Acoustic cracking of water with 42.8khz - Keely style.

Is anybody working in this area?

I notice that one can buy two ultrasound transmitters, pitched at 40khz, and a driving board for around 35.

The snag is that one needs to examine the board, see what it takes to adjust the existing fixed frequency.

But typing the number on the board, 13913887466 100W, does get us to what purports to be a circuit diagram - but without any 555 or similar chips.
