Stirling Engines and LENR

Many thanks to ajp for posting a comment today which included this link to an article from the Guardian, which reports on how a solar installation in South Africa’s Kalahari desert built by a Swedish company called Ripasso is converting solar energy directly into electricity using a Stirling engine.

The solar plant uses mirrors to focus the sun’s energy that drives the Stirling engine, and is reportedly able to convert 34 per cent of the solar plant’s energy into grid-usable electricity (compared to 15% in photovoltaics solar plants according to the article).

From the article:

“The technology works by using the mirrors as giant lenses that focus the sun’s energy to a tiny hot point, which in turn drives a zero-emission Stirling engine.

“The Stirling engine was developed by Reverend Robert Stirling in Edinburgh in 1816 as an alternative to the steam engine. It uses alternate heating and cooling of an enclosed gas to drive pistons, which turn a flywheel. Because of the material limitations at the time, the engine was not commercially developed until 1988, when Swedish defence contractor Kokums started making them for submarines”

This article prompts the question: could the Stirling engine be an important partner-technology for LENR, and spefically the E-Cat? Andrea Rossi has recently said that while his team is finding that the Hot Cat is proving to be a promising technology when it comes to making home heating units, they have not yet been able to find a suitable way of converting heat to electricity for home power generation.

If, as Rossi says, heat can be produced at a high COP level with the Hot Cat, even if heat-to-electricity efficiencies were not terribly high using a Stirling engine, it still might be worthwhile to use some of the heat being produced by the Hot Cat to drive a Stirling engine to make at least some electricity.

Rossi has shown interest in Stirling engine technology in the past, but so far has failed to find an off-the-shelf Stirling engine that could be combined with the E-Cat. Perhaps this is still the case — but this article indicates that there is at least one company that is finding important success with the technology, and perhaps this is a sign that there is a promising future for Stirling engines.

Since all you need for a Stirling engine to operate is a heat source, and the output of LENR is heat (which can be produced cheaply), there could be an important synergy between these two technologies.

    I just saw an interesting post about a potential rival to the stirling engine.

    This invention generates electricity in a novel way. I’m not sure if it is more efficient than the stirling engine, but I believe the ecat could be used to provide the energy to power this device. It relies on the bouyancy provided when air is introduced into an inverted container full of water. The energy input comes from compressing gas and forcing it into the apparatus. The manufacturer is claiming over unity for this device, which is obviously nonsense. However if it is reasonably close to unity, this would be a big win for the ecat, since the heat from an ecat can easily expand the gas enough. to make this work.

  • Nicholas Chandler-Yates

    I asked Rossi a set of questions:

    I have several questions for Mr. Rossi:

    1. Have you considered the application of stirling engines for smaller, domestic (in the 1 kw range), Micro CHP (combined heat and power) applications? Several stirling engine Micro CHP devices exist on the market already usually with nat. gas boilers.
    such as this one:
    or this one:

    2. Has the customer of the industrial plant that is currently undergoing testing agreed to inspections by outside sources (news representatives, scientists etc.) once the test is completed?

    3. With current progress on the plant seemingly going well, how does this make you feel?

    thanks, NCY

    Rossi’s Response:

    1- Yes, this is one line of our R&D
    2- The customer that has installed the 1MW E-Cat in his factory is not a R&D laboratory, is a factory that makes an industrial activity. I have no idea what they will do inside their factory after the end of the contractual test on course, but for obvious reasons I would not be surprised if the access to their factory will be limited to the persons involved in their activity. Anyway, this is an issue doesn’t depend on me.
    Let me add also that being for sale in the market the E-Cats, it will not be necessary to inspect the E-Cat of others, since anybody can buy one and use it.
    3- Troubles have always a tomorrow, and ” tomorrow never dies” ( Bond, James Bond).

  • GreenWin

    Here is a well-made Stirling designed to burn biogas – producing 20kWt, and 7kWe from 12M(cubic) low quality biogas per HOUR. A unit like this might match E-Cat better than those requiring higher temps. It is a CleanEnergy C9G (Sweden) available today in the UK! But only for landfill biogas use. Heaven forbid anyone put this in community center, factory or municipal building!!

