    Dear Andrea,

    the E-Cat SK has been running commercially for about 2 years in the industrial sector.
    What is the reason why this is still happening in secret and why there has not yet been a scaling of media interest?
    1) State political reasons
    2) Corporate policy reasons
    3) Technical reasons
    4) Something else

    Warm greetings

    Dear Andrea,

    Would the AI improvements that you are using in the SKL and SKLed Ecats also improve the SK heater technology?

    Many thanks,

    Dear Andrea,

    As an alternative to a small E-Cat SK for heating rooms, a small E-Cat SKL is also suitable for powering infrared heaters.

    Infrared heating has many advantages over heating by convection:

    1. With infrared heating, the air is not primarily heated, but all objects, items and structural components in the room (e.g. furniture, floor, ceiling, walls). These absorb the infrared radiation (long-wave heat radiation) and emit it evenly to the entire room. This creates a pleasant warmth that is reminiscent of the natural rays of the sun.
    2. As soon as the infrared heating is switched on, it does not take long before a pleasant warmth is noticeable. Since the rays have a direct heating effect, the entire room air does not have to be heated first over a certain period of time.
    3. The time to heat up is only about 5 minutes
    4. Like any other heater, the infrared heater can be controlled with a thermostat
    5. Infrared heaters can be installed as underfloor heating and on all walls and ceilings.
    6. They are available as mats, panels or wallpapers in various watts / sqm
    7. Infrared heaters are suitable for new construction or renovation of buildings regardless of their size
    8. A small E-Cat SKL can be installed per room, alternatively a larger E-Cat can supply several rooms with electricity for infrared heating.
    9. The costs for infrared heating are around € 60 per square meter including installation.

    The heating output for infrared heating depends on the insulation of the house, the external walls in each room and the desired temperature.

    An infrared heater that is powered by the E-Cat SKL is the ideal heater in my opinion.

    Many greetings
    Ulrich

    Dear Andrea.
    In any home, relatively large amounts of hot water are needed. Both for personal, dishes and room cleaning.
    Hot water / hot oil is also used extensively for space heating through heated floors, radiators and fan coils.
    This may also include the thawing of ice and snow by outdoor use areas and swimmig pools.
    Using Ecat SK to heat water / liquid with a COP of close to 60 will be a dream scenario for anyone who has a significant energy consumption in such areas.
    If an Ecat SK can be produced with a simpler and more stable operation and with a significantly higher efficiency than the SKL variant, I have no doubt where I would start a production.
    Sincerely, Svein H. Vormedal.

    Dear Mr. Rossi,
    regarding the conversation with you and Mr. Acland:
    You have already invented a little ecatSK in the form of the ecatSKLed which is able to heat with 32 Watt and an electric consumption of 4 Watt. So make it just about 60 times bigger (and without light), 1920 Watt output with a wattage/input of 240 Watt.
    It would be better to produce single heaters for rooms instead of a central heating system with 10-50 KW which needs specialists and masonry openings for pipe laying. Convection- and oil based electric radiators would fit the best, like: https://www.inhabitblog.com/appliances/electric-radiators/electric-radiators-best-heating-option.html
    Also an electric water heater/boiler with the same wattage in different sizes of 30 to 100 liters should be in the product line.
    Best regards
    Michael

    Dear Dr. Rossi,

    I think it is very easy to make a heater based on SKLeds when you let them burn in a black box, which is a good black radiator. But even burning SKLeds directly in a room will also efficiently convert all light into heat when the photons will be absorbed by the surrounding… (100% in the end). Can you agree with my simple calculation?

    Total consumption of 1 SKLed = 4W (2W heat dissipation + 2W light).
    Total heat output of 1 SKLed = 2W heat + 16W light (2W @ COP 8 = 16W) = 18W (finally heat).

    So in my reasoning when I would buy 100 SKLeds I could make a simple heater of 1800W, consuming 400W at a purchase cost of $2,500 (100 x $25). The power consumption could be about half when one electronic driver could drive all 100 SKLeds at once.

    Does this makes sense?

    With kind regards,

    Brice

    Cheryl McEwen, the wife of Rob McEwen, McEwen Mining, is a very interesting woman
    ( https://en.wikipedia.org/wiki/Cheryl_McEwen ) She is also the founder of Make My Day Foods Inc, Toronto. Which
    brings us to the ECatSKL. MMDF makes and sells a product called the veggie puck
    https://www.foodbevg.com/CA/Toronto/745027592231241/The-Veggie-Puck which presumably uses lots of greenhouse space and Energy in Canada growing all those cool vegetables.

    Please update us on how your ECatSKLed green house tests are going, taking note that vegetable availability is considered a major health crisis in Canada. Vertical SKLed-illuminated walls of vegetables in Greenhouses heated by ECatSKLs should help. Note vegetable prices in Canada are skyrocketing.

    I think that a small Ecat space heater would satisfy all of my heating requirements!

  • Iggy Dalrymple

    Dear Dr Rossi,
    Frank Acland asked, “Would it be possible with E-Cat technology, to make a device of SIMILAR SIZE that puts out a lot of heat, and maybe not so much light, with minimal power input, so it a very efficient heater?” You replied, “Yes.”
    Weren’t you referring to the E-Cat SK, which is much larger? Would be feasible and economical to produce a small room-sized E-Cat SK?
    Best Regards,
    Iggy

  • Dan Galburt

    Dear Dr Rossi,

    I suggest that the E-Cat SKLed lamp can be used to illuminate a room by mounting it on the top of a support stand with the lamp pointed upward at the ceiling. If the ceiling is coated with flat white paint then the E-Cat SKLed should provide ample indirect lighting for the room and can be dimmed to the desired brightness. Alternately, the E-Cat SKLed can be placed at the center of a dining table pointing directly upward providing lighting for the dining area. Color filters can be used to provide a party atmosphere. Obviously power usage would not be a concern.

