Just out of curiosity, what does the battledress look like? Is the from the
pictures from MegaTrav & the DGP illustrations or the new stuff that's in
the RCES equipment guide?

Has anyone else noticed that 0.04*(Pi)*r^2 gives exceptionally light 
masses for Gauss Rounds.  Follow this for a second...

Lets say a cylinder 6mm in diameter thus 30mm in length.
The FF&S equation gives a mass  0.04*(3.14)*(3)^2=1.13 g/rd
this gives a density of (1.13 g)/(.85 cm^3) about 1.3 g/cm^3!
This just a little more than the density of WATER!
Please check my calculations and tell me that I am wrong!

The result is that you need ridiculously high muzzle velocities to get 
decent energy out of your weapon.  Even if you use the density of 
aluminum (2.7 g/cm^3) you get a round with double the mass of the FF&S 
rules.  This will allow the same energy with about 2/3 the muzzle velocity.
Go to even higher density material such as steel and youre 5-6 times the 
mass of the FF&S round.

>From now on im using 0.1 * (Pi) * r^2 to determine gauss round mass.  
Even this is on the light side.

Due to some odd musical system stuff here, I lost the original
message, but here's some relevant info:

I did something on that last year in a couple of postings on Traveller
Astrography I did for the TML (at about the same time I did the galactic
schematic GIF showing Charted Space available at ghost.)  From those
postings came this list, with spectral classes and positions from the
DGP sector data:

"Official" Star Systems (GDW and DGP):

Terra      (1827 SolRim)    G2V            Sol
Fenris     (1830 SolRim)    F5V            Procyon {alpha Canis Minor}
Barnard    (1926 SolRim)    M5V            Barnard's Star
Prometheus (2027 SolRim)    G4V K2V        alpha Centauri A/B
Sirius     (1629 SolRim)    A1V F3D        {alpha Canis Major}
Fomalhaut  (1024 SolRim)    A3V K4V        {alpha Piscis Australis}
Iilike     (1429 SolRim)    G8V            Tau Ceti
Capella    (1440 SolRim)    G4III M1V M5V  {alpha Aurigae}
Altair     (1522 SolRim)    A7V            {alpha Aquarii}
Shulimik   (1530 SolRim)    K2V            epsilon Eridani
Vega       (1720 SolRim)    A0V            {alpha Lyrae, Gwathui (vegan)}
Castor     (2236 SolRim)    KOIII          {alpha Geminorum}
Pollux     (2339 SolRim)    K0III          {beta Geminorum}
Arcturus   (2921 SolRim)    K2III          {alpha Bootes}
Antares    (2421 Antares)   M1Ib A0VI      {alpha Scorpii, Mika (vilani)}
Deneb      (1925 Deneb)     A2Ia           {alpha Cygni}
Gashikan   (2732 Gashikan)  M6III KOIV     X Ophiuchi

>From HIWG files at ghost.cc.missouri.edu.  There are probable errors
here:  Cicero can't be Aldebaran, because the subsector rimward of it
is Aldebaran subsector in Aldebaran sector!  Depot can't be alpha Oph,
since both listed stars are dwarfs, etc.  These should be checked 
before fully accepted, IMHO.  Many do seem ok.

Agidda     (1824 SolRim)    M4V            Ross 154
Boskone    (1214 SolRim)    K2III          alpha Indi
Cambria    (2407 SolRim)    K2III          epsilon Scorpii
Cicero     (0938 SolRim)    K5III M2V      Aldebaran {alpha Tauri}
Depot      (1911 SolRim)    M6D K6D        alpha Ophiuchi
Ember      (2227 SolRim)    M5V M6V        Wolf 424
Gashidda   (1127 SolRim)    F8V M8D        epsilon Ceti
Ishadar    (0606 SolRim)    KOIII M4V      epsilon Cygni
Junction   (1929 SolRim)    M6V            Wolf 359
Loki       (2228 SolRim)    M5V            Ross 128
Meshan     (1526 SolRim)    K5V            epsilon Indi
Midway     (2029 SolRim)    M2V            Lalande 21185
Mirabilis  (1332 SolRim)    G5V            82 Eridani
Nusku      (1822 SolRim)    K5V K7V        61 Cygni A/B
Stralsund  (0618 SolRim)    A7IV           Alderamin {alpha Cephei}

