The SAUV II is the second generation Solar Autonomous Underwater Vehicles from the joint work of Falmouth Scientific, Inc., Autonomous Undersea Systems Institute and Technology Systems Inc. and some Navy involvement.
It is a pretty impressive craft. It says you can buy them from Falmouth Scientific...wonder what the cost would be? Looks expensive and hi-end.
It uses Slackware (score one for open source) and PC104 boards as brains. Wonder if there is a cheaper solution...might be pretty cheap already as far as brain power/cost goes.
The sensors and communications pieces are probably the most expensive bits. The price for some of the satellite GPS Argos-based trackers seems to be $2-5k....
