Did you calculate the weight of the battery pack? A Tesla Roadster has about 900 pounds of batteries, with this battery, you my need 2000 pounds of batteries to reach same "miles per charge" value.
From the numbers from the Toshiba news release, I calculated that the density is about 0.25 Mj/kg, which is a little bit higher than the NiMH batteries (0.22MJ/kg from wikipedia), but about half or less of lithium ion batteries (0.54-0.72 from wikipedia too). This is only an estimate.
The speed of people on this world consuming energy is at 10^13W scale. And the speed of the sun put energy onto this planet is at 10^17W or 10^16W scale. The amount of energy we used is way too small.
1, I think the GP means organic halogenated flame retardant in the epoxy and PCB used to package the chip.
2, I am not sure about Intel, but I know many fabs have stopped HF wet etching and use dry etching instead. Because dry etching is actually cheaper and faster.
It depends. As many people explained to you, the smaller gate opens/closes faster. But thinner interconnect has higher resistance and closer interconnect has higher capacitance. At current gate size, the speed of CPU is dominated by RC delay. So copper has been used to lower the resistance and low K materials has been used to lower the capacitance. Also, as the gate becomes smaller, the leakage become bigger due to tunneling effect, which makes the efficiency low, so high K materials has been used to insulate the gate from the silicon.
As you may have figure out now, the shrinking of line width doesn't absolutely mean higher speed and higher efficiency. But one thing for sure is that they can stuff more SRAM based cache in the CPU, which helps the "real life" speed a lot.
The real alcohol production in my mind is either from sugar cane or from cellulose, which is still relatively unknown and facing a lot of uncertainty.
The problem hindering all bio fuel is the low energy transform efficiency of photo synthesis reaction, the theoretical efficiency of photo synthesis is somewhere around 6~8%, because a lot of energy has been used to produce cellulose, instead of things we can use. The real efficiency is much lower than 1%. With requirement of sunshine, water, land and fertilizer, I don't consider current way of making alcohol can sustain. The cellulose alcohol on the other side, can use a lot of energy stored in the plants we can't use before.
Also we need to build a new pipeline system for the alcohol because alcohol can't use the pipeline built for oil. Alcohol absorb water and we get corrosion problems in our cars, at gas stations in the pipelines...
The bio diesel has the same photo synthesis efficiency problem. However the advantage of bio diesel is it is easy to make and can be integrated into the current infrastructure easily.
The battery, as long as we are still complaining the battery life of our cell phones and note book computers, the battery powered cars are rich people's toys. Also we need to reconstruct the power supply system to be able to feed energy to those battery powered cars. If you see your light dim when you turn on your blender or kitchen dispenser, how do you expect the power line can survive your battery powered car?
I believe biofuel (diesel and alcohol), battery/super capacitor and fuel cell will all get used in the (future) vehicles for some time at some degree. All of them have their own pros and cons. (You may figure out that all of them suck and all of them are promising at some points.) Technology will evolve and products will compete together. If we jump into a conclusion too fast, we are going to make mistakes. This is not a political or religion movement. It's not black and white. It's a war of green, war of dollars in the name of environment. The players in this game are trying to take money from our pockets and take their customers as hostage.
But pure mechanical polishing will produce a lot of dislocations, which will kill the efficiency of the photovoltaics. Also I am thinking if they keep the insulating layer (SmartCut or nanoCleave or ELTRAN wafer), they can use the wafer to make the type of photovoltaics with both N+ and P+ on the backside (I just can't remember the name) and the oxide as passive/antireflection layer. But are the handle wafers high quality wafers? For SIMOX wafer, I think the defects density maybe too high to be used in the photovoltaic area. Correct me if I am wrong.

No, you can't. The real story maybe something like this, 2 hours of driving, then find a place to charge, then power grid down due to high current.

But Chinese people like to use such format to present ancient poems, titles and etc.
But they read the same characters. Your data are about pronunciations.
Agree, I also think the W3C has separated themselves from the real world, they don't know what the web designers/developers want at all.
I think the native support of SVG in IE is impossible. VML(http://www.w3.org/TR/NOTE-VML) is already there.

No, it's not at the time I check the webpage. So based on your logic, it is a failure.
who gave you right to change my search engine setting?

And there are a whole bunch of developers not on Mozilla.org payroll.
I consider it is more popular than Azureus.
But if some one from Dell or HP claim he/she is from Asus and Apple is going to release a tablet...
1, how big is the impact of this bug? As far as I know, people barely do inter-volume move.
2, does the time machine thing bring the disappeared directory back?

What do you want to do with the hydrogen you make from the Ga/Al? Transfer them to electronic power via a fuel cell?

Browser compatibility of those javascript(s) and jscript is a nightmare.
So what do they do with SOI wafers? Remove the whole buried oxide layer by CMP?
