Can researchers built a new kind of battery powerful enough to fuel an electric airplane? MIT's Technology Review profiles a company co-founded by MIT materials science professor Yet-Ming Chiang: He and his colleague, Venkat Viswanathan, are taking a different approach to reach their next goal, altering not the composition of the batteries but the alignment of the compounds within them. By applying magnetic forces to straighten the tortuous path that lithium ions navigate through the electrodes, the scientists believe, they could significantly boost the rate at which the device discharges electricity. That shot of power could open up a use that has long eluded batteries: meeting the huge demands of a passenger aircraft at liftoff. If it works as hoped, it would enable regional commuter flights that don't burn fuel or produce direct climate emissions...

The initial plan is to develop a battery that could power a 12-person plane with 400 miles (644 kilometers) of range -- enough to make trips from, say, San Francisco to Los Angeles, or New York to Washington. In a second phase, they hope to enable an electric plane capable of carrying 50 people the same distance.... Last year, the company announced plans to deliver a line of "hybrid to electric" aircraft with room for 12 passengers in 2022. At launch, the company intends to offer a hybrid plane with a gas turbine and two battery packs capable of flying around 700 miles (1,127 kilometers), as well as an all-electric version with three battery packs and a range of less than 200 miles....But crucially, the plane itself is expected to feature an open architecture that allows owners to switch out these modules over time, enabling them to upgrade to better batteries developed in the future or shift from hybrid to all-electric operation.
About 2% of the world's CO2 emissions come from air travel, and it's one of the fastest-growing sources of greenhouse-gas pollution. "More than a dozen companies, including Uber, Airbus, and Boeing, are already exploring the potential to electrify small aircraft," the article points out, "creating the equivalent of flying taxis that can cover around 100 miles (161 kilometers) on a charge. The hope is that these one- or two-passenger vehicles -- in most cases envisioned as autonomous vertical takeoff and landing aircraft -- could shorten commutes, ease congestion, and reduce vehicle emissions."

But with less ambitious batteries, "these would largely replace car rides for the rich, not displace air travel."

Of the partnership, Roadtrip Nation co-founder Mike Marriner said, "Roadtrip Nation is proud to partner with Microsoft's YouthSpark initiative not only to inform others of the many career routes one can take with a computer science background, but also to engage in the much-needed conversation of diversifying the tech field with more pluralistic perspectives." YouthSpark is part of Microsoft's National Talent Strategy (pdf), which the company describes as "a two-pronged approach that will couple long-term improvements in STEM education in the United States with targeted, short-term, high-skilled immigration reforms." The Official Microsoft Blog reports that filming of Code Trip began this week, with the three students traveling around the country to speak with leaders including Hadi Partovi, the co-founder of Code.org and 'major supporter' of FWD.us, who coincidentally once reported to Microsoft CEO Satya Nadella, and is the next door neighbor of Microsoft General Counsel Brad Smith and a jogging partner of Steve Ballmer.

"Currently, just 25 states and the District of Columbia allow computer science to count as a math or science graduation requirement," explained the press release. "Because boys get more informal opportunities for computing experience outside of school, this lack of formal computing education especially affects girls and many youth of color." HUD, the press release added, has joined the Commitment to Action to help extend the program's reach in partnership with public housing authorities nationwide and provide computing access to the 485,000 girls residing in public housing. "In this Information Age, opportunity is just a click on a keyboard away. HUD is proud to partner with NCWIT to provide talented girls with the skills and experiences they need to reach new heights and to achieve their dreams in the 21st century global economy," said HUD Secretary Julian Castro, who coincidentally is eyed as a potential running mate for Hillary Clinton, whose daughter Chelsea is the Clinton Foundation's point-person on computer science. Last year, Chelsea Clinton gave a keynote speech at the NCWIT Summit and appeared with now-U.S. CTO Megan Smith to help launch Google's $50 million girls-only Made With Code initiative.

theodp writes "In July, the Association for Computing Machinery announced it was partnering with Code.org, with ACM contributing funding and its Director of Public Policy to Code.org in a push to 'ensure that every K-12 student in the US has the opportunity to study computer science.' Interestingly, joining others questioning the conventional Presidential wisdom that everybody-must-get-code is the Communications of the ACM, which asks in its February issue, Should Everybody Learn to Code? By the way, Code.org is bringing its Hour of Code show to the UK in March. The new National Curriculum for England that is to be taught in all primary and secondary schools beginning in September includes a new emphasis on Computer Science curricula, said to have been sparked by a speech given by Google Chairman Eric Schmidt in 2011."

