A demonstration device powered by ionic wind. This one is quite heavy, and requires a 25 kV electronic power supply to operate. It works with an electrostatic machine too.

  • Is this the flyback transformer of a TV set? I was wondering if the same effect can be done by using the flyback of a plasma ball. Is 15kV enough to generate ionic wind?

  • @blqkvo The flyback is from a CRT monitor. 15 kV produces ionic wind and can power a lighter device. This one is too heavy.

  • Could you explain how does it work?

  • The device is connected to a high-voltage supply, and the pins attached to the balls produce ionic wind, that cause the rotation of the two bars fixed to low-friction bearings.
