Is the Cyclone external combustion engine the future?

So when I first heard about the cyclone external combustion engine from one of you guys I was extremely intrigued. I mean combustion is something that happens under extreme pressures and that pressure is what makes combustion so effective. So does this engine still function like a normal engine with, air, fuel and spark or is this a whole new take on the internal combustion engine? Well lets find out.

I looked into these about 15 years ago and they were constantly battling sealing and wear issues. The water was completely inadequate for the lubrication needs and pretty much every time they ran one on the dyno or if it was in a show it would be a freshly built unit. Longevity/durability is the reason these things never took off.

[@Surestick88]

Didn't steam locomotives and a bit of oil to the steam to lubricate the cylinders and valves? Not environmentally friendly in a total loss system but if you're re-condensing the steam and re-using it that's less of an issue.

@@Surestick88 You cannot reuse the oil though. it must be filtered out of the condensing water with an oil diaper before the water can be recycled back into the boiler, so it is still a total loss oil system.

These were very similar units to those used in DoD/USAF courier trucks in the late 70s/early 80s. They could literally run on anything, and were used as everything from couriers to tuggers at several air fields. Cyclone's claim-to-fame wasn't the steam engine, but the cyclonic combustor. The centrifugal force of the high velocity cyclone, was a captive cycle for most of the particulate emissions the EPA was currently focusing on. They were working on a closed-loop Sterling model, which was even less maintenance. In the end, they lost out for lack of marketability and a restrictive investment contracts. The slow start-up time, low power density by volume, preferred vertical orientation, inflated goals, and low duty cycle, saw the project fall off the radar. In order to achieve their peak efficiency, the engine used a vertical orientation to take advantage of natural convection. Last I heard, a slightly different version of the combustor could be found in a waste oil heater... but I'm unsure if it has any relation to Cyclone. I reached out to them several years ago, in hopes to connect them with a pneumatic motor supplier from Australia... but it didn't work out, as the Aussie supplier was adamant about both NOT using his motors in combustion engines, but also not letting the tech leave Australia (although it's now used in some forklifts).

[@LordOfNihil]

steam is used in nuclear power plants to drive the turbines. its a good way to move energy around a thermodynamic system. i think the real advancement is more the combustion end (the boiler in traditional steam systems) as you can probibly hook the engine to any steam source and get power out of it. steam engines are pretty straight forward and a lot simpler than ices. you can also push the piston both ways so you can have fairly consistent forces on the crank shaft rather than intermittent like a 4-stroke. its pretty much steampunk evolved.

[@themusicgaragetmg2330]

its a steam engine steam engines are external combustion engines if you look at the "engine" they look fantastic on paper but the boiler and condenser are MUCH larger than the carburetor and exhaust pipe (carburetor~= boiler, aka where fuel is added)(exhaust pipe ~= condenser aka where heat is rejected) so internal combustion is WAY more power/smaller/cheaper, it never stood a chance

[@raykillorn4950]

It sounds like most Cyclone engine problems come from the mindset that it was "not invented here." I have first-hand knowledge of Cyclone's business problems. At the moment, they are working with interested parties to take advantage of the clean burn characteristics of the engine to turn a foreign nation's colossal waste disposal problem into a microgrid electric power solution that addresses both sanitary waste disposal and municipal power reliability with dual use infrastructure funds. Modern waste streams with large amounts of plastics burn clean in the external burn chamber. That is because of the filtering effect of the cyclonic flow within the burn. Cyclonic filters efficiently separate solids (even very tiny ones) from gasses. The Cyclone engine utilizes a cyclonic filter as a burner to provide supercritical steam for its engine. As the burn progresses, burning masses heavier than air are not allowed to escape the burn until consumed by the burning process. Similarly, burn by-products such as ash and metals in the burn become consolidated in a molten pool that drips out of the cyclonic burner/filter as an easily manageable byproduct of the waste disposal process flow. External combustion that is clean enough to meet CARB air purity standards (from municipal waste!!) is only the beginning of the good news. The engine converts 40+ percent of the heat produced in the burner to usable shaft horsepower. I can imagine that with only a subtle design modification that the burner/engine I have just described could burn powdered coal, sequester any unburned burn-by-products as raw material for industry and enable the creation of microgrid power infrastructure to ease the strain on the power grid crunch that is sure to arise from the rapid roll-out of battery-powered transportation. Cyclone has proposed a system capable of harvesting solar heat and storing it using a working fluid that resists freeze-up of the system when it is offline and keeps energy as 1500 degree F heat in insulated underground containers. They suggest designing heat storage with enough capacity to provide 5 days of off-line power. Of course, a solar system of this kind can have a cyclone burner.

