Hi, Roberto,
 
Thanks for the introduction and the info on your sub design.  Here is  a 
link to a site you might find interesting on different subs.

Hi, thanks for the info,  i live on the baja california peninsula,  on the 
sea of cortez side, here the black market of the swim bladder of the  
totoaba mcdonaldi  an endangered fish is devasting the  population

this fish live at the 50 or more meters as grouper but  also migrates on 
groups, each pound is valued ay 300 dlls aprox,  the  panguero just remove the 
bladder from the female, , add some weight and send  it to the bottom,  i 
will use the submersible to document this as will be  safer stay at 50 meter 
on a sub than on scuba 


My concep is a  powered capsule, now on an egg made with 3/16 A36, one 
outer shell and 1 inner  shell, will have 8 reinforcement rings at 6 inch

( 36 in diameter and  45 inch between bulk heads, hemispherical or 
cilindrical shells ( based on  what is cheaper ) i calculate 400 pound of lead, so 
will add concrete on the  center area to reduce lead and make ir more stable 
as will travel or dive  vertical, based on the acrylic viewport design i 
calculate 24 inch in diameter  and 1/2 inch inch tick for the 150 feet range, 
at first will made a solid top  shell with an small viewport for install a 
camera and have the info on  screen,also will install imaging sonar 
transducers for the external 

i attach a picture if my concept and calc ( float level,volumen,weight  and 
pressure at 50 meters) 

may be some one build this before, will design to 250 feet to be safe at  
150,
