Those who do not know history are doomed to patent it. [To acquire or issue patents]
As others have mentioned, morse code users recognized the style of each other's signals a long time ago. Typing patterns have been used in various ways also; one of the less obvious was in decoding typed documents through spy transmitters which provided recorded audio of typing. Of course, Turing test tools have done the reverse when a computer emulated human typing for the purpose of seeming to be a human typist. An obvious extension of the concept were the several writing pattern devices which measure pen pressure, speed, and/or acceleration during a signature. Several of these have also been used in fiction over several decades, but "Seven Days of the Condor" contains the major example of fiction idea searching and I'm not aware of a central source (unless The Encyclopedia Of Science Fiction has relevant index entries).
I will note that acquiring patents and then asking Slashdot to do your prior art search is a novel approach. Have you patented this?
I also noticed that the rescue plans seem to not include Russian and ISS resources, only NASA resources.
The Progress which was sent to ISS could have reached Columbia. Columbia was in a lower orbit, and I'm sure the Progress launch rocket was not built for a specific orbit and could have been reprogrammed for the Columbia orbit. I don't know how easily the payload could have been replaced, but if Columbia was waiting in orbit for a month there should have been time to change Progress payloads. A Progress is not built for reentry, so could only carry supplies -- although perhaps also repair parts.
The astronauts were wearing their emergency spacesuits, so everyone did have a suit. I don't know how long those can be used for EVA. Someone would have had to go look at the damage. Someone would have had to get the first batch of supplies from Progress. That first batch could include supplies for more suit time (I assume not a full EVA suit and thruster pack), so the rest of the supplies could be retrieved. Whether the supplies would have replenishment or repair equipment depends upon what was found to be needed and could fit.
ISS was too far for Columbia to reach. I'm sure Progress could not carry enough fuel to push Columbia toward ISS (whether by using Progress as a tug or refueling Columbia -- and I doubt the fuel tanks were designed for fueling in space). ISS did have its "lifeboat" Soyuz. Perhaps that lifeboat could have reached Columbia. A Soyuz probably does not have enough fuel to quickly alter orbit to Columbia, but there would have been a month to loop around the Earth and/or Moon to change orbits with minimal fuel. Another possibility would have been to have Progress bring Soyuz fuel to ISS so Soyuz could reach Columbia.
The Progress on ISS was full of trash. It could have been refilled, but probably could not reach Columbia anyway.
A Soyuz is designed for 3 people, and 7 were aboard Columbia. I'm sure if Columbia were known to be fatally damaged, all the people who could fit in a Soyuz would try to return. If a Soyuz reached Columbia, although it definitely could rescue three people I suspect that any three would prefer to risk themselves in trying to rescue others than to go in safety.
The April Soyuz could carry 3, or could have been modified before launch with seats for however many would try. Maybe the Soyuz which was launched in April could have been launched with one of the world's rockets. Maybe the scheduled Russian launcher, maybe welded to something else.
The ISS lifeboat Soyuz perhaps could have reached Columbia. If the onboard fuel could not reach Columbia, perhaps the Progress could have brought fuel and an extra seat for an attempt at rescuing the other 4.
There are riskier possibilities which would be less likely to succeed.
Soyuz Tugboats. Push the ISS Soyuz with other craft. I think ISS had its previous Progress attached during the Columbia flight, so two Progress vehicles could have been near ISS. If the lifeboat Soyuz could not carry enough fuel to reach Columbia, perhaps it could first be pushed by one or both Progress (particularly if the second Progress was modified on the ground to carry more fuel). There are other craft in orbit, but probably few could change orbit enough to help. Perhaps there were satellite launch vehicles on the ground which could be tossed up in proper orbits to help push (a satellite with a geosync booster has a lot of push in it).
Columbia Tugboats. Columbia is heavy. The only place where it could be pushed for rescue would be ISS, which was in a higher and different orbit. Maybe geosync boosters could have helped, but I doubt there are enough available. I don't think pushing Columbia so the ISS lifeboat could reach is possible nor would it make sense, as pushing the lifeboat is easier.
Tether tricks. If there is something like a rope on Columbia, put someone on the end of it. Spin Columbia. Release to toss them toward ISS. Catch
An 80,000 volt jacket will only generate an electric field able to spark across a very short distance, otherwise the wearer's wrists and neck would have glowing decorations.
Remember a lightning bolt has enough power to jump across five miles of air, a fairly good insulator. With a reach of 25,000 feet, a conductor or insulator in the last few feet isn't going to stop it, although a conductor might tend to guide the bolt. A weak electric field won't matter unless the bolt leader happens to pass very close -- and as standing within ten feet of the strike point of a bolt is double-plus ungood, such a minor influence does not matter.
There is a slot at the top of the ramp from which the time-reversed water comes out, having been pumped from the pool at the bottom. Normal water is pumped to a slot to create the waterfall. The types of water do not mix in the pool because the pumps are started at different times such that the flow of the time-reversed water has already been determined before the normal water is added.
It's really quite obvious.

