Personal fabber for US$15k plus materials

3 Comments

Following on from yesterday’s post about fabbing your own military hardware, you may be wondering exactly how much of a dent the cutting edge of consumer level 3D-printing technology would put in your pocketbook.

The answer? A personal fabber will cost you just a shade under US$15,000, though the actual printing materials are extra.

Ain’t a lot of money when you think about what it can do, is it? Certainly cheap enough that a reasonably organised criminal syndicate or terror organisation would consider it small change… [via Bruce Sterling; image courtesy Dimension Printing]

Fabricate your own military hardware

2 Comments

Fabrication technology – sometimes known as ‘rapid prototyping’ or 3D printing, among other names – is a real Pandora’s box. The benefits of being able to ‘print’ a solid object are manifold (reduced industrial wastage, low overheads and so on), but the technology doesn’t care what it is that you’re printing out, or who’s doing it… or what they’re doing it for.

This is a topic that Futurismic‘s own Sven Johnson has discussed here and elsewhere, but it’s rapidly moving from the realm of the theoretical into reality. For example, fabrication start-up Shapeways has a video of of a guy who has printed off a miniature remote controlled helicopter:

“So what?”, you might be thinking. But as Bruce Sterling points out:

… all that’s missing from the nightmare scenario is a tiny fabbed bomb and some fabbed GPS. Given those, the Israelis are in for hell on earth.

It’s still a relatively pricey way of doing things, but as the overheads drop the potential of 3d printing to put dangerous tools in the wrong hands rises in parallel with its ability to make our lives better. A rising tide floats all boats, after all.

What the hell is a ‘smart grid’, anyway?

electricity pylonOne of President Obama’s first actions has been to announce his intentions to build a ‘smart grid’ for the US energy infrastructure. WorldChanging explains the concepts behind the buzzphrase, and I’ll paraphrase their five broad categories here:

  • End-user smart metering to use energy more efficiently
  • Systems to integrate electricity generation with electricity storage
  • A communications network that shares data on performance, demand and availability of power
  • An ‘application platform’ that allows third-party utilities to connect the above systems together in useful ways
  • Monitoring and controlling systems that allow the grid to respond to service interruptions in a self-healing manner

In other words, it’s a lot like an internet for power, if you will – not to mention a far cry from the crude lacework of cables and substations we have at the present time. There’s a lot of work to be done, but the benefits of investing the time and money promise to be immense. I wonder what our lot in Whitehall are doing about the UK grid at the moment?

If you’re interested in seeing the sixty odd discreet technologies that break down into the five groups above, the US Department of Energy has made a big old PDF report on smart grids.

Singularitarianism 101: What’s the point of uploading your mind?

4 Comments

exploding mind statueTranshumanist thinker Michael Anissimov has decided to attempt answering the question that almost everybody asks about the the idea of universal mind uploading – namely, why the hell would we want to do it?

His seven reasons include economic growth (topical), greater subjective well-being and environmental recovery, but the one that will probably surprise most of all is his suggestion that mind uploading would forge closer connections with other humans:

Our interactions with other people today is limited by the very low bandwidth of human speech and facial expressions. By offering partial readouts of our cognitive state to others, we could engage in a deeper exchange of ideas and emotions. I predict that “talking” as communication will become passé — we’ll engage in much deeper forms of informational and emotional exchange that will make the talking and facial expressions of today seem downright empty and soulless.

It all sounds a bit like a Greg Egan novel, doesn’t it? Personally, I’m first in the queue for upload (assuming it becomes possible within my lifetime), as I find corporeal existence to be massively distracting – I could get so much more done if I didn’t have this bag of meat to worry about… [image by Alex // Berlin]

Is dumping IQ a genius idea?

4 Comments

Albert EinsteinThe more we learn about the nature of our own intelligence, the more our definitions of it change… but we’re still fairly fixated on the old-fashioned IQ test as a metric for judging how smart someone is. [Einstein portrait courtesy Wikimedia Commons]

George Dvorsky reports on the ideas of one Keith E. Stanovich, who recommends we expand the concept of intelligence to encompass more functions than just number-crunching, spatial logic and the more recent addition of ’emotional intelligence’:

Stanovich suggests that IQ tests should be adjusted to focus on valuable qualities and capacities that are highly relevant to our daily lives. He argues that IQ tests would be far more effective if they took into account not only mental “brightness” but also rationality — including such abilities as “judicious decision making, efficient behavioral regulation, sensible goal prioritization … [and] the proper calibration of evidence.”

Sounds to me like we should start blanket testing for those latter traits at the doors of our seats of government…
