  • Koen Vandewalle

    What I meant: can it be mounted on a plunger that is operated by a camshaft ?

  • Koen Vandewalle

    Dear Dr. Andrea Rossi,

    Could it be possible to install the E-Cat QX on a moving plunger subjected to accelerations of 1000G to 10000G and 2cm displacements?

    In any case, on a fast moving part in a machine.

    Kind Regards,
    Koen

    Dear Andrea
    I agree in your answer to K. Wandewalle. October 28.
    I also believe a free piston Stirling engine may be the best solution for electricity production.
    It contains only one moveable part. It is hermetically sealed, as a refrigeration compressor.
    This may grant a sigma 5 solution for the total unit, and minimal need for maintenance.
    I suppose the most efficient, cheapest and most secure heat exchanger may be constructed as a bloc of metal with the necessary micro tubes for the gas and cylinders that matches the QX. The less material in the bloc, the better performance. There may be more than 20 separate ways to shape such a heat exchanger and to customize it to the QX and an efficient fabrication. These will function without need for steam or hot liquid for transition of the heat from the QX to the gas in the engine.

    Mankind’s need for electricity varies a lot. A Stirling engine may cover the need from less than 1 kW to the largest plants for aluminum production. The best price for electricity may be in the smaller part of the marked and for use in areas without a grid. Here is it probably vise to start the marketing.
    Vehicles are also a high price part of the marked. As pointed earlier, the average need of energy for driving a car is low.
    Fitted with a Stirling generator at 20 kW, and a battery of 10% of today’s size, will give a Tesla infinity mileage and heat or AC to the cabin. If the cars low point of gravity may be kept it may function equivalent to today’s models. Cars are not the most important marked, but probably the part that will give you most attention in a brief time.
    A question at the end: When will we be informed of the date of the presentation?
    Best regards Svein Henrik.

    Perhaps a small SCO2 (Super-critical Carbon Dioxide) engine may be a candidate. See “The Mighty Mite” article, below.

    http://www.supercritical.tech/wp-content/uploads/2015/11/Mechanial-Engineering-SuperCritical-CO2-Overview-by-Steven-Wright.pdf

    Note: The typo “Mechanial” instead of Mechanical is actually the correct link address.

    On a larger scale, hundreds of Megawatts of electricity can and will be produced.

    But at a smaller scale, about 40-80 kW mechanical and/or electrical power could be produced.

    Miniaturizing a SCO2 engine to approx. 40+ kW should be possible. As usual, the Design Size, Weight and Power (SWAP) details

    have to be worked out. (” It’s only an Engineering problem. ” 😀 )

    Dear Andrea and blog readers,
    Steam engines are not relevant as E-cat engines for the present, but maybe in the future.
    In 1974 SAAB in Sweden made a 250 HP 9 cylinder steam engine prototype that could be fit in a car. http://www.saabhistory.com/2008/04/04/the-nine-cylinder-saab-steam-engine/
    If Leonardocorp just puts together an E-CatQX driven Stirling engine with a generator as a prototype, maybe the development of steam engines will start again in the future.

    Best Regards,
    Karl-Henrik

    Koen Vandewalle,
    It works the other way: once we have an engine, we adapt our assembly to it.

    Dear Andrea,
    Speaking of Jay Leno’s cars, he has a nice video of his 1925 Doble Series E Steam Car– Lots of good high-pressure-steam discussion in the video: 850 degree (Fahrenheit, I assume) 1000 PSI steam, closed system, 3000 degree firebox, steam whistle (it has to have one of those!). Link:
    https://www.youtube.com/watch?v=ACO-HXvrRz8

    Also, on the subject of steam cars, ExtremeTech has an article: “Are steam cars poised for an epic comeback?”:
    https://www.extremetech.com/extreme/148416-are-steam-cars-poised-for-an-epic-comeback

    Which also mentions current steam engine work being done by Cyclone Power Technologies in Pampano Beach, Florida.

    Florida seems to have all the fun these days!

    Household E-CAT ? I think never ….

  • Koen Vandewalle

    Dear Dr. Andrea Rossi,
    Can you provide us with the precise dimensions, optimal surface temperature and heat conductivity, radiant power, and electrical connections of the E-Cat QX?
    Then we can search for realistic engines with more people.

    Kind Regards,
    Koen

    Dott. Rossi, il problema delle automobili elettriche è che per ogni auto prodotta 6.000 dollari vanno in Cina per le batterie. Dato che non riusciamo ad avere costi concorrenziali per la produzione di batterie il tuo e-cat sarebbe la soluzione a tutto.

