I could see this working like an ice pack, where ammonium nitrite mixes with
water. Maybe the heat evaporates the water to steam so it can travel a path to
the ammonium nitrite, starting the endothermic chemical reaction. Very
interesting food for thought ...

I'm really curious on how this works. I keep thinking it's April 1st.

I remember when I first started caving and listening to stories told by Harry
and Charles and wishing some day to grow up to have stories like theirs.
Please pass along my deepest condolences to Harry’s family and the awe which I
held him in.

I believe there are a number of other texas cavers that would like to know this

Hello,
Those of us in GHG that have been around a while remember Harry Walker. I'm
sorry to say that Harry passed away suddenly, yesterday after a long battle
with Alzheimer.
David Locklear informed me that there will be a service for Harry at the
Crowder Funeral Home in Dickenson TX at 2pm this Saturday.
Crowder Funeral Home 851 Hwy. 517 @ 646 Dickinson, TX 77539. Phone:(281)
337-1515.
I called to confirm this. This is a link to their site:
http://www.crowderf uneralhome. com/default. htm
Harry hiked many of the 14ers and had always been and avid outdoorsman. He
went with us into Honey Creek to look around when he was 80 years old. He
was also one of the founding members of GHG.
His wife, Dorothy survives him. Many of us remember the parties at Harry and
Dorothy’s. We
enjoyed their pool and wonderful hospitality. Harry will be
missed and I can only hope that I have ½ his energy when I’m in my 80s. He
was a real inspiration to enjoying life for as long as you can.

You'd do well, Matt, to just keep on considering every day to be
April Fools Day. There's a whole herd of folks out there who'd have
you believe all sorts of hocus pocus. Natural science, however, will
provide the answer and the solution to the problem.
Gas refrigerators have been around for a long time. We had one that
used natural gas in our rent house when I was a kid. I have one in my
shed now; it came out of a travel trailer and used propane.
The principle of refrigeration (except on days like today when you
just leave the door open) is that when a gas under high pressure
escapes through a nozzle to a lower pressure it cools down in the
process. Your home refrigerator uses an electric compressor to
mechanically compress the gas (used to be freon, now is something
else). The gas refrigerator uses a small flame (about the size of a
candle flame) to heat its gas (traditionally ammonia because it has a
lower boiling point, but now could be some other high tech gas ???).
In both systems the gas is expelled through a fine orifice into the
cooling coils located within the freezer compartment. As the gas
expands it cools down considerably--sufficient to freeze water.
The thermos-sized thingy shown suspended over the camp fire is
probably some variation on that same gas refrigeration theme. There
is likely a gas filled cylinder in the bottom that is heated by the
fire and that HP gas is forced through a nozzle into the LP coils
surrounding the upper chamber--or a probe or something similar.
A few years ago there were several (European?) beer companies that
had cans which would cool a warm beer in a few seconds whenever the
top was popped and the pressure released. They had a captive,
pre-pressurized cylinder with a valve of some sort that was triggered
when the initial pressure in the can was reduced. Or something along
those lines.
Ain't science grand?

But most likely likely it's what someone else said - the Einstein refrigerator,
a single-pressure absorption refrigerator.

Just like anything else, energy is required to run it. Heat is energy so it
makes sense.

