Researchers at the Swiss Institute of Technology develop osmotic nanogenerators based on atom thick MoS sheets

Salinity differences (e.g. at river mouths where fresh water mixes with salty ocean water) are a potential source of energy, although no practical method of converting the chemical potential differences to electricity have ever been developed. Chemistry World recently published an article about the development of MoS2 osmotic nano generators which set record performance levels in this obscure branch of renewable energy generation. However, even though this electricity generation method may find niche applications, it appears that the costs will still be too high to allow it to become a significant contributor to the global supply of energy.