James Logan founded MicroTouch Systems in the 80s and served on the on the Board of Directors of Andover.net, the company that acquired Slashdot back in 1999, but it is the company he founded in 1996, Personal Audio, that has garnered him much attention recently. Personal Audio sued Apple in 2009 for $84 million, claiming infringement on patents for downloadable playlists. Apple eventually lost the case and a jury ordered them to pay $8 million in damages. More recently, Personal Audio has filed suit against several prominent podcasters claiming that “Personal Audio is the owner of a fundamental patent involving the distribution of podcasts.” The EFF challenged the patents calling the company a patent troll saying, "Patent trolls have been wreaking havoc on innovative companies for some time now." The vice president of licensing for the Texas company counters that the EFF is working for "large companies against a small business and a couple of inventors," adding "Every defendant calls every plaintiff a patent troll. I've heard IBM called a patent troll. It's one of those terms everyone defines differently." Mr. Logan has agreed to answer your questions about his company and his patents. As usual, ask as many as you'd like, but please, one question per post.

derekmead writes "According to a new study (PDF) from Pew Charitable Trusts, China was the world leader in clean energy investment in 2012. The U.S., meanwhile, saw its grip loosen on many of the clean energy technologies it developed. According to the research, total clean energy investment totaled $269 billion worldwide last year, a decline from 2011's record high of $302 billion. However, clean energy investment in the Asia and Oceania markets grew by 16 percent to $101 billion. In terms of investment — which is an indicator that a country or region has offered compelling projects, struck a good regulatory balance, and has a strong economy — that makes Asia the epicenter of the global clean energy market. The Pew researchers thus labeled the U.S. clean energy sector as 'underperforming,' largely for a trio of reasons. First, China's boom and manufacturing prowess has taken investment away from the U.S.. Second, the U.S. regulatory environment for clean energy is horrifically unstable (as is the regulatory environment as a whole) as politicians battle over budget rhetoric. Finally, the U.S. has failed to capitalize on its innovation prowess and develop its clean energy manufacturing sector to its full potential." They do not count nuclear as clean, but including nuclear would only widen China's lead over everyone else (they almost have their first new AP1000 ready and are building lots more).

New submitter SIGSTOP writes "The LINC [OpenFlow 1.2 software-based] switch has now been released as commercial friendly open source through the FlowForwarding.org community website, encouraging users and vendors to use LINC and contribute to its development. The initial LINC implementation focuses on correctness and feature compliance. Through an abstraction layer, specialized network hardware drivers can be easily interfaced to LINC. It has been implemented in Erlang, the concurrent soft-real time programming language invented by Ericsson to develop their next generation networks."

New submitter dell623 writes "A patent lawsuit (PDF) by patent licensing firm Digitude Innovations curiously targeted all mobile manufacturers except Apple. A TechCrunch story has revealed that the patents used were transferred from Apple via a shell company to DI, and appear to cover features found in virtually all smartphones. The lawsuit even extends to companies that don't make Android phones, like Nokia and RIM, and to Android OEMs that Apple have not directly sued yet, like Sony. The business model of DI clearly implies that Apple would benefit financially from the lawsuit as a company that contributed patents to DI's portfolio."

TechDirt has a follow up to a case they covered back in October where a law firm was trying to claim a copyright on the cease-and-desist letters they sent out. Public Citizen poked a number of holes in this claim and invited the lawyers to "try it." Well, unfortunately the lawyers decided to bite and what's more, they actually got a judge to buy it. The news was announced by the victorious lawyer who now claims he can sue anytime someone posts one of his cease-and-desist letters. "The copyrighting of cease-and-desist letters is an easy way for law firms to bully small companies who have committed no wrong, but who have no real recourse to fight back against an attempt to shut them up via legal threat. Until today, many companies who were being unfairly attacked by companies and law firms misusing cease-and-desist letters to prevent opinions from being stated, had a reasonable recourse to such attacks, and could draw attention to law firms that used such bullying tactics to mute any criticism."

ribuck writes "Equipment powering the internet accounts for 9.4% of electricity demand in the U.S., and 5.3% of global demand, according to research by David Sarokin at online pay-for-answers service Uclue. Worldwide, that's 868 billion kilowatt-hours per year. The total includes the energy used by desktop computers and monitors (which makes up two-thirds of the total), plus other energy sinks including modems, routers, data processing equipment and cooling equipment."

Roland Piquepaille writes "About eighteen months ago, I told you about a tricycle with square wheels which needed a specially designed road. But now, Distributed Robotics, a company from Troy, N.Y., is developing robots with square wheels which don't need specific roads. These new 'cars' propel themselves on flat surfaces by taking advantage of gravity. This might sound crazy, but the inventors think it could lead to new robots and toys, and more generally to new micro-machines or MEMS applications."

Inzite writes "EnterNetica R&D is working on a new spherical video technology for capturing and presenting full 360 degree scenes using a 180 degree lens, by adaptively predicting the camera's surroundings. Video extrapolation techniques have been proposed in the past, but this is the first time I've heard of an entire hemisphere of the video image being "guessed". The article also talks about feature film presentation using fully-immersive video in the future."

deeptrace writes "A group of SF writers all submitted purposely awful stories to a publisher that purported to publish only selected high quality works. They created the worst story they could come up with, and it was accepted for publication." Their press release is pretty funny -- and if you'd like a sample of their insane prose, it's available through the book's Lulu site. (Where, Yes, you could also buy the whole thing.)

Roundeye writes "So the folks at monsterpatterns.com dumpster-dive to get envelopes containing discontinued sewing patterns and sell the envelopes via their website. The sewing pattern company McCall invoked the DMCA to get the site shut down. Monsterpatterns is now suing to protect their 'fair use rights' to advertise and sell the discarded patterns. You might recall that this isn't the first time the sewing industry has cracked down on bootlegging grandmas and their suppliers."
