They're in different markets nowadays. If your ripped the air con, the leather/wood trim, the sat nav and the other crap out the jag would be a damn sight quicker off the line than it is - it does have 350+hp and is made mainly of aluminium. Jag don't make sports cars anymore, they make fat executive cars. To be fair to the dude his comparison is that, essentially, a ferrari is much faster.
I agree with you on the 'high end' tuning front btw. I had a 15 year old supra turbo (bought for £600, ~$1100!) with no mods apart from an air filter and a less restrictive exhaust that'd eat that new jag alive.

To be honest, I think the reason that many people in our '1st world' society don't understand computers or know how to fix them when they go wrong is because they're lazy. People know that tech support (whether it's a department, a friend or a family memeber) is only a call away so as soon as anything goes wrong they reach for the phone. If this wasn't an option they'd be forced to spend a little of their own time working things out.
In my experience many people are also scared that they'll 'break something' and are unwilling to experiment.
"Sure, we can do it, cheap ass PC and an off the shelf light gun hacked into a paint sprayer. We'll use the GIMP to keep software costs down. Lets call it a grand, there's no way it'll cost us more than a couple of hundred in parts."
What the hell is this story doing here, in the science section? This is supposed to be news for nerds, I mean, come on. I can just about let stories like this slide when I read them in the newspaper (with the requisite amount of muttering darkly to myself) but seeing them here just makes me worry that truly nobody related to the media understands science at all. Some guy deciding he is electricity sensitive and shelling out $1000(!) for a device which 'cleans' his electricity is not news and it sure as hell isn't science.

Actually, I'm not sure you're exactly correct. Ever caught a ball somebody threw to you? That's some hardcore calculus right there. Just because you're not aware that your brain is crunching numbers doesn't mean that it isn't. In fact, at a basic level, I guess that imagination is just some rapid number crunching.
Often I have read an 'ask slashdot' question and thought that it was pretty stupid. Often they could be answered with 10 seconds worth of google searching. This one however takes the prize for dumbest question I have EVER seen. "So guys, we finally have a method of seamlessly communicating with every country in the world, how do you feel about breaking it? I mean, wouldn't it be great if I could only see US sites easily?"
My bottom of the range Nokia phone cost me £20 sterling, I bought it because it was the cheapest I could find. It has number blocking - I thought they all did! Writing your own number blocking software just seems like insane overkill.
First off- a disclaimer: I'm a physicist but solid state is not really my area. However, that said, the explanation presented for how the coulomb barrier is overcome seems deeply flawed.
/PI'm on firmer ground with the later bits (I'm a nuke physicist) so I fell more confident saying that the section explaing why no gamma radiation is observed is just plain wrong. Of course, it could be correct and it's just our understanding of physics that's flawed- make your own decision!
Actually, no. If you pull two deuterium nuclei together you get Helium-3 and a neut (50% of the time) or Tritium and a proton (50% of the time). So, half of your reactions produce a neutron. The reaction you present, deuterium+deuterium->helium is actually VERY unlikely (basically impossible under normal conditions due to parity concerns). Even if, due to some phenomenon unknown to current physics, he was exclusively doing this reaction there would be a flux of high energy gamma rays which would be easily detectable.
It is important to note that the cold fusion advocates claimed for a long time to be detecting excess neutrons and only switched to this new 'it must be D-D->He reactions' when people pointed out that their neutron detection methodology was badly flawed.
Actually, I'd count myself as a scientist (a nuclear physicist to be specific). Do you have a link to a paper by these groups? Many, if not all, of the 'cold fusion works' claims fall down upon close scrutiny. Measuring very small neutron fluxes is a very, very difficult thing to do accurately. Indeed the cold fusion lobby has now moved on to claiming that there is a new form of neutron free, D-D fusion taking place which explains the lack of neuts. The other indicator, small temperature rises, is also very difficult to monitor.
Before jumping all over me you should carefully consider what is being claimed here. Saying "We did this experiment and there seems to be a an anomolous source of heat, which we cannot explain" is very different to saying "We did an experiment which demonstrated a new form of fusion, which has never been seen before and can solve the worlds energy problems!"
You could power your house off 235 fission (hey, we do with power plants), possibly even light your house via the glow discharge around a reactor but some people suggest that giving every house a big lump of uranium may not be the most sensible thing to do. So, what prevents us doing this is health, politics and efficiency concerns.
What prevents us using cold fusion is the fact that it doesn't work and has never worked!
High enrichment uranium (i.e. high in 235 - normally >90%) is weapons grade. So, basically, yes. However 235's also the bit that gives us power in power plants so it's not quite that simple!
A company press release explains that, in brief, "cold" fusion involves the fusion of two nuclei of deuterium or heavy hydrogen into a single helium atom, accompanied only by a burst of heat. Unlike "thermonuclear hot fusion" that requires the plasma-inducing inferno temperatures of the sun or a hydrogen bomb, solid-state fusion reactions can be produced at normal temperatures in certain hydrogen-loving metals without unleashing hot fusion's dangerous radiation.
Genius. They can't detect any excess neutrons so obviously there's a new, radiation free, type of D-D fusion going on.
He might have balls but that doesn't mean that he's not full of it. This is no more than a cynical attempt by this company to aquire venture funding. People have not ignored his 'science'; they have tested it, found that there is nothing in it and moved on.

Wanna buy a bridge? Or some 'soon to be patented' x-ray glasses? No such thing as free energy I'm afraid.
Anyone have a better link? Are they just scrolling through all the possible keys or what?
Wow, those naming agency guys come across as total pricks don't they?

Works just fine in my Mozilla.
That's the funniest post I've seen in a long time.
Forty years of darkness. Earthquakes, volcanoes...
The dead rising from the grave.
Human sacrifice, dogs and cats living together - mass hysteria.
Gnome and KDE together.....
What? So your car's at a 60 degree angle to the curb?
The driver. Just like if you plow into the back of someone at speed with your cruise control enabled.
In my experience many people are also scared that they'll 'break something' and are unwilling to experiment.
4 grand for that? I wouldn't classify that as 'ethical'!

I wouldn't call this post a troll. My first thought when I read this 'science' story was: "What a load of old bollocks"

Yes, Magnox too. In these the 0.7% or so of 235 found in natural (un-enriched) uranium is the important bit.