[@melchiorhof6557]

Uh... If you're going to power an electrical grid with steam, maybe a turbine would be a better approach for heat-to-mechanical energy transformation than a 5-piston radial engine.

I think you've put too much faith in what sounds like the voodoo-science of a "cyclone burner", and I'll continue to believe that unless you can provide some substantive information about the actual design and functionality of "cyclonic filters" and "cyclonic burners". 99% chance you're missing something very important, something that makes the system your speaking of nearly impossible to sell when all the facts are known.

Also steam turbines are clearly better, more practical and are very well established and mature technology at this point. Very interesting comment. I have been wondering for a while if it's possible to cleanly burn waste. We could theoretically do it with human waste too, by filtering it out, removing the water and burning it in a superheated furnace. Given enough air being blasted in, anything becomes a fuel just about. Check out the mad Aussies with their turbocharged burn barrel lol. You wouldn't think wood could behave like jet fuel, but a couple of bogans in a shed proved that wrong.

Giant steam powered turbines are currently in service all over the planet, providing electricity for the masses. The super heated steam is created by coal, natural gas, nuclear plants, and probably some heat sources I haven’t included. All USN submarines and aircraft carriers are powered by electricity created by steam turbine generators. The steam is created by the nuclear reactors. Steam power never died, folks. It just found new employment. 110 years ago a steam powered car was much faster than gasoline, but many factors like road conditions made speed a moot point. In 1938 a British steam locomotive named Mallard went 126 mph. A record never broken (for steam) to this day. More than a few comments made in this video made it clear that an informed awareness of the history of steam power, and the current use globally, was sadly lacking.

[@eliyahzayin5469]

From what I've read, the inventor had very little understanding of how to actually make a viable engine. Besides the water lubrication issue others have mentioned, the original design linked the pistons to a freely rotating plate rather than a plate aligned with one of the pistons for radial engines as is common practice. This added extra vibration and mechanical loss. Overall, my impression of the Cyclone engine is that it's either a scam or made by a well intentioned person who really didn't do their research. What especially disappoints me is that there are several modern steam groups that are much more reputable (I.E. actual research and, in the case of DLM, actual prototypes and production machines) but seem to have little notice.

[@gordonjohnson405]

It is a Racine Cycle Engine, similar to a Stirling Engine. It's not new. It gets its "modern" power levels by using deionized water. For the science-challenged, deionized water is water with all the minerals removed. Removing the minerals allows the steam to be super critical with a lower energy input. Deionized water, however, is a very powerful base. It will absorb the minerals from anything it touches. This means it will dissolve almost anything you put it in. Cyclone sold their waste heat engines to a number of power generation companies. However, TPTB do not want flexible fueled engines. They want no engines for anyone but themselves. On the engineering side, the material science to allow the engine to cost-effectively circulate deionized water without being dissolved simply does not exist. All the technologies that can do it are too expensive to scale.

Carbon steel and cast iron rust much faster than in salt water. Stainless steel acts like carbon steel near salt water, and seals and gadgets need to be made of silicone or Teflon or be eaten away in short order. Using high-temperature water as a lubricant won't work well for any materials I ever encountered. I can't think of any that wouldn't be better off running dry than in 1,000 F water.

