Sonic Disassociation

This work was inspired by work done by Jerry Decker. According to his research in to the works of John W. Keely. Keely was able to cause the disassocition of water using sound, at a particular frequency 42.8 kHz. Above is 2 pictures of the Piezo Electric transducer, submerged in water, the top picture is before I turn the tranducers on.. notice, there are no bubbles.. On the bottom picture, when I have the transducer tuned between 32-42 kHz, bubles start to form on the surface of the plastic.. I haven't been able to verify weather these are cavition (steam/water vapor), trapped air coming out of solution, or infact if it is H2 and O2 disassocitated, as of yet. The formation of the bubles is definatly not an electrical phenominon, since they form on the plastic, where the sound is most intense (and away from the electrodes). This seem to be further evidence to back up the work of Keely. Below is a link to Keely Net where Jerry Decker talks a little about the disassocition frequency of water.

Above is a nebulizer unit powered by a switching fet power supply which I had invented. Once water is poured on top of the nebulizer disc, it will immediatly well up in the center, and produce a stream of fog. The nebulizer disc is held in a PVC pipe adaptor with a spring pressing it against the top contact.

Here is the actual nebulizer dics. A special thank to Bob De Maria for sending the nebulizer discs and ultrasonic microphones to allow me to experiment with and for the insightful communications and exchange of ideas... Without which, I would not have been able to bring these experiments to you. The nebulazer has a resonance frequency around 1.3 to 1.7 MHz to produce the fog as pictured above.

Pictured, On the top is the driver circuit used to supply the power to the Piezo electric units.. It utilized an n an p channel fet (NTE2380, NTE2381) to provide the high power, high frequency electrical energy to the Piezo electic transducers... I found that in order for the power driver circuit to opperate above about 1MHz, it needed a 1:1 high frequency transformer to match the input of the driver circuit. Even with this, the range is only extended to about 2.5 MHz due to limitations of the FET's.

Here is something unusual I discovered while working with with unit. Above, bubbles form in front of the submerged nebulizer unit, at about 755 kHz. This is unusual, because the bubbles are trapped in a lattice like fomation (due to the sound) and wiggle around as if they were suspended in jellow or as if the water had solidified. Once the power is turned off, the bubles immediatly dissipate. There are other resonances at about that cause bubbles to form at frequencies of 110, 890, 550 kHz also. This formation of these bubbles is accompanied by a hissing sound from the transducer.

The nebulizer can also distort the surface of the water, by causeing a portion to well up. In the Top photo, the power is off. The bottom is with the power on. Notice the 'wave' that appreas above the surface of the water. (It will stay in that same location and shape until the power is turned off.) At the peak of the wave, some fog/smoke is produced at the instace the power is turned on.

Ok, here is the ultrasonic mic Top, and it producing bubbles (bottom) The resonance frequency is about 2.5 MHz.. The Mics main resonant frequency is at about 22 kHz.. At this frequency the mic becomes active and starts to move around. After running this unit under water for extended periods of time I found that the wire contacts will start to fall off.. Next thing I will try, is to use the mics outside the container.. in an attempt to produce Sonoluminescence.
