Thanks Christina.
Firstly we are interested in wether Tao's design
is ambient (presurized from the inside with compressed air so the
inside air pressure is equal to the outside water
pressure at any depth), or 1 atmosphere (normal submarine where
the strength of the hull resists the outside
water pressure).
If as we suspect, it is t he 1 atmosphere; how
thick is the metal the barrels are made of & what dimentions are
they?
Does he have reinforcing rings inside
them?
I have seen a quote of 33ft as Tao's maximum dive
depth, this could be way too deep for the barrels.
With submarines there is a design crush depth,
the depth at wich by calculation the submarine should crush.
The test depth at wich the submarine has been
tested to UNMANNED.
Then the maximum operating depth wich is 1/2 of
the unmanned tested depth.
The operating depth could be 1/4 of the
submarines estimated crush depth.
At 33 ft deep there is 2,116 pounds of
pressure on every square foot of the submarine.
Should the submarine colapse with Tao in it, does
he know that if he escapes at depth he will have compressed air
in
his lungs & needs to breath out as he ascends
to avoid his lungs bursting & possible death.
Does Tao have any questions? We would be happy to
answer them for him.
We are very impressed, its a difficult task
building a submarine.
If you look on the psub site under members
projects there are a lot of pictures of submarines in progress.

You all are really professional! "Would be
fantastic to have your advices" Tao told me.
Tao can not speak English, and I will translate for
him :)
Here's the picture story:
And, we will have Reuters TV story and Retuers
Text story tomorrow, a multimedia story as well.
Will send you the story links when ready on
the wire.
Best Regards,
Christina.

Alan, thanks a lot for this as that was a big concern I had when
I met him. I copy Christina Hu into this e-mail as she is in contact with
him at the moment and she will help to make contacts. Tks and brds Reinhard
