Nanotech Pinball and Miniature Engines 171

glenmark writes "Researchers at the Solid State Electronics Laboratory at Chalmers University of Technology in Sweden have developed the world's smallest pinball game. The video is fascinating. The flippers are electrostatically-actuated monocrystalline silicon cantilevers. I hope Pat Lawlor and Steve Ritchie see this. I have a feeling they would get a kick out of it." And in another nanotech story, psmears writes "Three hundred times more powerful than ordinary batteries, but much lighter and smaller? Researchers at the University of Birmingham have developed a micro-engine that will allow people to charge mobile phones using lighter fluid.

      Huh?

      It is an MPEG codec. DivX is an implementation of MPEG-4. If you want source code for a decoder see the ffmpeg [sourceforge.net] (as libavcodec) or xvid [xvid.org] codecs. Between then, I've not see an OS with a POSIX layer that's not been able to compile a decoder engine. Granted, there are large bunches of optional parts that the various decoders don't all cover, but I've not yet see any problems with ffmpeg decoder.

      If by MPEGS you mean MPEG-1, then yes - that is slightly more portable than MPEG-4 codecs, but not noticably (better support on embeded systems). They do however, have poorer picture quality, and larger bitrates. So, it's not really a good choice for internet distribution. MPEG-2 would also be better than MPEG-1, but it's also not quite as good as MPEG-4, interms of low bitrate quality. And for a web demo, the lower the bitrate, the better.

      If you've got a particular platform in mind, then drop a line, and I'll see if I can find a pre-compiled setup for it.

    Will the Diamond Age begin in our lifetimes?

    I'm personally of the opinion that when the nanotech revolution starts, it'll happen so shockingly fast that applications, society and governance will take decades to catch up -- think internet x10.

    In a world of pervasive nanotech, I suspect the next really big industry will be power generation; it'll require a step up in juice unlike any seen since the start of the century. Fortunately, nanotech will hopefully solve some technical problems (superconducting power transmission, materials suited to support fusion, etc) at the same time it's demanding this huge level of power generation.

    Of course, in a world of pervasive nanotech, our existing governmental and societal structures are in a lot of trouble... We live, as the ancient Chinese said, in interesting times (and I mean that in the spirit in which they did).

      I'll take up part of that discussion.

      While nanotechnology has many great potentials, they are still in a hazy future. Lasers were once seen as the technology that would transform the world. Same with Computers. Yet the bulk of the world is still relatively unchanged by either of these. Certainly the developed nations have changed substantially, but in many respects they have not changed much if at all.

      I get up in the morning, go to work from 8-5 every weekday morning for 40 hrs a week. Same as my dad did, and same as my kids will. How we do our work has changed, but the simple pattern of society in which we work to earn money to pay for housing, food, et al. has remained unchanged.

      In the bulk of the world, life is much closer akin to my grandfolks time. People work from sunrise to sunset to scratch out a living, and their sustenance, from the land. Nano technology is not going to dramatically change their lives. Drought or other climatic changes will be the key variable to their lives.

      We do indeed live in interesting times, but I do not think that our time is any more interesting on an individual level than any other time. We live in a time that has seen the average american progress steadily further from the basic compnents of survival. How many average americans would be able to fend for themselves in the "wild?" The "interesting" past of our American lives is when all the artificial walls separating us from basic needs come crashing down.

      Nanotechnology then does but attempt to fortify those walls and afford us protection from our fear of being without. Earlier times had the same fear, the difference being that they lived closer to their fear than we do.

        And they were right - they did. Not then, and not in the laser death ray way they thought back then, but now. I read a compelling article a while back (probably here) that proposed that the tech boom of the 90's was not the result of computer, the Internet or anything else. It was about lasers becomming cheap enough to be put in everything. Lasers are in millions of things. We don't even think about them - CD, DVD, fibre networks, SP/DIF..etc.

        The transformations don't happen until the price point comes down. Nanotech is more like the way people think about the Internet - it starts inexspensivley from the get go (wouldn't have without those cheap lasers though). Once the first practical molecular assemblers are created (assuming they can be) it will boom very very quickly.

