Normally when people agree with me on slashdot I worry but in this case I was glad to see that a few other people have formed the same opinion of this guys 'proof' as me. In other words the mans off his head and understands physics to a lesser extent than my dog (my dog doesn't come up with theories that imply that sound waves are created by gravity, you do the math). To be fair, by putting 'proved' in the quotes it deserves, I think the parent understands this.
Not necessarily a joke- this thing will eat an ungodly amount of electricity. I've visited JET (its predecessor)and they have a couple of massive flywheels (house sized) which they slowly spin up from grid current and then use as an extra supply when they're actually running the reactor. This is necessary to stop it browning out the surrounding area when it's at full load! We're a little way away from getting electricity OUT of this bad boy.
Ok, so back in the day an Xbox was cheap for what it was but these days? Buying PIII 733MHz, 128MB, 10 gig HDD's in bulk you can get them for £35-£40 (~65 dollars) making them, at most, half the price of an X box. No mod chipping required, bigger hard drive and a real P3 chip instead of the bastardised half celeron found in the X box.
The great thing about fossil fuels is the huge energy return in comparison to the energy required to extract the fuel in the first place. They also have a great energy density (i.e. lots of energy per unit volume of fuel). There are NO synthetic fuels which posess these properties. This is the huge problem.
Jesus. Is it really this easy? I don't own an ipod but if it's this simple and most of you ipod owners can't manage it without an article....never mind. On a totally unrelated note, does anyone want to swap their ipod for some of my magic beans?
There was a whole website devoted to illegal downloads of matrix 2 pre cinema release(I forget the full title- I wish i could forget the whole damn movie). It looked identical to the official site apart from the "download trailer" link was changed to "download movie". Those pirates truly are cheeky bastards.
Finally. "The future" is here! Space flight for the masses (the rich ones anyways).
I know, I know. I'm sure it's only a matter of time before the flying cars get here though:-)
Yeah, he hangs out with the sensible people.
I mean, come on. Is it really THAT big a deal if I (hmmm by 'I' I mean 'generic home user' obviously) install a pirate copy of XP, pirate copy of office, pirate copy of photoshop etc, etc? I know the code monkeys gotta eat but a slight drop in the rate at which gate's money mountain is growing? My heart bleeds. Companies will pay anyway 'cos they're afraid of the big, bad lawyers. Everybody's happy!
He wrote "Mostly Harmless" when he was pretty depressed. I read an article/interview (Maybe in "Salmon of doubt"?) where he said that he wanted to go back to the series one last time to put it to rest in a slightly more cheery way. He was going to do it after he finished the dirk gently novel he was working on when he died.
I never got this. Many religious people have told me that science and religion are not mutually exclusive but it has always appeared to me that they fundamentally are. Can someone explain it?
I thought it was intriging - it appeared that they had found a way to do small scale hot fusion and (not cold fusion - collapsing bubbles producing high temperatures and pressures in a room temperature medium). Unfortunately when the experiment was repeated with different detectors they didn't get a neutron count. This seems a bit dodgy- there is much debate between the various parties even now. Having personally experienced how tricky it is distinguising small neut counts from background i'm going to sit on the fence over this one until someone (or a couiple of people) repeats the experiment again. My gut feeling is that if the reactions were taking place as they claim they'd get a much bigger neutron signature but this is no place for feelings- we'll just have to wait and see I guess.
Oops you did say aneutronic. BUT I thought the whole point was that they were achieving Deuterium-Deuterium and/or Deuterium-Tritium fusion reactions at low energies?
D-T reaction
D + T 4He (3.5 MeV) + n (14.1 MeV)
D-D reaction
D + D T (1.01 MeV) + p (3.02 MeV) (50%)
D + D 3He (0.82 MeV) + n (2.45 MeV) (50%)
Or are they fusing something else? Am I missing something? Inquiring minds want to know! I restate my plea for a peer reviewed paper which presents reliable and reproducable scientific data in this area. I take offence at the fact that you claim that I am "resistant to the assault of
experimental evidence" when in fact there isn't any beyond a few deeply suspect temperature anomalies.
This isn't "cold" fusion. It's "hot" fusion.
It just uses direct electrostatic acceleration of the ions instead of the techiniques used in tokamaks (heating with current, neutral bean injection etc)
Trust me- I built one. According to my uni lab supervisor it was the coolest 2nd year project he'd seen in ~30 years! They're damn good fun- check out "farnsworth fusor" on wikipedia or google. I even got a neutron count out of mine on a couple of pure deuterium runs.
The thing about these fusors is that they work based on known physics principles and many people have repeatable results for them. Unlike cold fusion.
It may have been a real nuclear efect in your mind but we're concerned witg the real world, not your delusional fantasy.
No fast neutrons = no deuterium fusion
You can get fast neuts without a fusion reaction but you sure as hell can't have a fusion reaction with no fast neuts.
Give me a link to a peer-reviewed paper describing a reputable, repeatable experiment on cold fusion which showed a clear neutron reading above background and I'll strip naked and shout the praises of cold fusion from the roof tops.
Be quiet.
What do you base your "dead end road" assesment on? The fact that JET got break even? The fact that experts in the field belive that ITER is the next big step to a viable power reactor? The fact that it's based on solid physics and is actually working?
Cold fusion- you can't seriously think that it (or zero point energy for that matter) is a serious alternative to hot fusion? It's not even certain that there's an effect there to exploit! (putting it mildly...)
Let me guess, you're not a physicist?
People seem to be worried that google's diversifying too much and may overstretch themselves (*cough* Yahoo). I, however, think they have a better plan. You see they're huge enough now that when they start to do something, even if they only do it in a small way, EVERYBODY (other 'net companies that is) jump on the bandwagon.
Take the example of Gmail. It's still in beta- they haven't done a massive roll out and the cash invested (relativly speaking) is small. BUT because google _might_ be rolling out this crazy 1 gig email service every other free email provider and their uncle has to give out hundreds and hundreds of meg of free storage. So the net result is that google spends a tiny bit of money and everybody gets a shitload of email space more or less as a direct result.
Plus everybody loves google even more 'cause now they've got all this shiny storage thanks to them. All the kudos, none of the cost. It's great- I can't wait to find out what google thinks we should all get next.

I wish I had mod points. Nuclear power is the only way forward.
Thank you. That's probably the most useful thing I'll see all day.

Actually ~26% already know this and the other ~27% will find out. The rest didn't vote and are entirely responsible for the mess we're in now.

You're braver than me- after hearing Shatners um, unique, version of "Lucy in the sky with diamonds" you couldn't pay me to listen to his new stuff.

6 so far by my count. At least 6 that have admitted it. I mean, I didn't, did you? You'd have to be some kind of porno obsessed....ah SLASHDOT. I see.

As I said neutrons being detected doesn't necessarily mean that fusion is taking place BUT without the neutrons there definately isn't any fusion.

My friends "Sorry man, technically I don't even own my own shoes" was quicker and made the same point!
Powerful ceramic magnets are insanely cheap nowadays. I'm not sure why you think these plastic ones will be cheaper?
Its down. Slashdotted? Or has some public spirited citizen dealt with them?
