3D-printed tools from the ISS are back on Earth for testing

23.02.2015 |

We'll soon know if those wrenches the ISS astronauts 3D printed aboard the station are up to par. SpaceX's Dragon has brought the tools back to Earth, along with an assortment of experiment data and samples, on its way home from a resupply mission on February 10th. That means scientists will now be able to assess the wrenches and see if they're comparable to the real thing -- if they do, well, they're one step closer to approving 3D printers for future Mars manned missions. "For the printer's…

TUM researchers demonstrate: Brain controlled flight is possible

20.02.2015 |

Pilots of the future could be able to control their aircraft by merely thinking commands. Scientists of the Technische Universität München and the TU Berlin have now demonstrated the feasibility of flying via brain control – with astonishing accuracy. The pilot is wearing a white cap with myriad attached cables. His gaze is concentrated on the runway ahead of him. All of a sudden the control stick starts to move, as if by magic. The airplane banks and then approaches straight on towards the…

Fukushima decommissioning made 'significant progress': IAEA

18.02.2015 |

Japan has made "significant progress" in cleaning up the crippled Fukushima nuclear plant, a UN review mission said Tuesday as it again advised the country to consider discharging treated water into the sea. "Japan has made significant progress since our previous missions" in 2013, said Juan Carlos Lentijo, who led a review mission from the International Atomic Energy Agency. "The situation on the site has improved—progressive clean-up has led to reduced radiation levels in many parts of…

Europe's Reusable Spaceplane Completes First Test Flight

16.02.2015 |

A splashdown in the Pacific Ocean concluded the first successful test flight of Europe’s reusable spacecraft technology yesterday. The car-size Intermediate eXperimental Vehicle (IXV) could pave the way for a full-size reusable spaceplane. This would launch on Europe’s Vega rocket and eventually return to Earth by landing like an aircraft on a runway. The now-retired U.S. space shuttle fleet marked the world’s first concerted attempt to create reusable spacecraft technology, which should…

More wind power coming to Polish grid

13.02.2015 |

German energy company RWE said Monday the Polish renewable energy sector is a core market, with 73 megawatts of new wind power expected on the grid this year. The German company said construction work started Monday for the 14 wind tower systems of an installation called Nowy Staw near the Polish city of Gdansk. Once completed by the end of the year, the wind farm will have an installed capacity of 73 MW. "At the end of the year, one of the largest wind farms in Poland will produce green…

Rescue drone that can search buildings wins $1 million prize

11.02.2015 |

A clever, bizarre-looking drone that may one day save your butt has won a million bucks in the UAE's Drones for Good competition. Flyability's GimBall has the unusual ability to squeeze into tight indoor spaces and search for potential disaster victims, thanks to its geodesic design. The entire UAV is effectively a two-prop, electronically stabilized gimball surrounded by a tough, lightweight carbon fiber cage. Instead of trying to pull off the daunting task of avoiding obstacles, the GimBall…

Floating wind turbines bring electricity where it's needed

09.02.2015 |

It's a balloon that lifts a wind turbine. That's the easiest way to describe the technology being developed by Altaeros Energies, led by Ben Glass, inventor and CEO of the young company. Glass has reimagined the possibilities of balloon and airship technology to lift a wind turbine Most wind turbine manufacturers are competing to build taller turbines to harness more powerful winds above 500 feet, or 150 meters. Altaeros is going much higher with their novel Buoyant Airborne Turbine—the BAT.…

Swedish Company Inserts RFID Chips into Workers

06.02.2015 |

“We want to be able to understand this technology before big corporates and big government come to us and say everyone should get chipped – the tax authority chip, the Google or Facebook chip.” These are the words of Hannes Sjoblad who believes he is preparing us for the day when the government wants everyone to be chipped. He believes that starting a voluntary program now will allow much greater knowledge later, when we have little choice about it. Want to gain entry to your office, get on a…

Petrol-electric hybrid aircraft is first to charge in flight

04.02.2015 |

A hybrid power aircraft has been successfully tested in the UK in an important step towards cleaner low-carbon air travel. The aircraft, developed by researchers from Cambridge University with funding support from Boeing, is powered by a parallel hybrid-electric propulsion system where an electric motor and petrol engine work together to drive the propeller. It uses up to 30 per cent less fuel than a comparable plane with a petrol-only engine, and is also able to recharge its batteries in…

Germany's Autobahns Say "Willkommen" To Robocars

02.02.2015 |

It must be unnerving for a new driver to prepare to enter the passing lane only to see, at the last possible moment, a metallic monster streaking by. How much more nerve-wracking would it be if the monster had no driver at the wheel? For some, that would be the true test of robocar reliability. And, if Germany’s government has its way, it’ll happen first on that country’s autobahn system, famous for its speed-limit-free stretches. In an announcement earlier this week, the government said that…

Running fuel cells on bacteria

31.01.2015 |

Researchers in Norway have succeeded in getting bacteria to power a fuel cell. The "fuel" used is wastewater, and the products of the process are purified water droplets and electricity.The biological fuel cell is powered by entirely natural processes – with the help of living microorganisms. "In simple terms, this type of fuel cell works because the bacteria consume the waste materials found in the water", explains SINTEF researcher Luis Cesar Colmenares, who is running the project together…

The Bluewire Is A Bluetooth Headset That Can Record Your Calls

30.01.2015 |

Journalists, PR folk, and anyone else who needs to keep accurate copies of calls over the phone or Skype should check out the Bluewire, a new Bluetooth headet that just launched on Indiegogo. While there are plenty of headsets out there that give you a comfortable fit or decent sound quality compared to the earbuds that come with our phones, the Bluewire actually records conversations to a pre-installed MicroSD card – 1,000 hours of conversations, to be more precise. You don’t even have to…

It’s Too Soon to Judge Shale Gas

28.01.2015 |

Shale gas—that is, natural gas from shale deposits—may seem at first glance a huge, indisputable success for the United States. In 2007 it accounted for just 8 percent of the gas extracted; by 2013 its share had risen to nearly 40 percent. As a result, in 2009 the United States became the world’s largest producer of this, the cleanest of all fossil fuels. This surge has led to two far-reaching decouplings of price: between those of natural gas and crude oil, and between those of natural gas in…

These shoes generate power with every step you take

20.01.2015 |

Smartphones and wearable computers have become incredibly popular in recent years, but batteries can’t always keep pace with our ever-increasing demand for power. These personal electronics can just about do it all, but after a few hours of heavy usage, it’s time to recharge. Can we ever move past our addiction to the wall socket? Researchers in Germany have designed a tiny system embedded in a pair of shoes that effectively harvests the energy expended by the simple act of walking. With this…
