You recently got the chance to ask a group of MIT researchers questions about fusion power, and they've now finished writing some incredibly detailed answers. They discuss the things we've learned about fusion in the past decade, how long it's likely to take for fusion to power your home, the biggest problems fusion researchers are working to solve, and why it's important to continue funding fusion projects. They also delve into the specifics of tokamak operation, like dealing with disruption events and the limitations on reactor size, and provide some insight into fusion as a career. Hit the link below for a wealth of information about fusion.

linjaaho writes "Three major textbook publishers have sued a startup company making free and open textbooks, citing 'copyright infringement,' as the company is making similar textbooks using open material. From the article: 'The publishers' complaint takes issue with the way the upstart produces its open-education textbooks, which Boundless bills as free substitutes for expensive printed material. To gain access to the digital alternatives, students select the traditional books assigned in their classes, and Boundless pulls content from an array of open-education sources to knit together a text that the company claims is as good as the designated book. The company calls this mapping of printed book to open material "alignment" — a tactic the complaint said creates a finished product that violates the publishers' copyrights.'"
An anonymous reader writes "Amazon doesn't show off prototypes unless it is pretty confident about the tech, so you may be surprised to find the next Kindle is probably going to have a front-lit display. The lighting tech comes from a company they purchased back in 2010 called Oy Modilis. It specialized in such lighting and has patents related to whatever Amazon decided to use. The display is meant to be lit in a blue-white glow, and if it's anything like Flex lighting probably won't impact battery life too much. The question is, does anyone really want or need a light for their Kindle?"
An anonymous reader writes "I was looking at multimedia players from brands such as SumVision, Noontec and Western Digital. They all seem to be some device which accepts a USB hard-drive and commands from an IR remote control, and throws the result over HDMI. I have my own idea of what a hardware multimedia player should do (e.g. a personalized library screen for episodes, movies and documentaries; resume play; loudness control; etc.). I also think it will a good programming adventure because I will have to make the player compatible with more than a few popular codecs. Is this an FPGA arena? Or a mini-linux tv-box? Any advice, books or starting point to suggest?" There certainly have been a lot of products and projects in this domain over the years, but what's the best place to start in the year 2012?
New submitter artciousc writes with news that Amazon is dodging taxes in the UK. From the article: "Regulatory filings by parent company Amazon.com with the U.S. securities and exchange commission show the tax inquiry into the UK operation, which sells nearly one in four books sold in Britain, focuses on a period when ownership of the British business was transferred to a Luxembourg company." Clever trick there: "The UK operation avoids tax as the ownership of the main Amazon.co.uk business was transferred to a Luxembourg company in 2006. The UK business is now owned by Amazon EU Sarl and the UK operation is classed only as an 'order fulfilment' business." The HMRC is investigating the legality.
New submitter Volanin writes "The e-book versions of the Harry Potter series are being released through Pottermore, and J.K. Rowling has chosen to do a number of interesting things with them, including releasing them without DRM restrictions. 'One of the encouraging things about the Pottermore launch is that the books will be available on virtually every platform simultaneously, including the Sony Reader, the Nook, the Kindle and Google's e-book service. ... even Amazon has bowed to the power of the series and done what would previously have seemed unthinkable: it sends users who come to the titles on Amazon to Pottermore to finish the transaction.'"
New submitter MatthewVD writes "Boing Boing's Maggie Koerth-Baker, author of Before The Lights Go Out, writes that the era of giant hydroelectric projects like the Hoover Dam has passed. But the Department of Energy has identified 5,400 potential sites for small hydro projects of 30 MWs or less. The sites, in states as dry as Kansas, represent a total 18,000 MW of power — enough to increase by 50 percent America's hydro power. Even New York City's East River has pilot projects to produce power from underwater turbines. As we stare down global warming and peak oil, could small hydroelectric power be a key solution?"
Nuclear fusion power is the process of fusing light nuclei together to release energy, and ultimately, to put electricity on the grid. Today, we have six researchers from MIT's Plasma Science and Fusion Center here to answer your questions about fusion power, tokamaks, and public support and funding in the U.S. for this research. The Obama Administration's budget request for fiscal year 2013 is paying for the U.S. share of ITER construction out of the domestic program, starting with the closure of the MIT fusion lab. The interviewees are ready to answer technical and policy questions, so don't be shy! And, as always, please break unrelated questions into separate posts. Read on for information about the researchers who will answer your questions.
