  • Arcturius

    Thank You.

    Which frequency does that light have ?

  • Andrea Rossi

    Arcturius:
    I have already answered this question many times: the wavelengths spectrum of the Ecat SKLed light does not match with the solar panels, that are designed for the spectrum of the sun light.
    Warm Regards,
    A.R.

  • Arcturius

    Dr. Rossi,
    If Your device produces 2500 lumen per watt, why not cover it with solar cells to gain even more energy out of it ?

    Nice regards, Arcturius.

  • Dear Andrea,

    On the 18th of March you answered to Stephen that you would publish a picture of the SKLed and a data sheet within 10 days.
    I assume something is causing a delay, but it would be great to publish them even if the final data and product might be slightly different.
    What do you say?

    Dear Andrea,

    There’s a lot of discussion about how the SKLed could last 100,000 hours.

    I think the answer can be found in your answer to Albert, 2021-03-27

    “No, we turn almost all the energy into photons, reducing the phonons to a minimal part.”

    This would also exclude the possibility of using a TEG to generate enough energy to power the SKLed.

    Regards,
    Dan C.

    PlasmaFan:
    1- no
    2- the data-sheet will be made public at the presentation
    3- before the presentation we will not distribute the Ecat SKLed, while the certification of the independent third party is on course
    4- see 3; by the way, after the presentation everybody will be able to buy the Ecat SKLed and make all the tests he wants.
    Warm Regards,

    It means that the distance between charges that are in the same cone in Minkowski space-time must be a light-like (nilpotent) vector.

    Dear Andrea,

    1) Will the E-Cat SKLed be configured to be powered by both a wall connection and a battery? For example, if someone wanted an SKLed for emergency lighting during a natural disaster could they power it with a battery? If so, what battery would be needed?

    2) What is the total output in Lumens of the SKLed?

    3) Will you consider providing Frank Acland of E-Cat World with a unit before the demonstration so he can use it, run tests, and provide a report of his own? It would be impressive if he announced that he had ran your product and a competitors product of the same output in lumens side by side with power meters and your product used far less power.

    4) Would you consider providing Mats Lewan with a unit for the same purpose?

  • Patrick

    Dear Andrea,
    You discovered that the quality of the electricity coming out of your SKL works really well with LEDs.
    Was it serendipity or something else that *led* to the marriage?

    Dr. Rossi:

    Far UV-C light at 222nm has been shown to eradicate bacterial and viral pathogens including Covid-19 without damage to human skin or eyes. See the website: https://www.nature.com/articles/s41598-018-21058-w. Optical sources at 222 nm can therefore be used in habitable spaces such as hospitals, schools, stores, homes and mass transportation to eradicate viruses and bacteria. Excimer lamps are available that emit at 222 nm wavelength but are currently too expensive to permit widespread utilization ($1K-$3K). In principle, there is no reason why LEDs cannot be manufactured to emit at almost any wavelength,by adjusting the alloys of the semiconductors used. Far-UVC LEDs based on such alloys have already been demonstrated in the lab with limited commercialization using Al-GaN with emission wavelengths at 222 nm. Unfortunately, these devices have an efficiency of barely a few percent – well below the 20–40% needed to eradicate pathogens in habitable spaces. No solid-state lasers at 222 nm which might provide higher output have been demonstrated to date. Low cost, high efficiency LEDs with the required optical output power could provide a revolutionary solution for pathogenic disease elimination for all of mankind. It appears that your technology that is now used in the SQLed when applied at the 222 nm wavelength would minimize the future need for vaccines and therapeutics to keep the world healthy.

  • Robert Dorr

    Dear DR. Rossi,

    You are, happily for everyone paying attention to your continuing progress, letting us know more and more information regarding your hard work. You have stated that the light has the efficiency of approximately 2500 lumens per watt. Can you tell us the total lumen output of your device or am I to assume that the output of your device is 2500 lumens.

    AS always, I wish you continued success.

    Sincerely,

    Robert Dorr

    eernie1:
    We are making a certification that will exclude any ionizing radiation and UV radiation.

  • Andrea Rossi

    Brokeeper:
    Thank you for the suggestion.

