LG Presents Solar Powered E-Book

MikeChino writes "At first glance, e-readers offer a great set of benefits over paper-bound books – they’re light, versatile, and a great alternative to lugging around a tote full of dead tree tomes on your next trip. However these new reading mediums have one glaring fault — can you imagine the frustration of running out of juice mid-sentence and halfway through Infinite Jest? LG's new solar e-book aims to address this issue by harnessing the sun's rays to power its display. The device features a 10 centimeter wide thin-film photovoltaic panel that can power the reader for a full day's worth of reading after 4-5 hours spent sitting in the sun."

      From the Source of all knowledge (ok, Wikipedia)

      http://en.wikipedia.org/wiki/Battery_charger#Prolonging_battery_life

      Most modern cell phones, laptops, and most electric vehicles use Lithium-ion batteries. Contrary to some recommendations, these batteries actually last longest if the battery is not fully charged; fully charging and discharging them will degrade their capacity relatively quickly. Degradation occurs faster at higher temperatures. Lithium batteries degrade more while fully charged than if it is only 40% charged. The conditions of high temperature combined with full charge are exactly the scenario occurring when a laptop computer is run on AC power. Degradation in lithium-ion batteries is caused by an increased internal battery resistance due to cell oxidation. This decreases the efficiency of the battery, resulting in less net current available to be drawn from the battery.

    Couldn't the aftermarket industry simply offer up a E-Book sleeve/cover that has a built in solar cell and stays connected to the reader's power jack and bring this 'breakthrough' to any other E-Book desired?

  6. Kinda pointless considering that by Zouden · · Score: 4, Informative

    The e-book itself is using an OLED display. This is different to the Kindle's eInk display which only requires power to update, so it has a battery life of several weeks. Chances are you'd be able to plug it in during that time, so there's not much need for a solar panel.

    LG are a big manufacturer of LCD and OLED screens. Adding a solar panel to their e-book is simply to make up for the fact that their display uses far more power than competing products.

      I'm not convinced by your efficiency argument. Decent paper is fairly energy-intensive to produce and so is shipping it. I've read around 200 books and quite a lot of papers (that I would otherwise have printed, read, and then thrown away) on my iLiad since I bought it. I suspect the tree cost of printing and shipping 200 books would be a lot more than the cost of making the device.

      Oh, and these were all creative commons or public domain. There are a huge number of classics on Project Gutenberg that I haven't (or hadn't) read, so no writers were harmed in the reading of these books (although Penguin Classics were slightly).

LG is only the latest to jump on the E-Book bandwagon, and I'm sure they won't be the last. The whole E-Book field is littered with junk announcements like this.

    Pocket calculators used to plug into the wall too. Then they had batteries and now solar. Having e-books go this way makes sense now power requirements are dropping.
    As for the "solar won't work at night" people - batteries exist and just need to be charged. The ironic thing for the "solar won't work at night" people is that the real killer application for photovoltaics at the moment is solar powered LED lights replacing kerosene lanterns in the third world.

    Since anecdotes are evidence: I own a Kindle and I can only think of once (in a year and a half) where I've been stuck unable to read. When the battery lasts two weeks and it only takes a couple of hours to charge, its really hard to run out, even when you're really bad about leaving things charged like I am. My phone is much more of a pain when it comes to keeping it charged.

    Kindles always spout how great it is you can read in the sun, because their eInk allows better viewing in direct light, but without that technology, this new device will be far less useful.

    Not to mention the rest of the device -- I'm sure you've seen what happens to plastic left in the sun! That clear plastic screen will look great once it turns yellow. Of course, I imagine it's a) mainly a gimmick and b) designed to die (so we can buy the newer model) long before sun damage...

    Given the most e-ink readers last about a week or more on a single charge, and can charge from a USB port, I'd say the chances of this being a gimmick are pretty high.
