شركة لون تابعة لشركة الفابيت (غوغل) تعلن عن مشروع توفير الإنترنت للمناطق النائية.

يستخدم المشروع مناطيد على ارتفاع 12 الى 18 كم لإنشاء شبكة لاسلكية، وتستخدم المناطيد التيارات الهوائية في الستراتوسفير وبرامج لتغيير ارتفاعها

يحتوي المنطاد على بالونين، يتم ضخ الهيليوم من البالون الرئيسي في البالون الثانوي للصعود، ومن الثانوي للرئيسي للهبوط. كما يتم استخدام الواح الطاقة الشمسية للكهرباء، وفي حال الطوارئ يتم اسقاط وحدة الجهاز التي تزن 15 كجم بمظلة طوارئ، بعد رحلة قد تستغرق 100 يوم.

سيتعين على المستخدمين استخدام هوائيات اتجاهية للارتباط مع المناطيد حتى مسافة 40 كم منه.

What Is Bitcoin?

Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoin’s creator, Satoshi Nakamoto, originally described the need for “an electronic payment system based on cryptographic proof instead of trust.” Each and every Bitcoin transaction that’s ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. That’s by design: Core to their decentralized nature, Bitcoins aren’t backed by the government or any issuing institution, and there’s nothing to guarantee their value besides the proof baked in the heart of the system. “The reason why it’s worth money is simply because we, as people, decided it has value—same as gold,” says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.

However, analysts are positive on the stock now. “We have seen a huge downside movement in the stock due to the central electricity regulatory commission’s (CERC) order that seems to be negative from 2014-15 onwards but we cannot take a linear negative view on the stock and further downside movement on the stock is unlikely. Currently stock is underpriced. Investors can bet on it for a longer horizon," said Vivek Gupta, director research at CapitalVia Global Research.
