Liquid oxygen equipment for glider

I take it the capability to fill portable containers is the motivation
for using lox, as opposed to using a concentrator?

The motivation for using lox is that oxygen systems can be much smaller and
lighter because the oxygen is in its most dense form and no high pressure tanks
are needed. This is why they are so popular for medical uses. A patient can
sling a LOX flask over a shoulder and go out for virtually all day; the same
mission with high pressure tanks would take an oxygen cart.

People might be interested in the British Summit Oxygen systems,
originally designed for HA climbing - http://www.summitoxygen.com/index.php
. It uses a cannula instead of a face mask and an electronic pulse-
dose meter system, which can supply up to 22 hours of oxygen from one
bottle.

This is not a LOX system, the concept is appears to be much the same as
that used in EDS systems...

Has someone ever implemented a liquid oxygen system inside a glider?

The USAF Soar Eagle project in the early 80s IIRC used a LOX system in
their G103. Jim Payne could tell you all about it I suspect. I have
a copy of his Project Soar Eagle thesis document which details the
systems on this wave ship.

I don't think the Flight Level 500 project of the same time period had
a LOX system.

For entertainment value...
Since Soaring Magazine refused to print the photo when it was
submitted, we need Mark Grubb to dig up and post the fantastic photo
of him (as towpilot for the day) standing in front of that G103, dead
ground squirrel in his hand (he had just run over it with a Pawnee)
while two USAF TPS pilots in pressure suits sit in the glider. A
bizarre sight. Looks like a futuristic Blackadder episode.
"Today, our in-flight meal is squirrel. Would you like it sauteed, or
fricaseed?"
It was always fun to watch the moon men come out of the Urban
Assault Vehicle, carrying porta-packs which they're hooked to until
they climb into the glider.
There's also a humorous to some, not to the pilot story from that
same project of what happens if you put those "scrunch them up and
they get warm" packets inside the boots of your space suit, which
amazingly has an atmosphere high in Oxygen. If the squirrel was in
that space suit, it would have been nicely sauteed.

Believe the DG500 "Perlan" prototype has a more modern LOX
installation. Einar would know more on that one.

One step at a time, buddy. First we get the LOX tanks on-board, then
we add the kerosene . . .

You have that already. It is mixed with the glass and carbon fibre.
