Observe the sidearms page from the Atomic Rocket Website.
I've read elsewhere on the site that when objects get to 2kps or greater in velocity, their impact energy is roughly equivalent to their weight in TNT. Anybody know about this?
I know the military did a lot of research on hypervelocity flechette weapons. Weapons like the Steyr ACR were a result. The problem was that 5,000fps isn't quite enough velocity to achieve much of anything (at least not with a 10-grain projectile). But if you could get, say, a 20 grain projectile to about 7,000 fps, what would the end-result be?
Last but not least is the old standby: the laser pistol. Dr. Schilling does not think this is as far fetched as most believe. Erik points out that the problem with a man-portable laser pistol would be the power source. Kinetic weapons are probably going to outperform beam weapons for man-portable sidearms for a long time.
The key to making a laser do bullet levels of damage is pulsing the laser. The first pulse creates a steam explosion and a shallow crater in the skin of the hapless pirate. By careful timing, the second pulse arrives after the steam from the first pulse has dissipated and creates a second crater at the bottom of the first. If you don't delay the pulses, the cloud of steam interferes with laser beam, protecting the target. By altering the variables one can have a laser beam that will penetrate a human body but only bore a little way into metal. As an added bonus, lasers have no recoil. Here follows Dr. Schilling's analysis:
There are four basic technological approaches I would consider based on my personal knowledge, all of which would lead to similar end results if they worked at all.
Phase-locked diode laser arrays
Lots of microlasers on a chip, all working together. Extremely efficient, if you can actually get them to work together.
Diode-pumped YAG lasers
Lots of microlasers on a chip, each working alone. They won't produce a good beam that way, but if you tune them to the right absorption band and direct them all into a YAG crystal, you can get the latter to lase quite efficiently.
Pulsed linear induction accelerators
Fairly conventional technology for producing high-energy, high-current electron beams with external magnetic fields. This one will need to be pushed right up to the theoretical limits to work on a handgun scale, and it will need an unconventional electron source such as a pseudospark discharge.
Wake field accelerators
Clever way of producing high-energy electron beams using the internal electric fields of forced plasma waves. Still in it's infancy, potential unknown but may well be adequate in the long run
