INTRODUCTION TUNE IN A song plays softly from the speakers of a car speeding down the highway The driver clicks off the radio but the radio waves broadcasting the song are still present invisible in the night air In a nearby building two scientists are harvesting or collecting radio waves that are not being used The scientists have discovered that the energy from unused radio waves can power small devices such as smoke alarms Instead of letting this energy go to waste they work to turn these radio waves into usable power Just like all star inventors years before them these scientists are investigating the potential of radio waves This exciting modern work could be just as important as the invention of the first radio Radio technology has come a long way since this early 1914 radio model
