Radio de cuerda

The video tutorial discusses the role of batteries in powering devices and the challenges faced by people in remote areas who lack access to electricity grids and batteries. It introduces the invention of the clockwork radio, which uses a hand-wound spring to generate kinetic energy, converted into electrical energy to power the radio. This innovation allows people in remote locations to receive important information without relying on traditional power sources.
