Amazing wheelchair replacement

Tuesday, March 20th, 2012

If you’ve ever had to deal with a wheelchair, either because you’re in one, or you’re helping someone who is, you know how limiting they can be. Now there’s something better – the Tek Robotic Mobility Device. It’s an awkward name but the device is anything but – think of it as a Segway for paraplegics that allows them to stand and move without assistance. It’s remarkable. Watch the whole video through to get an idea of just how revolutionary this is.

In the video, Yusuf calls the device to his bedside with a remote-control, gets himself out of bed, goes grocery shopping, maneuvers around a bookstore, and even does some things in the bathroom that we thankfully don’t observe to completion. But these these abilities that most of us take for granted every day are key to the emotional well-being of paraplegic people. The ability to squat down and easily come back to standing is key. And while standing, Yusef’s hands are free to carry groceries or do whatever else he might need them to. Before trying out the Tek RMD, Yusuf, who was a student before his injury, rarely left his home where he lives with his parents.

One of my closest friends in high school and for many (but too few, unfortunately) years after was a paraplegic. I spent a lot of time pushing him around, navigating obstacles and dealing with curbs and stairs. While I don’t think the Tek device will handle curbs or stairs, it’s a vast improvement on the standard wheelchair from almost every respect. You might think that it was developed by a smart West Coast startup, but it comes from Turkey. I wish Bob had lived to be able to use it.

The future is gender distributed

Wednesday, February 22nd, 2012

William Gibson has said “The future is here, it’s just not evenly distributed.” In a guest post on Charlie Stross’ blog, Cat Valente riffs on that idea, looking at how future tech is distributed, or not, between the genders. It’s a fascinating read.

I don’t think there’s some dastardly man in a high office making Mr. Burns fingers and saying: EXCELLENT. I have oppressed women for another day! Let us celebrate! (Except the PMs who wanted to take away benefits for childless women–but not childless men.) This kind of thing is always more subtle than that. People who have imbibed from their culture that men and business are important and women and the home are slightly distasteful and irrelevant spending their time on inventions applicable to one and not the other. Corporate managers approving projects along the same lines. Everyone performs their upbringing in their work in one way or another. Obviously, I don’t consider business a male bailiwick and the home the kingdom of woman, but a whole lot of people do, and a goodly number of them have a massive influence on the allocation of R & D funds and the political narrative than I do. Right this very second, here in the US, we are having an actual, serious, if incredibly stupid, conversation about whether or not women should have easy access to birth control. We are having this conversation because significant humans in our government believe women should not have access to it at all. I’m super excited about that, because it means it’s 1965 and we’re gonna go to the moon soon.

And Japan is HARDLY alone. C.f. that entire viciously moronic conversation about the care and feeding of my uterus. I merely noticed it for the first time over there. The article I linked to is fascinating because it is a very high tech response to a domestic issue, which is something I don’t come across very often. Most of us are cooking in kitchens quite recognizable from 40 years ago. The Roomba in the corner of my living room is about the only chore-class object in my house that that same grandmother would not have used in cleaning up after my parents.

Iron Giant

Saturday, February 11th, 2012

In my first job out of university I worked for a company that made marking devices and had a fairly large machine shop. I went to a couple of trade shows where I got to see really big mechanical presses in action – thirty or forty feet tall beasts that could squeeze an iron bar down to a sheet of foil but were also precise enough to print a logo on top of an egg. But none of these compare to Alcoa’s Iron Giant, the biggest press in the United States, which has just been repaired and is going back to work making parts for the F-35 Joint Strike Fighter. This is one seriously impressive machine.

The Fifty, as it’s known in company shorthand, broke down three years ago, and there was talk of retiring it for good. Instead, it was overhauled and is scheduled to resume service early this year. One of the great machines of American industry has been reborn.

A forging press is—begging the forgiveness of the engineering gods—essentially a waffle iron for metal. An ingot, usually heated to increase its malleability, is placed on the lower of a pair of dies. The upper die is then gradually forced down against the ingot, and the metal flows to fill both dies and form the intended shape. In this way, extremely complex structures can be created quickly and with minimal waste.

