How do you make pure drinking water using only a piece of aluminum?

they took a simple piece of cheapo aluminum, and with some quick laser etching turned it into a super-wicking, super-light-absorbing, super-water-evaporating surface that provides easy water purification, using only light from the Sun.  I mean, they hit the trifecta.

Wow this is really cool!

Hey LTAM,

It appears graphene and graphene oxides can do this too with bacterial infused water:

How to purify water with graphene

Scientists from the National University of Science and Technology and colleagues from Derzhavin Tambov State University and Saratov Chernyshevsky State University have figured out that graphene is capable of purifying water, making it drinkable, without further chlorination. Captured bacterial cells form flakes that can be easily extracted from the water. Graphene separated by ultrasound can be reused. The article on the research is published in Materials Science & Engineering C.

Graphene and graphene oxide (a more stable version of the material in colloidal solutions) are carbon nanostructures that are extremely promising for biomedicine. For example, it can be used for targeted drug delivery on graphene scales and for tumor imaging. Another interesting property of graphene and graphene oxide is the ability to destroy bacterial cells, even without the additional use of antibiotic drugs.

In the current study, the researchers injected graphene oxide into solutions (nutrient medium and the saline) containing E.coli. Under the terms of the experiment, saline simulated water, and the nutrient medium simulated human body medium. The results showed that the graphene oxide along with the living and the destroyed bacteria form flakes inside the solutions. The resulting mass can be easily extracted, making water almost completely free of bacteria. If the extracted mass is then treated with ultrasound, graphene can be separated and reused.

It’s good to see that alternative water purification technologies exist.

1. Etched Aluminum surface. Clean water evaporates off the etched surface while leaving the contaminates behind - which will need to be washed off.

2. Graphene oxide. Tiny flakes of graphene can be added to water resulting in the formation of easily extractable masses of living and dead bacteria. The graphene oxide must be recovered as with ultrasound.

Quote. While it is not yet known exactly how the further destruction of bacteria occurs, researchers believe that graphene oxide provokes the formation of free radicals that are harmful to bacteria.

Here’s my obligatory charge field 2 cents. Graphene’s hexagonal array of carbon atoms channels charge more efficiently than water, causing a net water and ion flow toward the graphene. The graphene recycles larger volumes of charge photons while at the same forming an almost impenetrable barrier to gasses, larger atoms and molecules which join as charge bound masses. The higher volume of charge recycling through the graphene can ionize radicalize ( separate H20 into H + OH) water – too much energy for almost all bacteria to live with.

P.S. Change from ionize water to radicalize water.
