When submarine maker Graham Hawkes started designing his next generation of underwater cruisers, he decided to look to the skies instead of the sea.
Hawkes, who built the "Mantis" sub for the James Bond film "For Your Eyes Only," was attending a drone conference a couple years ago and attendees were discussing the goal of one day constructing a manned drone.
"I thought, 'Well I can make that work underwater, and that'll be so cool,'" he told CNBC's "Secret Lives of the Super Rich."
"The principles are very similar to a sub. It's just in the water instead of the sky."
Thus, the DeepFlight Dragon was born. Part Formula One car, part drone and part submarine, the Dragon is a personal submarine that's designed so that anyone can drive it after some quick training. The Dragon has four thrusters (which look like drone propellers) in the hull that pivot, allowing them to power the sub up, down, forward or back.
Unlike most subs the Dragon is positively buoyant, so it floats to the surface when the thrusters stop — a big safety advantage compared to traditional subs. It seats two. And the big spoiler in the back not only provides downforce when it's moving, but a sleek, race-car look.