    Best Regards,
    Dan Galburt

  • Frank Acland

    Dear Andrea,

    Thank you for your response to my questions. I was under the understanding that the E-Cat SK is only an industrial product. Maybe I am wrong.

    Will you be releasing a home heating product that could be ordered by anyone?

    Kind regards,

  • Svein H. Vormedal

    Dear Andrea.
    I agree with Calle H. In indoor lighting, there are today, probably 1000 different designs of lamps.
    Even light bulbs, seem to be available in nearly 100 different editions.
    In my living room I now have 14 ceiling mounted spotlights.
    I depend on being able to regulate the amount of light from these in two central points.
    Since SKLed most closely resembles spotlights, can they be regulated centrally?
    Sincerely, Svein H. Vormedal.

  • Frank Acland

    Dear Andrea,

    You have said that the SKLed puts out a lot of light, and very little heat, with minimal power input, so it’s a very efficient light.

    1. Would it be possible with E-Cat technology, to make a device of similar size that puts out a lot of heat, and maybe not so much light, with minimal power input, so it a very efficient heater?

    2. If it is possible, do you think it would make business sense to make such a product (In colder weather, lots of people need space heating for their homes and businesses)?

    Many thanks,

    Frank Acland

  • Andrea Rossi

    Calle H:
    During the presentation tthis issue too will be explained.
    Anyway the Ecat SKLed is fit for any fixed positioning.
    Warm Regards,
    A.R.

  • Calle H

    Dear Dr. Rossi,
    With the current design of the SKLed it is not clear what the typical application of the lamp will be. There must be some other use than just a desk top artefact. I would guess without practical applications it may be difficult to reach a million orders. I would think that large volume users could be grow lamps and street lamps. Both are in the same light power range as the SKLed but may have different beam patterns, colour temperature, mechanical fittings and IP class. Will you at the Stockholm presentation show different variants and applications of the SKLed lamp?
    Kind regards,
    Calle H

    Dear Andrea,

    A. You have previously mentioned that the E-Cat SKLed takes several seconds to start-up, does the time period from switching on to reaching maximum light level vary with ambient temperature?

    B. When varying lamp light level from minimum to maximum is change immediately visible or is there a noticeable time lag?

    C. When the lamp is switched off, does the light terminate immediately or does it fade out?

    Regards,

    Keith Thomson.

    Dear Andrea Rossi,

    You politely answered my suggestion. My question is whether the conceptual suggestion of an eCat electrical generating unit (call it whatever name or symbol you want) can accept grid power, generate much more electrical energy, and can it power resistive loads using a transfer switch.

    In my mind, the approach seems elegant. You avoid capacitive loads such as central air conditioner or some types of furnaces. You avoid endangering lineman working on grid power lines. The generator replacement methodology is a proven and an accepted approach.

    Under this approach, the eCat unit becomes very similar to a generator back-up system, although it is used when grid power is available. Rewiring an existing house is avoided. All required changes can be made at the home’s electrical box by a qualified electrician.

    1. Will the eCat unit be capable of self-regulating so when the load changes, the power generation changes?

    2. Can the eCat produce AC power in phase with the incoming grid power?

    3. Can the neutral of the eCat output power be tied to the home’s neutral line without adversely affecting the eCat output power?

    4. Can the eCat electrical generator handle capacitive loads such as found on central air conditioning units and furnaces?

    5. Can the eCat electrical generator produce acceptable 2-phase 240VAC, 60 Hz (or 50 Hz) power as found in the residential home?

    Dr. Rossi,
    In relation to electric aircraft, they appear to be getting more attention:

    Link: https://www.geekwire.com/2021/magnix-wins-74-3-million-nasa-demonstrate-electric-aviation-technologies/

    A couple excerpts:

    “Everett, Wash.-based MagniX will be getting $74.3 million from NASA over the next five years to demonstrate electric propulsion technologies for aircraft.”

    “The fixed-price / cost-share award is being made through NASA’s Electric Powertrain Flight Demonstration program, or EPFD, which aims to introduce electric powertrain technologies to U.S. aviation fleets no later than 2035.”

    “Another company, Cincinnati-based GE Aviation, is being awarded $179 million through the same program.”

    —-
    Hypothetically, which seems more realistic– battery-only air travel or battery-plus-Ecat-SKL air travel?

    Doesn’t 2035 seem like a possible timeframe for an airborne SKL?

    WaltC

  • Gerard McEk

    Dear Andrea,
    To Ruby you said that you are very close to receiving certifications.
    Just one question: Are those certifications for the SKLed or the Ecat SKL or both?
    Thanks if you can answer.
    Kind regards, Gerard

    @Jitse and Chuck
    It depends on the country and the insulation of the accommodation. In France, for 120m2 at 1000m altitude, my supply contract is based on 9kva, with insulation to the latest standards (rt2012). for an annual cost of 1200 €. (In sharp increase to come with the abandonment of nuclear – it’s not done! -) the standards are for 19 ° inside and -10 outside … the current supply is 230v

  • Ruby

    Dr Rossi,
    How is going on the certification issue ?

  • Jitse

    hello Chuck,
    This type of inverter (50 KWh ) seems to me to be right for industrial, my target is the individual users such as my neighbors and relations (1 to 10 KWh 8760 to 87600 kWh per year and of-grid users fully CO2 free).

    Is it confirmed that on December 9 the Ecat SKLed and SKL will be presented, respectively the SKLed as a product for sale and the SKL as a prototype ?
    Best wishes,
