Cold Fusion 2009
April 19, 2009
years ago it appeared, for a moment, that all our energy problems could be
solved. It was the announcement of cold fusion - nuclear energy like that
which powers the sun - but at room temperature on a table top. It promised
to be cheap, limitless and clean. Cold fusion would end our dependence on
the Middle East and stop those greenhouse gases blamed for global warming.
It would change everything.
Treasure... and it's FREE
What does it feel like to suddenly understand everything? God's Debris isn’t the final answer to the Big Questions -- it might be the most compelling vision of reality you will ever read.... Still, God's Debris is emphatically not for everyone. Although there’s no sex or violence... (cont)...
Immediately, prestigious labs at MIT and
Caltech rushed to reproduce the experiment, but didn't get the same results
as Fleischmann and Pons.
The careers of Fleischmann and Pons were destroyed as quickly as a nuclear flash - names once linked to a Nobel Prize were forgotten by nearly everyone. And most of the scientific world today is happy to leave it that way.
"I'm still waiting for the water heaters. I'm still waiting for the thing that will produce heat on demand," Richard Garwin, one of the most respected physicists in the world, told Pelley.
In the 1950s, he helped design the most successful fusion experiment of all time: the hydrogen bomb.
"It was unfortunately, a very successful experiment," Garwin told Pelley.
Garwin was a critic of Martin Fleischmann back in 1989. And he has seen reports on the research that's been done since.
He thinks McKubre is mistaken.
Asked why, Garwin said, "I think probably he measures the input power wrong."
It's one of the most common criticisms of cold fusion experiments - that the amount of electricity going in and the heat coming out are simply mismeasured.
"It's possible, it is possible, that I have been mismeasuring energy for 20 years, but I think it extremely unlikely. A very large number of people have been making these measurements and measurements of current, voltage, temperature, resistance they're some of the simplest measurements that a physicist or a physical scientist will measure," McKubre said.
But there's another problem that critics point out: the experiments produce excess heat at best 70 percent of the time; it can take days or weeks for the excess heat to show up. And it's never the same amount of energy twice.
"I require that you be able to make one of these things, replicate it, put it here. It heats up the cup of tea. I'll drink the tea. Then you make me another cup of tea. And I'll drink that too. That's not it," Garwin said.
He told Pelley that for him to become a believer, the process would have to work 100 percent of the time.
But McKubre said, "Our critics often complain that we can't boil water to make tea. We could have, in fact, boiled 64 gallons of water and made 1,000 cups of tea, had we chosen to do so."
No one's sure why the experiments can't be consistently reproduced. McKubre thinks it has something to do with how the palladium is prepared. He's working with an Italian government lab called ENEA where some of the most reliable palladium is made.
With so many open questions, 60 Minutes wanted
to find out whether cold fusion is more than a tempest in a teapot. So 60
Minutes turned to an independent scientist, Rob Duncan, vice chancellor of
research at the University of Missouri and an expert in measuring energy.
"When we first called you and said 'We'd like you to look into cold fusion for 60 Minutes,' what did you think when you hung up the phone?" Pelley asked Duncan.
"I think my first reaction was something like, 'Well, hasn't that been debunked?'" he replied.
We asked Duncan to go with 60 Minutes to Israel, where a lab called Energetics Technologies has reported some of the biggest energy gains yet.
Duncan spent two days examining cold fusion experiments and investigating whether the measurements were accurate.
Asked what he thought when he left the Israeli lab, Duncan told Pelley, "I thought, 'Wow. They've done something very interesting here.'"
He crunched the numbers himself and searched for an explanation other than a nuclear effect. "I found that the work done was carefully done, and that the excess heat, as I see it now, is quite real," Duncan said.
Asked if was surprised that he'd hear himself saying that, Duncan told Pelley, "Very much. I never thought I'd say that."
And we've found that the Pentagon is saying it too. The Defense Advanced Research Projects Agency, known as DARPA, did its own analysis and 60 Minutes obtained an internal memo that concludes there is "no doubt that anomalous excess heat is produced in these experiments."
Asked if he feels vindicated after all these years, McKubre told Pelley with a smile, "I don't have any real need for vindication. I know what I've seen."
"That was a pretty big smile on your face though," Pelley pointed out.
"It's good. It's not bad. Certainly itís good," McKubre replied.
Now the Pentagon is funding more experiments at the naval research lab in Washington, D.C. and at McKubre's lab in California.
60 Minutes wondered what Richard Garwin would
think of the Defense Department's appraisal.
"The experiments leave 'no doubt that anomalous, excess heat is produced,'" Pelley told Garwin.
"Well, thatís a statement," Garwin said. "I am living proof that there's doubt. Now, they can say that there, that excess heat is being produced. But they can't say there's no doubt. All they can say is they don't doubt. But I doubt."
"If you ask me, is this going to have any impact on our energy policy, itís impossible to say, because we don't fundamentally understand the process yet. But to say, because we don't fundamentally understand the process and that's why we're not going to study it, is like saying, 'I'm too sick to go to the doctor,'" Duncan argued.
"You know, I wonder how you feel about going public endorsing this phenomenon on 60 Minutes when maybe 90 percent, I'm guessing, of your colleagues think that it's crackpot science?" Pelley asked.
"I certainly was among those 90 percent before I looked at the data. And I can see where theyíll be very concerned when they see this piece. All I have to say is: read the published results. Talk to the scientists. Never let anyone do your thinking for you," he replied.
There was one more scientist 60 Minutes wanted to find, a man who left America in disgrace and retired with his wife to the English countryside.
Martin Fleischmann, the man who announced cold fusion to the world, is hindered by years, diabetes, Parkinson's disease and maybe a little bitterness. At home, he pulled out an improved version of his experiment, something that he was working on when he was hounded out of science.
"When you hold that in your hand and you think back on what's happened these last 20 years, what do you think?" Pelley asked.
"A wasted opportunity," Fleischmann replied.
He thinks this way because it was discredited at the time.
He told Pelley he has two regrets: calling the nuclear effect "fusion," a name coined by a competitor, and having that news conference, something he says the University of Utah wanted.
"Now that you know that your experiments have been replicated and, and improved upon in labs all over the world I wonder, do you see a day when homes will be powered by these cells, when cars will be powered by these cells?" Pelley asked.
"I think so. It wouldnít take very long to implement this," Fleischman replied, laughing. "You make me feel that I should take a part in this?"
"I'm getting you interested again?" Pelley asked.
"Yes," Fleischmann replied, laughing. "The potential is exciting."
