Re: [PSUBS-MAILIST] Underwater tent...

[Warren Greenway <opensourcesub@yahoo.com>]

Pics? No, sorry, I just dropped the stuff off at the
waste transfer site...Moving, you know. The size of
the
protos I made was in the foot-by-foot range. I mostly
wanted to see what kind of a structure would be 
required to keep the thing from collapsing. The 
structure can be very flimsy indeed. I want to make a
full size proto after I move. I really can't forsee
any
problems other then the air supply. The support
structure will be simple fiberglass poles a central
tether cable will hold it down. It would look like a
pentagon from the top and a pentagon from the side.
The floor would be suspended above the water.