  • GreenWin

    Ha! Little Bessie suspects illogical programming from HIS basement. As would Sam Clemens, had he stuck around. Hundreds of His minions hacking away… and we get this?? Almost makes NIF look like a success!

  • Henry Oegema


    After reading about Stirling engines yesterday, I received
    this information on a thermoacoustic generator made in Texas. Simple, quiet and
    efficient. Look at the efficiency curve on the graph.

    Like many other good things, this is not yet in production.
    But a hot cat driving this for home use, should make for a nice compact unit.

    I think the small one is 500 w, the bigger one I don’t know.

    • Omega Z

      I’ve been aware of these for a long time. Long enough it was called junk science. 🙂
      This is interesting, but I wish they would give a better idea about exactly what efficiency to expect. Seems it should be possible to make an app calculator for input temp & ambient temperature & give a reasonably accurate efficiency rating with plus/minus range. Estimated Price would also be appreciated.

  • closed brayton exist, and is interesting for high temperature and lightweight systems, like in aircrafts.
    I’ found article on that recently… forget where.

    • Fyodor

      A lot of these systems exist but the engineering is hard and the systems are sufficiently expensive and complicated that they are only being explored for expensive and high powered systems where the profit justifies the large capital expenditure. I know that some of them are being looked at for large nuclear-thorium plants.

      I am sure that if Rossi is successful in making the Hot-Cat work reliably and mass-producible we will eventually see all sorts of long term innovation. But heat-to-energy systems are hard and complicated and difficult to engineer and have usually taken longer than planned to make and/or commercialize (if they get that far).

  • GreenWin

    A massively beneficial technology assigned “exclusively” to toadies of NASA – is the equivalent of suppressing polio vaccine in 1960. We will NEVER get an “actual product” as long as the IP remains in the hands of corrupt toadies.

    And I shall take another opportunity to disparage the programmers of our inadequate simulation. You do not know human behavior. But you CAN learn!

  • GreenWin

    Like much technology that could benefit humanitarian causes, an advanced form of Stirling — thermo-acoustic Stirling requiring no moving parts, has been introduced and then studiously avoided. This design was announced a couple years ago (2013) to little fanfare. The facts are the patent belongs to the American people via NASA Glenn. But, unsurprisingly, the exclusive patent owned by NASA (i.e. American people) has been assigned to a tiny little start up in Cleveland.


    1) Why does technology lawfully belonging to the American public get “exclusively” assigned to certain employees of (NASA) the American people?

    2) Why has such innovation been ignored by the mainstream press and, “consensus” science community?

    3) How much malfeasance at the USPTO do we need before some (even low level) practitioner of the law comes forward to defend the American public?? Is there ONE Congress-person able to muster the honesty???

    Frankly, this is further evidence of the markedly failed simulation we all “live” within. Programmers who actually know human behavior would refuse to write such sophomoric code. IMO. Indicating that our programmers are elementary at best.

    • GreenWin
    • NT

      Well said GreenWin and unfortunately for us American folks very true. Our own taxpayer funded National laboratories Sandia , LLNL, etc do the same thing with our taxpayer dollars…
      “Is there ONE Congress-person able to muster the honesty???” The short and long answer is an astounding ‘NO’ – not one with any gonads (male or female guts) in DC it seems – very discouraging leadership on many levels these days…

    • Omega Z

      I can think of only 1 reason.
      The person the patent was exclusively assigned to was one of the people involved with it’s development. I’ve noticed MIT does the same thing with promising technology.

      I would agree that said person has a right to the technology free of license fee they helped create & have their signature on said patent, But, As it was funded by tax payers, It shouldn’t be exclusive. Others should be able to license it as well.

      I’m certain that when they get around to fixing the patent process, this issue will be addressed. RIGHT?

      Yes, And I’ll be elected president in 2012.
      Nope. Didn’t happen. 🙁

      • GreenWin

        Correct Omega. If the people finance an invention — they have a right to license it. “Exclusive” assignments essentially steal IP from those who paid for it. And conveniently bury technology guv’ment doesn’t want the public to have. BTW, I voted for you in ’12.

