<DIV>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<BR></DIV>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 <BR><BR></DIV>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<BR></DIV>( 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 <BR>
<DIV>
<DIV>i attach a picture if my concept and calc ( float level,volumen,weight
and pressure at 50 meters) <BR></DIV>
<DIV>may be some one build this before, will design to 250 feet to be safe at
150,<BR></DIV></DIV></DIV><BR><BR>_______________________________________________<BR>Personal_Submersibles
