Nanotech Pinball and Miniature Engines

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. Further information at Research-TV including photos and a film."

    Given that this is just another "Look that we can do now with interesting molecules!" thread, I suggest a side discussion:

    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.

      The change is not a matter of fact, it's a matter of perception. Essentially, nothing changed in this world during the last 14 or so billion years. After the laws of nature formed, nothing ever changed and I don't expect any changes for another 10^N years, until protons start decaying. Even talking about human life, knowing the history of technology well, one may argue that nothing really changed. Yeah, there have been fast food joints in Babylon (honest) and may be your grand-grand-...-grandfather was flipping the Babylonian analogue of burgers there (I don't imply here that you work in McDonalds).

      The problem is that unless we both agree about what constitutes significant change and what doesn't, any discussion on that topic is pointless. But I can only pity you for your 9-5 work pattern. I, on the other hand, am basically free to do what I am interested in. I don't have to work much, because one year of work (in relatively undeveloped Russia) is enough to support me very well for the next 1-2 years. I have access to a large fraction of human knowledge. I live in good environment, with sufficiently high quality of life, nice people around me (now it's not Russia), etc.
      Note: all that is not because I inherited a fortune or won it in a lottery.

      Is this enough of a change for you? They say that change can only come to you from within and I can see how true it is. Unless you change the way you live, nothing will happen. You are right, even when advanced nanotech will become reality, some people will probably not notice that and continue working 9-5, while others will become posthumans. :)

      And don't push your working philosophy on your kids. Instead help them become creative, intellegent, inquisitive and free people.

    Or how about when nanotech gets smaller then 1nm, are we going to have to the change that name too?

    Given that atoms are on the order of 0.1 to 0.3 nm and given the strong limitations imposed by nuclear physics (particularly the strong force), I don't think there is much risk.

    "Lasers were once seen as the technology that would transform the world."

    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.
