I see you are quite educated and knowledgeable about water. Thank you for all of your contributions on this site, I find them very interesting.
In response to your post, the Stirwand™ was clinically proven in a 90 day, 100 subject study (completed in Dec. 07) to increase hydration by 28.5%. (http://www.quantumagewater.info/pdf/100subject-90day-study122007.pdf)
During the 2007 trial, the Stirwand™ technology raised the test water's coherent energy from 90 milliwatts up to 11,408 milliwatts, while dropping the kinetic energy from 238 millivolts to 136 millivolts after stirring the water for 20 seconds. This results in highly charged negative ions to scavenge free radicals (-102 ORP), along with noticeably increased mental and physical energy.
Personally, I don't find it alters the taste as much as the texture of water. While I do sell the Stirwands, I am here to educate people about these trials because I feel this is information that needs to be shared.
