Re: [PSUBS-MAILIST] oxygen generators

["Richard Gordon" <lrrg@wantree.com.au>]

I realise that obtaining large quantities of radioactive material on the
black market as this gentleman obviously did, would attract a great deal of
attention from the police. What I propose is to utilize the same isotopes
that are used in many facets of medicine and also in house-hold
smoke-detectors to construct a device that would be no more harmful that
your kitchen microwave oven.

As for the VG hulls, what I had in mind was areas of very simple articulated
frame with a tough oil-impregnated neoprene skin stretched over it. This
would not risk a puncture, nor would it add an unacceptable amount of
weight. It would however only be suitable for small to medium sized manned
subs, maybe even better for an AUV. But I think Carsten is right, I should
stick to the magnetic engine!
