Replicators Are Coming

While in this particular instance the term "replicators" better fits the Stargate SG-1 definition (think chip-size TNG Borg) than the Trek definition, elements of both are present.

The RepRap is a self-replicating rapid-prototyping machine. I've seen a large rapid prototyping device before at a university, and they are magnificent devices. Building a plastic object layer by layer, you end up with a near-perfect model (or, if it was a plastic object you wanted in the first place, a near-perfect object ready for use).

Calling it "self-replicating" is a bit of a stretch at the moment. In addition to a wealth of additional parts (including steel rods and assorted electronics), it must be hand-assembled and requires a computer to operate. However, future RepRaps are intended to have the ability to do circuitry. This sort of thing is manually possible even now . . . there are special conductive-ink pens that allow one to draw working low-voltage circuits. Microprocessors are certainly a long way off for any such tabletop technology, but the germ of the idea is there.

Even with what it can do now, it would be theoretically possible for RepRap to put certain companies out of business, if the units existed in sufficient numbers. For the most low-key example, you can imagine a simple "make solid" plug-in to convert 3-D graphics models (LightWave or POV-Ray or what-have-you) into solid shapes that the RepRap software could build. This would have the effect of savagely reducing the business of certain fringe model kit and toy makers. Even for more advanced model-builders who wanted to light their models, designing little conduits (or large open spaces) for running wire or fiber optics is hardly outside the realm of possibility.

The best part of RepRap is the open-source nature of it. You can make your own right now.

The active mind can certainly see all sorts of potential for a device like that. But, I want you to imagine the future. Picture a replicator similar to RepRap capable of working with many materials. I'm not even talking about nanotechnology dreams, here, but a real assembler capable of using small quantities of metals and plastics. Even with the most basic processors, what common items couldn't be made with such a thing?

This is the coming revolution. While industry will remain a step ahead for a long while owing to quantities of scale and special needs and whatnot, home manufacturing will slowly whittle away at it as time passes.

Of course, the more things can be made simply, the greater the danger, too. If you can make a simple analog telephone at home, you can make a sealed detonator circuit just as easily. The same is true even today, to be sure, but with so severely lessened cost and thought and effort requirements I have a feeling the problem would worsen significantly.

Will we make it past a home manufacturing revolution? Will nano-tech based home replication systems come and will society survive? It remains to be seen. But we're not too terribly far away now from finding out. The world of 2100 will either be extraordinary to see, or positively horrifying.

A Neat Toy

SensibleUnits.com can give you a better grasp of some of the object sizes, masses, or what-have-you that we deal with in the debate.

For instance, when I plugged in 289 meters (the length of NCC-1701), I learned that this was 3.6 Airbus A-380s side by side (i.e. wingtip-to-wingtip). It's that sort of little observation that can cause the brain to springboard elsewhere. For instance, given that the Airbus A380 carries over five hundred (and up to eight hundred) seated passengers, you're talking about room for almost two thousand people, with most of that space being taken up by wing.

But then I've talked about such things before.

Still, it's a neat little toy to put things in better perspective.

Phoenix "EDL"

Tomorrow this happens. Due to the more massive nature of the lander the old Pathfinder airbag system isn't useful, so the Phoenix Mars Lander must use heat shield, chute, and retro landing rockets.

Gotta hand it to NASA. Not only is the lander going to do its thing (we trust), but in addition they have a pretty good PR team doing their little filmmaking efforts.

("Give me your most attractive Phoenix team members, the director from the Bourne movies or someone who can fake it, and some of the CGI guys from Foundation Imaging or nearby, stat!")

EDIT: Nailed it! Good job NASA!

Neat Research: "Wink of an Eye" (TOS)

This is interesting research. Youtube user albion432 slows down some of the accelerated Scalosian speech so one can make it out.

NOT SAFE FOR WORK ... But funny as hell.

Okay, I warned you.

If you're at the office, or near family, friends, pets, or anything else with ears, don't say I didn't warn you.

There, see, I warned you again.

Now click here. Watch the video. Don't drink anything before doing so, though, because that wouldn't be safe for your monitor, either. I'm just sayin'.

Such Primitive Ablative Armor, Ha!

I'm interested in knowing more detail on the reference in this story about NASA's lightweight ceramic ablator heat-shield material withstanding 5,000 degrees Fahrenheit. Obviously that must refer to a certain thickness lasting a certain length of time before burning off (i.e. ablating) entirely, but no data is provided.

Nonetheless, that's pretty cool. Might've been helpful on the hull of the Invisible Hand, which managed to get pretty cooked during a low velocity atmospheric entry.