[@driverjamescopeland]

Valid point... and Teflon wouldn't work (as least, not for long). Even Viton seals wouldn't work. When you get supercritical steam in/around moving parts at those pressures, it will eat nearly anything. Teflon, in it's microscopic form, is made of tiny flakes, and uses water in itself. Even after curing... at those pressures with steam, the shock waves create microfissures and it simply flakes off in short order. Furthermore, the various stresses that occur inside rotary piston type layouts, necessitates a high degree of lubrication. I'm with you... even dry WSO² in dry powder form, with all it's high maintenance, would be a better solution. Even if they didn't use salt water... the cavitation alone, would cause significant issues.

Explode fuel to make movement but heat and light not being used. I’m serious that you could potentially make a glass engine, fused silica or quartz , fused silica have a melting point of 1900 degrees C and can be cut very accurately and doesn’t expand or contract much at different temps and you could use a high rpm engine in the right circumstance to create useful light and energy from movement And use the heat too .

Been following this for some years to me it’s a steam powered radial engine last I heard it was successful used as a generator

[@boydgrandy5769]

A couple of things jump out immediately to explain why this design may not fly very far. The heat/steam source has to withstand 1200psi and 568 degree F. That requires serious thermal and mechanical components to contain and control it. That means that the total package is going to be massive, with respect to an IC motor. Once through use of superheated steam is inefficient, as the cycle can only extract some of the energy from the steam. You would have to use some sort of stepped low pressure piston set(s) to get the most efficient use of the steam energy (the OD of the LP pistons would increase from set to set to allow the HP exhaust steam from the first to act on greater surface areas as the pressure degrades. Even then, to maintain a closed cycle, the unit has to have an efficient condenser/heat sink design to return the exhaust steam to liquid, potentially throwing way a big chunk of the latent heat of vaporization, and again increasing the mass and complexity of the engine and its power source. Maintaining a leak free closed system is going to require that the seals and bearings of the engine must be of materials that don't wear and are not affected by extreme temperatures. Steam/water lubrication of rotating or reciprocating equipment to date has never been able to achieve that.

[@YouNameItGaming]

Only way this would make sense in my opinion is if they used the superheated water state to drive a steam turbine. Reciprocal pistons are just too inefficient, and you're never going to get sufficient lubrication with water vapor. If it had it's own pressurised lubrication system, that wouldn't work either as you would inevitably see condensate making it's way past the the piston rings and contaminating the engine oil.

It's not been 10 years, it's been 200. Supercritical boilers are used to generate power. You have to have temperatures above 374c and pressures above 220 bar. This is the first reason they are not used in cars. Old steam cars used flash boilers. Usually a coiled pipe is heated and water pumped in where it flashes to steam. It's light, quick to start and if it fails there is little steam volume to explode. So a lot safer. Supercritical boilers are the worst possible case for safety in a vehicle. Worse than a normal boiler. As all the water in the system if ruptured will flash instantly to steam as its pressure drops. Meaning all the water in the system will blow it up. And it's at at 3 time the pressure of normal boilers. Meaning you got to have some serous seals and very well made parts. Amd any failure could very bad. The video is also wrong saying it's ar 1100c. Steel would give way and the thing would be glowing white hot at that temp. It's only theorised running at hose temps and nobody has made a boiler thay does because of the material requirements. The engine is not anything special. Just a radials steam engine. Alow me to doubt how long it will last with water as lube. There are good reasons engines use hydrostatic bearing. It's performance is expected for an engine like that running at high pressure. It's probably very inefficient for a reciprocating steam engine. Only having one expansion of the steam. Triple expansion engines were not built for the fin of it. There needs no conspiracy why this has never been a success. It's inefficient, dangerous in a vehicle and would be difficult to fuel with solid materials.

