James Bond’s Sub For Sale

OK so it's not really James Bond's submarine, but it sort reminds me of one. This is a personal submarine for either one or two really rich, possibly stupid geeks. This looks just like something the boys at Google would like to purchase to go with their giant private jet. What I'd like to know is what crazy person is going to risk death when the submarines batteries that only last for 2 1/2 hours per charge run out of juice. Maybe I can see their use in a place like the Caribbean where the water is not necessarily all that deep in some parts, but you can still see the reefs and such at a shallow depth. At least that way when you run out of charge in your sub sinks to the watery depths below perhaps you have a least some chance of making it to the surface. I see no prices mentioned for the submarines, which likely means they're so expensive if you have to ask, you can't afford it.
