As the world's population continues to grow, fresh water is becoming one of the most valuable (and contested) resources on the planet. Whether it's for drinking, agriculture, or keeping our armpits clean, we need more of it, and we now may be able to make that happen with little more than a fancy battery.
Ask any superhero who isn't fortunate enough to have a built-in flying ability whether they prefer jetpacks or rocket boots, and they'll always say rocket boots.* Why? Because rocket boots let you do tricks. We might not have proper rocket boots yet, but these water-powered ones are the next best thing. And they're even affordable.
We've known about the effectiveness of ultrasonic cleaning for years, but it only really works on objects that fit in a special bathtub that can generate ultrasonic waves. A team of scientists from the University of Southampton have come up with a faucet attachment that gives any stream of water the same magical cleaning power.
Drinking the tap water in a place you're not familiar with can bring on some pretty nasty business, but carrying a Brita Pitcher around with you isn't really practical. But carrying around the SteriPEN is!
Never go thirsty ever again. Hyeona Yang and Joshua Noble's "Raincatch" raincoat isn't your everyday poncho. The "Raincatch" collects rain and then purifies it, allowing wearers to drink that delicious water from the heavens.
There's a lot of fresh water stored up at the poles. In fact, Antarctica by itself contains about 70% of the Earth's entire fresh water supply. So it's not too crazy to think about maybe chopping some of that off and shipping it to thirsty people in Africa, right? Or maybe it is crazy, but a new simulation shows that it might actually work.
One of the experiments heading into space when Atlantis launches at the end of the week is a magical bag that can turn any kind of liquid (any kind of liquid) into a tasty electrolyte-filled sports drink without needing any energy input at all.
Firefighters have been dousing flames with water for centuries. Sure the water delivery tech has improved a lot, but the basic approach of dumping water on the flames goes back to Roman times. Now a group of scientists from Harvard is proposing a way to extinguish flames using high powered jolts of electricity.
Most people don't want to hurt innocent animals, so this sink appeals to your sense of humanity to make you save water. As the water flows the level in the fish tank drops. Use too much, and the poor little fish will soon be flopping around in an empty tank.
A drop of water might look perfectly clean to the naked eye, but get up close and you'll probably find lots of creep crawlies. All you need is a laser lit microscope to see it.