  • Nicholas Chandler-Yates

    indeed, people that talk about a small steam/turbine system are fooling themselves, stirling is the best choice for small systems, steam is the best for large systems (power plants).

    • I’ve heard that.
      I can add that Brayton turbines are the choice for lightweight systems.

      note also that Rankine is better for low temperature, especially Organic rankine.

      the problem I’ve heard with Stirling is that they have huge wearing and low efficiency in real world, compared to rankine (of big size).

      • Nicholas Chandler-Yates

        i don’t know what you mean by huge wearing… the Stirling engine i referenced is sealed for the life of the unit with no maintenance required and uses gas bearings to reduce friction.

        • It seems they solve the problem people relayed to me…
          Or it is just eating some efficiency.

          note that for ranking there is also a problem of wearing, but some try to reduce it by using non water fuild, like organic fluid or supercritical CO2 (or like Climeon, mix both).

          It is hard to find a synthetic document on that question…
          Rankine, Brayton, Stirling, Thermoacoustic, TEG, Thermionic,
          I would like to have a synthetic comparison with temperature, efficiency, size, price, reliability…

          • parallelB

            Stirling engines have shown promise for many decades, promise that has failed to materialize. It maybe that someone comes up with a brilliant design but until it has run for a few years you don’t really know what the problems are.

            Micro turbines are relatively mature The link below mentions (at the end) a system that even uses solar heating of the gas, which tells me one could do the same using Hot Cats.


            • microturbines are still big (50-1000kW), but this 50kW would fit a car

              like on solar and wing, I’ve heard both position on Stirling.

              what I think is that LENR will change all, as now price and weight are more important than efficiency, and it have to work at 5kw (home) or 50kW (car)

              • parallelB

                AlainCo, “microturbines are still big”

                You didn’t see the video two posts down did you? A 400W complete genset in a small suitcase is hardly big 😉

                • yes turbine below 10kW interest me much, but I don’t see many off the shelves turbines below 50kW, and even below 1MW…

                  I’ve read that gas/Brayton turbines are very compact compared to Rankine, and lighter.

                  it seems Stirling advantage is that is can work at lower power.

                • parallelB

                  Agreed there are not many less than 10kW, but this is because of the market. It is simple enough to derate and downsize them. The 400W example shows how small you can go. I wonder what happened to that one.
                  I think the lower working temperature you would get from Hot Cats would downrate them anyway.

                  I would probably go for 10kW for my house to take care of peak loads unless I was still connected to the mains. Better yet would be 5 kW plus lithium battery power storage

                  15 kW
                  20 kW
                  10 kW

                • thanks for the link, especially the first review.

                  I don’t think you would need much power for a home . my 100m2 house, was runing with 6kW with partial electric heating and boiler….

                  I think that assuming you have a CHP heating and boiler, and no electric heating, you don’t need more than few kW of electricity.

                  1kW for many computers and TV, plus light…
                  biggest consumer may be the electric oven (3kW).
                  on the long temp I think that oven should be LENR like hotcat.

                • parallelB

                  I agree . As I said 5kW with a battery backup for surge would do nicely.
                  Micro turbines can be run at less that rated output although the efficiency would drop from ~30% to ~15% at 60% of rated power.
                  But this doesn’t matter too much providing the power generated can be used to drive the Hot Cats

              • GreenWin

                Capstone makes a 30kW microturbine:

          • Omega Z


            Yes. Details, Hard numbers are hard to come by with all these systems which leads me to believe they are not yet ready for prime time. If they were they would be touting it from the towers.

            Note there is a ton of waste heat available that they claim would work. Why aren’t these flying from the warehouse shelves. There Lab versions don’t yet pass the reality real world test. Pricing is also hard to get. They suggest contacting them for consultation in many cases.

            But you know what they say. Claim it will rain tomorrow everyday & sooner or later…

            Ha. I hate digital clocks. The old analog could always claim to be right twice a day.

        • parallelB

          In the past, the cylinder/piston wear has produced dust that blocked the fine pores of the heat exchanger. As far as I know, no commercial unit has been tested for multi-year continuous operation yet.

