Graphene Desalinates Sea Water

Even though the majority of the Earth is covered in water, a surprising number of people around the world don’t have easy access to clean drinking water. The oceans of course are full of salt, and it is difficult to filter that salt out. Researchers at the University of Manchester …read more

NASA’s Mars Opportunity Rover Is Likely Dead

Mission leads have not heard from Oppy since it was caught in a massive dust storm last June. On Wednesday, NASA will likely announce that it has died. Continue reading NASA’s Mars Opportunity Rover Is Likely Dead

Create an Aurora Of Your Own

Throughout our day-to-day experiences, we come across or make use of many scientific principles which we might not be aware of, even if we immediately recognize them when they’re described. One such curiosity is that of caustics, which refers not only to corrosive substances, but can also refer to a behavior of light that can be observed when it passes through transparent objects. Holding up a glass to a light source will produce the effect, for example, and while this is certainly interesting, there are also ways of manipulating these patterns using lasers, which makes an aurora-like effect.

The first …read more

Desalination Produces 50 Percent More Toxic Brine Than Previously Thought

The world’s desalination plants, which use energy intensive processes to remove salt from water, produce enough toxic brine each year to cover all of Florida under a foot of water. Continue reading Desalination Produces 50 Percent More Toxic Brine Than Previously Thought

Artistic Images Made With Water Lens

It’s said that beauty and art can be found anywhere, as long as you look for it. The latest art project from [dmitry] both looks in unassuming places for that beauty, and projects what it sees for everyone to view. Like most of his projects, it’s able to produce its artwork in a very unconventional way. This particular project uses water as a lens, and by heating and cooling the water it produces a changing image.

The art installation uses a Peltier cooler to periodically freeze the water that’s being used as a lens. When light is projected through the …read more

Continuous Seltzer Deployment System Solves Our Bubbly-Water Sourcing Problems

Seltzer water – that bubbly, carbonated water that disappoints sugar-craving children everywhere – has experienced a steady rise in popularity over the past few years. This is perhaps partly fueled by the availability of countertop carbonators such as the SodaStream.

Not satisfied with the tedious and pedestrian process of manually carbonating individual bottles of water, [piyoman] has instead built a tidy little tap of unlimited cold, filtered seltzer. It’s no easy gag. The build uses a commercial carbonator pump, reverse osmosis water filter, bulk tank, and a standard CO2 cylinder to create a constant source of carbonated water. Most of …read more