Mastering Light

It sounds like you get bursts of upward conversion and downward conversion, as the conversion is done by the movement of the reflective surface. So upward conversion happens while moving toward the light, but as the mirror moves away to its starting point there will be downward conversion. So you'd get a beam with bursts of red shift and blue shift taking place, but the "wrong color" will be blocked from coming out. This color filter is what makes it different from a simple moving mirror. For constant conversion you'd have to use several devices and switch between them at appropriate times, or several running in parallel with the pulsed beams being combined.
The energy for conversion comes from the shock wave, the light is merely bouncing between reflective surfaces as it does in a laser. In a laser, usually all the lasing light is in a single frequency. A laser normally works by using a weak mirror, and the color is whatever is inside the laser (some laser mirrors simply use a hole for the beam, which is an interesting way of having a "weak" mirror). This device instead uses a color-sensitive mirror to let the light out when it reaches the correct color.
I do have respect for the design and engineering of an experiment which will involve bullets as a mechanism. Sometimes brute force is the simplest way to test something, such as when the question is "Is it unbreakable?" versus "How strong is it?".
Metaphysically provable or not, I am quite convinced that my creative capacity is insufficient to create a universe this complex solely for my own edutainment.
Well, apparently the person reading this does have sufficient creative capacity to have imagined all of us. And to have imagined that you think the universe is more complex than your imagination.
Yup, that's why I suggested the conductor be on the outside. If a wire is wrapped up to the end, it can be bent into the end, which will help ground the inside. But as the material is not intended to be an insulator, it may leak enough to let the charge reach the surface where it can be drained.
I forgot about the magnetization. Steel can be magnetized by stroking. Apparently the magnetic domains can be aligned by physical manipulation.
I was thinking of a "shop vacuum", a drum with a filter and blower on top. Stuff gets sucked into the drum, with most of it falling to the bottom or circulating around the wall until it slows. Often called a "wet/dry vacuum" due to being able to handle water. But small canister vacuums are also popular in workplaces, and those simply have a filter bag ahead of a fan -- that would be enough for drilled metal, assuming the fan motor doesn't mind being run for as long as this takes.
Static electricity is probably created by the airflow, so you're right that caution should be taken. Probably it would be sufficient to wrap aluminum foil around the hose a few inches from the intake end, with a grounding wire connected from it to the computer case. How the foil is held doesn't matter, as long as it is not with glue that might insulate it too much. The only static build up should be in the few inches to the end, and that could be reduced with one strand of wire somewhat coiled around the tube from the foil to the end.
But you might be using a stiff wire to hold the thing in place anyway, and if that is electrically connected to the case that should be enough.
That is, instead of making a copper sheath with a grounding strap it probably is enough to anchor a wire coat hanger in some holes on the case or rack, sandpaper or file it in several places to remove any insulating covering, and twist the wire around the end of the hose to hold it in place. Use whatever level of tech you are comfortable with, it's your rescue project.
I was suggesting sucking while drilling to prevent having filings stuck to components in ways which resist vacuuming after the drilling. Should be particularly effective on the smaller filings which would otherwise be most likely to get stuck in miniscule cracks.
Don't suck in any jumpers or batteries that you can't replace.
When done, tap the hose while in operation to try to shake filings out of hose to prevent their falling out on the next project.

In the morning, you're accelerating toward the Sun so you're moving closer to the speed of light so its speed is less than in the late afternoon when you're moving against the Sun's gravitational acceleration and thus slowing away from the speed of light.
