Graphene-based sieve turns seawater into drinking water

Graphene The New Wonder Material

Graphene is one atom thick, it is carbon, relatively easy to make and raw carbon is everywhere. It can perform may functions, it is a conductor, formidably strong and it seems can be made to do almost anything.

One of the most useful things recently considered is to filter water. Though we already do that for large particles such as pollutants, pushbikes, shopping trolleys and dead bodies we are not so good at doing so for small particles, specifically salt.

No they can make a ‘sieve’ fine enough to allow water molecules through but not salt, desalination can now be much more cost effective hopefully. See this link http://www.bbc.co.uk/news/science-environment-39482342

Graphene Could Solve Many Problems

The arctic ice caps are melting, the deserts are expanding, people are starving and have limited access to clean water.

Those rising sea levels are threatening ancient coastlines and archipelagos are submerging. This could be countered in some way by increasing desalination plants to take that excess sea water and use it to provide much needed drinking water. This would help with irrigation for crops and boost food supply. If we can gain a foot hold on the deserts and make them fertile again perhaps even global warming could be reduced.

This is excellent news and could be a cure to many human ills.
