Rich people have the coolest toys. On display today is the Triton 6600/2, a personal submarine that’s being billed as “the world’s deepest diving acrylic hulled submarine”. Its diving depth is reflected in its name, as it’s able to get all the way down to 6,600 feet. It does so slowly, topping out at 3 knots (3.45 mph or 5.56 km/h), but the long dive down shouldn’t have you stressed out since the battery will provide enough power for up to 10 hours, with enough air for up to 12. There’s even a reserve 96 hour tank of oxygen so you really don’t freak out. The clear hull is the thickest ever, yet is said to be “optically perfect”, which is good since looking around is all you’ll be able to do in this sub; there are no robotic arms to grab stuff down there. And of course, it’s dark in the depths of the ocean, so six 20,000 lumen lights are present to help light up your surroundings. So yeah, if you’re tired of roaming the dry soil on your private jet, you can now give yourself the luxury of exploring the oceans in style. You will, of course, have to pay a cool $5.5M for the privilege.
