Today’s Solutions: March 25, 2026

Radio frequency signals are all around us. They make it possible to have cell phone service, Wi-Fi, and digital broadcast television programming. For years and years, smart minds have been thinking about catching these radio frequency waves around us to recycle them for something else. Now, they have an idea. Engineers have developed technology that turns radio frequency (RF) energy into power for wearable and gadgets around your home. It’s called Freevolt, and it’s some kind of antenna that catches RF signals from the air and turns this signal into direct current. This energy is sent to a voltage booster, and eventually, a battery will be charged with this. The technology is promising. Eventually, it could even lead to networks of devices  that send data by reflecting signals to exchange information, without the need for batteries.
