Desalination

Some types of water are too salty for current desalination systems to handle. Scientists have now developed a potential solution to this problem, with a solar-powered desalination system that resists corrosion thanks to a special coating.

Whether they're travellers or people living in developing nations, many folks may find themselves near the ocean and in need of drinking water. That's where the QuenchSea is made to come in, as it's a portable, relatively cheap desalination device.

Seawater is a complex cocktail of useful minerals, but it’s hard to separate the ones we need. Now a team of scientists from Australia and the US has developed a new water desalination technique that can not only make seawater fresh enough to drink, but recover lithium ions for use in batteries.

Thorium reactors have long been proposed as a cleaner, safer alternative to nuclear energy. Now Russian scientists propose a new thorium reactor design that can burn weapons-grade plutonium, producing power and thermal energy while disposing of nuclear waste at the same time.

Researchers at the University of Illinois have come up with a new battery design that not only relies on salt water to store and release electricity, but removes the salt ions from the water in the process.

​Engineers have used nanotechnology to model a new membrane that can filter salt from seawater at higher volumes than ever before. The membrane, made from molybdenum disulfide, “pulls” clean molecules water through itself. Potentially, this could make desalination plants much more energy-efficient.

Pipes made from a polymer-copper blend could make the desalination of seawater considerably less expensive.

MIT researchers have developed a portable, solar-powered water desalination system that could provide water in disaster zones and remote regions around the globe.

The Sea Kettle concept life raft not only aims to provide shelter from the elements but also drinking water from the sea
