There are two versions of the vessel available, a one-seater and a two-seater for those who wish to take on a passenger. The maximum speed is only about 3.5 mph, but this isn't about speed, it's about inexpensive personal underwater transportation. With three-quarters of the earth covered in water, perhaps we should give this idea some serious thought? With the recent inventions of solar powered boats, how cool would it be to attach one of these to a solar boat and be able to have your own underwater adventures with very little impact on the environment? Plus, you could be almost self-sufficient; you would never need to come ashore to refuel your vessel - water for yourself, on the other hand is a bit of an issue, isn't it?
Back to reality - is this really practical? Not really, unless you live in an area like Venice where you could actually get around in a watercraft. But it's cool nonetheless!
