In this video Paul Andersen explains how energy can be harnessed was water moves through a turbine. Three types of systems are discussed in the video; run-of-the-water, impoundment, and tidal. Several advantages and disadvantages of dams...

Wind is an ever increasing source of power worldwide, which means wind farms continue to be constructed. And choosing where to place those farms seems straightforward, but it might not actually be best to place the in the windiest places!

At the INK Conference, Arvind Gupta shares simple yet stunning plans for turning trash into seriously entertaining, well-designed toys that kids can build themselves -- while learning basic principles of science and design.

Despite the rise of renewable energy, the backbone of the power grid is fossil fuels. Adapting the grid to green energy sources is more complicated than flipping a switch.

What if we could capture pollution in the air around us and turn it into something useful? Inventor Anirudh Sharma shares how he created AIR-INK, a deep black ink that's made from PM 2.5 pollution. See how he hacked together a clever way...

In this episode of Crash Course Physics, Shini talks to us about how power gets to our homes. It's kind of amazing when you think about it and much more complicated than it may seem!

In this video Paul Andersen explains how electromagnetic induction occurs when the magnetic flux of an object changes. The magnetic flux is product of the surface area perpendicular to the magnetic field and the magnetic field strength....

Cow manure contains methane, a potent greenhouse gas. Farmers who collect and burn methane keep it out of the atmosphere while generating clean electricity.

Pupil outcome: I can reflect on the importance of electricity in my life and I can record how I use it for everyday activities. Key learning points: - Most electricity is produced in power stations and then cables deliver the energy to...

Today, Helper Cars are ready to build a new wind turbine. The logging truck has to deliver three blades for the turbine. The police car and the monster truck come with the logging truck and monitor the safety. The blades have arrived,...
