Hello again to any and all interested parties, I am now certain that 
there is hope for the Peoples of Earth getting off world in large
numbers
soon....

Getting cargo to orbit as cheaply as possible is the key, 
it always has been...

the following document is a copy of my web page at 
http://www.sover.net/~geoffk

you can cut and paste from the cut line and save it as an .html

to view offline or go to Sovernet to see it.

Lots of great reasources, links, etc.

Send any comments or corrections to me Geoff Krampetz:

<p><I>"TO PROVIDE CHEAP TRANSPORT OF CARGO TO SPACE, AND MAKE IT
ACCESSABLE TO THE PEOPLE."</I>

<BODY>
<P><B>MISSION STATEMENT</B>
<UL>
<LI>To get cargo to orbit via <i>Coilgun</i> by the year 2005.

<P><LI>To have a Low Earth Orbit(LEO) Cargo Depot that will fuel and
supply 
Single Stage To Orbit(SSTO) vehicles for longer durations in Space, 
Trips to the Moon, Near Earth Asteroids(NEAs), and perhaps Mars.
</UL>

<P><B>COILGUN DESCRIPTION</B>

<p>A <I>Coilgun</I> is a tube surrounded by Superconducting
electromagnetic coils.
Used to launch (SHOCK HARDENED CARGO) to LEO at extremely high
accelerations.
<i>Coilguns</i> with barrel lengths of less than 1,000 miles are
impractical for 
live or fragile cargo due to accelerations of extream magnitude 
(100s-1,000s of times the force of earth normal gravity).

<P>The Launch Tube should be evacuated to reduce the drag caused by
air 
friction.  This makes it necessary to have airlocks at both ends of
the tube
(loading and launching).  There are two doors per airlock.  The
airlock at 
the launching end needs to operate at camera shutter type speeds due
to the 
extremely high exit speed of the projectile(7 miles per second/25,200
miles per hour approx.).  This also makes short 
launch tubes (1 to 2 miles) more practical because a smaller volume is

easier to pump the air out of.  A fast airlock at the launching end
will 
also help to reduce the amount of air that enters the tube when the
cargo 
carrier is shot out of the tube.  The launching end also needs to be
at high
altitude reduceing atmospheric air pressure to as low as possible, low

humidity would also help to reduce drag caused by air friction.

<h3>(Need information on how to calculate Acceleration(Tube length, or
force of propulsion (Gs)), air friction drag, reduction in velocity
caused by gravity, and present it in an easily understandable table.
Eg. how will changes in any of the previous effect speed. How long or
short a tube is practical?)</h3>

<P>A small boost in launch speed (a few thousand Miles Per hour
1,400?) can be
gained by launching  west to east with the Earths' rotation.  Most
rockets 
are launched this way also.  A small rocket engine is needed to put
the 
projectile into a circular orbit (otherwise it will crash into
earth...).
So the projectile may end up looking like the<A
HREF=http://rlv.msfc.nasa.gov/RLV_HTMLs/RLVDCXA.html> DC-X </A>but
with a smaller fuel 
tank and larger cargo space.  The craft must be reusable to hold down
launch 
costs.  Also as any trucker will tell you; the projectile (for lack of
a 
better name) should never travel empty.  On the return trip to Earth
it would 
carry goods or people from space.

<P>A <i>"Coilgun"</i> could launch tractor trailer size payloads to
orbit every 
few minutes, perfect for launching things like fuel for the Earth-Moon
run...

<P>The cost of launching cargo in this manner would be, 
<P><B>THE LOWEST UNTIL NANOTECHNOLGY MAKES SPACE ELEVATORS
FEASIBLE!!!</B>


<P><B>GOAL STATEMENT</B>
<OL>
<LI> get as much information about <i>coilguns</i> as possible
distributed to as 
many people as possible

<P><LI> get people to understand the major differences between
<i>coilguns</i> and 
<i>railguns</i>

<P><LI> get as much hard data as possible in FREE online form
accessible by WWW,
FTP, And a Newsgroup posted newsletter.
(WITH PERMISSION FROM PUBLISHERS AND AUTHORS!)