  • KeithT

    A small stirling engine as part of a home wall mounted micro-CHP (supplies mainly heat and some electricity) has been on sale within the UK since 2010, this is the Baxi Ecogen, the stirling engine part is supplied by Microgen Engine Corporation, and is volume manufactured in china.

    “The Microgen unit, developed by BG Group [British Gas] from a US (Sunpower) design, is a LFPSE [Linear Free Piston Stirling Engine] which is intended for wall-mounting; it contains a supplementary burner which enables it to meet the full heating requirements for even larger homes.

    Following disposal by BG Group in 2007, development of the Microgen unit was taken over by MEC, a consortium of gas boiler companies (Viessmann, Baxi, Vaillant, Remeha) and Sunpower.

    Each of the boiler companies has developed their own variant of micro CHP unit incorporating the MEC engine, now being manufactured in China.

    The UK variant is manufactured by Baxi, part of the BDR Thermea Group which also includes Remeha, De Dietrich and Brötje.”

    • Nicholas Chandler-Yates

      indeed the E-cat is what Stirling engines have been waiting for. Essentially a gen-set/water heater for your house that pretty much needs no fuel.

      hook one of these suckers to one of the self sustain mode domestic e-cats that rossi has been talking about recently, use any waste heat to heat hot water. Hook it up to the battery set your choice to keep the lot running.
      This is the sort of set up that will provide energy for the first settlers of mars. The power density is just higher than anything else.
      Elon musk will be very interested when this comes to fruition.

  • EEStorFanFibb

    Hot cats when coupled with another device will certainly be able to produce electricity in a reasonable fashion. BUT I think nobody will be able to buy such a setup for their personal use / homes for decades.

    I think all LENR devices for the home will have to be home made contraptions. Even if Rossi / IH allowed sale of home units, no regulator would allow it to be sold for that purpose until it was tested in an industrial setting for several years. The closest thing we’ll get to home units before 2025 imo, is municipalities buying these devices for cogeneration for whole neighborhoods. It will still be a revolution of immense proportions.

    • Fyodor

      It’s not just regulators. Getting a heat-to-electric device reliable enough for unsupervised home use is just an entirely different ballgame than making something for industrial use.

      • Omega Z

        I fully agree.
        Home heating will be available, but electric generation of any consequence will be quite a while down the road. There are multiple issues to be addressed.
        Aside from safety, There is also the issue of how we use electricity. Very little most of the time & large quantities in a very short period. Given certain aspects of the technology at this time makes it quite complex to make it cost/benefit effective.

  • parallelB

    ps. The compressor would have to be like the turbine in a turbocharged car, but the micro turbines borrow a lot from that technology anyway. You would need a heat exchanger of course but the waste heat could be used to heat the house and for hot water.
    It doesn’t matter that the efficiency is low if the fuel costs nothing.

  • parallelB

    I don’t see much wrong with simply replacing the natural gas combustion of a micro turbine gen set with hot cats. There are many designs now available, with a nice 30 kW one from Czechoslovakia.
    I suppose one would need a COP of at least 6 to be much use.

    They can be tiny. See Now two years old. 400 W.

    • Fyodor

      Natural gas can use internal combustion engines because the gas can act as both the working fluid and heat source. It’s one of the reasons that Natgas plants are cheaper than coal fired plants. Doesn’t work with external heat sources like the E-cat.

      • Nicholas Chandler-Yates

        yep need a stirling engine for an external heat source.

        • Fyodor

          Or, more likely, a traditional boiler-turbine setup.

      • builditnow

        Incorrect: The US airforce nuclear powered jet aircraft that flew in late 60s early 70s used a fission plant onboard and a heat exchanger in the jet engines. See NASA Seedlings conference around Feb 2014 (available online) where several top experts in the field reviewed the performance of a jet turbine running on jet fuel vs using a heat exchanger at a NASA conference. The performance is very close, practically identical. Hot-Cats at 1400C are ideal for jet turbines.
        The basic simplicity and durability of these turbines could make them the first choice. Airbus has offered one for LENR conversion that has an efficiency of 30% at 1000C (reported on and elsewhere).

