Hello. It sounds like the phenomenon you are referring to is "sonoluminescence". As you may already know, this is where light is produced when a bubble in water (and possibly some other liquids) is subjected to large amplitude sound waves in the water. You're not really "producing energy from water using sound", but rather converting the energy in the sound to light energy emitted from the bubble, via some mechanism which isn't really understood. A nice article for building your own sonoluminescence device is found at http://www.physics.ucla.edu/~hiller/sl/makingSL.html Some other references (web and otherwise) are http://www.sciam.com/askexpert/physics/physics3.html http://www.physics.ucla.edu/faculty/ladder/putterman.html http://www.physics.ucla.edu/~hiller/sl/ Scientific American, February 1995 I wouldn't count on getting any heavy water. My impression is that access to reasonable amounts of heavy water is controlled, due to its possible use in nuclear weapons development. But I could be wrong; maybe the MadSci administrator or someone else could better address this question.
