A team in Australia has used floating light-absorbing materials to build an improved solar device for desalination.
The materials consist of Fe3O4/C particles and can be used as an alternative to black plastic bubble sheets that are placed at the bottom of solar ponds to increase sunlight absorption. Existing bubble sheets increase evaporation by 10%, but these new materials increase evaporation by 230%.