        A micro jet turbine could be the first use of Hot-Cats as a charger in electric cars, a simple add on, no need to ever plug in.
        Expect Musk to add them to the Tesla electric car as soon as he gets some decent advice that Hot-Cats are real and give the Tesla unlimited miles and exceptional performance.

  • Alain Samoun

    Don’t forget the slingshot of Dean Karmen:

    That will be the solution for an LENR reactor to produce electricity.

  • malkom700

    Do not forget that the issue of effectivity is primary only for local installations, because the interconnected units will have practically endless effectivity. Of course, also the question of local facilities is infinitely important.

  • MontagueWithnail

    I’ve thought about this a lot myself and concluded that LENR
    probably will be the first commerical-scale use for Stirling engines, eventually,
    for small scale combined heat and power units. I don’t really expect it to be
    at a domestic level – except for in very isolated locations – because I think
    operation and maintenance will be much more cost effective at a district level,
    but for small commercial and industrial uses, isolated domestic locations (down
    to the kW level) and mobile generators (for e.g. construction sites, or
    festivals), in the single digit MWe scale.

    At a larger scale, steam turbines are going to be more cost effective for a
    number of reasons, but steam turbines do not scale down terribly well (whereas Stirling
    engines don’t scale up very well). At this scale the other benefits of Stirling
    engines should really come into their own – lower operation and maintenance
    cost, inherently safer, lower noise etc. The main disadvantage is that they are
    quite bulky and the capex is relatively high because there are effectively
    going to be 3 sets of heat transfer surfaces – unless you buy that the reactor
    itself would form the hot end, which I absolutely don’t.

    Someone else mentioned about batteries and that’s an important point, sterling
    engines don’t respond terribly well to a variable load regime (unlike internal
    combustion engines) and so some way to balance load demand – or connection to a
    grid to do the same job – would be important.

    One last point, people tend to get very fixated about efficiency. That will be
    an important point if we have a reactor COP in the single digits. The long term
    goal is to get reactors running a COPs well over 10, at which point the cost of
    the heat is tending towards irrelevance and efficiency per se is no longer a
    very pertinent consideration. It will all be about the lifetime cost (capex and
    opex) of the engine and generator, and operational considerations such as
    space/weight, flexibility, safety etc.

    • Nicholas Chandler-Yates

      i agree that Steam is more efficient at large scales, but stirling engines do not require maintenance. Modern stirling engines are usually sealed for the life of the unit, and have inert gasses inside. this results in an extremely efficient wear cycle, because unlike internal combustion engines, there is no dirty fuel exploding in them, and there is no oxidation of any of the moving parts.

      The Microgen stirling engine uses gas bearings, reducing mechanical wear to practically nil as well.
      see this video:

      you can easily see the ‘boiler’ in this unit replaced with a hot cat boiler instead.
      this is, in my mind, the perfect home heating/power set up.

      • MontagueWithnail

        I agree that Stirling engines are cheaper to maintain than other engines, which I also mentioned in my post, but they are not the only component of the system are they? We have no idea what the maintenance or operational regime will look like for the reactor itself, plus (again unless you believe the reactor will be physically built into the hot end of the Stirling engine, which I don’t) there will be a heat transfer fluid, probably a specialist high temperature liquid, with attendant high-temperature pumps, reservoirs, valves etc which will require maintenance, and will fail occasionally. There will also be a power supply for the reactor, a control system and a generator unit, all of which should be low maintenance but these things do fail from time to time as well. That, combined with the physical bulk of the overall system, the cost, and the fact that there will be some noise (although admittedly low relative to an IC engine) will not make it terribly attractive for most people to put units in their own dwellings. People are already connected to the power grid, it will make far more sense to have interconnected centralised units supplying distributed power to a local grid and heat to a few hundred homes via a district heating system. The initial capex of the district heating network will be easy to amortise over an appropriate period (where it doesn’t already exist) and it will anyway be much cheaper to have one large unit than hundreds of smaller units.

        As I acknowledged, this will not apply to every domestic property. The factors that will tend to lead to home units will be: the density of the housing, the premium on space, the per-residence consumption of energy, and the societal preference for self-reliance. I expect Americans will be far more likely to have home units than Europeans but there will be an economic penalty to pay for that.

