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
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
A new study looked at a more realistic concentration level of tiny plastics like the kind we see in the ocean, and found the pieces quickly get lodged in animals’ tissue. Continue reading Billions of Ocean Nanoplastics Can Get Lodged in Sea Creatures in Only a Few Hours
A study published this week in ‘Environmental Science & Technology’ sampled salt brands from across the globe and found 92 percent contained microplastics. Continue reading You’re Literally Sprinkling Plastic On Your Food
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

Do you have a couple of minutes? Literally and precisely, two minutes. That’s how long these ten songs play. So what? A short song is not new, but these ten songs are part of a campaign to encourage residents of Cape Town, South Africa to cap their showers at one-hundred-twenty seconds. Some of us do not have to worry about droughts or water bills, but most of us are concerned about one or both of those, and this ingenious campaign alerted people to the problem, gave them the means to time themselves, and made it pleasant, not oppressive. The songs …read more
The island nation’s new warning system will broadcast qualitative alerts like takai and kyodai (“high” and “huge”) during future Pacific megathrust earthquakes, to better urge people to evacuate before the waves come. Continue reading Preparing for Japan’s Next Tsunami
Water rockets are one of the most fun and exciting science-adjacent activities one can take part in during the summer, and are popular with children and adults alike. Designs range from a bike pump with a cork in a bottle, up to significantly more advanced hardware. [Air.command]’s two-stage water rocket definitely fits into the latter category.
The build is initially somewhat confronting in its complexity, but after a thorough read-through the operating principles become clear. It’s an all-mechanical setup which relies on the weight of the upper stage and the initial acceleration of the rocket to keep the two stages …read more
Researchers at a university in Israel have found ways to turn smart irrigation systems into a botnet that could theoretically drain some of a city’s water reserves. But don’t panic. Continue reading Hackers Could Cause Havoc By Pwning Internet-Connected Irrigation Systems
The scientific community cannot always agree on how much water a person needs in a day, and since we are not Fremen, we should give it more thought than we do. For many people, remembering to take a sip now and then is all we need and the H2gO is built to remind [Angeliki Beyko] when to reach for the water bottle. A kitchen timer would probably get the job done, but we can assure you, that is not how we do things around here.
A cast silicone droplet lights up to show how much water you have drunk and …read more
