Don't feed the seagulls................
—The electric power was then cut off and the E-cat continued to operate for 35 minutes without external energy input.—
Although I’m actually very interested and cautiously excited about the e-Cat stuff, if I may play devil’s advocate for a sec - A Leaf will do that.
To get the output up to 20KW per unit (1MW/52).
Having 20KW individual units makes the individual E-Cats "much" more interesting, as that's about the size needed to drive a home power system.
There is a PDF at the NYTeknik site (link in story) that gives more details. Remember....this is a NEWS STORY, and even someone as technically astute as Mats Lewan has to leave some details out.
They even state that in their results:
The energy calculation of this test has proven to be difficult. We had limited time to plan and perform the test, and analyzing the data we realize that we would have needed more data for a fair calculation.
I did a better job of system measurements for my high school science fair project (Ocean Thermal Energy Conversion)
They measure the output water temperature, note it is a lesser volume than input but don't measure that flow rate, volume or the steam generated?
Look a wee bit closer. They DID measure the output liquid water flow. And they know the total amount of water through the system from the initial weight of water, weight of water added, and water left in E-Cat at end of run.
I haven't run through any calcs yet (no time), but I'm sure someone on Vortex-L (probably Alan Fletcher) will do so.
I think the key point here is the steam temp (130C), which is well above the saturated steam point.
They stated themselves the data measurement was insufficient. In their results they have to use qualifying phrases like “power developed after boiling should have been approximately 3.8 kW”
They raised the temperature inside the device with a power input to the system prior to turning it off. At that point, they have stored energy.
They may really have something. It is so darn frustrating to see them leave out obvious stuff that wouldn't cost but a couple hundred dollars to monitor and record.
True. I also realized after I posted that the additional size would not include equipment to convert heat to electricity, since (if I understand it right) it is only heat, not electricity, that needs to be maintained to keep the reaction going in self-sustaining mode.
I don’t understand why he would need to keep adding heat to a nuclear heat machine.
In an unrelated note, Eestor is now two years late in releasing their prototype unit, about 5 years late from their initial promises. Europositron is about a decade late and being prosecuted for fraud.
Jed Rothwell was stating that there were working LENR water heaters back in the mid 90’s and that they would be available for retail soon.
This demonstration is not reassuring.
"Ass-ume". Remember that?? I'm not a "fan" of Rossi or "fringe science". My position throughout has been look at the data, not speculation, not innuendo, and not knee-jerk its a scam responses. I have always maintained that it was POSSIBLE that it could be a scam, but based on the available data, it appears to be real.
The attendees at the demonstrations were neither partial nor incompetent. And I have the professional qualifications to judge the methods, the data, and the people.
Has it been validated to the point of scientific certainty...no. I await further developments on that. There is one datum that will convince me in Rossi's favor, and that is verification of the delivery of E-cats to the University of Upsala and the University of Bologna. If that happens, it cannot be a scam.
If it is a scam, it will turn out the be the Michaelanglos David of scams, and will probably go down in history as precisely that.
"Can we talk about this? What's your exit plan? I see three obvious options for you when this doesn't materialize:
"1. That you were just arguing on Rossi's behalf for fun, and since you never said the words "Rossi's machine will work" you weren't actually wrong about anything."
At no time have I "argued on Rossi's behalf". If I've argued for anything, it is the data.
"2. That Rossi is being suppressed by a conspiracy, and therefore you aren't wrong despite the fact that his machine appears not to work."
Whether Rossi has been "suppressed by a conspiracy", I neither know nor care. But "cold fusion" as a subject for research certainly HAS been "suppressed by a conspiracy" using the exact same tactics that the AGW promoters have used to suppress opposition. This is widely documented.
"3. That you were wrong about Rossi, but a real cold fusion breakthrough is right around the corner so next time will be different."
Wrong yet again. Do I believe the overall "cold fusion" phenomenon is real?? "You betcha". But not having a good crystal ball, I have no more way than you of knowing what will happen or be forthcoming from other CF/LENR/LANR researchers.
Now. Let me ask YOU. What will YOU and the rest of the seagulls do if Rossi's tech turns out to be real?? I expect "crickets".
“- The temperature inside the E-cat, which we assume is the steam temperature, reached over 130 degrees, while the pressure was probably about one atmosphere.
- The steam was invisible at the outlet indicating high steam quality.”
These two things mean nothing. Steam can be invisible without being high quality. You measure steam quality by the amount of water that has yet to be put into a gaseous form at “about one atmosphere”.
assuming the stated 135*C (=275*F) and 1 atmosphere = 14.696 lb/in^2 absolute, then steam tables indicate about 29.5 degrees of superheat at 275*F. Constant superheated steam at one atmosphere isn’t reached until around 320*F. that’s what is needed for steam turbines in order to limit long term damage to the blades/fins.
It’s been so long since I’ve used my tables, I’m having trouble calculating the vapor content at those numbers...the tools are there why don’t people use them...
if I may play devils advocate for a sec - A Leaf will do that.
***You mean an electric car, right?
That’s a classic apples & oranges comparison. When the Wright brothers were flying around in circles at Huffman Prairie, the press refused to publicize it because, after all, dirigibles had been doing that for years. The issue is the underlying technology and what its impact will mean. You don’t see a lot of dirigibles these days.
chirp chirp cricket
or is it “SQUAWK” for a seagull.
I like what Jed Rothwell said on Vortex, that he gets irritated by all these sideliners who are simply betting on failure. Failure is always a possibility, but these vulture-seagulls seem to get a perverse pleasure from it.
Rossi did a test a while back where there was no phase change, so the calculations were far simpler. I don’t know why he even bothers to generate steam. Just keep the water liquid, measure the temperature. This flamboyant side that Rossi exhibits is his biggest character defect and could cost him dearly.
I think mostly because one of the markets he is targeting first is building heating. As I understand it from comments on another thread here, saturated steam (rather than superheated) is the best agent for that purpose. Superheated is desirable is you're planning to generate electricity.
I’m interested in how you and some other fans of Rossi and fringe science are going to respond when he doesn’t revolutionize energy production in October, or even produce a single watt more economically than current methods. Can we talk about this? What’s your exit plan?
***My plan all along has been to find a place to put my money where my mouth is, again. I’d love to have seagulls put their money where their mouth is. I have money in my pocket as a result of this approach. And all of this was before Rossi came on the scene.

At this point, the available data "does" validate Rossi. What am I "supposed" to say...that it doesn't??? As an ethical scientist, I can't say anything else. Pointing this out is hardly "arguing on Rossi's behalf".
By the same token, and by that same ethical requirement, I also point out the shortcomings of the inaccurate critiques of his data, as well as the shortcomings of Rossi's data (lack of independent review). As Martin Luther said "Ich kann nichts anders".
If the data changes, my position will change with it.
