[PSUBS-MAILIST] inexpensive buoyancy

[hank pronk via Personal_Submersibles]

 Brian, I am not sure what the tanks can take for external pressure, although I am sure it is significant.  I will maintain internal pressure above ambient and use the surplus air for operating MBT'sHank

 It would be nice to test one of those for outside pressure,  that's great idea for buoyancy.  BTW, sorry about the erroneous information on Ocean Gate - a text auto correct gone a rye!

Hi all,  I bought two 3,600 psi carbon fibre CNG tanks yesterday that are certified until 2032  to provide buoyancy for E3000.   I am encouraged by the use of carbon fibre in Ocean Gates new sub.  I bought them on Ebay of coarse, so I saved thousands of dollars.  I am getting 1260 lbs NET buoyancy for 1,90 dollars per lb  This increased amount of buoyancy will allow me to make E3000 a two person sub.  The added benefit will be increased stability and improved transitioning from surfaced to submerged.  The original added buoyancy requirement was 550 lbs, so you can see the benefits to having 1260 lbs to work with.Hank_______________________________________________Personal_Submersibles mailing listPersonal_Submersibles at psubs.orghttp://www.psubs.org/mailman/listinfo.cgi/personal_submersibles_______________________________________________
