Alan,I have found that gasoline is the the lightest practical choice.  I would however opt for diesel even though it is not as light  but much safer.Hank

 Hank, have you looked at oil for buoyancy.That syntactic foam for deep submergence is probably not thatlight with it's microscopic spheres. On Alvin they told me the foam& the testing of it was about $3 million. Alan

Hi Hugh,Thanks' I wish sometimes I spent more time thinking LOL  I am looking for a way to go deeper without the crazy cost for buoyancy, I am looking at different materials for a pressure hull as well as for buoyancy.Just fun stuff to think about.Hank

Subject: [PSUBS-MAILIST] head strength Hi Sean,I have been studying the head maximum pressure chart on Psubs and found that the pressure rating increases the same amount proportionately with thickness.Is there a limit to this?  Thank youHank  _______________________________________________
