GE claim they can bring the price of hydrogen to $3 per kilogram, and cars that running on hydrogen are reporting mileage from 30~50 miles per kilogram depending on the manufacturers. At this ratio, the hydrogen is almost at the same price of the gas. The problem is infrastructure.
I remember single wall nanotubes are either metallic or semiconductive. It is pretty interesting to know how could they only grow metallic nanotubes or remove semiconductive nanotubes. Or actually they don't, and the electrons select metallic tubes automatically, but I highly doubt this approach because the electrons via metallic nannotubes and electrons via semiconductive nanotubes will arrive at different time. I am waiting for my friend who attend the meeting tell me the whole story.
The useful part of a CPU is mostly SiO2 with some metal and polycrystaline silicon and a small amount of doped single crystal silicon.
Now adays many of the SiO2 in those fancy CPUs has been replaced by SiLK and maybe MMSQ. SiLK is cross linked organic stuff, the real structure has not been revealed yet. MMSQ, IMHO, is a kind of silicone.
While the whole thing is a little more complicated. Ovshinsky was the first one to get patent on this area, and he opened a company named Ovonics. Then Ovonics created a company named Ovonyx with a cofounder of Micron. Ovonyx is focused on the Phase Change RAM while Ovonics keeps working on things like Fuel cell, Solar cell, batteries...
Gordon Moore of Intel was also one of the early researchers on the area of Phasse Change RAM. In 2000, Intel invested some big money into Ovonyx and get the license of Phase Change RAM from Ovonyx. Samsung licensed the Phase Change RAM from Ovonyx later.
how about a layer of salt water enclosed within two layers of Polycarbonate sheets. It should be able to hold the RF radiation while transparent. But my DVD rom looks really ugly...
The difference is buy selling the $150 computer, the Chinese company makes money, while by providing the $100 laptop, OLPC looses money, the other Chinese company makes money.
There are 5 billion people educated by their governments out there in our world, and they just hate what their government hate and love what their government love. Including 1 billion Chinese speaking Chinese.
The reality is after Beijing government ban zh.wikipedia.org, the zh.wikipedia.org has become a playground of anti-Beijing activists. NPOV has been damaged greatly since then. The Beijing government definitely shoot his own foot on this move.
the picture of hard drive looks familiar to me. I have seen some of them. One of my friends was analyzing why they fail several years ago.
And basically they reached two answers. Some of the companies have replace the halogen based flame retardants with phosphorus based flame retardants due to environmental reasons. Some of the phosphorus based flame retardants are phosphates. And the phosphates segregate out of the epoxy used to embed the die under certain heat and humidity conditions. When there are enough phosphate leached out, it shorts the leads of IC. If you are lucky, you can get the power leads short and the IC is on fire. So in short, the new flame retardant set the IC on fire. This condition happens in summer mostly because of the higher humidity.
And the second reason was that some of the IC makers have replaced the lead based solder with lead free solder due to environmental concern. Most lead free solders are tin rich. And tin grow whiskers. The tin whisker can short leads. Again, if you are lucky, you get power lines short and you get fire.
Yesterday a friend told me that the Sony battery was also short by whiskers. I didn't understand where comes the whiskers though.
Mozilla has been doing good in these areas IMHO. But what are benefits users and mozilla get from obeying these standards? What is the real W3C? Who in the W3C make the standards? Why should people listen to them? Do you consider they way IE rendering pages a de facto standard?
#2: Um... write better code. Code reviews. Smoketests. Purify. Seriously, that's what Computer Engineering's all about - writing robust and scalable code.
Does mozilla.org have enough people to do all of the work?
#3: Native look-and-feel. Support for the drag-and-drop methods of their respective OS'. Support for their native text rendering and printing facilities. Adoption of that OS' accessibility functionality.
Does that mean writing interface code in C++ or similar languages instead of xml and javascript?
#4: don't understand that question.
By saying "community", do you mean the mozilla user community or the linux distros communities?
Question #1: what is current standards? Question #2: how to make an uncrashable software? Question #3: how to integrate it with main OSes? Question #4: what is the relationship between community and most linux distros?
Wish #1, I hope they can make the memory footprint smaller. But I got 3G memory, and I don't really care.

That is 70 miles per kilogram. read http://www.greencarcongress.com/2005/10/hondas_mor e_pow.html and http://world.honda.com/FuelCell/

plastics conduct by big PI bond, water conducts by ions moving in water, ceramics conduct by motion of charged defects and ions.
Can I get a copy of duke nukem forever for this Christmas?
Firstly I bought a DSLR.
Several months later I became unhappy with the lens.
One month later I bought a heavy lens.
I change lenses a lot. And I've got nice pictures.
Several months later I found dust on the sensor.
I went to a clean room, used dry nitrogen to clean the sensor. :-p
I think the new stuff will become the "JIT" part for SpiderMonkey Mr. Brendan has been talking for years, if not ten years.
I,a Chinese wikipedia editor, will do the "censor".
Also E4X is ECMA-357

Lost laptop computers won't be news worthy. What a boring world it will be.
Correct!
Their welfare state makes America's look comprehensiveOf course.
- no state education,Lie, there is a 9-year compulsory education in China without tuition, you still need to pay some fee though.
no state healthcare,Lie. But most of the Private enterprise don't pay insurance.
no unemployment benefit.Lie. Do you mind a quick google?
You're on your own, pal.What do you expect? Rely on the party and government?
Private enterprise is common and becoming more so, and people have the right to own property.Is there anything wrong with private enterprise? Hasn't the free world been working hard to bring this into reality?
It's not communist, it's just got a very authoritarian government that calls itself communist.partially agree.

Bottom line, Chinese companies make money.

There are many pages protected in Chinese wikipedia.
The technology behind the PRAM has been developed 20 or 30 years. 2 more years is not too much.
