The method of using sound to transmitt information underwater is allready in use. It was developed studing the way dolphins comunicate. The system works with impulses on 40 - 80 Kiloherzt and you can transmitt up to 36 Kilobits per second. The range is about 2 km (1,5 miles) The sistem was developed to be used for the transmision of information fbetween the tsunami bouys with the deep sea sensors.
For more information you can look at
www.evologics.de
There are also some other ideas for submarines and propelers.
Best wishes
Jürgen
