BOFFINS FROM the Rensselaer Polytechnic Institute (RPI), Purdue University, Oak Ridge National Laboratory (ORNL), and the Russian Academy of Science (RAS) have managed to replicate controversial cold fusion experiments.
A March 2002 an article in Science (Vol. 295, March 2002), indicated that boffins had managed to use bubble fusion successfully, but this data was questioned because it was made with imprecise instrumentation.
Now Physical Review E is publishing an article by the team of researchers stating that it has replicated and extended previous experimental results and this time has used the right instruments. Cold fusion is a bit of a holy grail in the science world because if it could be made to work, it could produce a lot of energy without having to have a large amount of energy to start it.
Scientists have managed to do it in the past, but it always required more energy to be put into it than could be taken out, which is defeating the point a bit. A press release going into the details can be found here. µ
It was the first time I'd ever seen the term, so I went and looked it up. Now I have a new word in my vocabulary, always a treat. Thanks!
I am curious that DARPA paid for an experiment where the sensors came from "Russia and RPI."
Very curious collaboration, that.
"Would it not be more correct to say that its a holy grail becuase of the efficency with which it releases energy? It really does not produce more energy than went into making up the atoms being fused.."
Actually, that's not the case here. The sonic waves required to compress the bubbles do not take as much energy as is produced, if I understand this correctly.
This should be a 1000 post thread by now if this is true. In essence, an unlimited energy source.
Of course, te niggling question is what the cost of deuterium is, and whether deuterium as well as tritium can be generated
Not really what one would call cold.
Wow, super cool. Free energy!
I stumbled into this on a computer news site....in the UK.
Any idea what the Max temp is on the Sun, I am sure it is way lower than this.....
The atoms are not fused, it's the nuclei -- and the extra energy comes from a small change in mass during the fusion, via E=mc2.
I am impressed. Hugh and series indeed!
I await the news and developments.
No, they also declared the Purdue experiment bunk. Of course, they could be wrong (I hope they are).
The temperature reading may be technically correct, but you need a little asterisk. The temperature they are talking about is only over very small volumes, and very short time frames. Hopefully, that's all they need, though.
That is correct with one addition, the released energy can go back into the production of more sound waves, and the excess energy can be captured.
In other words, once started, no more energy in needed to keep it going. (perpetual energy)
I always associated boffin with some kind of fusion.
"That is correct with one addition, the released energy can go back into the production of more sound waves, and the excess energy can be captured.

Well, perhaps. I find this story interesting, and will follow its progress. Time will tell if this has a practical application or is another interesting, but useless, experiment. I'm hopeful, but not convinced.
of course poor wording on my part, but that matter being converted to energy took energy to create. You cant create energy that is not there.
Yes, they were using electrochemistry and weren't even physicists.
Too good to be true???? maybe - but I still have a gut feeling that something happened then and there
But the matter you are destroying in the process was not created in an energy vaccume..
Only until you run out of deuterium in your machine.
