Hugh Pickens writes writes “Gosia Wonzniacka reports that farmers in Fresno County, California, supported by university experts and a $5 million state grant, are set to start construction of the nation’s first commercial-scale bio-refinery to turn beets into biofuel with farmers saying the so-called ‘energy beets’ can deliver ethanol yields more than twice those of corn per acre because beets have a higher sugar content per ton than corn. ‘We’re trying to reduce greenhouse gas emissions and to shift our transportation fuels to a lower carbon content,’ says Robert Weisenmiller. ‘The beets have the potential to provide that.’ Europe already has more than a dozen such plants, so the bio-refinery would resurrect a crop that has nearly vanished. The birthplace of the sugar beet industry, California once grew over 330,000 acres of the gnarly root vegetable (PDF), with 11 sugar mills processing the beets but as sugar prices collapsed, the mills shut down. So what’s the difference between sugar beets and energy beets? To produce table sugar, producers are looking for sucrose, sucrose and more sucrose. Energy beets, on the other hand, contain multiple sugars, meaning sucrose as well as glucose, fructose and other minor sugars, called invert sugars. To create energy beet hybrids, plant breeders select for traits such as high sugar yield, not just sucrose production. America’s first commercial energy beet bio-refinery will be capable of producing 40 million gallons of ethanol annually but the bio-refinery will also bring jobs and investment, putting about 80 beet growers and 35,000 acres back into production.” Read more of this story at Slashdot.

Next-Gen Intel Chip Brings Big Gains For Floating-Point Apps
An anonymous reader writes “Tom’s Hardware has published a lengthy article and a set of benchmarks on the new “Haswell” CPUs from Intel. It’s just a performance preview, but it isn’t just more of the same. While it’s got the expected 10-15% faster for the same clock speed for integer applications, floating point applications are almost twice as a fast which might be important for digital imaging applications and scientific computing.” The serious performance increase has a few caveats: you have to use either AVX2 or FMA3, and then only in code that takes advantage of vectorization. Floating point operations using AVX or plain old SSE3 see more modest increases in performance (in line with integer performance increases). Read more of this story at Slashdot.

We Should Be Allowed To Unlock Everything We Own
An anonymous reader writes “When cell phone unlocking became illegal last month, it set off a firestorm of debate over what rights people should have for phones they have legally purchased. But this is really just one facet of a much larger problem with property rights in general. ‘Silicon permeates and powers almost everything we own. This is a property rights issue, and current copyright law gets it backwards, turning regular people — like students, researchers, and small business owners — into criminals. Fortune 500 telecom manufacturer Avaya, for example, is known for suing service companies, accusing them of violating copyright for simply using a password to log in to their phone systems. That’s right: typing in a password is considered “reproducing copyrighted material.” Manufacturers have systematically used copyright in this manner over the past 20 years to limit our access to information. Technology has moved too fast for copyright laws to keep pace, so corporations have been exploiting the lag to create information monopolies at our expense and for their profit. After years of extensions and so-called improvements, copyright has turned Mickey Mouse into a monster who can never die.’ We need to win the fight for unlocking phones, and then keep pushing until we actually own the objects we own again.” Read more of this story at Slashdot.

Walgreens To Build First Self-Powered Retail Store
MojoKid writes “We hear about green deployment practices all the time, but it’s often surrounding facilities such as data centers rather than retail stores. However, Walgreens is determined to go as green as possible, and to that end, the company announced plans for the first net zero energy retail store. The store is slated to be built at the corner of Chicago Avenue and Keeney Street in Evanston, Illinois, where an existing Walgreens is currently being demolished. The technologies Walgreens is plotting to implement in this new super-green store will include solar panels and wind turbines to generate power; geothermal technology for heat; and efficient energy consumption with LED lighting, daylight harvesting, and ‘ultra-high-efficiency’ refrigeration.” Read more of this story at Slashdot.

9 Incredible Uses for Graphene
Graphene is amazing. Or at least, it could be. Made from a layer of carbon one-atom thick, it’s the strongest material in the world , it’s completely flexible, and it’s more conductive than copper. Discovered just under a decade ago, the supermaterial potentially has some unbelievable applications for us in the not so distant future. More »

Eat a Banana to Remedy Over-Caffeination
Getting too juiced up on caffeine happens. Maybe you made a pot and nobody wanted it but you. Perhaps you got lost in a great conversation. In any case, baristas and amateur nutritionists suggest one possible remedy: eat a banana. Yes, a banana. More »

Graphene supercapacitors could make batteries obsolete
A battery can hold a lot of energy, but it takes a long time to charge it. A capacitor can be charged very quickly, but doesn’t hold a comparable amount of energy. A graphene supercharger is the best of both: it takes just seconds to charge, yet stores a lot of energy. Imagine being able to charge your spent laptop or phone battery in 30 seconds, and your electric car in a few minutes. Also, unlike batteries, Graphene supercapacitors are non-toxic. The Nobel Prize was awarded to the inventors of Graphene in 2010. Wikipedia defines Graphene as a “substance composed of pure carbon, with atoms arranged in a regular hexagonal pattern similar to graphite, but in a one-atom thick sheet. It is very light, with a 1-square-meter sheet weighing only 0.77 milligrams.” (via Tony Moore at the Boing Boing G+ community )

Turning a Kindle Fire HD Into a Power Tablet
jfruh writes “The Kindle Fire HD is in theory a powerful device at a reasonable price — but its Android-based OS is so oriented towards Amazon’s ecosystem that it can be tricky to unlock its full potential. Still, with a little savvy you can get underneath the covers, improving battery life, getting full access to cameras and other devices, and even listening to music you’ve purchased through iTunes.” Read more of this story at Slashdot.

First Impressions Inside the Project Holodeck VR Game World
Hesh writes “The space-pirates themed Project Holodeck game is a VR game that is initially targeted for the Oculus Rift and will marry VR with a world so interactive and immersive that it feels like you can reach out and touch it. Ben Lang over at RoadToVR recently got a chance to sit down with the team and try it out. He came out extremely impressed with how immersive the experience was: ‘…at one point I needed to set the Razer Hydra controllers down to adjust my helmet and I nearly tried to set them down on a virtual table next to me. There was no table in real life — had I not quickly realized what I was about to do, I would have dropped the controllers straight onto the floor below.'” Read more of this story at Slashdot.
