Why then is he worring about liquid Helium being incredibly good at
getting out of sealed containers?

No, I was just worried about keeping the stuff in the tanks for 20 years,
and of course the weighnt of the tank itself. One distinct advantage of
lithium is that it is a solid metal at room temp. So It doesn't boil off or
need a tank. However since Li produces about 75% of the power per Kg
(1.596 E14 vs 2.059 E14). This would obviously take a big hit out of the
spec impulse.

Yes, I'm hoping to set up a real-life listserv on my machine to let us do
-real- email discussion groups. I just have to fine a cheap or free listserv
for Windows NT.

I think the permanent server will be at SunSITE, but SunSITE will actually
just be a mirror of my site at work. That way all the real traffic will go
to SunSITE, but you guys will still be able to update your stuff, and it will
appear there. Also, it's good to have two copies of everything.

Re: contents... tables versus imagemaps? imagemaps are pretty widely
supported. Problem being people on low bandwidth connections using lynx...
always a good idea to supplement with a simple text menu underneath the
imagemap. 

Also, I haven't forgotten about the ship data - waiting for a free Macintosh
(the data is on a Mac disk)

Cool, I was just thinking of having a MailTo function for the groups. I'll cut
a discussions group branc as soon as I can. -- Maybe I'll wait to see if my
maps work first.

Sounds good. One thought. Does your workstation and SunSite support the
same Map format?

Already have done.

Hum, lost in the Intelian wastlands without an emulator. ;) 

Hum, you guy are the only PC based web cutters I know of. But I'm sure
their must be another.


Look at the bright side. I also have lots of stuff for a Space Development
Project group (Concrete space stations of 2001 size for 30 billion using
current tech and ground launch supplies, Harvesting comet cores and
leaving Babylon 5 sized colonys as waste by products, etc..). If we can get
these groups going we can get intrest from other space groups. 

I kind of like doing the web pages too. (Old saying, nothings duller then a
tool grinders tools.)

With luck I'll have an answer and new job by then.

Thanks, Kelly...;-)

However, as I advised - stay calm, all of the mini-LIT... Probably due to a
certain haste, I have mixed up the "vacation" messages - the proper one
should be:

So - I am back already, sorry...
Though, fortunately ;-)), I am still very busy, so I will not be too active on
the list. 

Cheers,
