[PSUBS-MAILIST] Reserve buoyancy

["F. Marc de Piolenc" <piolenc@archivale.com>]

Correction to my earlier post. Aluminaut had silver-zinc batteries, 
which have an alkaline electrolyte. There was no danger of chlorine gas 
generation - only hydrogen!

Best,
Marc


Battery vented into the crew space? No means of airing the boat without
leaving the hatch open? I can understand not providing a separate
snorkel or air-induction trunk - this is a deep diver, and every
pressure-hull penetration is a potential failure point - but in that
case the saddle tanks should have been made larger and some means of
fitting a funnel over the main hatch to prevent water ingress should
have been provided. And as for venting the battery into the crew
compartment, ANY arrangement is preferable to one that exposes the crew
to hydrogen, or worse - chlorine!
