EDIG already failed to deliver a Nunchi and Microsignet prototype. After a year or so of shareholders waiting EDIG simply introduced a new wrinkle since no doubt they figured share holders were getting suspicious. So then EDIG talked about the Synap concept and I assume shareholders will wait another year for that prototype...maybe not though now you will be waiting for the water thingie prototype. Good luck with that!
Oh and watch out with your ideas for using sensors. It sounds like you would be infringing on the NUNCHIE patents which cover every use of a sensor over the internet that helps you make a decision. I will have to report you to by buddy Fred.
