Faster, more efficient desalination process using carbon nanotubes developed

When it comes to desalinating salt water, two of the main options are thermal distillation and reverse osmosis. Thermal distillation involves boiling the water and collecting the resulting freshwater condensation, while reverse osmosis involves pressurizing the salt water and forcing it through a semipermeable membrane, which will allow water molecules to pass through, but not salt. Both of these methods, however, require a considerable amount of energy – not as environmentally sound as they could be, nor entirely practical for use in developing nations, where electricity isn’t readily available. Now, however, a newly-developed membrane that incorporates carbon nanotubes could make desalination much quicker, easier and energy-efficient.
