Tom Scott - Why the US Army electrifies this water, 22082022

The Chicago and Sanitary Ship Canal is the path that invasive carp would take to reach the Great Lakes. So to stop them, the US Army Corps of Engineers has installed an electric barrier.

Tom Scott - Power, Politics and Pragmatism: The British National Grid, 15022016

Back in the 1920s, electricity was generated by hundreds of small companies in towns and cities across the country. They were all different and mostly incompatible: London alone had 24 voltages and 10 frequencies. How did we get from there to the billion-pound tunnel projects of today?

Practical Engineering - How do Electric Transmission Lines Work?

In the past, power generating plants were only able to serve their local areas. As power plants grew larger and further away from populated areas, the need for ways to efficiently move electricity over long distances has become more important. Stringing power lines across the landscape to connect cities to power plants may seem as simple as connecting an extension cord to an outlet, but the engineering behind these electric superhighways is more complicated and fascinating than you might think
