   The Energy Economy of Aerial Robots   As we all know some reasons for “Why don’t we see flying vehicles/machines around us in a sufficient quantity?”. One of the major reasons for this is the huge amount of energy required by this type of operation (flying)   To understand the reasons behind this energy consumption, first, we should have some knowledge of how aerodynamics works. Starting with the commonly known explanation of flight “The drag and thrust due to action of air”, which in simple terms means that “The flying object should produce enough thrust to counter its weight and drag offered by air resistance”. To obtain the required amount of thrust some technical specifications are to be met, this may include wing span to weight ratio, thrust offered by motors/propulsion system, aerodynamic design, etc. Now let us see the energy requirement and other details of different flying objects, 1)    Planes (or any flying object based on wings to produce thr...

  Modern Solutions for Radioactive Waste Nuclear energy has been one of the few advances we have made to lower our carbon footprint. Nuclear is the world's second largest source of low-carbon power (26% of the total in 2020). Even though nuclear energy is one of the most efficient ways of producing energy, it has been well opposed by many due to the many issues it brings with it, one of them being radioactive waste. Inside nuclear power plants, nuclear reactors and their equipment contain and control the chain reactions, most commonly fueled by uranium-235, to produce heat through fission. The heat warms the reactor’s cooling agent, typically water, to produce steam. The steam is then channeled to spin turbines, activating an electric generator to create low-carbon electricity. During this process, the power plants produce radioactive waste with varying levels of radioactivity which have to be disposed off properly to prevent any mishaps.  This includes its collection and sort...

   ZERO EMISSION ATOMIC ENERGY Haven’t we all thought of an ideal form of energy to run the world; one which would be clean & also more efficient? There exists such a source of energy: the zero-emission energy – Atomic energy. TARAPUR ATOMIC POWER STATION Atomic energy is a clean energy source with high reliability and high energy density. It has one of the smallest carbon footprints and may be our answer to positively impacting climate change and greenhouse gas emissions. Some experts take a step forward to even say that it is a contestant as one of our answers for the energy gap. But what exactly is atomic energy, the one solution to all our problems? Atomic energy or nuclear energy is the energy that is released in significant amount through the processes that affect the atomic nuclei, the dense cores of the atom housing protons and neutrons.  The two ways to release this energy are nuclear fission: where one larger atomic nucleus splits into two smaller atomi...

SAND BATTERIES   T he Future of Energy Generation & Storage (series)       Imagine walking on a beach at night, feeling the warmth of the sand under your feet. You might wonder how the sand can retain so much heat even after the sun has set. What if you could use this amazing property of sand to store and generate energy from renewable sources? This is not a fantasy, but a reality. In this blog, we will explore the fascinating technology of the sand battery , a new and promising solution for the green energy transition.   Solar and wind energy sources are becoming increasingly popular and cost-effective, however, they also present a challenge in terms of how to effectively store the surplus energy they generate when the need is low, as well as how to ensure a consistent and reliable supply of energy when the need is high. Conventional batteries are one of the solutions, however, they come with a number of drawbacks, such as their high cost, negativ...

VIRTUAL MIRRORS Unveiling the Magic of Digital Twins Hey, curious minds! Have you ever heard of digital twins? It may sound like something straight out of a sci-fi movie, but it's real, and it's fascinating! Whether you're an engineer, a healthcare professional, a city planner, or just someone eager to learn about cutting-edge technologies, this blog is for you. Buckle up and get ready for an exhilarating adventure into the mesmerizing world of digital twins, where reality seamlessly blends with virtuality. What Exactly are Digital Twins and How Do They Work? Just Imagine, you have a virtual clone of your car, your city, or even your own body! That's what digital twins are all about. They are virtual replicas of real-world objects, systems, or even people. But here's the magic—these virtual twins don't just sit there looking pretty; they actively simulate the behaviour of their real counterparts using real-time data. At the heart of the Internet of Things (IoT) ...
