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."
That thing sure is sensitive to tilt. A minor gravitational fluctuation sets it off.
Where is the quarter slot?
Trolling is a art,
"Rows and columns of tiny nano-pinball games" That sounds like I'm hallucinating quite badly.
"Electostatic actuation" - now maybe they could drive the music for it through nano-elctrostatic speakers:
"He's a nano wizard
There's got to be a spin
A nano wizard
S'got monocrystalline"
Esteem isn't a zero sum game
Now nano sized soldiers will have equipment to perfect their hand eye coordination before they launch their attack on mankind.
You are so going to be turning off your cell phone at the gas station now!
Oh, say does that Star-Spangled Banner entwine / The myrtle of Venus with Bacchus's vine?
When I tried to watch the film, I got this javascript "error":
There seems to be a problem with your system. Browser not Microsoft Internet Explorer
That's a problem?
We'll find WMD's in Iraq as soon as we plant them there.
Berkeley has been working on mini and micro rotary engines for a little while now. Rotaries are really better for this application as they have less moving parts. Their mini rotary engine is about the size of a penny while their micro rotary engine has a rotor of size 1mm! Rotaries have no valves which makes them much easier to produce at this size.

"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 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 program, or something.
It's good to know that alcoholism in the press is alive and well.
And a new record for the fastest slashdotting of a University website... Insert obligatory joke about Nanoseconds here.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
"These micro-engines have over 300 times more energy than an ordinary battery and are much lighter and smaller."
So a cellphone that needs a daily charging will now need a refill once a year?
I would wager that this claim carries a degree of exaggeration.

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.
If brevity is the soul of wit, then how does one explain Twitter?
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...
That tired, squinting, blind kid
Sure makes a mean sys call!