What sets the Fifty apart is its extraordinary scale. Its 14 major structural components, cast in ductile iron, weigh as much as 250 tons each; those yard-thick steel bolts are also 78 feet long; all told, the machine weighs 16 million pounds, and when activated its eight main hydraulic cylinders deliver up to 50,000 tons of compressive force. If the logistics could somehow be worked out, the Fifty could bench-press the battleship Iowa, with 860 tons to spare.

It is this power, combined with amazing precision—its tolerances are measured in thousandths of an inch—that gives the Fifty its far-reaching utility. It has made essential parts for industrial gas turbines, helicopters, and spacecraft. Every manned U.S. military aircraft now flying uses parts forged by the Fifty. So does every commercial aircraft made by Airbus and Boeing.

SF predictions: hit and missed

Wednesday, February 8th, 2012

On Charlie Stross’ blog, Cat Valente (who’s filling in for Stross while he travels), has one of the better articles I’ve seen about science fiction and predictions. There’s a popular idea that SF predicts the future, but that’s not the case – there are very few instances in the literature where SF predicted a technology, a device, or an event in any real detail. Rather SF imagines futures that might be and how we’d live in them. More often than not, SF authors get it wrong, usually by omission – no one predicted that the moon landing would be televised, for example, although there were many stories about landing on the moon.

Valente looks at Star Trek, Deep Space 9, and makes some cogent observations. Star Trek got some things right, but they missed a lot – the Internet and social media, in particular.

As I watch everyone interact on the station, the lack of social media sticks out hugely to me simply because it is how so many of us interact with each other now–and especially over long distances. There is no hashtag for DS9 workers to tweet LOLSisko macros or talk to families back home. Everyone uses voice/video communication rather than text despite the security issues this obviously poses (and of course a social network of any kind poses security problems in and of itself, but provides rich narrative opportunities in that arena which I’ve yet to see explored much) and the fact that we are seeing even now many people shy away even from the telephone when given an alternative. We have the videophones of science fiction past–and no one much cares. We use it sometimes, but it’s far more of a pain to make yourself presentable onscreen, get the kids and dogs to leave you alone for long enough to Skype, and carry on an etiquette minefield of a conversation when a quick text or email will do for most business.

This doesn’t begin to cover the constant “come here and see this” requests, where said person will not be able to come there and see that due to falling plot. We live in a world already where no one need come and see anything, a quick picture upload obviates the need for O’Brien to come squint at your shit in person. Part of the reason, I think, that Minority Report continues to be a watchwod for interface technology is that it showed a new(ish) way for people to interact with technology. In DS9, instantaneous information tech is available and evenly distributed, but the writers do not live in a world, yet, where anyone has begun to figure out what to do with it. So walkie talkies are still, in 1999, the model for communication. DS9 cares about physical presence in a way we are already beginning to leave behind.

As for getting it right, Ben Bova nailed e-book readers and self-publishing in his 1989 novel, Cyberbooks. It’s not surprising that he got e-book readers – writers as far back as Isaac Asimov had them or something like them, but he went deeper and looked at how they’d affect the publishing industry.

The book focused on the invention of the first ereader, the Cyberbook. It was more of a satirical take on the publishing industry than a prediction of the near future, but that just renders the accuracy all that much more amazing. Here’s the money quote:

“Cyberbooks will bring down the cost of publishing to the point where thousands of writers who can’t get their works published now will have a viable marketplace for their books”.

Doesn’t that sound like the current state of self-publishing?

While it’s not clear that Mr. Bova predicted that so many would bypass the traditional gatekeepers, there is still a ring of truth to this. Would you believe it was just tossed off in a brief phone conversation near the end of the book? And there’s even more predictions in the book which have come true, including online sales and the amount of effort publishers put into resisting change.

Finally, I have to mention John Brunner’s The Shockwave Rider.

The Shockwave Rider is a science fiction novel by John Brunner, originally published in 1975. It is notable for its hero’s use of computer hacking skills to escape pursuit in a dystopian future, and for the coining of the word “worm” to describe a program that propagates itself through a computer network.[1][2] It also introduces the concept of a Delphi pool,[3] perhaps derived from the RAND Corporation’s Delphi method – a futures market on world events which bears close resemblance to DARPA’s controversial and cancelled Policy Analysis Market.

