GXV-T aims to make tanks half as heavy and twice as fast (Image: DARPA)

As a quick visit to any armored division will make obvious, tanks are big ... really big. A Challenger 2 main battle tank, for example, weighs 62.5 tonnes (68.9 tons) and costs about £4.2 million (US$7 million). And as anti-tank weapons get better, tanks can only get bigger. To avoid armies of tomorrow having to pay for land-going battleships, DARPA’s Ground X-Vehicle Technology (GXV-T) program aims at developing lighter, more agile successors to the tank that protect themselves with more than ever-thicker walls of steel.  Read More

In a new study that may greatly add to our understanding of the drivers behind climate change, researchers from Lund University in Sweden claim to have accurately reconstructed solar activity levels during the last ice age. By analyzing trace elements in ice core samples in Greenland and cave mineral formations in China, the scientists assert that regional climate is more influenced by the sun than previously thought.  Read More

The Nomad hot tub, by Portland, Oregon-based company The Original Nomad

When planning a camping trip, most people tend to pack stuff like matches, coffee, and a spare pack of batteries. Thanks to The Original Nomad, you're now able to add a hot tub to the list, as the firm has just launched a collapsible tub geared towards campers.  Read More

The Transustainable House, by Japanese architecture firm Sugawaradaisuke (Photo: Jérémie S...

Japanese homes are often designed to last a relatively short time before being demolished and rebuilt, so it's little wonder that the country produces a disproportionately high number of quirky residences. The Transustainable House reflects this trend, and sports a facade that rusts over time. In addition, despite measuring just 38 sq m (409 sq ft), it can house up to three groups of people at once.  Read More

The ButterUp butter knife has a built-in grater to make cold butter easier to spread

Many a sandwich has been ruined by overzealous buttering with fridge-cold butter. The anguish of torn bread may now be a thing of the past, though, thanks to a newly-designed butter knife. The ButterUp knife has a built-in grater to soften butter for spreading.  Read More

The AirEnergy3D Project is an open source, 3D printed, portable wind turbine prototype

The AirEnergy3D is an open source, 3D-printed, portable wind turbine prototype whose creators claim will be able to generate up to 300 W of power. Designed to be easily assembled and disassembled without tools, the device is intended to be compact enough to be transported in a backpack, allowing it to be taken camping or anywhere else that there is a breeze and no access to the electricity grid.  Read More

The Queen B (Bioshielding) model, by Noah Hornberger won a competition hosted by NASA and ...

If humans successfully colonize Mars in the future, what kind of homes will they inhabit? NASA and MakerBot recently hosted a competition which tasked people with making a 3D-printed model home suitable for the Red Planet. Noah Hornberger won with his Queen B (Bioshielding) concept home, which offers food-for-thought concerning the future of interplanetary architecture.  Read More

The FourSixteen is claimed faster through initial acceleration than a Model S thanks to a ...

On the road and stylistically, the Tesla Model S is simply outstanding. But If you’re Saleen Automotive founder and performance mod-guru Steve Saleen, you see room for improvement. I spoke to him on the concept lawn at Pebble Beach's Concours d’Elegance about his vision of a better Tesla, which is realized in the FourSixteen.  Read More

From left to right: the second prototype Hoverbike, the drone (in flight), and the origina...

Last month we covered the launch of an interesting Kickstarter project that aimed to jump-start sales of a drone version of a fully-functional hover bike. The quadcopter drone acts as a proof of concept for the full-sized manned vehicle, with proceeds from the crowdfunding effort intended to fuel the continued development of the final vehicle. Gizmag visited the Malloy Aeronautics workshop in the UK to take a closer look at the Hoverbike project.  Read More

The Naturbad Riehen swimming pool is entirely chemical-free (Photo: Helen Schneider)

A whiff of chlorine is virtually synonymous with taking a dip in a swimming pool. While it helps to kill off bacteria, it also serves as a subtle reminder that you are wading around in chemically treated water (if tasting the odd mouthful just isn't enough). Switzerland's Naturbad Riehen swimming pool is entirely chemical-free, relying instead on a biological filter system to provide clean and natural water for thousands of patrons, no itchy red eyes in sight.  Read More
