• A Lantern Powered by Gravity

    A design team in London has created a lamp powered by gravity called the GravityLight that could free poor, off the grid communities, from using costly and dangerous kerosene fueled lamps.

    Attached to the lamp, which is expected to retail for around $10 when it comes to market, is a bag that can hold about 20 pounds of sand or rocks and gravel which acts as the fuel when combined with gravity.

    The bag is build to descend under the weight of the materials which then triggers a set of gears that translate the force into power and light. It also works as a generator and can be used to charge radios and batteries.

    Since the GravityLight runs on available resources, once it's purchased there are no further costs to operate the lamp.

    According to a study published by the Guardian, in India alone 2.5 million people suffer severe burns from kerosene lamps every year and the cost can account for 20% of a household's income.

    GravityLight is currently raising money on Indiegogo through the

  • How “Big Data” Can Predict Your Divorce

    As our lives become more enmeshed in the digital playground, we reveal more information about ourselves than ever before in the history of mankind. Every online search, store purchase, Facebook post, Tweet or Foursquare check-in is creating a flood of data that, when organized and categorized and analyzed, reveals trends and habits about ourselves and society at large.

    In the last two years, humans have created 90% of all information ever created by our species. If our data output used to be a sprinkler, it is now a firehose that's only getting stronger, and it is revealing information about our relationships, health, and undiscovered trends in society that are just beginning to be understood.

    In his new book The Human Face of Big Data, author and photographer Rick Smolan and his partner Jennifer Erwitt use pictures, essays and startling facts to put our unprecedented output of information into perspective. Mr. Smolan sat down with us this week to discuss some of what he discovered

  • One Step Closer to Iron Man

    The Johnson Space Center in Houston and Tony Starks' Cliffside mansion in Malibu are both hubs of innovation, one real and one fictional. But with NASA's newest creation, the X1 Exoskeleton, reality appears to be following fiction.

    The 57 pound, 10 joint exoskeleton resembles a real life Iron Man suit, capable of increasing a humans own physical abilities. It's being developed to keep astronauts muscles active while they're in space, where the weightless environment can cause muscles to lose their strength, but during their research NASA realized the X1 could also help paraplegics walks on earth.

    The bodysuit is still in the prototype stages and won't be accompanying Scott Kelly, Gabby Giffords brother in law, who just volunteered to spend an entire year in space studying how the human body reacts to long term exposure to weightlessness.

    But the X1 Exoskeleton is being tested on paraplegics here on earth, and the results so far have been promising. To learn more we spoke with NASA
