SEADOG Uses Waves' Own Power to Desalinate Sea Water

A company called Renew Blue, Inc. will use wave power to run a desalination plant in Freeport, Texas. The resulted water will be finally put into corn-based biodegradable plastic bottles. The SEADOG power system is made from a buoy which puts in motion a piston mechanism that rotates a water wheel to generate electricity.

Freshwater and Electricity Through Osmosis

Robert McGinnis, Yale doctoral student and Menachem Elimelech, Chair of Chemical and Environmental Engineering, have developed systems that can harness the power of osmosis to transform non-potable water sources like seawater to freshwater and generate in the same time electricity.

Low Energy Water Desalination Through Nanotechnology

The Lawrence Livermore National Laboratory has found out a greener way to desalinize sea water. It uses carbon nanotubes which have pores that are 100,000 times smaller than a human hair, and were able to determine the rejection mechanism within the pores.
