Lithium Hydride would offer many times the lift/pound.  So would the
borohydride.  Since you have no objections to exothermic reactions, why
carry something as heavy as ferrosilicon and caustic soda?  The light metal
hydrides, under the right circumstances, can actually store more hydrogen
in a given volume than even a cryogenic liquid cylinder.
The DoE publication and a technology summary for one of these systems
can be found at: http://www.safehydrogen.com/technology.html
I am one of the authors and inventors. It was fun working on it.

Great reviews on Tucson!  I am glad I didn't go...

While checking out John Bailey's site, I notices something that I decided to
discuss with the community.  He has a piece of cut Pakistani Topaz listed at
$472/carat?  I have been in the rough business a long time, and know that
clean, peach colored Pak Topaz retails for $800/kilo in the 20-50 gram/per
piece range?  So how does a cutter justify charging so much for cut stones,
and do people really buy stones at this price?  Perhaps I need to cut more
than I sell in rough?

On another note, I have noticed that in the past several years there have
been a lot of "new" sellers putting up websites.  I think this is a great
idea.  However, several of the newer sites are blatant rip-offs from other
people's websites...people who have been around for a long time.  I won't
mention any names because my point is not to start a witch hunt or to offend
anyone.  My point is to educate.  However, theft of another person's web
content is a federal crime in the US.  I won't bore everyone with
Intellectual Property Law, but if anyone has any questions or comments, send
me an email.

Thanks,

John Thielmier

I have been using carpenters white glue for years for attaching small stones
for splitting or cutting in a 10 inch slab saw and an 18 inch Highland Park.
  Procedure --- Cut 2" x 2" clean 2x4 wood or other sizes.  Make sure wood
is dry and clean.  Apply glue to flat side of stone and press  -let dry for
a day or two--do the slabbing .  To remove material from wood , soak in
water untill they separate .  I have never had a failure   { seldom use the
word  failure}  .I began using this method years ago , using Elmers Glue ,
and found better results with carptnters glue from Builders Square.  Seems a
little cheaper than waterglass.  I have split several hundred "bisquits"
from Woodward and Walker ranches using clear silicon to stick stones to
clean 2x4, or other sizes.
with a flat face on both sides  - there is an opportunity to make thin
slices for doublets . etc.

Subject: to prevent the virus to spread

Dear friends,
I had enough of the emails with deleted infected attachments coming to me as
I have sent them to somebody. Needless to say I have done no such thing.
But it started to become very annoying.
To prevent these emails spreading I copied and I printed the email
addresses from my address book, and I deleted all your addresses. 
silk@birdamlasu, fob@birdamlasu, gems@birdamlasu are my email addresses.  Please
will you delete my addresses from your books. I will appreciate your help.

Kind regards from Turkey
Oya Borahan

Not having an address book is a good idea but todays viruses will scan your
hard disk drive for e-mail addresses in various type of documents.
Some will also go after cashed web pages and will extract e-mail
addresses so keep your cashes clean as well. Viruses also will
used shared resources on a network as a path to infect many machines
at the same time.

Prevention is anyones best option.
The moral is Check for updates to your virus protection
program as soon as you connect to the internet, each time you connect.

TODAY'S FUNNY ~

Dedicated geologists
Total immersion geologists

Total immersion geologists: Are you totally obsessed with
geology? If so, then you are a total immersion geologist.
Here are the ten warning signs:

1. You judge a restaurant by the type of decorative building
stone they use rather than their food.

2. You manage to turn any conversation into a discussion
of geology, as in: "What did you think of that Superbowl
game last night?" "I must have missed that conference.
Who sponsored it? Geological Society of America?"

3. You refuse to let nightfall stop your field excursions and
continue looking at the outcrops using the headlights of
your field vehicle.

4. You like rock music only because it's called "rock" music.

5. You will try to claw through the water flowing in a stream
to get a better look at the bedrock at the base of the channel.

6. You will walk across eight lanes of freeway traffic to see
if the outcrop on the other side of the highway is the same
type of rock as the side you're parked on.

7. You name your children after rocks and minerals.

8. You're not sure if you have children.

9. You view non-geologists as subhuman.