[@808bigisland]

@Edward Elizabeth Hitler Outgassing H2...Hydrogen embrittlement will kill the stainless steel way before you reach 1100 operating temp. Water in the crankcase is a bad idea too. They built a bomb.

[@martinrieger5822]

F not C. Single stage can be efficient, just not under full torque. See uniflow steam engine. This is Rankine cycle and is only efficient in super critical configuration with high expansion ratios. It is the condensing and vacuum raising equipemnt that takes up volume. 1/3 the power is below atmospheric to get the efficiency. Super critical CO2 enclosed Brayton cycle might be a better choice, simple will get to internal combustion like efficiency, dual will be a little better but needs more support equipment. All this steam engine takes up more space than an internal combustion engine by about three times. Supercritical CO2 is in modern use for bottom cycles on internal combustion engines right now and gaining popularity as it is half the size of the steam plant. But we are looking at the 15MW range. Supercritical CO2 scales down better than steam.

[@larrymanning5925]

[@Peasmouldia]

The engine bit is not much of a problem, it's the boiler and plumbing that holds back further development of the steam engine. Super heating steam under the high pressures needed is really only suitable for a stationary or stable application, like marine engines. Only real advantage is using poor quality fuels, but then you're producing a lot of pollution.

[@daemon.running]

Aside from the fuel, it looks like a radial airplane engine. Biomass derived ethanol produces a higher amount of greenhouse gas than gasoline, as does biomass derived diesel fuel. Producing ethanol to mix with gasoline uses more energy than just producing gasoline.

[@scotthodgins7975]

Ok, this looks all fine and dandy, but there are several massive safety issues. 1) how do you heat the water to 1000C safely? 2) once heated, how do you make certain that this very high pressure gas doesn't violent escape? Pretty sure that steam at 1000C is at a very high pressure, and that any engine failure would be on a scale resembling the Challenger disaster. And 3) even if you somehow prevented a catastrophic failure in any of the lines/engine parts, the pressure might be strong enough to cut steel, and the sheer temperature is definitely lethal.

[@boxcarthehusky420]

As an advocate researcher for advanced steam The cyclone engine is interesting but its designer had little understanding of steam technology so the likelihood of it taking off is slim. Poor lubrication and other problems. If you're really interested in external combustion technology for the future then I'd recommend Mackwell Locomotive Company here on KZbin and the Steam Automobile Club of America on the web. Mackwell is working to sell modern steam locomotives and traction engines down in new Zealand and the SACA has an active forum with people that have built their own and worked on steam cars. I could go on and on but all I can say is it's technology that needs to be brought back.

[@sandervanderkammen9230]

Harry Schoell was nothing but a crook, a con man... Cyclone was never a legitimate company and all of his prototypes were fake, merely props to scam investors. Unfortunately the limits of the Rankine Cycle and the Laws of Thermodynamics will prevent steam from ever making a comeback... it offers no advantages over ICEs and several major disadvantages that prevent them from ever being commercially viable again. Chheers!

[@SirFency]

what is initially heating the water up to those high temps?

[@b.snoodleman5864]

Heating water to make steam for the purpose of turning it into mechanical energy is incredibly inefficient on any scale and at any temperature. More than likely the reason for it's disappeared is they realized that your typical modern diesel engine cost's much less than what they could make the cyclone for and it also makes much more power on much less fuel, and is more reliable. Same thing with the Stirling engine

[@hydeparkist]

As far as i know almost all power plants run on steam turbines with over 50% thermal efficiency.

[@wickedcabinboy]

It's a steam engine. No amount of word play can change that fact. Yes, fuel is burned to heat water and convert it to steam. And this is done outside the pistons. By that measure, all steam engines are external combustion engines - aside from nuclear powered steam production. Weight and complexity are significant factors. One must transport the fuel and the mechanism for burning that fuel as well as the mechanism for transferring the energy to water, turning it into steam - let's not forget the water tank. Then that energy must be extracted from the steam and converted into mechanical energy. The internal combustion engine is simply much more efficient, converting liquid hydrocarbons directly into mechanical energy (and heat). This eliminates all the machinery needed for steam production and the weight associated with it.