I will let someone who knew Harry back in his heyday describe him.
I met Harry in 1989 at a Houston Grotto Meeting. He appeared to be in his
late sixties, but he showed slide shows of recent caving trips to the
Sierra Madres. I
was very impressed with his slideshows and his enthusiasm. He was always
inviting me to go on his trips, and I always had to turn him down,
because I couldn't
get off school or work, or it conflicted with going to the NSS Convention.
Harry and I did got to TCR a few times together, the last being the big flood at
Chalk Bluff. And I tried my best to get him to go with me to the
TCR, just a few weeks ago.
In 1998, Harry invited me on what would be his last attempt to complete all the
14'ers in Colorado. But he planned the trip during the Tennessee
NSS Convention,
which I was greatly looking forward to. I had to make a tough
call, as I knew
Harry was 70 something, and I would never again get the privilege of climbing
with him. We tried Mt. Anterra, Greys Peak and Torrey's Peak.
Harry would
have made it to the top had he been with an experienced person, but I had never
been mountain climbing and I was way too out of shape. We later went rafting
thru Brown's Canyon on the Arkansas River near Salado, Colorado.
http://www.atraft.com/8-8-03%2017%20C3_small2.jpg
Harry was flipped out at Snider's Suckhole and we thought he may have drowned.
It was a very tense moment waiting for someone to find him and pull
him out of the
eddy like water.
Harry apparently started caving in the 1940's, back east somewhere. He had
a low NSS number. I saw him climb rope at a vertical practice
about 10 years
ago, and he did fine. I think he has been into Purificacion.
I know he climbed
Pico Candela, and that inspired me to give it a try.
Harry's claim to fame is that he taught his nephew how to cave. His nephew
moved to Arizona, and went caving with some other guy and found a little hole
that they kept secret for many years called "Kartchner Caverns." I
recall Harry
talking excited about it back around 1991 or so. He also showed me
the recent
book, before I had seen it at the NSS Convention.
Harry became an important role model in my life and I looked to him for wisdom.
He more than anybody else, was the caver that advised me to marry my current
wife. Had he told me to run for the hills instead, I probably would
have. And
since I have an incredibly wonderful daughter, I can only tell Harry
"thank you."
Harry based this judgement on at least 2 road-trips from Houston with
my then-girlfriend. One
to Carta Valley to go in a cave, and the other to at least one TCR ( 2000 ? ) at
Flat Creek Ranch.
Hurricane Ike was a stressful event for the Walkers. I think it
really took a toll
on Harry. However, what really may have done him in was that he lost a
whole lot of money in his retirement account these past few months. It was
only about 4 weeks ago, that he and I sat down at his dinner table and he told
me with almost teary eyes that he lost a great deal of money. I can
only guess
that means 100,000 or more. But he was too upset to talk about it. The
tone of his voice was from someone who was wiped out, not the Harry I had known
for 19 years.
I have been out of work for a few months, and Harry paid me to work in his yard
to clean up the debris left over by Hurricane Ike. It was a real mess and he
really needed someone with big chainsaws and a bobcat with claws on the front
of it. Anyways, I am thankful for him paying me, as it was a big help at this
time.
My daughter met Harry a few times. She temporarily had a pet turtle. We
named it Harry.
Harry always wanted to go to Houston Grotto meetings but it was a very difficult
drive for him from Dickinson. For a while, another caver, Ray
Hertel, was kind
enough to bring him to the meetings. I guess it has been 5 years since he
was able to attend one, so none of the new cavers know him.
I think Harry spent most of his working life for a company called Monsato. He
may have been a chemical engineer, but I don't remember.
Again, I will let someone who knew more about him, tell Harry's story.

Hi David,
I've only met you at TCR this past year, (tuna fish sandwich), but I've been
reading your posts (not the LED ones) for the past few years and think you are
a very interesting person. I love that you take such an interest in the caving
community and yet claim to be an armchair caver. I also admire that you took
such an interest in Harry Walker. Until this last post of yours, I hadn't
realized that you had known him from the past. I thought your IKE help was from
knowing his previous caver status, not that you'd met and spent time with him
in the past. Kudos to you! I'm sad to hear of his passing, but glad that you
were there at the end to help with his hurricane dilema. You know he felt
comfort and relief from your presence in that horrible time. Good luck in your
job hunt and don't forget that you will be blessed for your kind
deeds...eventually. (Life is tough, and then you die) A saying I remember from
the 80's but not sure of actuallity!
Cheers,
Jenny Holt
(Not to be confused with my REPUBLICAN father, Fritz)
