Voyage to the bottom of the sea: Gizmag test drives U-Boat Worx' C-Explorer 2 submarine

Unless you're a submarine pilot, it isn't every day you get to pilot a submarine, and so I'm in Malta to test drive U-Boat Worx' C-Explorer 2. The 2 isn't a version number, but denotes that this is a two-seater submarine. Coincidentally, it also denotes roughly the number of millions of euros you'd need to buy one. It's a millionaires' plaything designed for exploring under the sea to depths between 100 m (328 ft) and 1,000 m (3,280 ft), depending on the spec. My mission: to explore a wreck at the bottom of the Mediterranean Sea. Equipped with U-Boat Worx' GoPro video cameras in and outside the sub, my trusty point and shoot camera and a dictaphone smartphone app, I'm as ready as I'll ever be for my appointment at the seabed.

NASA discovers that the Moon is much wetter than we thought

Data from NASA's Moon Mineralogy Mapper (M3) aboard the Indian Chandrayaan-1 probe has shown that there is water locked in mineral grains on the surface on our satellite's surface. Scientists had previously thought that small amounts of moisture were being generated by solar wind and other factors, but the latest findings are strong evidence that the Moon contains large quantities of its own "magmatic water" from deep within its core.

New technique for turning sunshine and water into hydrogen fuel

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

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

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

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

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

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.
