The Hyper-Sub boat/submarine hybrid was built by a Florida man and his neighbor. It's capable of cruising the sea at 40 knots (~46 MPH), and then dive to depths of 250 feet. It has a 500 mile surface range and currently only exists in prototype form. However the man responsible for the thing has started a company and hopes to get models in production in the not-too-distant future. Which would be sweet, because I've always wanted a boat-sub hybrid. Almost as bad as I've always wanted a time machine-rocketship hybrid. But I actually built one of those last year so I'm good on that. As a matter of fact, I'm actually writing this right now from the moon while I bang Cleopatra. True story, I have the laptop resting on her back.
A bunch more pictures and a video after the jump.
