[PSUBS-MAILIST] inexpensive buoyancy

[Alan via Personal_Submersibles]

Hank,
will they be well protected against collision?
From memory G.L. don't want you to have any external pods that can
cause a catastrophic situation if they fail. I.e. if your battery pod fails
you should have a large enough drop weight to counter it.
Did you consider going for a number of smaller cylinders, as 600lb
flotation is a lot to counter if one was ruptured.
Cheers Alan

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.
