— Good Thinking

The Drinkable Book has water-purifying pages

For people in developing nations or rural locations, getting clean water may soon be as simple as opening a book … and ripping a page out. That’s the idea behind The Drinkable Book, developed by Carnegie Mellon University postdoc Theresa Dankovich. Each of its pages is made from a thick sheet of paper impregnated with silver and copper nanoparticles, that kill 99.9 percent of microbes in tainted water that’s filtered through it.

Pura smart water fountain monitors your cat's drinking habits

Cats are finicky at the best of times, but when it comes to drinking enough water they really don't seem to know what's best for them. Chances are you don't either. But a Taiwanese startup called Noacare believes it can sort both parties out with a smart water fountain. This new fountain, Pura, syncs with a tag on your cat's collar and an app on your smartphone to keep you up to speed on your feline friend's water intake so that you can prevent health problems before they occur.

Engineers create a computer with a water droplet processor

From driving water wheels to turning turbines, water has been used as the prime mover of machinery and the powerhouse of industry for many centuries. In ancient times, the forces of flowing water were even harnessed to power the first rudimentary clocks. Now, engineers at Stanford University have created the world’s first water-operated computer. Using magnetized particles flowing through a micro-miniature network of channels, the machine runs like clockwork and is claimed to be capable of performing complex logical operations.

Rain Lamp makes a splash at home

A new light by designer Richard Clarkson puts two elements together that are ordinarily kept well apart. The Rain Lamp combines water and electricity, with light shone through a reservoir in the bottom of a large, clear, acrylic globe. The light creates "mesmerizing ripple patterns" on the floor or surface below.

New "4D-printing" material can change shape in hot water

Researchers at the University of Wollongong, Australia have created a 3D printer-compatible hydrogel that is mechanically tough and able to repeatedly change shape in response to water temperature. The scientists have demonstrated the technology by 3D-printing an autonomous water valve, but the material could also be used to create soft robots, custom designed sensors and self-assembling macrostructures.

ReFlow reuses grey water, saves fresh water

"Water, water, everywhere, nor any drop to drink." The famous line from the poem The Rime of the Ancient Mariner by Samuel Taylor Coleridge rings increasingly true, as all over the world water shortages threaten the way of life people have grown used to. Climate change and overpopulation have compromised water sources, a threat that calls for ingenious solutions to reduce demand. One of these is the ReFlow G2RSystem (or Re-Flow for short), a system that recycles grey water from the shower or bath to the toilet tank to flush waste. Read More

Inkjet printers could produce paper sensors that identify dangerous food and water contaminants

Sensors that identify infectious disease and food contaminants may soon be printed on paper using ordinary office inkjet printers. Researchers at McMaster University have developed a prototype that could lead to a commercial product in the next few years which helps doctors and scientists in the field quickly detect certain types of cancer or bacterial and respiratory infections or monitor toxin levels in water.
