How People Began Using Fossil Fuels

Decomposing plants and other organisms, buried beneath layers of sediment and rock, have taken millennia to become the carbon-rich deposits we now call fossil fuels. These non-renewable fuels, which include coal, oil, and natural gas, supply about 80 percent of the world’s energy. They provide electricity, heat, and transportation, while also feeding the processes that […]

Energy & Electricity in Science : How Is a Photon Produced?

Hi, I’m Steve Jones and I’m going to tell you how a photon is produced. Now in an atom of course we have a nucleus but above the nucleus we have electrons. And it was discovered last century, the twentieth century that electrons can’t have any levels, they can only have specific levels of energy. […]

Energy & Electricity in Science : How Does a Solenoid Work?

Hi, I’m Steve Jones and I’m going to tell you how a solenoid works. Well first of all, what is a solenoid? It’s very simple, it is a coil of wire. This is usually copper wire and as you can see here, it’s coiled around like this, around some kind of former, this may be […]

Make a Tritium Nuclear Battery or Radioisotope Photovoltaic Generator

Warning: Tritium is radioactive but safe to handle as long as it is contained within its vials. Work carefully to avoid breaking the vials. If they do break, leave the area and ventilate it for a few hours to disperse the gas. Greetings fellow nerds. In this video we’re going to make a very simple […]

Energy & Electricity in Science : How Does an Electric Motor Work?

Hi, I’m Steve Jones and I’m going to explain how an electric motor works. Now I’ve drawn this diagram, it looks rather complicated but it isn’t really that complicated. There are two main elements. The first is this pair of magnets, one with a north here, the other with a south here. These are usually […]

Energy & Electricity in Science : How Does an Electric Circuit Work?

Hi I’m Steve Jones and I’m going to explain how an electric circuit works. Well first of all we have to remember that there are certain things which conduct electricity which we call conductors and there are others which don’t conduct which are called insulators. Now conductors and insulators you must know the difference between […]

Energy & Electricity in Science : How Does a Light Bulb Work?

Hi, I’m Steve Jones, and I am going to tell you how a light bulb works. Well, first of all we have to see the construction of the light bulb. In fact, the working part is what we call a filament which is a thin piece of metal, and this gets white hot. It glows […]

Energy & Electricity in Science : How Does an Electric Water Heater Work?

Hi. My name is Steve Jones, and I’m going to explain how a water heater works. Now, in this system, I have a cylinder. Usually in your house, you’ll find a cylinder. And the cylinder contains a large amount of water, maybe up to 200 liters, depending where you live. This water has to be […]

The Next 20 Years In Energy

Making long-term forecasts of energy use is hard. You think about global GDP, costs of production, the price of the commodity. In addition, now investors have to think about climate change and the impact that’s going to have on demand for oil, gas on all kinds of energy. This is why shale is one of […]

Energy & Electricity in Science : How Fast Does Light Travel?

Hi, I’m Steve Jones and I’m going to tell you how fast light travels. Well, light itself is a form of electro-magnetic radiation. Now, electro-magnetic radiation, it, comes in many forms. And starting at one end, we have radio and then we have we have microwaves. And next to microwaves we have infrared and then […]
