U.S. Will Give Cold Fusion Second Look, After 15 Years

Fairy tales can come true

They can happen to you

When you're so hard up

You're compelled to make do

Does this mean that the decree that was issued saying that cold fusion could not work may be repealed?

With HYBRID cars getting 50-60 mpg, their batteries getting cheaper and cheaper (which will also help electric car sales), and FUEL CELLS coming online soon, the AY-RABS will be trying to sell their sand soon!

The new sound of fusion
Business Standard, India - Mar 17, 2004

“Cold fusion”, or tabletop fusion, is one subject on which the scientific community is violently divided.

Some scientists maintain that it is impossible; others say it’s possible and a chosen few have laid their reputations on the line by claiming to have achieved it.

One of those few is Rusi Talyarkhan, professor of nuclear engineering at Purdue University. In 2002, he led a team of Russo-American researchers who claimed success in a paper published in Science journal.

That initial result met with scepticism. But Talyarkhan’s team have done a more refined version of the experiment that, they claim, has reproduced and confirmed the results. The details will be published soon.

In 1989, a Franco-American combination of Stanley Pons and Martin Fleischman claimed to have achieved cold fusion at Utah University. Their results were discredited and, eventually, the two were even accused of deliberate fraud. It was a simple chemical reaction rather than nuclear fusion.

The Purdue team used a radically new method. First, they took a bowl of liquid acetone doped with a hydrogen isotope called deuterium, which has an extra neutron. This liquid was bombarded with fast-moving neutrons (electrically neutral particles). That created cavities, bubbles in lay terms. Then, the acetone was bombarded with ultrasound.

The bubbles trapped the ultrasound energy to go through a process of expansion and contraction, eventually, collapsing with great force. The energy released from the collapse raises the temperature, causing flashes of light.

The technique of sono-luminescence, or creating light through sound, is established and well-known and nobody’s disputing this effect.

But the Purdue team claims that fusion occurs and the deuterium changes to tritium (another isotope of hydrogen with more neutrons) with the release of gamma rays. Albeit confined to small spaces, sun-like conditions of temperature and pressure are created within the bubbles.

The techniques used will clarify many questions. It reduces the cost of creating neutrons by orders of magnitude. The high temperature-pressure gradients may be used to produce diamonds and other exotic materials. But did the experiments create fusion? The jury’s out.

cold fusion will not work, until someone makes it work. Until then, its a fantasy. =o)

I was talking to Alan Cicconi of AC Propulsion a couple of years ago. He's not sure that hybrid cars are at the present time such a big advantage over conventional cars. He says if you made a lightweight car with a small gasline engine, aerodynamic streamlining and high pressure tires you could easily match the mileage of the Japanese hybrids (which in truth don't get the mileage advertised anyway).

Where's that "Oh, no...not this sh*t again" guy when you need him?

[Kozak]

Can't wait till I can have one of these for home use....

[neverdem]

LOL

[Irishguy]

okay it might be wishful thinking...but i would like to see the next opec meeting once this is sorted!!!!

you can see the saudis telling their people 'hey you mob, yes you who have only read 1 book in your life, we are poor again...'

I am reminded that when early trains first achieved moderate speeds around 40 - 50 miles per hour, people were convinced it would be unhealthy for humans.

Folks, there's hardly been a discovery in human history that wasn't said impossible before it was proven a reality.

I'm not sure what compels people to trash efforts to find new discoveries, but it seems to be a whole force of nature all it's own.

I'm content to sit back and enjoy the show. Nothing ventured, nothing gained. Go for it!

My Honda Insight has been getting 61.3 mpg over the last two years. While it's true you might be able to get a straight gasoline powered car to turn out that kind of milage, driving it would not be pleasant. The hybrids manage to perform like normal cars, while getting outstanding mileage.

Wow, I gotta admit, there's a big reason why one should never look for science in popular press; they leap all over the place because usually they have no idea what the heck they're talking about.

And one question that desperately needs to be asked; even assuming that everything was correct with cold fusion, would it be possible to recover even 60% of the energy required to gather all the materials used in the experiment?

I'm wishing that these guys actually prove themselves and provide a great energy source. But then again, if wishes were ponies, every lawn would be green.

I had this very same issue in mind today when I saw a baby bottle!
