Ultrasonic waves and other soundwaves can use to charge nanotechnical tools. (And The futuristic self-organizing material can automatically create physical 3D holograms. )

Credit: Korea Institute of Science and Technology (KIST)"(ScitechDaily/Using Ultrasonic Waves To Charge Underwater and Body-Implanted Electronic Devices) The similar systems can use to charge underwater and even airborne devices. Wirelessly Charging Body Implanted Electronic Device Nanotechnology allows making the of new types of chargers that are safe to use. The idea is to use sound waves for making electricity for the nanomachines or larger electric devices. The ultrasonic waves are one version of sound waves. The soundwaves and especially ultrasonic waves are pressure impulses. And pressure impulses can use to make electricity. The first version of this system bases the crystals. When nano-size quartz crystals are stressed by using pressure impulses. That small crystal creates electricity. In another version, the small-size turbines are starting to rotate when
