Mathfan,

When you roll a six-sided die from a pair of dice, the probability of getting a ‘3’ (or a 5 etc.) is 1/6 (0.1666). If you roll the same die 5 times, the probability of getting the same number is (1/6)^5 = .0001286 . That is about 128 times out of 1 million. When 1 million e-cats have been delivered, no one would want 128 problems.

The Sigma 5 test must be more stringent than 128 examples out of a million.

Statistical regards,

Joseph Fine

@/P
The concept of Sigma 5 is this: assume you throw a dice: if one of the 6 numbers, for example 3, wins one time, it is normal = Sigma 1 probability, if exits 2 times, it is almost normal = Sigma 2, 3 times rare = Sigma 3, 4 times very rare = Sigma 4, 5 times impossible = Sigma 5: it means all the faces are equal = 3. In the case of the Ecat tests, means that successful operation is always possible after enough number of tests to exhaust any possibility of unsuccessful event.

Sorry, it regards series of factors that are confidential, although this allows to imagine the series of difficulties we had to overcome.

Dear Mr Rossi,
I have a question regarding your sigma 5 tests. What kind of event/phenomenon are you measuring that should result in 99.9999% probability?

Dear Dr. Rossi,
assumed you reach the goal of one million ecat in 1.November 2024:
When you are able to to deliver the first ecat to the customers, how long would it take?
Warm regards,

Dear Andrea,
As an audio and computers guy, I’m really looking froward to having less cables when dealing with speakers and various hardware. On a larger scale, do you see the introduction and/or future integration of the E-Cat with technology as the end of power cables for many everyday electronic devices? Or are there limitations that prevent such a dream from happening?

All the best,
Brian

Hello DR Rossi

Are you more confident with
Upcoming October Demo than

Are you working with a major electric
vehicle manufacturer, and a representative
of this partner will be on site to help with the demo?

Dear Andrea Rossi,

Please clarify what you mean by
“our Team didn’ live through such time wetting the water”

Is this to say that your team didn’t waste there time on an inferior approach, or some other meaning?

• Andrea Rossi

Anonymous:
Right, but that was 4 years ago; our Team didn’ live through such time wetting the water,

Years ago Rossi made a presentation of the Ecat in Miami with the plasma reactor in view, with the plasma that danced, Rossi said, like a ballerina: but in that case the energy density was qite minor: why ?

• Andrea Rossi

Ronaldo Fuentes:
Actually, that’s 3.3 MW/cubic meter, but that’s just the volume of the vacuum containing the plasma, which is the heart of the Ecat…but the heart is not the body !
The volume of the body is obviously bigger and its dimensions depend on the specific situations and applications.
Warm Regards,
A.R.

• Ronaldo,
I think that you mean 3.3MW per cubic meter (multiply both parts by 1000)

• Ronaldo Fuentes

Dr Rossi,
3.3 W per cubic cm is interesting: that means 3,3 cubic meters per MW: is this valid for a massive production too, or it is just valid for special prototypes ?

• Andrea Rossi

Steven Nicholes Karels:
It is proportional: yes, moreless 3.3 W/cm^3
Warm Regards,

• Steven Nicholes Karels

Dear Andrea Rossi,

So, the power output linear proportional to the reactor volume? Or approximately 3.3W per CC?

• Andrea Rossi

Steven Nicholes Karels:
Forgot to say in my answer to your comment: the volumes indicated are of the sole plasma reactor, not counting all the remaining items.
Warm Regards,
A.R.

• Andrea Rossi

Steven Nicholes Karels:
Sorry , I involuntary missed this comment of you.
Here are the answers related our prototypes:
1- 10 W
2- 3 kW, 0.9 L ( 900 cc )

Dear Andrea Rossi,

1. On the smallest reactor (3cc), how much average power was generated?
2. What is the largest reactor, its dimensions and its average power?

• Steven Nicholes Karels

G. Kaiser,

You posted “Is there a way of generating electricity without stopping the ecat in the event of an overload?”

One could place a current limiting circuit between to NGU and the load. Such a circuit would decrease the voltage going to the load so that the maximum current was not exceeded. The NGU would “see” a load that is its maximum current. The load would “see” a decreased voltage at its input.

• Andrea Rossi

Sergio:
1- yes
2- yes
Warm Regards,
A.R.

• Andrea Rossi

G.Kaiser:
No, it is not possible, so far.
Warm Regards,
A.R.

• G.Kaiser

Dear Dr. Rossi,
Is there a way of generating electricity without stopping the ecat in the event of an overload? For example, if I connect a kettle with 2KW to an ecat with 1KW, so that the kettle is then only operated with 1KW? As a result, the kettle with 1KW then only needs twice as long, but it still works. The same with a resistance heater etc.
Wouldn’t it be possible to do this somehow with ohmic load in these examples?
Best regards
G.Kaiser

• Sergio

Dr Rossi,
Will he streaming of the EV demo cover all the duration of the test ?
Will it possible to watch both the competitor EVs without interruptions for the whole duration of the race, without “black angles” along the track for either EV ?
Thank you if you can answer,
Saergio

If Dr Rossi had Nikola Tesla
on his team we would be on
Mars by now.

@Sam
Kudos for your links to the work of Tesla; actually, his modality of work, his lab, his dramatic life have analogies with A.R.
Don’t you think so ? Maybe A.R. has adopted his model ?

Dear Andrea,

ABT already has charging electronics for the ID BUZZ, which also feeds solar power into the battery while driving.

I hope my dream of an ID BUZZ GTX long version with 9 KW E-Cat will be fulfilled in 2025.

Dear Andrea

are our pre-orders from 2022 still valid ?

Or will there be new Ecat models and we have to restart from
the beginning ?

Best regards
As well Andrea 😉
