The world's oceans cover more than 70% of Earth's surface. They're filled with currents, some much stronger than the fastest flowing large rivers. These currents can be harnessed as clean, marine ...

Renewable energy potential is not distributed evenly. Japan, for example, has sub-par solar potential and nowhere near the wind potential of Western Europe or the United States. It's also currently ...

The electric potential at any point in space made by a point charge Q is presented by the formula given below. It is the electric potential energy per unit charge. The electric potential at any point ...

Shini explores electric current, voltaic cells, and how we get electric charge. Electric current works like a river... kinda... Instead of flowing based on elevation ...

Electric current is electric charge in motion. It can take the form of a sudden discharge of static electricity, such as a lightning bolt or a spark between your finger and a ground light switch plate ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

The development of low-power methods for controlling a property of electrons known as spin could help to maintain the historic rates of progress that are occurring in computational power. Just such a ...

How can open ocean currents generate energy? Ocean currents contain kinetic energy that can be converted to electrical power using turbines. This is similar to offshore wind farms, or wind turbines ...
