    Algorithms/Data vs. Analysts/Reports: Fight!

    Quick, what’s the second most traded commodity in the world, after oil? Sorry, no: it’s not coffee. In fact, while hard data is scant, it may well be — of all things — carbon. No, really. According to the World Bank (PDF) , the global carbon market was worth a whopping 1.42 Facebooks US$142 billion in 2010. Mind you, it’s not like container ships weighed down to… Read More

    Could ‘Spider-Worm’ Silk Be The Next Supermaterial?

    Spiderman might soon lose his dominance in harnessing spider silk superpowers. Scientists from the University of Wyoming, the University of Notre Dame and Zhejiang University in China have genetically modified silkworms to spin stronger silk using spider genes.The new material could be used for everything from bulletproof vests to replacing tough plastics.

    Marine Solar Cells Make The Most Of Sun And Waves

    In an unusual hybrid, British industrial designer Phil Pauley created Marine Solar Cells that harness energy from both the sun and water. The web of energy generators capture energy off-shore, using a combination of floating photovoltaics and natural buoyancy displacement. Thanks to the reflective nature of water, the solar component’s efficiency is up to 20% greater than it would… Read More

    Chevy Volt To Get Low Emissions Perks In California

    Many in motoring are looking forward to an all-electric future, but as long as we’re burning fuel we’ll need to keep incentivizing low emissions. In California, a limited number of low-emissions vehicles are given stickers that let them travel in the HOV lanes, which residents know is a hell of a perk. Now Volt owners can get in on that action. Chevrolet is making a… Read More

    Electronic Flowerpot Takes The Guesswork Out Of Gardening

    Even though plants need only a few things to grow – water, air, light and minerals – maintaining the right proportions can make gardening feel like a high-maintenance hobby. Estonian company Click & Grow creates soilless, electronic flowerpots that do the work for you, providing the correct water and nutrient balance for indoor plants. For some, this may seem like a… Read More

    Design Competition Yields Bikes Of The Future

    Oregon Manifest, a nonprofit located in Portland, has been running a competition over the last few months in which students and pro teams work to create a next-generation city bike. This isn’t about speed (like the McLaren Venge) or concept design (like the Vienna Bike), but rather about creating a bike that provides the maximum amount of utility for someone looking to ditch their… Read More

    Electric Aircraft Competition Wraps, With $1.35M Prize For Plane That Out-Economizes A Prius

    A little more than a year ago, we posted about the possibilities of electric aircraft. At the time, we also mentioned an upcoming competition that would test the mettle of these flying batteries: the CAFE Green Flight Challenge. It’s a NASA event (and purse), sponsored by Google, which like the X-Prize aims to fund innovation through competition. Entrants would have to fly 200 miles in… Read More

    Why Did Solyndra Fail So Spectacularly?

    The spectacular failure of solar manufacturer Solyndra is being held up by some as a shining example of the Obama administration’s failure to properly manage government subsidies after its collapse left taxpayers with $535 million in federally guaranteed loans.┬áBut Solyndra’s failure on its own is not remarkable. There are always risks involved when you’re introducing… Read More

    More Details On MIT’s “Artificial Leaf” (And Video)

    Back in March, we heard about a breakthrough from MIT: an “artificial leaf” that produces pure oxygen and hydrogen gas, powered entirely by sunlight. The technology was described in yesterday’s edition of Science, and the team has released a video showing one of the devices in action. Read More