Brunner got a whole bunch of things right, mostly involving the social and cultural implications of a widespread distributed computer network. But his network wasn’t the Internet – it was the phone system – and his hackers punched out long strings of touch tone codes to enter programs. He got the technology wrong, but everything else that followed from it was pretty much dead on.

Why the “Check Engine” light must be banned

Wednesday, January 18th, 2012

Here’s an article that focuses on usability, but in automobiles. In modern cars, why is there a “check engine” light instead of a more informative diagnostic display? Certainly the computers that run automobiles now can display more information about the state of your engine. It couldn’t possibly be because the manufacturers want you to go to their (overprices) dealers’ service departments? Could it?

I should note that with all the cars we’ve owned recently, the most common cause of the light coming on has been a gas tank cap that wasn’t on tight.

What’s not to like is that when something goes wrong, all the average motorist sees is that little drawing of an engine bisected by a lightning bolt. And all that tells them is basically nothing. The “check engine” light is the MIL (Malfunction Indicator Light) of the OBD-II system, and illuminates whenever a fault is detected. To see exactly what sort of fault takes a “special scanner” that plugs into the OBD-II connector. These scanners are almost always owned by mechanics or dealers. Independent people can buy scanners as well, or cables to connect laptops, smart phones, etc., but people who will do that are not the ones who need to worry about the check engine lights.

My mom, for example, is never going to be able to connect her laptop to the OBD-II connector somewhere under the dash in her Passat; it’s hard enough explaining to her how to connect a printer to her Mac. If her Passat just told her what codes were being thrown, she would at least have an idea about the condition of her car.

“We need a federal mandate that bans the generic ‘check engine’ light in new cars.”

But better yet — the state of things now is that your car actually could do more than just throw an error code at consumers. It contains an advanced system to diagnose itself, but the actual information from that diagnosis is not available to the car’s owner; the average owner must pay a dealer or mechanic to provide him or her with the codes, and what those codes mean. This is absurd. Early on, when in-dash displays were rare, one could understand why cars didn’t just display what codes were being thrown (though I think a little in-dash receipt-type printer would have been cool).

The world in 2032 and 2092

Monday, January 9th, 2012

At the beginning of each year, The Economist magazine publishes an issue that looks at the state of the world and what it means for the coming year. SF authors often do the same thing but they tend to look a bit further ahead. In the case of Charlie Stross, he’s taken a look at what the world might look like in 2032 and 2092. Stross is one of the few SF authors who’ve seriously attempted near-future SF, which is one of the hardest sub-genres to work in, and he’s got the chops to try this. If you want to get an idea of what the world your children will be inhabiting, read this post. It’s quite long, but well organized and absolutely fascinating. Here’s some of what he has to say about 2032.

Energy: oil will still be available and planes will still be burning it. Prior to Fukushima I was predicting a big renaissance in nuclear power. Now … I’m still predicting it, but I think it’ll take an extra 10-20 years and people are going to be a lot more cautious. Chernobyl could be written off as Soviet mis-management, but Fukushima, while a lot better managed and less damaging, is in some ways more alarming because it underscores the need to design nuclear plant to be fail-safe even in the face of a once-per-thousand-years event. Which drives the cost of nuclear right up from an already high baseline.

Solar is getting cheaper rapidly, and is now actually rolling out in significant quantities, but runs into the “how do you store it?” problem. What I think we may see is solar plant that, rather than producing electricity, is designed to produce electrons and use them immediately to electrolytically split water, liberating hydrogen, which can then be converted into something more storable … like methane (using atmospheric CO2 as a carbon source).

Coal is going to get deeply unfashionable. It’ll still be with us in 2032, but with expensive scrubbers and carbon capture plant and, more likely, subterranean gasification. Which is still fossil fuel, but is less obvious to the naked eye from the spoil heaps.

Fusion will be 30 years away. But by that, I mean commercialfusion reactors. There will be a prototype under construction, with a turbine hall that will deliver base load to someone’s grid (probably France’s), when it’s running. Which won’t be most of the time, because it’ll be a prototype and a hangar queen. And they’ll still need 30 years of research into the effects of neutron embrittlement on construction materials before they’re ready to start building them on production lines.