[@richardking6066]

I'd be very nervous of steam at those sort of temperatures! Potentially good as a static engine, or maybe in a battery hybrid vehicle?

If it is a monotube boiler, like most of the evolved steam cars of the early automotive era had, there is very little volume of water to cause a boiler explosion. Unlike the epic detonations the firetube boilers in steam locomotives were known for.

I believe this thing is an impressive feat of engineering but the biomass stuff is just too good to be true. If bio fuel can work of external combustion it would worked for internal combustion a long time ago. Heat water up to 1000 degrees require a lot of energy, biomass need to be processed to become extremely energy dense kind like petroleum, and that process require a lot power to do.

[@bobcornwell403]

The problem isn't the engine. It's the steam plant needed to power it. It needs at least a boiler and a condenser. And neither of those are very compact or very light. When measuring the power to weight ratio, all must be taken into account, except perhaps the fuel. Internal combustion engines rule not so much because they are all that thermo-dynamacly efficient, but because they offer the best power per weight ratios.

[@warpedweirdo]

Uh, no, that's not the real question. The real question is, are you one of those people who believe over-unity machines are possible? If so, you need to realize that your brain isn't well-suited to evaluation of complex systems. There's ALWAYS a gotcha, something you've missed, something that's eating up an unexpected amount of the energy put into the system. Better minds than yours over the millennia have tried and failed to come up with a way of manipulating various forces to produce energy from nothing. They have all failed - every last one. If over-unity is possible, you'll know it by the end of the first simple experiment. If you have to look for points of inefficiency, things to tweak, adjustments to make to try to push a system over the break-even point, you've already failed. A successful system won't try to "bend" the rules or find loopholes in the laws of physics. No, a successful system will completely trash the laws of physics, and will be able to summon massive quantities of energy from nothing by manipulating / changing the underpinnings of reality. Losses from friction, heat, or whatever won't be an issues because the sheer volume of free energy on tap will render these meaningless. A successful gravity-based system will manipulate gravity at will with zero effort. You'll essentially be turning gravity on and off as needed. Do this, you'll also have invented an anti-gravity device that will revolutionize EVERYTHING. But wait, there's more! Gravity isn't really a "force" so much as a warping of space. You'll have figured out how to warp space on demand with zero energy input. Hm.... Imagine all those scifi stories made reality. Imagine being able to create a wormhole without any of the adverse effects normal physics predicts would arise from more conventional methods... You could travel ANYWHERE in the universe, near instantly! Imagine a new super weapon - a mini-wormhole that siphons energy direct from the sun to a point on the planet of your choosing. SCORCHED EARTH! Want to make the whole earth blow up? Twist gravity enough that the core of the earth becomes extremely heavy. Earth will implode. Tune that implosion correctly, maybe the earth will go "supernova" through fusion. Or maybe just suddenly return gravity to normal, and all that highly-compressed material will spring back, tearing the world apart. A successful magnetism-based system will turn the magnetic force on and off for electrons and protons, at will and without the addition of any external energy to the system. The energy such a system could unleash would be... INSANE. Who needs heat and pressure for fusion when you can simply tell protons to ignore magnetic forces? Your first experiment would likely produce a massive KABOOM. Or a micro black hole? Hmmm..... You get the idea, right? The universe becomes your plaything when the laws of physics can be twisted, amplified, or shut off at will. Better be careful though; it may be that you're achieving this through manipulation of universal constants in a local region. What happens if there's a slip-up, and the local change becomes universal? Goodby universe as we know it! More likely though, you'll simply die on your first experiment as normal matter encounters incompatible altered reality.
