850 microns is 0.85mm. Regular sheet metal often comes in thicknesses like that - house roofing for example. In Australia a 5 cent piece is probably not far off.
The core of any chip might be silicon, but that's of the order 100mm square. There is an awfull lot of other metal, plasics, ink, paint, laquer, lubrication etc that makes up the rest of the computer. Many of those things are "molecular".
Here in WA, the breathalysers are often hidden in a quiet corner or the toilets. I couldnt say what percentage have the breath testers, but at a guess I'd say 30% of the bars I've been to.
It is the person using the machine that is supposed to decide whether it's a good idea or not.
The point is, a person affected by alcohol can often be unable to make those decisions.
How many people would be hurt by not being able to drive drunk? I dont know, but I'm willing to bet it would be far less than are hurt by drunken drivers.
I think you're getting too caught up on the "ignition = fire" comparison.
The sun is often referred to as a "fireball" or "burning", yet it is just "chain fusion". Ignition is quite a suitable name for this intense reaction, regardless of whether it is chemical or nuclear.
800x600 tends to loose alot of gaming real-estate. HUD's arent usually vector gaphics - at low resolutions they get large and annoying. 1024x768 is pretty good though.
IANAPETAA, but from an animal rights perspective remotely operated hunting is pretty lame:
1) You cant check/fishish off your prey 2) You cant clean up your prey
Both of these items would require a separate live operator to attention, but might not be effective. The process of safely locking out the gun before inspection would delay #1 and 2.
As the other child poster has stated, AC is mainly used because of the easy of use of transformers.
However, High Voltage DC actually performs better because you no longer have skin effects on the cable (apparant reduced resistance), and you dont get eddy losses. The hard part is generating the high voltage DC - but modern switching electronics has solved that at quite high efficiencies.
From what I've heard, the Trans Tasman power feed (Australian Mainland underwater -> Tasmania) is actually high voltage DC for efficienty reasons.
The main limitations on electic motors is heat - the wires will melt once you start pushing too much power.
With more conductive wires, you can get higher currents and thus higher power for the same size motor. Losses will be about the same becasue you'll just scale your motors to a suitable heat level again.
Higher power/weight ratios will make everything else that uses them lighter and more efficient.
Try it without the @Home bit. The whole point of this article is that simplified graphical front ends are good, which is what you are seeing with Asterisk@Home.

There's one problem with bottom-top airflow for home PC's. the bottom is where all of the dust settles on desks/floors etc.

RTFA, this is not a rebreather. Rebreathers are still limited by the main oxygen supply.
This unit extracts dissolved air from the water, so the limit is purely how many batteries you can carry.
Uhh...

I've definitely seen a couple of these. The one I recall had an SD slot for it's main (or only) storage.
Same here.
Im betting that if my floor were cleaned every day though, the dirt (dog hair) wouldnt have time to spread to the edges.

A whole car being recycled after just 100,000km? Absurd!

So you're saying we wont be navigating to the moon on one, but we can watch a movie on the way? Sounds good to me.
Good ideas. I'd mod you up if you I had the points.
Seeing the location depicted so accurately, I have only one fear...
Telefrags.
gold!

Why is neutron radiation so dangerous? By definition neutrons dont interact very much with normal matter - it's only chance that they colide.
I would have thought alpha/beta sources were the worst, especially at close range.
There might have computers, but they are not PC's. There is a huge difference.
Im sure the watermellon wasn't too thrilled with the process either.
It's a different market. WiMax is last mile, WiFi is hotspot.
Your house or local cafe might be conneted via WiMax to the ISP, and then there's be a WiFi AP transmitting that around the local area.

If you can get the signal into your eyes or ears, it can be recorded.
Then they're not really an "Internet" service provider are they....more like a "World Wide Web" service provider.