      Lets separate what real nanotech offers from what nanotech does in SF stories.

      Firstly, look at some of the stories set now, written 50 years ago. How many of them have an even part way accurate description of, well, anything?

      So, when your talking about nanotech, what are you actually thinking of?

      What I'm thinking of is something that will be a bit like a cross between mechanical engineering and chemistry - make the various mechanical parts small so that they tend to operate in a chemicaly relevent length scale. That's the sort of thing that these micro-engines are.

      Think about biology for a moment, and about the sorts of biochemical reactions that go on in a living being. Those are the sort of things that nanotach can do. I do not believe that we will see a "Universal constructor" type device for many centuries, if ever.

      Note that the two examples that you give have been solved without the use of nano tech. Superconducting powerlines are in use in europe. They are unfortunatly only cost effective for short range (around 100 miles or so) high power transfers - but that's improving.
      The problem with fusion is not materials. You cannot get a material that will contain a fusion reaction - instead they use magnetic containment. And the problem is keeping the thing stable. I cannot see how nanotech devices would assist in this.

      So, in sumary, you are thinking of the effects of something, but I've no idea what.

      A friend and I were having a discussion about this a few months ago. We both love "technology", but I think I tend to overboard on the side of seeing it as the tool withi which all problems can be solved. My friend has a more cautious view. He suggested that eventually there will be a time when this stuff will probably result in many problems:

      -War (over who should use it and how it should be used.)
      -New nanotech based "diseases" caused by their proliferation
      -Political and ethical issues that no one can even dream of right now

      The usual stuff to be sure, but nonetheless the kind of thing that someone like me would never think about. I think you are correct in your assertion that society and governance will have trouble catching up. They are already having trouble with the Internet alone. (Think spam regulation)

      On another subtopic: I think that nanotech in it's current form is very much akin to the early days of computing when the first nixie tubes were being used as a display device. They displayed information in a very rudimentary fashion that still required human intervention to be interpreted to the common man.

      What I think will be interesting in the future of nanotech is when we can manipulate matter as we do pixels in today's 3d rendering engines. Think of it as rendering reality... with filters... and the ability to manipulate textures... colors... etc.

      I would suggest that all the algorithms we've been developing for 3D rendering will be the very fundamentals of matter manipulation software. Of course there are many other factors that we currently ignore in 3D that will be essential to real matter. (Don't want hollow object for one thing)

      Just imagine the possibility of applying encryption and compression algorithms on matter. :) You store the data model of your physical object and you discard the portions of the model that are repetitious.

      From the technical angle, it's going to be a lot of fun. From the societal angle it's going to be very tumultuous.

      Personally, I think that eventually waste dumps are going to become goldmines for discarded matter to use in the manufacturing of new materials. If I were interested in making money long term, I'd probably buy a few garbage dumps now and keep them in the family.

The reason why I didn't is that their press release doesn't make a lot of sense, and there's nothing more substantial on their site [bham.ac.uk] or in the video [research-tv.com]. This piece [icnetwork.co.uk] is better, but not much better, at least for the microengine-instead-of-battery applications to which people keep saying their developments apply.

    "These micro-engines have over 300 times more energy than an ordinary battery" is meaningless. If they mean total energy delivery over whatever time period you like, then microengines can beat batteries by a factor of a million trillion zillion, as long as you hook them up to a big enough fuel tank. In actual power capacity, though, microengines aren't anything special at all, yet.

    The aim is little turbines the size of a sugar cube that run from butane or propane or whatever, and have several watts of output power; prototypes of such things have been spinning for a while now. The microengines shown in the U of B release, though, are minuscule piston units which have power output in the microwatts, if that. Heck, the ones shown in the release don't even have generators attached to them, so their electrical output at the moment is zero!

    For your amusement: A reader also pointed this [indiatimes.com] out to me; it's a reprint of a piece on the subject from the British "Sun" tabloid, and it reads as if they took the U of B press release and put it through a Markov chain [san-francisco.ca.us] program, or something.

