[PSUBS-MAILIST] just more calc

Hi Roberto,
It sounds like you are interested in using your sub more than actually building your sub.  Perhaps you should consider buying a K250, I am sure it will be cheaper in the end.

 Good morning this weekend i
 read the book on the psubs website as i can read ,is a
 collection of designs and experiences, i am working with the
 air volume and CO2 production, this because i divide the
 project in 3 main areas, pressure hull-life support-control
 & propultion
 learn that i can be safe on a composite hull, even a
 wood hull below the 100 ft i can dive even on an oil drum ,
 the  main concern will be O2 depletion and CO2 pollution we
 exhale 1.7 cubic feet hour  and by coincidence we need 1.7
 cubic meters per day
 will use this info for a better internal space before
 any other consideration, yesterday i went to a LPG truck
 scrap yard, found that the inside of the tanks are free of
 rust, they have  wave brakers ( internal plates ) have
 inspection holes with 2 inch tempered glass and  build from
 0.500 inch plate, 54 inch in diameter and 12 feet lengh,  
 
 may be other option
