Proponents of clean energy will soon have a new source to add to their existing array of solar, wind, and hydropower: osmotic power. Or more specifically, energy generated by a natural phenomenon occurring when fresh water comes into contact with seawater through a membrane.
Researchers at EPFL's Laboratory of Nanoscale Biology have developed an osmotic power generation system that delivers never-before-seen yields. Their innovation lies in a three atoms thick membrane used to separate the two fluids. The results of their research have been published in Nature.

Part of the significance of these primary landscape components is understanding how water moves in relationship to land shape [topography]. Water is the basis of all life on earth, and the limiting factor in most agricultural production. Managing water effectively is crucial for future-proof resilient food systems.
What you notice if you get a map out is that the valleys are a small percentage of any landscape, while ridges make up the majority of the landscape. In Yeoman’s work, He observed how valleys tend to have adequate water and that ridges tend to dry out, rendering them unproductive.
