants. He also wanted it to be something
inexpensive that could be made by local craftsman. The result is a
ceramic solar still called the Eliodomestico that operates like an
“upside-down coffee percolator”.
The open-source design
of the Eliodomestico is remarkably simple. It consists of two ceramic
pieces that sit one atop the other. Inside the top piece is a black
container into which salt water is poured. The sun heats the
container, turning the water to steam. As pressure builds, the steam
is forced down a tube into a container in the lower piece. There it
condenses against the lid and collects in the basin of the container.
The Eliodomestico
collects about five liters (1.09 gal) of fresh water per day and
costs about US$50 to build with no operating costs. The bottom
container’s basin is designed to be transported on the head, which
is a common practice in developing countries.
The design was a
finalist at Prix Emile Hermès competition 201, received special
mention at the Well-Tech Award 2012 and was the pro winner of the
Core77 Design Awards 2012, social impact category.

Hi arclein,
I think it's really needed for our present environment.
