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.

    The solar panel adds more bulk than a bigger battery would. It takes up a huge amount of real estate that could be occupied by another display. And, it really only helps you if you are planning on spending time reading outside - an impracticality in most parts of the United States, most of the time. Most of the year, outside is too hot, too cold, or infested with swarms of disease carrying mosquitoes. I go outside plenty of times when the weather is nice - but I'm active then. Sitting still and reading just makes you an easy target for the mosquitoes.

    If you're going backpacking or to the third world, it's more convenient to just bring a dedicated solar panel with battery pack and adapters for your gadgets.

    The only market for this device is eco-freaks with too much money and not enough sense.
