The Tech Castle

In the ever-connected world that we live in today, it's odd to know that certain spots don't yet have reliable internet - one of which are airplanes. But if SpaceX has anything to do with it, it'll make that happen. What is SpaceX? SpaceX is a private spaceflight company that puts satellites into orbit and delivers cargo and, more recently, crew to the International Space Station (ISS). Founded by Elon Musk. SpaceX is reportedly in talks with "several airlines" about providing their aircraft with Starlink satellites' internet network to provide travellers onboard flights with faster internet speed. What is Starlink? Starlink is the company's capital-intensive project to build an interconnected internet network with thousands of satellites, known in the space industry as a constellation. It has already launched 1800 satellites out of the planned 4,440 and plans to provide global coverage with high-speed broadband internet. The service initially was meant fo

  Mobile Dialysis Startup Eyes Human Trials In 2022 This past year, three sheep in Canada have been wearing their kidneys on their sleeves. Or more aptly, in jackets of their fluffy backs. These three sheep are part of an ongoing animal study run by the Buffalo, New York-based startup Qidni Labs, a company pursuing waterless and mobile blood purification systems. Qidni labs were also a winner of the KidneyX 2019 Summit for developing an air removal system for a wearable renal therapy device.  The jackets are a prototype of Qidni’s mobile hemodialysis machine called Qidni/D. The idea behind it is that the machine is significantly smaller than the traditional hemodialysis setup and it uses fewer fluids, allowing patients to be more free and mobile. As per the records many people in the world are facing some type of chronic kidney disease and over time this disease could progress into kidney failure, at which point the patients are recommended to undergo dialysis or receive a transplant. 

                      A DEEP DIVE INTO CRYPTOCURRENCY   What is Cryptocurrency?   A cryptocurrency is a form of payment that can be exchanged online for goods and services. Many companies have issued their own currencies, often called tokens, and these can be traded specifically for the good or service that the company provides. Think of them as you would arcade tokens or casino chips. You’ll need to exchange real currency for the cryptocurrency to access the good or service.   Cryptocurrencies work using a technology called a blockchain. Blockchain is a decentralized technology spread across many computers that manage and record transactions. Part of the appeal of this technology is its security.   Cryptocurrencies can act like real money—in a sense, they are real money—but they take a digital monetary form and are not managed or governed by any central authority. A true product of the digital age, cryptocurrencies operate without the involvement of banks, governments, or any middlema

  What is Li-Fi ? LiFi( light fidelity) is a wireless technology  which carry the key to solving challenges faced by 5G. LiFi can transmit at multiple gigabits, it is more reliable, virtually interference free and uniquely more secure compared to radio technology like Wi-Fi or cellular.   LiFi is a mobile wireless technology that makes use of light rather than radio frequencies to transmit data. The technology is upheld by a global ecosystem of companies driving the adoption of LiFi, the next generation of wireless that is ready for seamless integration into the 5G core.   How is works ? Radio frequency communication requires radio circuits, antennas and complex receivers, whereas LiFi is much easier and uses direct modulation systems similar to those used in low-cost infrared communications devices such as remote control units. LED light bulbs have high intensities and therefore can achieve very wide ranging  data rates.   Benefits : Speed and Bandwidth - The lig
