2 The front ballast chambers fill first, sending the boat into a five-degree, 60-feet-per-minute dive.
3 Once underwater, the pilot deploys dive fins, angles them downward with a joystick, and engages the thrusters to dive faster.
4 To raise the boat, the pump system fills the chambers with 400 cubic feet of air from pressurized tanks, reseals the hull, and resurfaces in 30 seconds.

drug smugglers. This is one of those "good idea/bad idea" ideas.
James Bond wants several, I should think. You know, of course, that you could run this submarine on gravity alone and not use fuel at all, don't you? Just guide the sinking. No energy means no energy signature, too.
Coined "Inclusive" and "Inclusive Democracy" concepts from math term.
Original creator of "Lights On! Tampa!" art display/contest.
Proposed "Floating Riverwalk" for Tampa
Proposed Lee Roy Selmon Expressway extension to St. Pete w/rail link.
That's right! We shouldn't ever do anything cool or new because drug smugglers might use it!
The drug war is a crock. Legalize, tax, and regulate.
People will abuse it anyway. Look at prescription meds. Some geniuses even huff paint. You'll never stop people from doing what they want or trying to get intoxicated. You'd think the repeal of prohibition would have been a clue. Anyhow, I better stop. Some DEA agents have families to feed and doors to kick down in a paramilitary raid. All in the name of keeping you from harming yourself!
There already exists surface craft that can "fly" underwater using wings and rudders, without the problem of ballast considerations.
I'm impressed that this sub can dive to 1,200 feet, but unless it's constructed a lot better than it appears to be, with nice big picture windows, I doubt anyone would be alive in it when it got there.
LoL! ^_^ I'd still want one just to try it out! Too bad it can't fly too. =(
Oh well, since it reaches 45 mph ill just build a ramp and make it fly! xD
why? when there are so many other choices.......still land will be destroyed to get the coal , people die mining it, water is polluted from mining......land is taken from people to get at it.......wake up people!! we are smarter than this most things we truly need are above ground just a little blessing from the universe and god!!!!!! Why do we feel the need too waste time.lives and money tearing things apart to find our answers....the world was designed perfectly , we have the sun , wind & water to obtain energy we can create hydrogen gas from water and as an added bonus we keep the beautiful mountains to visit with our children. Why do we cling to our destructive ways when we have better cleaner answers- this bs spreads money too thin and holds back real progress- sooner or later there will be no coal for anyone this is already known why not pretend this is so now and move on to better things okk?