An anonymous reader writes "Forbes reports that a middle school teacher in South Carolina has been placed on administrative leave for reading sci-fi classic Ender's Game to his students. According to blogger Tod Kelly, '[A parent] reported him to the school district complained that the book was pornographic; that same parent also asked the local police to file criminal charges against the teacher. As of today, the police have not yet decided whether or not to file charges (which is probably a good sign that they won't). The school district, however, appears to agree with the parent, is considering firing the teacher and will be eliminating the book from the school.'"
benrothke writes "The Chicago Manual of Style (CMS), now in its 16th edition, is the de facto style guide for American writers. It deals with aspects of editorial practice, grammar, usage, document preparation and more. It's just one of many style guides for writers. The Microsoft Manual of Style, just released in its 4th edition, attempts to do for the technical writers what the CMS has done for journalists and other writers."

Hugh Pickens writes "Christopher Shea writes in the WSJ that physicists studying Google's massive collection of scanned books claim to have identified universal laws governing the birth, life course and death of words, marking an advance in a new field dubbed 'Culturomics': the application of data-crunching to subjects typically considered part of the humanities. Published in Science, their paper gives the best-yet estimate of the true number of words in English — a million, far more than any dictionary has recorded (the 2002 Webster's Third New International Dictionary has 348,000), with more than half of the language considered 'dark matter' that has evaded standard dictionaries (PDF). The paper tracked word usage through time (each year, for instance, 1% of the world's English-speaking population switches from 'sneaked' to 'snuck') and found that English continues to grow at a rate of 8,500 new words a year. However the growth rate is slowing, partly because the language is already so rich, the 'marginal utility' of new words is declining. Another discovery is that the death rates for words is rising, largely as a matter of homogenization as regional words disappear and spell-checking programs and vigilant copy editors choke off the chaotic variety of words much more quickly, in effect speeding up the natural selection of words. The authors also identified a universal 'tipping point' in the life cycle of new words: Roughly 30 to 50 years after their birth, words either enter the long-term lexicon or tumble off a cliff into disuse and go '23 skidoo' as children either accept or reject their parents' coinages."
hackingbear writes "A group of 22 Chinese authors have filed a claim against Apple, alleging its App Store sells unlicensed copies of their books. The Writers Rights Alliance, founded by Han Han, a young popular Chinese author and the worlds' most popular blogger, who is known for his cynical criticism of the government, petitioned Apple last year to stop electronic distribution of the writers' books and had earlier persuaded Baidu, China's largest search engine, to stop publishing their material on its Baidu Library product."
SonicSpike writes in with a story about the latest state contemplating raising revenues by taxing the net. "Downloading music, movies, e-books and Apps could soon cost Connecticut residents more as lawmakers consider a tax on digital downloads. The bill, proposed by the General Assembly's Finance, Review and Bonding Committee, would have consumers pay the 6.35% sales tax on any electronic transfer. Supporters say the bill would level the playing field for brick-and-mortar retailers in the state who are already required to charge Connecticut sales tax to consumers who purchase these products in their stores. About 25 states around the country have already begun taxing digital downloads."
An anonymous reader writes "Today Amazon announced that a science fiction writer has become the Kindle's all-time best-selling author. Last June Suzanne Collins, who wrote the Hunger Games trilogy, was only the fourth author to sell one million ebooks, but this month Amazon announced she'd overtaken all her competition (and she also wrote the #1 and #2 best-selling ebooks this Christmas). In fact, 29 of the 100 most-highlighted passages on the Kindle were written by Collins, including 7 of the top 10. And on a separate list of recent highlights, Collins has written 17 of the top 20 most-highlighted passages." It's pretty interesting to go through the top-100 list and look at the passages people think are worth highlighting. Taken out of context, many of them could be patched together and re-sold as a self-help book. None are quite so eloquent as #18 in the recent highlights.
