New technique for turning sunshine and water into hydrogen fuel

By - August 5, 2013 3 Pictures
A new technique developed by a University of Colorado Boulder team converts sunshine and water directly into usable fuel. The technique involves concentrating sunlight in a solar tower to achieve temperatures high enough to drive chemical reactions that split water into its constituent oxygen and hydrogen molecules. In this way, the team says it should be able to cheaply produce massive amounts of hydrogen fuel. Read More

AquaTop Display brings immersive entertainment to your bathroom

By - August 2, 2013 3 Pictures
If you keep getting your gadgets wet because you can’t part with them while taking a bath, maybe it’s time for you to reevaluate your options. As it turns out, it only takes a Kinect camera, a projector, some waterproofed speakers, half a year of coding and an enormous amount of ingenuity to turn a regular bath into an interactive entertainment hub. And that’s exactly what a group of researchers from Koike Laboratory at Tokyo’s University of Electro-Communications have done as part of their quest to explore the field of natural user interface design. Their AquaTop Display takes immersive entertainment to a whole new level, unattainable with regular, impenetrable touch displays. Read More

Viteo Shower turns outdoor showering upside-down

By - July 31, 2013 7 Pictures
As someone who lives in the UK and can therefore count the number of hot days a year on one hand, the idea of having a permanent outdoor shower is rather novel. However, in countries where scorching summers are par for the course they're a common sight, but require plumbing and a dedicated space. The Viteo Shower avoids both these problems by literally turning the outdoor shower design on its head. Read More

WaterBean purifies tap water to reduce plastic bottle waste

By - July 28, 2013 3 Pictures
It's a given that recycling waste products is a good thing. It's certainly better than sending our trash to landfill where it will sit rotting (or not, in the case of non-biodegradable waste) for decades to come. However, even better than recycling is to not create the waste in the first place. Bottled water is now big business, and more popular than ever before, but bottled water guzzles energy and creates waste that really doesn't need to be created. WaterBean offers one possible solution to the problem. Read More

Sweat Machine turns perspiration into drinking water

By - July 22, 2013 4 Pictures
Unicef called upon the services of engineer Andreas Hammar to build the provocatively-named Sweat Machine which purifies sweat into drinking water. Though not intended as a serious measure to tackle shortages in drinking water, Unicef does hope to raise awareness of the issue, and invited visitors and footballers at last week's Gothia Cup soccer tournament to partake of a glass.

WaterBee puts crop irrigation on a smartphone

By - July 16, 2013 3 Pictures
With robots doing everything from milking cows to crop dusting, farming has come a long way since they days of plodding along behind a horse and plow. Irrigation practices are also benefiting from advances in technology. The large-scale WaterBee smart irrigation and water management system is a case in point: it allows farmers use their smartphones to not only switch on the water where and when it’s needed, but also to get up to the minute information on field conditions.

FLOW-AID helps farmers save water without sacrificing yields

By - July 11, 2013
We’ve already seen gadgets such as Koubachi and Flower Power, that communicate with users’ smartphones to let them know when their houseplants need watering. Scale that idea up to an agricultural level, and you get a prototype device known as the Farm Level Optimal Water management Assistant for Irrigation under Deficit – or FLOW-AID. It’s designed to let farmers in drought-stricken regions know when and how much water to apply to their crops, so they don’t run their irrigation systems unnecessarily. Read More

Scientists developing a seawater-desalination chip

By - July 4, 2013 2 Pictures
Although various alternative technologies are being developed, the large-scale desalination of seawater typically involves forcing it through a membrane that allows the water to pass through, but that traps the salt. These membranes can be costly, they can get fouled, and powerful pumps are required to push the water through. Now, however, scientists from the University of Texas at Austin and Germany’s University of Marburg are taking another approach. They’ve developed a chip that separates salt from water. Read More

Portable device detects toxic blue-green algae in water

Cyanobacteria, more commonly known as blue-green algae, can potentially be quite nasty. Some types of the bacteria produce toxins, which can poison humans or other animals that ingest water in which they’re present. Now, however, scientists are developing a portable sensor that will instantly alert users to the presence of the microbes in water samples. Read More

Scientists propose using gravity microlensing to keep Kepler in the hunt

By - June 19, 2013 5 Pictures
Last month, NASA declared its Kepler mission to hunt exoplanets at an end when one of the space telescope’s reaction wheels failed. Unable to keep itself pointed in the right direction, it could no longer carry on its hunt for planets beyond the Solar System. That seemed like the end of things, but Keith Horne of the University of St Andrews and Andrew Gould of Ohio State University disagree. They claim that Kepler could still hunt for exoplanets using gravity microlensing to detect how stars with planets distort space. Read More