    Great. Now I can add my laptop and cell phone, along with nail clippers and wooden slupting tools, to list the of things you can be detained Airport Security guards can pull me out of line and strip search me down for...

    I've been saving this up for a moment like this:

    Ever since I heard of Unix
    I've always had a ball,
    From Berkeley up to Linux
    I must've run 'em all;
    But I ain't seen nothing like him
    On systems large or small
    That tired, squinting, blind kid
    Sure makes a mean sys call!

    He sits just like a statue,
    Like part of the machine,
    Feeling all the limits,
    Knows what signals mean,
    Hacks by intuition,
    His process never stalls,
    That tired, squinting, blind kid
    Sure makes a mean sys call!

    He's a Unix Wizard,
    I just can't get the gist
    A Unix wizard's
    Got such a mental twist.

    How do you think he does it?
    I don't know!
    What makes him so good?

    Ain't got no distractions,
    Don't hear no biffs or bells,
    Don't see no lights a flashin'
    Ignores his sense of smell,
    Patches running kernels
    Dumps no core at all,
    That tired, squinting, blind kid
    Sure makes a mean sys call!

    I thought I was
    The process table king,
    But I've just handed
    My root password to him.

    Even on my own hot boxes,
    His hacks can beat my best.
    The network leads him in,
    And he just does the rest.
    He's got crazy Finger servers
    Never will seg-fault...

    Sure makes a mean sys call!

    Unfortunately, you can't take flammable liquids like lighter fluid aboard aircraft, so it isn't going to help much on those long flights unless they change the regs. I don't see that hapening in the current security climate.

      You can't? I've never been stopped from taking my Zippo or Bic on board.

    About a year ago, Popular Science did an article on nanotech motors. They said that the biggest drawback of even the best Li-batteries is that no battery has even hit the 1% efficiency rating. Reasearchers hope that with these mini-engines, we may finally see power devices as small as a battery that can produce over 1% efficiency. I believe that 10% is their ultimate goal, although anything over 1% would still be worlds better than batteries. Granted, use in such devices as portable phones would actually mean that the micro engines would just be recharging the batteries, which would limit the overall efficiency to less than a 10th of a percent, but given other applications and better technology, such nano engines could replace Li-batteries in laptops and other high performance appliances. No more plugging your laptop into the wall, just go to the gas station and filler up ;) .
    • Surely they don't really mean batteries only have "1% efficiency" in terms of energy usage. I'm too lazy to look it up now, but I would bet that the process of charging and discharging a good battery would achieve 50% to 75% efficiency. IOW, you get up to 75% of the electrical energy back out that you put in. Otherwise, electric cars would be totally out of the question, and charging a 20W laptop would consume kilowatts of power.

      What they probably meant is that a battery of a given mass is only able to st

        Actually the LiIon and LiPolymer batteries casually achieve 98% storage efficiency. That's why a 68W battery, charging at 4Amps, is quite lukewarm. If the charging process would be so inefficient, the battery would be hot as hell itself.

  • The article [bham.ac.uk] about the micro engine was frustrating. "300 times more eneergy". Bah! 300 times more energy than a watch battery or a car battery? Obviously, they mean power but how much power? 300 times x? What's x?

    Also, since this thing consumes fuel, it might be helpful to compare power-to-weight ratios with the smallest gas engines widely available (e.g., model airplane engines).

    Thanks a lot, U Birmingham, for dumbing the article so far down that all it conveys is "oooohhh look, neat new thing".

  • The microengine are very small (thumbnail) sized combustion engines that drive a generator.

    I believe the 300x figure would be for electricity generated in a cubic inch... Though the article seems to actually trying to state that it would be based on cost, that the energy requirement for making the battery far exceeds the amount of electricity that comes out of the battery over it's entire life.

    So that these little engines would be very cheap to manufacture. And I need a little assurance that these aren'
  • Once again, the story has been posted on physicsweb [physicsweb.org] two days ago.

    The article is very light on the technical details of how lighter fluid will generate the energy, other than that the device be "a few millimetres wide". But the MSDS for Ronsonol Lighter Fluid [k12.ok.us] goes into quite a bit of detail:
