We all know the words around electricity, “charge,” “positive,” “battery”, and more. But where do they come from and what do they really mean? Let the history of these words illuminate the physics of electric phenomena.
Can nanotechnology solve our battery production problem?
From smartphones and laptops to the rapidly growing EV market, we need an incredible amount of lithium-ion batteries to make it all work. Materials like lithium are difficult and time-consuming to mine and extract … and can have a major impact on the environment. Can nanotechnology solve our lithium extraction and mining problem? And maybe even help with solid-state batteries? I talk to Teague Egan from EnergyX about some interesting advancements in nanotech, metal-organic frameworks, and more.
What is CURRENT– electric current explained, electricity basics
What is electric current, in this video we learn what is electric current covering amps, coulombs, voltage, parallel and series circuits, multimeters, resistors, fuses and circuit breakers to learn how electricity works.
How does a Transformer work – Working Principle electrical engineering
How does a transformer work. In this video we’ll be looking at how a transformer works covering the basics with transformer working animations and explanations to understanding the working principle. We’ll cover how to creating a magnetic field with electricity, Why only Alternating current can only be used in transformers, How a basic transformer works, step up and step down transformers, transformer connections and windings, Three phase transformers, Delta Wye connections.
How The Next Batteries Will Change the World
Silicon Valley is about to commercialize revolutionary technology that will enable huge breakthroughs in the battle against global warming.
Elon Musk – Solar is the Future
In this video Elon Musk goes into details about solar power ant potential of it. Elon basically says that solar is the future and it is already here. This is a very interesting topic so check it out.
Micro Hydropower : Turbulent Turbines
Hydropower has been with us for millennia, but the 20th Century race to build huge centralised hydropower dams in many parts of the world has caused untold environmental damage. Now a new micro-hydropower technology is working with the natural flow of water and wildlife rather than against it, to bring much needed constant baseload power to off grid areas in remote areas of developing nations.
Basic Electricity – Power and watts
A tutorial on electrical power and watts. A practical example of light bulb power measurement is shown as well as a demo how to calculate appropriate resistor sizes.
Explaining how the national grid works
In the UK there are over 4,474 miles of overhead electricity lines providing power to Britain’s homes. Using a model I demonstrate how the National grid works.
Liquid Metal Batteries. Are they an economic possibility?
Liquid metal batteries are being hailed by some as the most transformative and revolutionary energy storage technology since John B. Goodenough came up with lithium ion batteries several decades ago. But the road from laboratory to full scale production has been a long and winding one, and commercial success is still by no means guaranteed. So, will liquid metal batteries change the world?
