From www.hielscher.com: Ultrasonic waves of a high amplitude blow a candle out on more than a foot distance.

  • What kind of transducer did you use? Piezo or magnetic I would like to see if I can replicate it.

  • Piezoelectric. Magnetostrictive have a poor efficiency and convert much of the input energy into heat. In my humble opinion, magnetostrictive is not a very good driving system for ultrasonics.

    Piezoelectirc is more efficient and gives better control over vibration characteristics.

  • what frequency is that operating at?

  • approx. 20kHz

  • Can you bring the fire back with the sound?!

    Binjam

  • working on it ;-) will keep you updated

  • can it put out a much larger fire? so as to help in firefighting?

  • nice to show these strange applications

  • @TomInTheSky

    I got it, after years of hard work i finally got it.. ;)

    the solution is just to play the video reverse.

  • Could you make a video where you increase the amplitude slowly so we can see how it blows out?

  • what is that???

  • @cb2198 As Arthur C. Clark said, "Any sufficiently advanced technology is indistinguishable from magic."

    Magic is simply an understanding of laws and physics that western science has failed to recognize or misinterpret as something supernatural.

    People claiming to be anything they're not, is deceitful.

    But the fact remains that there is a small fraction of the human population that indeed can utilize natural electric and magnetic abilities that seem supernatural to others.

  • @TheRealVerbz

    Yes, magnetic energy is real. However, that does not mean you can use it to do magic, and claiming to do so is deceitful.

  • @cb2198 The Human body is a transmitter and receiver. Chi is another term for magnetic energy. Every time you flex your muscles, you are creating energy in the form of heat. Some people can consciously convert that heat into static electricity like a van de graff generator and then utilize that energy further.

    Most people are very deceitful, but the phenomenon is real. The only real case I believe on youtube is Johnny Chang because I've seen people do it in person and to me.

    Yeah, it's pretty much all transmitter junk... very clever, but very deceitful.

  • I WANT A FLYING SOUNDCAR!!!
