TU Delft's ambulance drone drastically increases chances of survival of cardiac arrest patients

12.12.2014 |

Graduate student Alec Momont of TU Delft has designed an unmanned, autonomously navigating mini aeroplane that can quickly deliver a defibrillator to where it is needed. A network of such drones could significantly increase the chance of survival following a cardiac arrest: from 8% to 80%! Alec Momont of TU Delft's Faculty of Industrial Design Engineering designed his prototype for an ambulance drone together with the Living Tomorrow innovation platform as part of his graduation programme.…

Shooting at the speed of light

09.12.2014 |

For most of us, high-speed image capture, say 120 or 240 frames per second, is enough to get a good look at stuff happening in the blink of an eye -- like a water droplet hitting the ground or a Bichon Frisé snagging his favorite ball. For faster subjects, industrial-strength high-speed cameras can grab tens of thousands of frames per second (or more). But when your rapidly moving target is light itself, you're going to need something a bit quicker -- to the tune of 100 billion fps, according…

Physicists achieve superconductivity at room temperature

07.12.2014 |

Physicists from the Max Planck Institute for the Structure and Dynamics of Matter have kept a piece of ceramic in a superconducting state, disproving the widely-held assumption that materials need to be cooled to temperatures of at least -140 degrees Celsius to achieve superconductivity. Publishing the results in the journal Nature, the team hopes the discovery will help drive the potential of superconductor technology in the future. “It could assist materials scientists to develop new…

Self-driving cars will ride in the UK

04.12.2014 |

We knew the U.K. government had given the go ahead to start testing driverless cars on British public roads from this January — backed by £10 million of taxpayer money — but we didn’t exactly know where and by whom. My hope was that Milton Keynes would be chosen, simply because it is a town almost entirely made up of roundabouts. And, indeed, Milton Keynes does make this list. Today, Innovate UK, the government quango charged with overseeing the country’s driverless plans, announced that our…

Solar bike lanes from Netherlands

03.12.2014 |

It's tough to make cycling any greener, but the Dutch have done just that with a bike lane that powers street lights and even houses. What's being billed as the world's first solar-powered bike path will officially open on November 12 in Krommenie, a town northwest of Amsterdam. Riders will be able to hop on at one end and then, after a few seconds of pedaling, dismount at the other. Being a pilot project, the lane is only 230 feet long (though it'll stretch to 328 feet when finished). …

Li-Fi is evolving

02.12.2014 |

As LEDs become a more common source for room lighting, they’re opening a new pathway for linking mobile devices to the Internet, with the potential for wider bandwidth and quicker response time than Wi-Fi. At least that’s what researchers such as Harald Haas, chair of mobile communications at the University of Edinburgh, are hoping. “All the components, all the mechanisms exist already,” Haas says. “You just have to put them together and make them work.” Haas’s group, along with…

Self-flying helicopter for fighting wildfires

23.11.2014 |

Fighting a wildfire requires a lot of manpower and a lot of equipment, including helicopters and airplanes for aerial support. The problem with the humans in those aircraft, however, is not only that do they put their lives at risk—and sometimes lose them—they’re not actually very efficient. Pilots need to do things like eat, use the bathroom, and sleep. That means spotter planes and water bombing helicopters spend more time on the tarmac than they do actually fighting fires. That’s why…

Glowing highways from Netherlands

23.11.2014 |

In a small town about 60 miles southwest of Amsterdam lies a stretch of road with no streetlights. Instead, along some 15,000 feet of Highway N329, cars follow stripes of glowing green paint that illuminate the edges of the road like an airfield landing strip at night. Designer Daan Roosegaarde calls it the highway of the future. For the past several years, Roosegaarde and his team of Dutch designers have been working on making these glowing lines a reality. This road in the Netherlands is the…

Impossible - the bike that fits in your backpack

21.11.2014 |

Finally the goal of electric bike manufacturers everywhere has been achieved in the aptly named Impossible. This electric bike folds down so small it'll fit in your backpack with room to spare. Impossible, which deserves to win all the design awards, is a good looking bike that ingeniously folds down into a case that doubles as the saddle. It's currently on Kickstarter smashing its goal which is well deserved after three years in the planning. Despite its size the Impossible bike is able to…