I made the following guesses on some stars, based on their positions and
spectral types before I saw the above list:

Dingir     (1222 SolRim)    K0V M1D        40 Eridani A/B
Markhashi  (1529 SolRim)    M5V M6V        UV Ceti A/B  (maybe not, is flare
star)
Peraspera  (2028 SolRim)    M5V            Lalande 21185
Junction   (1929 SolRim)    M6V            Wolf 359
Meshan     (1526 SolRim)    K5V            epsilon Indi
Nusku      (1822 SolRim)    K5V K7V        61 Cygni A/B

Besides the Solomani Rim:

"Official" Star Systems that haven't been located:

Spica          B1V.   Somewhere in Spica Sector, probably subsector C.
Acrux          B2IV.  Somewhere in Alpha Crucis Sector.
Denebola       A3V.   Somewhere in Alpha Crucis subsector I (Denebola).
Aldebaran      K5III. Somewhere in Aldebaran subsector B (Aldebaran).
Canopus        F0Ib.  Somewhere in Canopus sector.
Delta Cephei.  G2Ib.  Paranoia Press put this variable star in their
                      version of Beyond Sector.  Don't know if it's 
       still there.

Also, in the DGP sector files I found the following planet names, with the
star locations and spectral types appear wrong:

Beta Cygni-4 (3006 Ilelish)   (Possible right position, but *bad* spectrum)
Gamma Lupus-2 (2104 Ilelish)
Mizar-5 (1011 Old Expanses)

Unidentified Nearby Supergiants (DGP sector files):

Eakhoi       (2123 DkNebula) F8Ia      (Polaris?  Is a bit too close to Terra.)
Sardas       (0839 Mendan)   F0Ib M7D
?            (1530 EmptyQtr) M4Ia M4D

Interesting objects to watch for (my best guesses):

Regulus        B7V.  Probably somewhere in Aldebaran Sector, range 25pcs.
Betelgeuse     M2Ia. Probably in sector just rimward from RimReach).
zeta Ophiuchi  O9V   Lishun sector?  (At same approx. range as Antares)
gamma Velorum  WC7   Wolf-Rayet star, may be in Hiver space.  (Even rarer
                     than an 0-class star (200 in galaxy) -- could attract 
      Darrians and Church of the Stellar Divinity members.)
rho Ophiuchi Dark Cloud.  Collection of nebulae.  Probably in coreward
                     Trenchan Sector.  
      
Two open clusters should be in or near Solomani space: the Hyades (40 pcs.) 
and the Pleiades (120 pcs.), both with hundreds of stars contained in just
a few parsecs!  Both are near the Aldebaran line-of-sight from Terra. (See
a star chart.)


Hope this helps!

Here's another thought about a beanstalk...
What is the heatsink effect of the stalk? It is sticking out into 
hard vacuum and out there night/day temperature is dependant on solar 
radiation. So would this cause a net increase or decrease in the 
planetary temperature? Decreases could certainly be useful in 
reducing global warming! As a reference consider the heat-sink below 
the 'poles' on the ringworld. So anyone??

Message-ID: <37C04550C95@fs2.cp.umist.ac.uk>

Here's an idea for a weapon system to trash battledress:
At high TL it should be easy to design a propelled grenade/mini 
missile of about 25mm bore which will destroy battledress, a current 
HEDP grenade probably would. Note that 25mm is about 10ga, so stick 
these in an auto-shotgun (P.S. I believe Colt are doing exactly this 
at the moment). Further add solid-state guidance to increase the 
chance of hitting the target (note that a current 40mm grenade is 50% 
fuse - this would be relatively tiny). That ought to be quite 
effective. Now you could link that to a smart-HUD to aquire targets 
with thermal/NAS/etc., and a redesign to fire grenades up which then 
home down on the target would allow this to be converted to a 
backpack.
