Stop and listen while I elaborate on NASA's latest discovery: Mercury might have water ice hidden in craters up around its north pole. No fakin'.
Polaris is the latest robotic rover getting ready to roll. Before you say "meh," given that Curiosity is tearing around Mars, Polaris will be doing something just as worth: hunting for minerals on the moon. What's more, it will be doing it the harshest conditions possible the moon's north pole.
Thirsty? No? You will be. It's just a matter of time. It's also just a matter of time until the expansion of humanity makes fresh water a more precious commodity than a new iPhone, but graphene sheets with lots of little holes in them could soon solve the problem by making fresh water from salt water with incredible efficiency.
First came the water-powered jetpack. Next came the water-powered jetboots. And now, we have the water-powered jetbike. It's Jetaviation's Jetovator, and they want you to "turn off the video games Saddle up and Ride the Hose!" So, go on, ride the hose. Ride it. RIDE IT.
Even the latest picture from space showing a gloriously colorful Earth hasn't changed the view that we are largely covered in water. Well, this new depiction takes all of the Earth's water and gives it some scale as a 3D visualization in comparison with our planet. The result is pretty surprising.
Anyone can sit in an inflatable pool chair pretending that they're somehow lighter than the water, but this ultra-buoyant mat will let you walk around as you float along on the surface.
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!
