Paramagnetic oxygen and new rebreather ideas

teomannaskali

I warn you that i am full of very stupid ideas and I am known to try to apply new thins I learn to thing I try to develop (usually they dont go any further that mental masturbation, still, I prefer it to watching TV)

Hese is something probably veeeery veery stupid. But if it is not it might change a lot....

I was researching about oxgen and and foud a site about its paramagnetic properties.


O2 has paramagnetic properties
http://chemmovies.unl.edu/chemistry/...mos/BD005.html

the link contains a video of a bubble of oxygen being pulled around by a magnet.

If we were to add magnets somewhere in the rebreather then we could help retain the oxygen. I dont remeber much from chemistry lessons, but if kept inside the scrubber then we could maby make the CO2 molecules stay longer in the scrubber.

Obviously this would have not been developped in the military for obvious reasos.

Maby even have a whole bunch of magnets in front of the compressor to get nitrox... Probably you would get 21% instead of 20.9%.


Just to get you thinking...

This place sells Magnets From Hell...scroll down to the "Supermagnets" section.

Get a few and play around! Take some weight off your belt! Crush your fingers and possibly break your arm! Fun for the whole family!

They have some really strong ones inside HardDisks...

Yes O2 is paramagnetic but CO2 is not. So having superpowerful magnets in the scrubber would probably not do anything to the dwelltime of the CO2 in the scrubber.

As a sidenote the magnetic properties of O2 is used in paramagnetic O2-sensors. We have one by our fillstation. The advantage of this sensor is that it last basically forever and does not age like a standard fuel cell sensor.
The disadvantage is that they cost a lot more to buy than a normal sensor.

And unfortunately they tend to be sensitive to vibration and motion while measuring. So they are not suited to be used inside a rebreather...

Sadly the Magnetic Susceptibility of Oxygen gas is 0.19 and that of Aluminium is 2.2 so when you have a magnet sufficuently powerful to pick up pieces of aliminium we can start on oxygen.

Paramagnatism is an awfuly marginal force.
