Gun and Military people will find this interesting.

Sch fi and video games predicting the future once again. I wonder if the same tech can be used for putting small satellites into space far cheaper than rockets.
 
The projectiles have been around for awhile. Railgun looks pretty sweet.
 
There was an engineer out of Missouri I met about a decade ago, that told us how he was working on a prototype tank cannon that used a magnetic pulse to fire a shell. No gunpowder, so it drastically reduced the chances for explosion within the confined spaces of tank. The other cool thing they were working on was that they were experimenting with setting the barrel up in such a way that when the shell exited, the sudden release of all that heat at such high pressure worked much in the way as air-conditioning and cooled the barrel near immediately. He said that the heat on a barrel after repeated firing could distort the aim of the barrel significantly and it stayed that way until it cooled.

The guy was really creative and PBS was supposed to do a science show built around some of his inventions, but it fell through. I met him through a friend at a car tech show at the Hearst Castle, where he unveiled a motorcycle that ran on pure ethanol. He had done the conversion for Darryl Hannah on three of her cars, from gas to run on E85.
 
Cowpoke,

Dr. Gerald Bull had designed and Saddam Hussein had begun construction on what amounted to a very long artillery "supergun" which most people familiar with the project believed was quite capable of launching satellites.

Mossad agents took him out when he went rogue and started working closely with Saddam.

It makes a great deal of sense. You would need a really long one so that the speed up was shower and g forces weren't enough to tear up the payload. Use natural land formations for a ramp. Initial costs would be significant, but each launch would be very inexpensive you would think.

Only drawback would be the extremely limited orbital paths if it were fixed in place..
