Imagine being able to power up your small electronics anytime, anywhere, and at no cost. Now you can with Freevolt, a technology developed by UK-based Drayson Technologies that converts energy from radio frequency signals into a never-ending stream of useable electricity. Leaning on RF energy harvesting to power the devices in our life would make use of something that is otherwise wasted, while bringing a lot of convenience and peace of mind to our lives.
