Regardless of what one may think of his movies; this is bad ass.
I am surprised that there is not a fleet of autonomous subs roving the ocean floor and mapping it which belong to Google.
Or any other body for that matter.
Seems like it would be a good idea to make small, unmanned subs that "roomba" the ocean floor collecting data, mapping and taking video and pics.
They should surface whenever their batteries run low, solar re-charge and upload their data.
His website is pretty cool too.
