In this video, we will explain the history of Blockchain, what it is, how Bitcoin transactions happen, how Blockchain features like hash encryption, proof of work, and mining contribute to them, and how Blockchain technology is applied in real-world situations. Let’s dive into this video to learn the fundamentals of blockchain technology and how it works.
Lithium Supply Bottlenecks Risk Future of EVs | Tech News Briefing Podcast | WSJ
Lithium is a key component to the batteries in electric vehicles. But the part of the world with the largest known lithium deposits is stifling production of the mineral at a time when demand for it is growing. WSJ South America reporter Ryan Dube joins host Zoe Thomas to discuss what is causing the bottlenecks and how they could affect the global EV market.
This NEW Discovery Will Make Us Forget About Water Desalination!
Water is truly a precious commodity, and water scarcity is reaching critical levels in many parts of the world. There are now over one billion people who do not have access to clean water. The world’s demand for water is expected to increase dramatically in the coming years because of population growth, energy shortage, and pollution problems. However, a new breakthrough has been made that will vastly improve the quality and availability of potable drinking water. Grab a drink and relax as we show you this innovative discovery that makes water desalination obsolete.
Desalination is the process of producing drinking water by removing dissolved mineral salts in water. It’s a method that has been used for hundreds of years and has also attracted considerable investment over the past decade or so. But as many of us know now, it’s not all that reliable and it also poses a threat to our environment. Although the earth is made of 70% water, it appears that many countries all over the world experience water shortage – every year. In the absence of water, death is inescapable both in plants and animals. Tons of our daily activities take water as a chief resource. Farmers need water to grow plants; animals and humans need water to drink. Imagining a world without water would mean a place of desolation. Presently, the amount of clean water in the world is reducing and the cause is the spike in population growth. Current figures prove that 1.1 billion people lack access to water while 2.7 billion people lack water for one month a year, at least. World wildlife projects that by 2025, two-thirds of the world’s population will be hit and affected by water shortages. With these threatening issues, safer and quicker means of extracting water from the air are, in no doubt, expedient. Agricultural processes consume 70-80% of available water supplies as well as leakages and mismanagement of water resources. However, it is estimated that the Earth’s atmosphere holds 12 900km³ at any given time. That is an insane amount of water that is three times the amount that humans consume annually!
Are EVs really better for the climate?
Electric vehicles are rapidly growing in popularity as the number of different options has increased dramatically over the last couple of years and prices are beginning to move towards parity with internal combustion engine cars. But once all the carbon costs of extracting, processing and manufacturing are taken into account, how much lower is the overall lifetime carbon footprint of an EV compared to and ICE car? And for that matter, what’s the carbon footprint of all the other types of transport we use in modern society?
Running Neural Networks on Meshes of Light
Silicon Photonics represent a quantum leap in technological speed and power efficiency. One major issue when dealing with light is the fact that you’re reading the probabilities of the light waves. You run into quantum mechanics at this level. Light is sensitive to interference of the environment through quantum decoherence. I believe there will be a solution to this problem as our understanding of quantum systems evolves.
Solar Electric Cars: More Fact Than Fiction

How Was Video Invented?
I always wanted to know why film looked better than video. Moving electronic images have as long a history but were invented for a different purpose.
Tesla Turbine | The interesting physics behind it
The maverick engineer Nikola Tesla made his contribution in the mechanical engineering field too. Look at one of his favorite inventions — a bladeless turbine, or Tesla Turbine. The Tesla turbine had a simple, unique design, yet it was able to beat the efficiency levels of steam turbines at that time. Normal turbines are complex in design, with blades of complicated geometry and stator parts. Nikola Tesla once said the Tesla turbine is his favorite invention and he even claimed an efficiency level of 97% for this turbine. Let’s start a design journey to understand this interesting piece of technology, and towards the end we will also verify Tesla’s efficiency claim.
How does an Electric Motor work? (DC Motor)
Electric motors can seem very mysterious! How do they use electricity to start rotating? Let’s break it down step by step to understand how it works. Topics covered in this video: circuits, current, magnets, electromagnets, armature, commutator, brushes, stator, and rotor. This video only covers DC motors.
This Artificial Intelligence Just Proved It’s Better Than Humans After Being Observed Doing This
Since the early days of humankind, man has been driven to discover new things and develop new technologies. Just like how the wheel was once a novel concept but is now necessary for one’s daily life, many new technologies will become commonplace and essential in a few years. Recent developments could possibly revolutionise multiple industries. These ground-breaking findings have the potential to change the world.