    The difference to Kamen and the others is that this is ready now. It brings tried and tested submarine tech that’s been in use for decades into other fields and there is annual production capacity of 3GW. I’m rooting for everyone including Kamen (especially since this will get costs down) but Rossi is right to ask for products you can buy today.
    Connect a few HotCats via heatpipes to the hot end of the engine, disconnect from external power and we’ll have undeniable proof.

  • catfish

    LENR and EmDrive. Another interesting combination

    • yes, but one revolution at a time please 😉

    • Axil Axil

      I believe that these two reactions are related. They both involve the partitioning of the vacuum into positive and negative energy zones.

      Because of this connection with the manipulation of the vacuum as the ultimate cause of these two reactions, t may be possible to use EmDrive techniques to produce LENR and LENR techniques to produce EmDrive power. Now wouldn’t that be sweet?

    Segway Inventor Dean Kamen Thinks His New Stirling Engine Will Get You Off The Grid For Under $10K

  • Gerard McEk

    I believe the Ecat/Hot cat and the Stirling engine are a perfect match. The only disadvantage is that these engines are not easy to make.
    Maybe this principle has a better chance. I picked it up in Rossi’s blog:
    and combined with the Tesla motors Powerwall, than we may have an ideal power/heating unit to make you totally independent from the grid and oil/natural gas/coal supplies!

    • Ophelia Rump

      You would need the Powerwall the Hot-Cat and the Beacon 10 Stirling engine. By selliing back to the grid the Powerwall could be skipped for home use. But it would have a role for commercial storage. I don’t think home generation would get rewarded for selling the nights generation during peak hours, so it would be a wasted investment to buy the Powerwall. .

      • Gerard McEk

        I fully aree, this is just for non urban territory, somewhere in the bush, unless the price of the powerwall drops dramatically

      • Rene

        The Powerwall is viable because many legacy power companies are either no longer accepting power from home generators or are abandoning net metering. Yes, if net metering were not imperiled, the Powerwall would not make much sense.

    • pelgrim108

      Does this powerblock need cold to function? I would think that if you dont need cold than efficiencies go up if used for E-Cat.

      • Gerard McEk

        Yes, otherwise it does not work. What I have seen on the site of Lion-Powerblock is that the condensed water of the ‘cool’ side of the piston block is used to heat the house. It’s efficiency is hugely increased by the use of making both electricity and heat for house warming. The piston moves a permanent magnet in a coil and thus produces electricity. A similar design has been made using a sterling engine, where the engine piston contains the magnet and moves inside the coil.

  • Bob Matulis

    Rossi: Hot Cats to be Used for Domestic Unit — ‘Very Long’ Self-Sustain Periods in Single Units
    If the above statement is true then why haven’t they hooked up a Sterling Engine to an e-cat reactor/set-up, and pumped out Carbonless, +COP, free energy that is pumping out more than is going in. Measure the power coming out of the Sterling engine (when the e-cat hits SSM and), there is your proof that more power is coming out than is going in… (and literally no power would be going in in SSM, in my understanding of the SSM)

    I just dont understand why something like this isnt possible (hasnt been done) for Rossi and co. to put together and “prove” to the world that LENR and the e-Cat is legit? We wouldnt need the 400+ day tests, like literally they could put a sterling engine sitting on top of the shipping container, hooked up to a watt-meter, and compare it to the watt-meter that is hooked up to the shipping container.
    Yes there would be some delays with residual heat but it would show more heat coming out than going in when its in SSM.

    Time for coffee I think Im rambling.. great article though!

      They may have hooked up a sterling engine as a proof of concept that we don’t know of.

      Just assume that they have already proven to themselves their technology is working and their goal is to deliver working plants to the world (==their customers) . What is the benefit for them to “prove to the world” that LENR is real, before the reactors are 100% bullet proof tested ?

      For sure, they could prove the viability to the world anytime they like, but they are going to do that with 400 days worth of data to back it up.

      I can understand they don’t see a necessity to prove anything before that.

      I am impatient too and I fear that even after the 400 days we’ll still be left with some doubts.

      LENR will be real for me, when it provides my energy, my heating, my electricity. It will take years to get there, unfortunately.
