Promoter Andrea Rossi’s most recent test of his “energy catalyzer” failed to demonstrate the production of excess heat.

On Oct. 7, “the ‘E-cat’ invented by Andrea Rossi ran in a completely stable self-sustained mode for over three hours,” journalist Mats Lewan of Ny Teknik wrote.

According to Lewan, Rossi’s device released an average of 2.5 kilowatts of heat in 3.5 hours. This amounts to 31.5 megaJoules of energy.

However, Rossi heated the device with 2.7 kilowatts of electricity for four hours in advance. This amounts to 38.88 megaJoules of energy. He also heated the device during the phase which Lewan called “self-sustaining.” The input was 115 Watts for 3.5 hours. That’s 1.44 megaJoules of energy.

Let’s do the math of the total energy input versus energy output: (38.88 + 1.44) – 31.5 = 8.82.

That’s a total energy loss of 8.82 MJ during a 7.5-hour period*. In other words, Rossi has demonstrated a water heater that is 78 percent efficient. This is inconsistent with his claims of having a device that produces substantial amounts of excess heat in comparison to input energy.

On Oct. 7, New Energy Times asked Lewan how he justified his and Rossi’s implication that the Oct. 6 experiment showed a net energy gain, as well as their claim that the device was self-sustaining.

“I don’t believe I claimed anything at all,” Lewan wrote. “And I don’t think I reported a net energy gain. I only reported the energy developed during self- sustained mode.”

These are glaring inconsistencies.

Furthermore, in his technical report, Lewan ignores the input energy from the first four-hour warm-up period.

“The E-cat was considered to be completely operating only after reaching self-sustained mode,” he wrote.

Lewan’s and Rossi’s choice to ignore the input energy from the four-hour warm-up period is like saying a sailplane can fly without power, so long as it is first carried aloft by a tow plane.

* Minor radiative losses are not included in this rough calculation.

Excerpt:

Surprisingly enough, Rossi’s most severe critic is Steven Krivit, editor of the New Energy Times. Krivit has had years of experience at looking at all sorts cold fusion devices which have been claimed to produce power. His team have carried out a very thorough analysis of Rossi’s demonstrations and they have their doubts.

“According to my analysis, his claim has no scientific credibility,” Krivit told Wired.co.uk. The device he claimed to heat a factory in Bondeno seems to exist only on paper.”

Krivit’s analysis looks at the amount of steam that actually comes out of the device and the way it is measured. He concludes that the E-Cat does not have nearly the output he suggests, and may not even be producing excess energy.

Krivit’s answer to the question of whether Rossi’s demonstrations support his claims is: “Definitely no.”

There is some irony at work here: we apparently have a number of mainstream scientists backing an outlandish project which investors are putting money into, while the most vocal critic comes from the world of cold fusion.

Who’s right? The only way to find out will be to watch out for what Rossi does later this month.

NASA has nothing to say about Andrea Rossi’s claim that he has a relationship with NASA. Rossi is an Italian promoter who says he can produce commercially practical levels of LENR-based heat.

A source, who asked to remain anonymous, told New Energy Times that, on Sept. 5 and 6, a team comprising representatives from an investment group and NASA visited Rossi’s showroom in Bologna, Italy. The team went there with an explicit agreement about test parameters and opportunities to observe and evaluate Rossi’s claims. The team members did not observe any positive results.

The Sept. 5 test was inconclusive because Rossi’s device sprang a plumbing leak. The Sept. 6 test was inconclusive because there was no outflow of steam or water.

However, when reporter Mats Lewan from Ny Teknik showed up the next day, Rossi’s device produced an outflow of steam and water. But by then, the NASA observers had gone.

On Sept. 14, Lewan wrote that he observed Rossi’s “one megawatt [power] plant” and that the plant “is now being shipped to the United States.” The same day, Lewan wrote that he observed Rossi’s device producing excess heat without external energy input. Lewan produced and published a scientific-appearing technical report on behalf of Rossi.

The tests on Sept. 5, 6 and 7 were Rossi’s eighth, ninth and 10th attempts to show proof of his concept.

On Sept. 15, New Energy Times asked Dennis Bushnell, chief scientist at NASA’s Langley Research Center in Hampton, Virginia, whether he attended the Sept. 5 and 6 Rossi tests.

