@washnon: Nothing is going to happen in 2012 except a lot of people running around like headless chickens for a few hours and then having a good laugh the next day, denying that they believed anything was going to happen. So go buy one of these subs. ;o)
i want to know how you control the bouyancy so effectively??? when i try experiments with a bottle (dont laugh)filling it with water to achieve neutral bouyancy it either floats or sinks- it must very be very precise how much air you blow to control static dives? any more footage I might be interested in the plans...
To get the buoyancy right, you flood a tank until the moment the apex of the dome is touching the surface. Although in the video I purposely overdo it to sink faster and then just blow a little ballast on the bottom. Plans are available on the psubs website.
Yes, it's a Kittredge K-250. The main hull cylinder is 0.25" thick, though in some areas like the juncture of coning tower and main cylinder it's a lot thicker. The steel is rolled from flat plate.
Now this made me scarred when you almost munched the big brick! How safe is it? How far is visibility? (5ft?) ... that cable, was it a power line or something? How would you compare lake diving to ocean water? ... must, have, more... videos :)
What was the thing you hit?
