In the same general vein, please see the following link:
http://en.wikipedia.org/wiki/John_Kanzius#Water-related_discovery
John Kanzius is an Amateur Radio Operator that has demonstrated the
ability
to dissociate salt water into Hydrogen and Oxygen using RF. He is also
involved in a fascinating RF-based cancer-fighting technique that might be
described as "nano-based targeted diathermy." OT but very promising and
very interesting.
