Overall, electric cars still produce less CO2 than today's hybrids, even when the power is generated from fossil fuels.
No.
"...Coal-based electricity leads to CO2 emissions nearly as high as for a gasoline-powered car! Yet hydropower results in dramatically lower CO2 emissions. If you want to make an impact on CO2 emissions with your next car purchase, you need to know how the electricity in your region is generated before making your choice. And if in doubt, the best advice is once again to go hybrid, as we indicated in the last issue of the Leaf."
Unless your electricity is generated in a way that doesn't damage the environment you are simply moving the pollution from your car to the power station.
Yes - an electric car run from coal-produced electricity produces about the same amount of pollution over it's lifetime as a normal car -

Are you kidding? That's one of many ridiculous things in that episode, but it's not even close to the most ridiculous thing in the episode.
When Starbuck finds the downed Cylon fighter, it has a hole by it's "eye" where she shot it. Then she gets in it, and plugs the hole with some cloth to keep the outside environment out.
Then she flies it into space. With some cloth plugging a hole in the ship.
That episode was already full of to many happy coincidences. A stereotypical "she's being pulled towards a cliff!" bit. The fact that the cylon fighter was somehow still intact. And it had been killed, but was still flyable. And, like you mentioned, that it just happened to be nicely sized for a human. That she could also outmanuever another good pilot in it. And frankly, it was a bit surprising to find that there was a convenient human-sized hatch she could open on the bottom of the ship. The "we can't jump until we kill the fighter!" thing at the end, despite the fact that the in the first episode all they ever did was jump when being attacked. The old "no one can ever be rescued until the absolute last minute" bit. And where did she write "Starbuck" on the wings of the fighter, and what the heck did she use to write it?...
But plugging a hole with some cloth to form a vacuum seal...come ON.

I don't think this is the case.
I don't recall the reference, but I've read that the ideal way to tell when a NiMH battery is fully charged is to measure it's internal temperature. This way you can pump it full of juice very quickly, but know exactly when to stop charging. I've read that traditional fast chargers slightly overcharge the NiMH battery because it's not until there's a voltage drop that they know to stop charging (which marginally degrades battery life, but not enough that you care) but temperature based charging is more ideal.
Actually...if you were really desperate to save money (yet *needed* to use your computer), these might be useful - you put your winter jacket on, and these could keep your fingers warm for typing..:-)
(Admittedly, it does seem like being cold to save money on heat then running a computer might not truly be economical...)
"AT&T has twice lowered the price of its DSL service and now offers its 1.5Mbps service for $12.99 for the first year."
It reads like ana AT&T add. No one (on slashdot) gives a rats ass what they charge for their "introductory period". Only their normal, non-introductory rate is what we care about. What's next, "They've lowered their rate to free for the first month! So obviously, by not mentioning what it actually costs, it's cheaper!"
"There is a married woman in my guild who is cheating on her husband with someone she met in my WoW guild. I feel really bad for the guy. It's not all roses."
Ooooooh, that's the worst diss ever! Can't you just see it now?
Girl: Who's that Tim guy? Is he single?
Friend: Yeah, but he's kind of a loser. Girl: Why?
Friend: Well...let's just say his last wife left him for a guy she met online in a role-playing game. Girl: Ooooh.

How long is it going to take people who write articles to get it?
What's happening with the new dvd format? I don't care. Almost no one who buys a PS3 cares about the blu-ray thing. Really. All we want to know about is the game system.
I'm not sure if they publish these articles to try to create hype about the blu-ray format and associate it with the "cool" Playstation, or if they get published because Sony genuinely believes that anyone cares.
Isn't everyone else getting a little tired of this chicken little stuff? First it's "OMG, All the programming jobs are being outsourced!" then it's "OMG, there aren't enough computer science majors!".
It can't be both that the programming field is in danger because we're outsourcing all our programming work, leading to no jobs for programmers, AND be that we're in danger of not having enough new programmers.
...is that different headphones have different volumes at the same power output. One of the really cool things about the high output of the iPod is that you can hook up higher quality headphones to them and it's still powerful enough to drive them. For example, my BeyerDynamic 250-80's have 80 ohms of resistance vs. the about 40ohms for the standard iPod earbuds. I have to turn the "volume" up higher on my iPod to reach the same volume with my headphones compared to the earbuds, but it's still able to drive them, which is really cool. If you read head-fi.com, you'll find that some people actually buy portable headphone amps so they can drive their high-resistance headphones.
I think it would be really cool if my iPod could tell me the decibel level that I'm playing my headphones at. But you'd need some sort of extra interface between the headphones and the player, and possibly some sort of microphone in the headphones, to be able to do that.

1. If you're already running WindowsXP with service pack 2, and you haven't turned off the firewall (it's on by default), then as long as the very first thing you do with your computer when you connect it to the internet is to download your windows updates, you're fine. (You can check which version of windows you have by going to the Start menu, then clicking "Run...", then typing in winver. A dialog should pop up, and the line that starts with "Version 5.1..." should say "Service Pack 2" at the end. If it doesn't, then you don't have service pack 2.)
3. If you have a non-XP version of windows, you should be behind some sort of firewall. If you have broadband access at home, and connect through a router, that should be fine. Otherwise, perhaps you could start your computer in "Safe mode with networking" (I believe you hit F8 while your computer is booting up, then it will prompt you to choose how you want to start your computer). This might avoid starting up most of those vulnerable services that get attached, so you might be safe. I haven't tried this though, so I have no idea if this would actually work.

No matter how much you use the words "simply" and "just" to describe it, having to constantly buy and pour more fuel into stuff is more work than plugging it in.
There certainly are a lot of fuel cell fans here, and the "coolness" factor always seems to keep them from thinking about the real pain of having to use fuel cells.
Think about the days when you had to buy new alkaline batteries for everything that didn't plug in. You were always buying new batteries. Your batteries would run out, and you would suddenly realize you don't have any extras. You would realize you only had the wrong size batteries. You would realize you forgot to bring extra batteries with you. Remember how much it cost to constantly be buying new batteries?
And can you imagine something like cell phones, which would undoubtedly take their own specific size of fuel cell. Can you imagine having to keep 50 replacement fuel cells around when your battery runs out? Having 50 different sizes of fuel cells?
A rechargable battery has one drawback - it takes time to recharge. But it has a lot of pluses - you can recharge it practically anywhere in your country, as everywhere has the same, standard power outlets. You can recharge it in your home, at a hotel, at your friends house, hell - with a converter you can recharge stuff in your car! It recharges very cheaply. Recharging it is a low-environmental impact operation - *relatively* little pollution is created by the power plant, and there's nothing to throw away.
The biggest two conveniences for me are that 1. I don't have to do much to recharge - plug it in and it does it's thing, and 2. I can do it completely at home, or most anywhere I go.
There's 1 reason why companies want to develop these fuel cells - they want to force you to pay them over and over again for their fuel cells, rather than you being able to cheaply and conveniently recharge your stuff at home where they don't make any money off you.
