We've all heard of electromagnetic waves, but have you ever considered a wheel that produces them? Imagine it: a silent, spinning orb radiating energy in every direction. It's hard to believe something as mundane as a wheel can create something as sophisticated as radio signals. But with the help of modern technology and a bit of imagination, we're able to turn wheels into electromagnetic powerhouses. This electrifying concept was recently demonstrated at a French tech show. Scientists displayed a regular bike wheel attached to a magnet which spun in response to the user's input, thereby producing sound waves as energy resonated within it. We were fascinated by this innovative application of our natural world. The simplicity and beauty of it make you wonder why no one ever thought of using something so fundamental like rotation as the power source before.
