Salinity

Low-salt food without a flavor penalty could soon be on the menu. Japanese food and beverage giant Kirin has partnered with Meiji University researchers to demonstrate a set of electric chopsticks that can boost people's perception of saltiness.

"Hypersaline brine" is industrial waste-water with salt levels that exceed even that of seawater. It’s a big, expensive, destructive problem which a team of engineers at Columbia University in New York City hope to solve with their solvent-based method of desalination.

Waste water from the fracking is over five times saltier than seawater, which is not good. A research team led by MIT that has found an economical way of removing salt from fracking waste water that promises to not only reduce pollution, but conserve water as well.

Scientists at NASA say that Jupiter’s largest moon, Ganymede, may not have a single large ocean. Instead, it may be built like a club sandwich, with alternating layers of ice and water.

Researchers have created an experimental device that indicates boron nitride nanotubes provide an extremely efficient solution for converting the energy of salinity gradients into immediately usable electrical power.

The SMOS is the first ever satellite designed both to map sea surface salinity and to monitor soil moisture on a global scale and the unique radiometer it carries will play a key role in the monitoring of climate change on a global scale.

Using a modified microbial fuel cell, an international team of researchers has proven a process that cleans wastewater can also remove 90 percent of salt from brackish water or seawater while generating electricity.

As soil salinity threatens world food crops, a research team has found a way to make plants more salt tolerant.

The mini-mobile-modular (M3) “smart” water desalination and filtration system could help determine the feasibility of using available water as a source for a large-scale desalination plant.

Green energy comes in many guises these days, from wind-power to wave-power. One of the more compelling of the new kids on the eco-energy block is salinity power, which uses the concurrence of salt-water and freshwater in estuaries and marries it with the natural, effortless process of osmosis.
