Pressure is the sum of all the atoms/molecules squeezing an object. Being
able to alter one atoms force changes the sum pressure. Or am I wrong and
pressure is independent of a single atoms force vector and has something to
do with the field between atoms/molecules ?
The atom scale versus
the object scale is confusing.
Imagine a room packed with people. More people are coming in. In the room
is a
circle of people all being pushed at the centre of the circle. The circle can't
get
smaller because people of the circle jam on each other. A person inside the
circle has space and will never feel any pressure.
Could a, yet to be designed, nano spike system generate reversed menisci to
block pressure transfer?

This sounds like it would be interesting if I knew what it was all about. |

Are you saying that the water molecules ought to
pack together and act as a "shell" to protect
whatever's inside them? |
|
| |
What I am desperately trying to get my head around is the truth that actions of all those tiny atoms and molecules sum up to give the overview maths of pounds per square inch. If each of those force vectors, say 5 atoms thick, can be manipulated then the summing up would be affected. |
|
| |
Ultimately the 'shell' has to be at more pressure/stronger than the outside but how this is done is totally wide open. |
|
| |
I suspect that this isn't possible, but I would love to
be proven wrong. I like the thinking behind it. |
|
| |
Perhaps I'm confusing my forces here, but this kind of make me think of frictionless. |
|
| |
If you could monkey about with the pressure applied to the hull, then that could be a bit of a bugger, as the sub might plunge to the bottom of the sea. |
|
| |
I imagine buoyancy would be not affected because the surrounding ocean would take the 5 atom* pressure transition layer as part of the vessel.
A very large safety cable might be the go on the first manned test trips. |
|
| |
* Or how ever many layers of atoms to hide the vessels surface from a full pressure vectored atom/molecule. |
|
| |
How about the name pressure feathers rather the spines? |
|
| |
strangely this reminds me of the debate about storing pressurised gases in lightweight containers, bit like a matrioshka doll, but with skins instead of dolls. |
|
| |
The gas in centre skin is highly compressed, the layer outside is less compressed, and half of the expansionary force would be directed inwards towards the centre skin..... |
|
| |
Assuming you could get the pressurery blocky thingy working then it could store gases too. What's my percentage of the patent? |
|
| |
[bigsleep] didn't I mention that to control at such a high level is going to cost in manufacture and/or in the decay rate while in use. |
|
| |
[not_morrison_rm] I would have to apportion your percentage to directly reflect an atom's work in the overall reality of the situation. No seriously, you put the work in on the adaption, it yours. |
|
| |
Done. Bugger to get the sea-urchins to stay still.. |
|
| |
If a layer of sea ice could be persuaded to grow on the external
surface of a bathysphere then this could carry some portion of
the hydrostatic loads and thereby offload the vehicle structure.
In principle I suppose the ice could carry all the load. There are
many engineering problems to overcome but the idea of
creating a pressure vessel from the fluid itself is intriguing. |
|

[+] for getting me to think about this. |
