In some parts of the world where there is a lack of freshwater, people can only get potable water by solar or heat, but a study by the University of Maryland is expected to bring them a simpler and more affordable water treatment solution. The key is to use the wood after burning as a material in the sunlight, the untreated water vapor through the surface of the material, concentrated in the form of purified water can be collected, while the salt and pollutants on the other side .

In terms of applied materials, scientists have had some success with graphite and copper recently, but a research team led by Professor Hu Liangbing at the University of Maryland came up with a similar effect with charred carbonized wood (absorbing sunlight from the upper surface Light and heat).
The effect is even better with porous woods such as poplar and pine, where water can be extracted from the lower layer to the surface and, once sunblown, can extract more moisture.

In laboratory tests, the researchers used a large slab of wood chips, and Professor Hu said the technology could easily be extended to water treatment plants to create a fairly efficient filtration unit.
This has also been demonstrated by recent research by the Massachusetts Institute of Technology (MIT) and the Royal Swedish Institute of Technology (RIT), and details of the study have been published in the recently published Joule Journal.