“We can’t discuss anything about that,” Bushnell said.

On Sept. 23, New Energy Times asked Jim Dunn, the former director of the NASA Northeast Regional Technology Transfer Center, whether he attended the Sept. 5 and 6 Rossi tests.

“You know I can’t answer that,” Dunn wrote. “All I can say is that I was ‘out of the country.’ The rest is up to your imagination.”

On Sept. 28, New Energy Times published a blog article saying that NASA engineers did not observe any positive results when they went to see Rossi’s device.

On Sept. 29, Rossi responded on his blog:

WARNING: THE SNAKE HAS WRITTEN IN HIS BLOG THAT NASA MADE A NOT POSITIVE TEST WITH US. THIS IS TOTALLY FALSE. I AM BOUND FROM A CONFIDENTIALITY AGREEMENT AND I CANNOT GIVE DETAILED INFORMATION, BUT I CAN SAY THAT:
1- WE ARE IN CONTACT WITH NASA, WHO WANTS TO TEST OUR ECATS TO TEST THE POSSIBILITY TO MAKE THEM USEFUL FOR THEIR PURPOSES
2- NASA’S DENNIS.M.BUSHNELL HAS SAID PUBILCLY THAT NASA WILL BUY AN E-CAT AS SOON AS IT WILL BE POSSIBLE TO TEST IT
3- OUR RELATIONSHIP WITH NASA IS TOTALLY POSITIVE

On Sept. 29, New Energy Times sent a query to Robert Jacobs, NASA deputy associate administrator for communication.

We showed him Rossi’s comments and asked him these questions:

1. Did NASA personnel observe any positive results in September?
2. Do any NASA personnel have, at this time, any interest to participate in or observe additional tests of Andrea Rossi’s “Energy Catalyzer” device?
3. Does any NASA employee have any intention to buy one of Rossi’s devices under any circumstances at this time?

Jacobs replied on Sept. 29.

“I’m not personally aware of such activity, but I will check with Langley, which is where Dennis Bushnell is located, and I will have someone there contact you,” Jacobs wrote.

New Energy Times then sent the questions to Robert D. Wyman, NASA Langley news chief, on Sept. 29.

New Energy Times spoke with Wyman on Oct 4.

“Dennis Bushnell is out of the office this week, and I don’t have any further information,” Wyman said.

In other related news, Rossi is going to attempt today, for the 11th time, evidence for his claim.

This is not, however, Rossi’s promised and long-anticipated October public demonstration and delivery of a 1 megawatt power plant. The test today will be performed only on one of 52 units composing the promised 1 megawatt power plant.

On Sept. 14, Lewan published photos and video of an impressive-looking shipping container that housed 51 individual boxes, each containing a 30-litre tank, with interconnected plumbing and electrical parts sticking out of each one. The 52nd unit was on the bench for testing.

Rossi has failed to demonstrate excess heat in a single device 10 times in a row.

A recognized technology expert who saw the 1 megawatt shipping container in September told New Energy Times that he wasn’t able to overlook the obvious.

“You can’t deliver one megawatt of steam through a 2½-inch pipe unless you go hypersonic,” the expert said.

So observers of the big 1 megawatt demonstration that Rossi promised for October should look for steam exiting the shipping container in excess of 768 mph.

Internet rumors that the Rossi test would be performed using University of Bologna facilities are incorrect, according to an e-mail New Energy Times received yesterday from Paolo Capiluppi, the head of the Physics Department, in response to our questions.

“The contract is not yet active,” Capiluppi wrote. “The university is not involved with the demo by Rossi tomorrow and is not providing any university facility or laboratory.”

Other Internet rumors suggested that Rossi had granted Lewan an exclusive on the story. But Lewan told New Energy Times that is also incorrect.

“I haven’t been offered any exclusive,” he said.

As of 11 p.m. Stockholm time on Wednesday, Lewan would not say whether he would attend.

The E-Cat story has 26 days left to play out.

The discovery of fire a million years ago must have been terrifying to cave men and women. Since that time, many people have died and much damage to the earth has occurred as a result of chemical energy released through fire. Nevertheless, that chemical energy found its place in the world, providing great benefits, and most people take it for granted.

In stark contrast, humankind began to develop and use nuclear energy less than a hundred years ago. In 2010, nuclear energy provided 13.5 percent of worldwide electricity.
