Someday, cars may run on radio waves
Ambient Micro’s plan is to “develop a tiny device that harvests not only photons (visible light and invisible electromagnetic radiation), but also converts sound waves, vibrations and hot-cold temperature differences into power.”
Even though they are starting small, the company is also developing power sources for unmanned aerial drones. There is more than a hint in the article that tapping this free energy source will lead to truly creepy invasive spy machines, particularly little robotic spy flies that are, well, fly-sized. The technology also promises to have helpful benefits as well. While the article makes clear it is nowhere near practical to run electric cars on ambient radiation at this time, devices that tap ambient energy are another step forward in alternative energy.
