Since you can’t actually fly the Enterprise through space, this is the next best thing. A submarine version of the Enterprise that can explore the deepest depths of your swimming pool, by Japanese model maker Starfleet Yokosuka.

It’s a 1/350 scale model. Of course all of the life that you encounter will be marine life, but at least you won’t run into any Klingons. Don’t worry, Kirk can still find a mermaid or two to shag.

This one is for geeks who find themselves in the bath tub with no toys to play with. This Submarine won’t hold nuclear missiles and it won’t propel itself underwater, but the waterproof submarine- K-95 USB flash drive is waterproof like the real thing and will hold 1GB or 2GB of storage.

You could pretend that the data inside is sensitive and that it is being chased by another sub who wants to steal your secrets. You can choose from green, white, red and black colors. Bath time just became more fun.

Okay, so it looks more like a dark mustard. The C-Quester 2 and C-Quester 3 submersibles from U-Boat Worx are like a Smart Car for the ocean. They’ll be shown at the Monaco Yacht Show 2008. The two-person C-Quester 2 is designed to be a new toy for megayachts. In other words a plaything for the filthy rich. The three-person C-Quester 3 can be used by seaside hotels and resorts so guests can have some fun.

Each features a safety buoy, air conditioning, underwater communication, altimeter, sonar, and optional video cameras and tracking systems. The electric C-Questers can even dive up to a depth of 100 meters and they run on a Lithium-Ion battery. The first C-Quester 3 will be available at the end of this year with more scheduled for next spring. Unfortunately drivers have to be trained as a submersible pilot before using. And since there’s no four seater, you won’t see the Beatles while you’re out and about, but maybe a Blue Meanie or two.

Check out this submarine that looks like a dolphin. It’s called the Innespace Seabreacher, a two-seater submersible that looks and moves like a dolphin. Interestingly, the Seabreacher uses the same canopy as an F-22 fighter jet to insure that the inside stays nice and dry with a watertight seal. The vehicle seems a lot like a jet fighter for the water when you see it in motion.

Since it’s made to mimic a dolphins movement, it uses the downward lift of the wings to jump out of the water, and even do barrel rolls. I suppose it’s as close as humans can get to actually being a dolphin. You have to wonder what the dolphins think about all this. Check out a video below.

The Cerva MC08 is an oval-shaped concept transport vehicle that almost looks like it sports an evil laughing face in front. It’s designed for use as a car, motorcycle, a jet plane and even a submarine. It was designed by a team of designers including Michal Cerva, Jiri Bicik, Jana Kunstova, Marketa Schindlerova, and Jan Zof.

Of course, it’s in the conceptual stage, but you have to admire their ambition. The Cerva MC08 is somewhat modular and can be fitted with a variety of extensions: three wheel axles can be fixed to use it on road. It can carry either one or two people at a time. On the road, it’s middle wheel slips forward for stability at higher speeds. In slow speed the stability is established by gyroscopes hidden in the axle. This is a perfect toy for those rich adventurers out there.
