    lang-8.com is well known amongst intermediate/advanced language learners who are self-taught, but I thought I’d explain it for beginners. It is an amazingly useful site where you can blog or upload any text you’ve written in the language you’re learning. Many people use it as a diary, though I’ve seen people check essays and business emails there too.

    Once the text is uploaded native speakers of the language will check it for you. You return the favour by checking pieces of work written in your native language and correcting them. In this way everyone gets their work marked by a native speaker (often more than one person contributes so you can get several opinions too).

    It is massively helpful in improving all aspects of writing, but natural usage in particular (notoriously difficult for self learners to pick up when they are not in a native environment).

    ENDLESS ELECTRICITY: Here’s A Way Of Turning America’s Roads Into Gigantic Solar Panels

    There are about 31,251 square miles of roads, parking lots, driveways, playgrounds, bike paths, and sidewalks in the lower 48 states. If Julie and Scott Brusaw have their way, they will all someday be replaced with solar panels.

    For the better part of a decade, the Idaho couple has been working on prototyping an industrial-strength panel that could withstand the weight of even the largest trucks. They now appear to have cracked the formula, developing a specially textured glass coating for the panels that can not only bear tremendous loads but also support standard tire traction.

    By their reckoning, at peak installation their panelized roads could produce more than three times the electricity consumed in the U.S.

    The material could power electric vehicles through a receiver plate mounted beneath the vehicle and a transmitter plate is installed in the road.

    THIS IS UNBELIEVABLY IMPORTANT AND UNBELIEVABLY DISAPPOINTING THAT IT’S GOTTEN SUCH LITTLE ATTENTION.

    PEOPLE THINK ABOUT IT, JUST HOW MANY ROADS THERE ARE ALL OVER THE WORLD AND HOW MUCH ENERGY COULD BE PRODUCED USING THESE LIKE SERIOUSLY “THREE TIMES THE ELECTRICITY CONSUMED IN THE U.S”. IT’S NOT JUST GOING TO HELP REDUCE THE AMOUNTS OF GREEN HOUSE EMISSIONS, IT’S GOING TO CREATE JOBS IN THE COUNTRIES IT’S USED IN. IT HAS SO MUCH EXTRA STUFF IT’S UNBELIEVABLE HOW AMAZING THE ROAD COULD BE. 

    THESE PEOPLE ARE SAINTS, THEY’VE WORKED THEIR BUTTS OFF AND VOLUNTEERS HAVE WORKED JUST AS HARD TO GET TO THIS LEVEL BUT THEY STILL HAVE JUST UNDER $ 800,000 TO RAISE IN 15 DAYS. 

    THIS SORTA STUFF IS HOW WE’RE GOING TO CREATE A GREENER EARTH AND IT’S BEEN VIRTUALLY IGNORED BY TUMBLR. WE NEED TO SUPPORT THIS STUFF AND THESE SORTS OF PEOPLE WHO SELFLESSLY DEDICATE THEIR WORK TO CREATING A BETTER WORLD. 

    PLEASASASASASSSSSSEEEEEEEEEEEEEEE PEOPLE NEED TO SEE THIS.

    The Painful Truth About NASA’s Warp Drive Spaceship From A Physicist

    By Jason Torchinsky. June 16, 2014 12:00pm

    I’ll be honest — this is not the post I wanted to write. When NASA released their new renders of a hypothetical future faster-than-light spaceship, I wanted to believe that such a craft was mere decades away from reality. Then I made the mistake of asking someone much smarter than me about it.

    That much smarter someone is noted physicist Sean Carroll, a theoretical cosmologist specializing in dark energy and general relativity. He’s the sort of guy who knows about this kind of faster-than-light travel and warp bubbles and all this sort of exciting stuff. He’s a scientist immersed in this world, and as such he’s not going to sugarcoat the reality of the universe as it’s currently understood just because I want to join Starfleet.

    So, when I asked him for his take on just how feasible this warp-drive ship is, here’s how he responded:

    |
    |

    The Alcubierre warp drive is a very interesting arena for thought experiments to try to better understand general relativity and quantum field theory, but it should give you zero hope for actually building a spaceship some day. Some of the many problems are discussed on Wikipedia:

    http://en.wikipedia.org/wiki/Alcubierr…

    In short, it requires negative energy densities, which can’t be strictly disproven but are probably unrealistic; the total amount of energy is likely to be equivalent to the mass-energy of an astrophysical body; and the gravitational fields produced would likely rip any ship to shreds. My personal estimate of the likelihood we will ever be able to build a “warp drive” is much less than 1%. And the chances it will happen in the next hundred years I would put at less than 0.01%.

    But they are very pretty pictures! Would look great in a movie.

    |
    |

    Undaunted, I asked him if these assessments were taking into account the work that Harold White had done that dramatically reduced the energy requirements of the Alcubierre Drive. It looks like they weren’t, which gave me some hope, until I read the rest of his response:

    |
    |

    … note that “the mass-energy equivalent” of 700 kg (which I don’t believe for a second, I suspect you need much more) essentially means you need 350 kg of antimatter to combine with 350 kg of matter. From here:

    http://www.centauri-dreams.org/?p=22962

    they note that the current cost of producing 1 gram of antimatter is about $100 trillion. But, with completely unsupported optimistic estimates, you might get that down to $10 billion per gram. So, with the most wild-eyed pie-in-the-sky estimates, fuel alone will cost you $3.5 quadrillion — roughly the entire economic output of the world for forty years. Good luck with the Kickstarter!

    |
    |

    Okay. So maybe we all are getting a little more worked up than is merited over these spaceship renders. Forty years of global economic output is pretty expensive, even if I can talk them down, say, 10% or so.

    This blast of cruel, scientific reality did depress me for a bit, until I realized something. Something that Sean had not actually said. For being as pessimistic and coldly rational as he was — and as his role as a scientist all but demands him to be — it’s worth noting that he never actually said that this sort of faster-than-light travel is impossible.

    As far as I know, this may be the first point in history where that statement is true: a coldly scientific assessment of a faster-than-light spaceship did not meet with immediate dismissal as an impossibility. Sure, he pegged the odds of it happening at under 1%, but that’s 100% more possibility than we’ve ever had before.

    And while I suspect that this is the exact opposite take-away that Sean was going for, I’m actually strangely encouraged about the future (admittedly very very long-term) of a project like this. I respect the hell out of Sean Carroll, and I have no reason to believe his assessments are anything but sound. That’s why the fact that buried in all those reasons why this ship is currently impractical, that little nugget that suggests it’s theoretically possible is so tantalizing.

    Sure, we can’t do it now, but if humanity has proven anything it’s that given enough time, we tend to make impossible-seeming things real. Hand a Victorian engineer a shiny disc and tell him that on that disc, stored in tiny pits and peaks read with a beam of coherent light, are hundreds of songs and pictures and books, and he’ll look at you like you’re insane. Then tell him how we’ve already gone beyond that technology and people will throw away those discs like they were spoiled mutton.

    So, despite Sean’s very reasonable and rational criticisms, I hope NASA continues their research into Alcubierre/White drives. I hope they take these issues into account, think about them, work, imagine, develop, design, and eventually, whenever that is, figure out a solution.

    Sean’s probably correct, at least right now. But I’m still hopeful for the day he may be wrong. At least about this.