  • Brokeeper

    Dear Andrea,

    Have you thought of making a version of the ECat-SKLed that emits only UV for the purposes of disinfecting air ducks (home or commercial) and hospital rooms from viruses and microbes for health reasons? (A follow-up comment I made two years ago)
    Brokeeper

  • I think that your main concern should be showing that no harmful nuclear energy output is present in your device. Some UV output is generally accepted from light sources and the illumination devices certified for general use, as long as it remains below acceptable levels.
    Keep emphasizing that your device does not use harmful nuclear reactions.
    Warning regards.

  • Andrea Rossi

    Frank Acland:
    It is not mandatory, but it is a big asset not to emit UV: most lamps emit UV, which are dangerous for health; I want the absence of UV to be certified, because the SKLed must be the most efficient lamp of the world and the safest of the world too.
    Warm Regards,
    A.R.

  • Iggy Dalrymple

    To All Readers of JoNP,
    My humble suggestion is for all followers of Dr Andrea Rossi is to purchase one extra SKLed (streetlamp version) and donate it to your local municipality. This action could greatly accelerate the distribution of E-Cat technology.
    Best Regards,
    Iggy

  • Frank Acland

    Dear Andrea,

    Do I understand correctly that producing no UV light is a requirement for the SKLed safety certification?

    Kind regards,

    Frank Acland

    “We expect 100000 hours of operative lifespan”!!!
    This means more than 20 years !!!
    WOW … inbelievable.
    This is a real revolution.

  • Svein H. Vormedal

    Dear Andrea.
    My question was meant to distinguish between the ECAT SK part and the Led part in relation to the total improvement that emerges in relation to the Philips led. (I doubt that the Led solution you use, in itself, is more energy-efficient than the new one from Philips.)
    Regards,
    Svein H. Vormedal

    Dear Andrea.

    If you need to handle UV you could consider Quartz or LiFl optics. These are transparent to UV.

    Then choose a Semiconductor optimized for that such as GaN PV either in itself or as part of a multi junction chip.

    Just some crazy thoughts.

    Best Regards

    Stephen

  • Stephen

    Dear Andrea

    Regarding PV what you say about UV is very true and important in space.

    Inside the atmosphere and under glass much of the UV in the solar spectrum is removed.

    IR on the other hand is about 55% of the solar spectrum.

    So Solar PV tend to try to capture much of the NIR too.

    Silicon based PV has a band gap that corresponds to 1.12 eV which corresponds to a wavelength 1107 nm in the NIR.

    At shorter wavelengths higher energy than the band gap the SA is increasingly inefficient due to the spectral response which decrease linearly at higher energies this makes is very in efficient at blue frequencies.

    https://www.pveducation.org/pvcdrom/solar-cell-operation/spectral-response

    In the case of LED’s there is almost no IR. So it is more useful to choose a band gap corresponding to 700 nm such as CdSe that would then be more efficient at shorter wavelengths including the blue and increase the open circuit voltage. There are likely other options.

    https://en.m.wikipedia.org/wiki/List_of_semiconductor_materials

    There are also options to use multijunction band gap PV to improve efficiency.

    If white light is not needed then the optimum is to match the LED output and the PV band gap.

    It’s been discussed a bit here:

    https://e-catworld.com/2021/03/20/e-cat-presentation-announced-for-november-30th-2021-in-sweden/#comment-5314616409

    But I admit it’s a bit speculative and may have some errors in it and even idle possible is likely to have marginal overall effect. Obviously it’s all made obsolete by the Ecat SKL when it is released apart from entraining curious minds.

    I mention it just in case it can help in someway.

    I do wonder if viable if it could all be miniaturized in to your device or even reactor in some way. Probably it’s too crazy and complicated idea though.

    Thanks

    Stephen

  • Stephen

    Just a note I did it again CaSe should be CdSe (useful for the current LED) CdTe would also be good. There are other LED spectrum PV semiconductor band gap optimizations possible.

    Stephen:
    If you keep out the UV the efficiency will be very low, whatever you match.
    Warm Regards,
    A.R.

  • Andrea Rossi

    Stephen:
    Understood,
    Warm regards,
    A.R.

  • Stephen

    Sorry the last sentence was a bit garbled. It should be An Optimized LED with an output perfectly matched to a PV with a perfectly matched band gap. CaSe comes to mind.
