But unlike oil and gas, hydrogen is not a fuel. It is a way of storing or transporting energy. You have to make it before you can use it -- generally by extracting hydrogen from fossil fuels, or by using electricity to split it from water.
How is hydrogen not a fuel? I always thought fuel was a substance that when it goes through a chemical reaction releases energy. While many fuels are burned, the process of generating energy in a fuel cell is still a chemical reaction.
Secondly, aren't there other fuels that have to be made before we can use them? Gasoline and diesel have to be refined -- it's not like we find them naturally in the ground.
So hydrogen is just a way of "storing and transporting energy". I thought the use of fuels was a way to "store and transport energy".
In 1968 Douglas Engelbart gave a presentation of the NLS/Augment system in San Francisco. It's quite amazing. It uses a three button mouse and pointer (called a bug). It also uses several buttons operated by the non-mouse hand in a chorded fashion to select and copy text.
Video conferencing, group collaboration, the hierarchical presentation and hiding of data, spatial representation of data, hyperlinking are all shown in the demo.
I first saw this in one of my computer science classes at Berkeley; we were all surprised at how much of what we think of as recent technology (last 10 years or so) actually existed in 1968.
NOTE: The video is rather long. The impatient (read: Slashdotters) might want to fast forward through parts.
...that Ferenhite 451 is comming. No more books. No more written records. Students will start using only computers...
At least then they would always have access to spellcheck. However, here is a simple mnemonic for remembering that pesky ie/ei thing:
It's I before E
Except after C
Or unless sounding like A
As in Neighbor or Weigh
Or unless it is
Either, neither, forfeit, seize, foreign, counterfeit,
Weird, science, sufficient, species, leisure, conscience, height
Or German in origin
Fahrenheit is clearly subject to the last condition using basic historical knowledge and therefore is EI. Speling is so simpul!
While the article kindly reminds us that Firewire runs at 400 Mbps, there is no mention of range. How much data can you transfer through the air before you start to cook things?
Having everything on your desk talk via wireless Firewire seems feasible. But is it possible to have an entire house run at 400 Mbps, walls, RF sources, and all?
Seems like this might be an 802.11g type deal with 54MB on paper and a much lower real life value.
Yes it does, but the advancement of consoles looks more like a staircase then a straight line.
Also remember that Moore's Law applies to the transistor count on chips and not the actual processing power (although the two are often closely related).
Especially in a major city like San Francisco, you've gotta have coordinated traffic lights or the streets will be a mess
Actually, the signal in question is out in the suburbs (it's in Pleasanton).
As for traffic being a mess in SF, most of the traffic signals in the city are "dumb" and operate on timers only. There is also no north/south freeway through SF (the Golden Gate Bridge dumps you on city streets). It should be noted that SF has one of the highest pedestrian fatality rates in the nation.
There is a plan to build a high speed train between San Francisco/Sacramento and LA/San Diego.
It is supposed to be on the November 2004 ballot, but with the current CA debt situation who knows if voters will go for it.
Senate Bill 1856: This bill authorizes a $9.95 billion general obligation bond for the November 2004 ballot. $9 billion would create the State's share of the construction costs for the San Francisco to Los Angeles segment of the high-speed train system as presented in the Authority's business plan. The remaining $950 million would be dedicated to feeder rail programs to the high-speed rail system.
I had a friend who taped the 10 episodes from season one and we watched it in a single 30 minute sitting. Each episode is only 3 minutes, so they seem more like a scene from a story rather than a complete story.
It is mostly action driven with very little dialog. I found it to be enjoyable. However, I think if I watched each 3 minute episode a week apart it wouldn't have been as good.
One of the main problems with OLEDs it that they begin to fade after 10,000 hrs or so. Any ideas on how long this panel lasts? The PR piece makes it sound like the only outstanding problems are making it "cheaper" and increasing its output per watt.
In the 1970's the gas tank on Ford Pintos could explode when rear ended. In the 2000's the gas tank on Ford Crown Victorias can explode when rear ended.
Your right though, it's not 1970 anymore. The difference, the Crown Victoria has a bigger gas tank. But people are still being killed due to poor design.
Because of incidents like this and poor quality ratings in general (from places like Consumer Reports) perhaps the negative image of Ford is not unfounded.
Postings about security updates are always useful, especially to those of us who have to support IE users. It's a lot easier than having to constantly hit F5 on the windowsupdate.microsoft.com page:)
According to this NY Times article...$200 million worth of instruments that had been built to be added in the later shuttle mission will also be left on the ground...
It also notes that a service mission costs around $500 million. If we have already invested 40% of the price of a service mission on parts we might want to consider actually using them.
The only other good route would be S.D. to LA to S.F...

Just because a fungal parasite is infesting the bee colonies, it doesn't rule out the possibility that EMF is impacting the bees' navigation.
Does anyone know if Guitar Hero can be played on a PS3?
I assume a PS2 controller to USB adapter would allow the guitar to be plugged in, but has anyone actually got it to work?

The new standard calls for 42v not 48.
It looks like there is the Toyota Crown Royal which uses 42v and a "new SUV from GM" that will use 42v as well. Source.

Now that voting problems have actually had a big enough affect on an election to probably change the outcome...

In SOVIET RUSSIA you know everything about credit cards.
In CAPITALIST AMERICA the credit cards know everything about YOU!

I guess I'll have to go third party on this election.
Good news for you! Nader running again. And all of you people said voting for a third party candidate had would have no impact...
