      When I was 8 or so I had this great idea to build a submarine out of oil drums. I obsessed over it and spent Way more time than is healthy drawing up plans in coloured pencils... A cute little stick figure inside two oil-drums welded together and two little drums on the side of it which were ballast tanks. It even had a modified toster underneath it to work as a steam jet (like the one on slashdot a couple of weeks ago but wouldn't have worked, however it was Australian designed).

      I can't help thinking that if I was one of those "active kids" you know the ones... the ones that leave the house more than just to go to primary school, I would have either electrocuted myself with a toaster or drowned....

      Buoyancy is the problem. You need to carry enough weight onboard to submerge. But this means you're not going to just float back up without a means to float again (usually compressed air). If anything happens to that system, then you go down like a rock.

      Submarines will normally have atleast 3 or 4 ways of surfacing. Primary and secondary main balast tanks, either of which could surface the submarine alone, variable balast tank (sometimes using a pump rather than compressed air) and a lead drop weight which can be drop via a lever from inside the sub. They are normally two seperate high pressure air systems as well.

      Actually, the way the subs work (most modern anyway) is that they pump WATER into the air tanks, compressing the air and creatting a pressure (and making the tank HEAVIER). When they want to surface they let the air PUSH the water out. If you sub is well designed you only need to OPEN the drain to let the water be pushed out. Most subs DO have compressors to add more air pressure (and there for empty the tanks faster and more completly) however they can surface with out these (in the case of a major power failure). Whenyou were to compress the air in your tanks you don't change your boyency (because the air comes from somewhere so your totall MASS is the same. They way you change your bouency is to ADD something (usually the most avaliable thing is water). Also most modern subs have a way to drop excess weight, like propellors and engine parts via explosive bolts (again for emergency procedures). I'm sorry, i hate to inject some REAL knowledge about subs.

      Actually in 688-class and EVERY OTHER SUB I HAVE EVER SEEN, The water is simply allowed in by letting air out through a valve on the topside of the ballast tank. there is an open hole on the bottom side to allow the water in while you bubble the air out. That is also why subs don't do well inverted. If you invert a sub (difficult with ballast and batteries on the bottom), it will never surface again. Can't get the air to stay in ballast that way. I've never heard of your system. Oh, and you can't just dump your screw- that would leave an 18-inch hole in the hull where the propshaft bearing is situated. It just so happens one or more subs sank while in reverse thrust. a retainer of some sort failed and the prop pulled itself out of the boat. Bad. What is your experience with submarines?

    I agree with most of what you say, but you seem to imply that I am wrong about the bail out h.p. air. In subs you always need more than one way of doing things, and if you are a safe subman, you will have bail out air on your boat.

    Read The American Bureau of Shipping's: Rules for building and classiing underwater vehicles, systems and hyperbaric facilities. OR Busby's Manned Submersibles for more information.

    To pressurize a sub to match water pressure with air would be extremely dangerous if done in a hurry and the air would become poisonous; to breathe under pressure at depth (Deephabs) you have to be slowly pressurised with exotic gases. Note that regular submarines only increase pressure a little when submerged.

    There is no way you are going to beable to open the hatch if the outside pressure is greater than the internal pressure. Flooding the sub is diffinately an option, but depending on the sub, this can take time (most people put large enough bailout valves to do this in a reasonable amount of time), also if you sub is damaged or disabled you might not beable to flood it. Even with the sub flooded, you still want a small bubble of air to work in while you release the hatch (although you can use scuba gear, but the bends might be more of an issue).

    Some psubs allow you to flood them so you can go for a swim and then return.

    Immediately you let go of the sub you find yourself ascending at an incredible rate, gas rushing from your mouth, nose ears and eye sockets and your lungs searing. Finally you arrive at the surface travelling at such a rate that you are thrown several feet in the air. Somehow your lungs/arteries didn't rupture during the ascent but you now die in 20-30seconds from the massive nitrogen boil-off in your veins as you suffer from an incredible case of 'bends'

    Yell all the way up. The bends won't normally be a problem since you are not spending enough time under pressure to become saturated (of course, if you had to spend a lot of time trapped in you sub while under pressure this would be an issue).

    No two ways about it, submarines are still extremely dangerous.

    Hehe, agreed, but everything is dangerous if you are stupid enough.
