At this time, I’m working with two theories.
1. The H and O atoms are still in the water molecule form but the water molecule has been encouraged to soak up electricity like a sponge soaks up water. The electrically charged water molecule then turns into an electrically expanded gaseous (explosive) form of water that is not steam.
2. The H and O atoms are split from the water molecule and prevented from recombining into H2 and O2 because they entered a ‘gaseous structure’ which Yull Brown called a “gaseous crystal’, George Wiseman called ‘electrically expanded water’ and Professor Santilli calls ‘magnecules’.
The actual fact may be a combination of these two theories.
