Sensoria socks meter speed and identify injury

19.08.2014 |

Sensoria socks are infused with proprietary 100% textile sensors. They are paired with a Bluetooth Smart cool and detachable anklet that not only delivers superior accuracy in step counting, speed, calories, altitude and distance tracking, but goes well beyond that to track cadence, foot landing technique and weight distribution on the foot as you walk and run. Sensoria may help you to identifies injury-prone running styles (heel striking, overpronating, etc.), then leverages a mobile app to…

Holographic Displays Coming to Smartphones

15.08.2014 |

At Display Week in June, Ostendo demonstrated the culmination of nine years of work, an array of eight Quantum Photonic Imager (QPI) chips in a grid projecting three spinning green dice—one seemingly floating behind the display, one at chip level, and the third in front of the chips. “Almost every display you see emits light that goes everywhere,” says Hussein El-Ghoroury, Ostendo’s CEO. “In contrast, the QPI collimates the light to a very narrow angle before emitting it, so you can emit…

New Material Allows for Ultra-Thin Solar Cells

07.08.2014 |

Scientists at the Vienna University of Technology have managed to combine two semiconductor materials, consisting of only three atomic layers each. This new structure holds great promise for a new kinds of solar cell. Extremely thin, semi-transparent, flexible solar cells could soon become reality. At the Vienna University of Technology, students have managed to create a semiconductor structure consisting of two ultra-thin layers, which appears to be excellently suited for photovoltaic energy…

In Germany photovoltaic installations generate higher profits than onshore installations – although

05.08.2014 |

A current study by the Fraunhofer Institute for Systems and Innovation Research ISI deals with the revenues and profits that can be made by photovoltaic and onshore installations in Germany. The study illustrates that there are huge differences between the two regenerative energy sources and shows that photovoltaic installations generated significantly higher profits than onshore installations until 2012 although they produced less electricity overall. The study also points out striking…

NASA Launches Carbon-Tracking Satellite

05.08.2014 |

Delta II rocket carrying the OCO-2 satellite roared off the pad at Vandenberg Air Force Base in California. According to JPL, the OCO separated from the Delta II's second stage 56 minutes later and settled into an initial 690-kilometer-high orbit. If all goes well it will maneuver into a final 705-km orbit over the next month, putting it at the head of an international multi-satellite constellation of Earth-observing satellites known as the A-Train. OCO-2's contribution will be better…

How Tesla’s battery ‘Gigafactory’ could change everything — not just electric cars

04.08.2014 |

Tesla announced it is cooperating with Japanese industrial giant Panasonic to development a new, US-based battery production facility. Dubbed the Gigafactory, the facility will be able to produce batteries for as many as 500,000 EVs per year by the year 2020. The scale of the production is projected to be so large, in fact, that by 2020 the Gigafactory alone would produce as much battery capacity as the entire world produced in 2013. To be sure, the impact of the Gigafactory will positively…

British shale gas opens up

31.07.2014 |

The British government said Monday tapping into the country's shale natural gas reserves could bring substantial economic and environmental benefits. Business and Energy Minister Matthew Hancock said Monday the government must act carefully as it frees up access to shale reserves. "Unlocking shale gas in Britain has the potential to provide us with greater energy security, jobs and growth," he said in a statement. "As one of the cleanest fossil fuels, shale gas can be a key part of the UK…

Europe’s installed wind capacity will increase 64% by 2020

30.07.2014 |

Wind turbine installations in the European Union will increase 64% by 2020 compared to 2013 levels, according to data compiled by the European Wind Energy Association. A protracted economic crisis in Europe since 2009 and regulatory instability in a number of key European markets has contributed to EWEA’s new scenario for 2020. EU member states will reach a combined 192.4GW of installed capacity by the end of the decade with offshore installations accounting for 23.5GW of the total. ...read…