  • Marco

    Dear Andrea,

    the considerations of Karl-Henrik Malmqvist are very important and interesting.
    With standard heat sources, by combustion, you must necessarily put in fresh and cold air and put out warm exaust gases. THis is a waste, because this waste head does not flow through the stirling engine. ECat QX does not have this problem. If you isolate very well the heat pad of a stirling engine, in contact with an ECat, instead of wasting heat heating the fresh air getting in and wasting heat putting out the warm exaust gases, the only way for the heat to go out is through the stirling engine, thus producing electricity… This mean that an ecat driven stirling engine, if properly isolated, should have much more efficiency… With an ecat driven turbine you must follow the classical working of putting in hot fluid and wasting the heat with warm output gas…

    Think on it: just construct a very well insulated box in which the ecat and the hot side of the stirling engine are coupled and isolated. The heat can only flow through the stirling engine, producing electricity and then the waste heat that flow toward the cold side of the stirling engine can be used for other things, like industrial processes or ambient heating… But now all the heat produced by the ecat has flow through the stirling engine, and not just a portion, producing electricity… In a standard carnot cycle turbine or in a stirling engine with a standard heat source this is not possible: a portion of the heat is always wasted to heat the fresh inlet cold air and in the warm residual fumes…

    Regards, Marco

    Dear Dottore Rossi

    Can many of Ecat-QX be mounted in one plane to an IR panel?
    That will increase efficiency of a panel and since there is no moving part can be produced quicker and last longer then and is installed simpler then engine or plumbing requiring technology.
    If Ecat-QX is made transparent for light an additional layer of light controlling foil can be added similar to LCD screen to regulate light emission from 0 to 100%. Please consider this option.

  • Karl-Henrik Malmqvist

    Dear Andrea,
    In an internal combustion engine about 30% of the energy in the fuel disappears with the hot exhausts.
    For an external combustion engine like the stirling the percentage of the heat disappearing with the exhaust should be of the same magnitude.

    However, with an E-CatQX driven stirling there is no exhaust and therefor no exhaust heat dissipation!
    Thus an E-CatQX driven stirling has a much higher efficiency than a stirling driven by natural gas!

    A natural gas driven turbine has a higher efficiency than a natural gas driven stirling.

    An E-CatQX driven turbine would have the same efficiency as a gas driven turbine with a lot of heat going out with the hot exhaust/air.

    Conclusion: An E-CatQX fueled stirling should have a higher efficiency than an E-CatQX fueled turbine!!

    For electricity production, go with the stirling. For a combined electricity/heat production you could still use a turbine if you take care of the energy in the hot “exhaust” air.

    Regarding cars, all car manufacturers are looking for electrification with batteries. What they want is a “range extender” (series hybrid) that is a compact engine-generator not bigger than an ordinary combustion engine that charges the batteries. The power of this engine-generator can be much smaller than an ordinary engine.

    The range extender in BMW i3 REx is 25 kW. Renault Kangoo has a version with a 5 kW fuel cell range extender. So there is a huge demand for this size of engine-generator sets.

    Electric cars in cold weather will have a much shorter range because a big percentage of the battery power is used for heating the air inside the car. Here is a big opportunity for a simple 5kW E-CatQX air heater. This product could be in every electrical car.

    Best Regards,
    Karl-Henrik, Sweden

  • Gerard McEk

    Dear Andrea,
    Reading your blog, it seems you are moving in the direction of domestic heating and electricity production.
    I believe that REMEHA.NL would be an interesting partner. They make domestic heating and warm water boilers. The eVita boiler generates max. 25 kW of heat and additionally 1kW electrical power using a maintenance free Stirling motor/generator combination. I am not sure if you were able to interest them in a combination with a E-cat QX. If not, I would be willing to try for you.
    Kind regards, Gerard

    Dear Andrea,

    The engine you want to build within a year, would it be for cars, trucks, trains, boats, planes, or something else (if so, what)?

    Thank you very much if you can answer,

    Dear Andrea:

    Is your interest in coupling the Ecat-Qx with a Sterling Engine based on safety certification for the small or household market? Steam systems require certification, testing and periodic retesting of the pressure vessels I can’t imagine having one in every home. However an Ecat-Qx providing heat to the home for climate control and hot water coupled with a sterling engine and generator for electrical power contained in a cute little dog house out back is something we’ll all want.

    Good luck and thank you.

    Dear Dr Andrea Rossi:
    I suppose in a gas turbine the sole area where the E-Cat can be inserted is after the compressor, correct?

    Lucio Martini:
    We are making R&D on any possible application to make an engine, which does not mean we abandoned the Carnot cycle to make electric energy.
    Warm Regards,

  • Lucio Martini

    It seems to me that you are abandoning the “Steam” option to adopt a Stirling engine.
    In theory, the Stirling cycle has the same performance as the Carnot cycle (in theory!).
    I think the solution is as good as possible if you think of running a generator.
    Warm regards.

    1- it is very beautiful to look at
    2- I feel myself like that apparently frail sail that never sinks
    3- if you observe the waves, they pile up making a tsunami: virtual particles could make such resonances by waves raised by temperatures that reach the mass of the corresponding elementary particles and antiparticles that eventally annihilate. Intriguing.
