In this set up we have a quartz container holding a column of water
which is being vibrated by a transducer attached to container.
The transducer is driven at a frequency that produces a standing wave
in the column. According to the file a 700W amplifier was driving the
transducer and sufficient energy being passed to the water to cause
evaporation. The speed of evaporation was such that the frequency
applied had to be varied in order to maintain the standing wave.
A some point in the experement the water vanished leaving a hole in
the roof above the container.
It is suggested that the water disociated when the frequency hit one
of the Keely frequencies. This may well be the case however I think
the following explaination fits the facts equally well.
The water is being heated as evidensed by the evaporation. I am
assuming that the inside of the container was smooth so when the
water reached boiling point there was nowhere for the first steam
bubble to form. Under these conditions it is possible to super-heat
water that is to raise it to a temperature above 100C without is
actually boiling. A super-heated liquid is very unstable and actual
boiling can be triggered by a shock or physical contact with
something that allows vapour bubbles to form. I suggest that this is
what happened to Dr. X, his column of water was super-heated and
vanished through the roof in a steam explosion when boiling
was finally triggered leaving a hot dry container behind.
Have I missed anything? Comments please.

PS You can demonstrate a steam explosion easily in your workshop.
Simply clamp a spoon's handle in a vice so that the spoon could hold
water. Next turn a blow lamp (torch) on the dry spoon, no need to
heat it red hot, it just needs to be over 100C. Next put a drop of
water in the spoon with an eye dropper. The drop will dance around the
spoon on a cussion of steam, while this is happening the drop is
being heated by the steam suddenly there will be a bang and the drop
will disappear this is a steam explosion, you will feel a mist of
water on your skin as the seam recondenses.
