@@marsfreelander5969 1 Gallium arsenide is the semiconductor that works best at high temperatures, and is protected by an infrared mirror and likely a vacuum gap. The back side could also be cooled by the incoming air. 2 Since when do bunsen burners and gas ovens have trouble starting in winter? This will much more reliably start in cold weather than a piston engine, and can help warm the batteries in a hybrid vehicle. 3 A modern burner combusts fuel much more completely and cleanly than the explosions in a piston engine, there is a constant flow with no moving parts in the way. A piston engine is much more vulnerable to fouling from impure fuel. 4 No more so than any other vehicle with a fuel tank. 5 Like a sodium vapor lamp it is likely contained in a chamber. When you turn off the burner it cools down.

I'm no photovoltaics specialist, but I worked in a lab at a university where the people next door worked on micro-scale heat exchangers, and one of their projects was related to recovering waste heat from Concentrated Photovoltaic Cells (CPV), a system where a relatively cheap, large Fresnel-type lens diverts sunlight into a relatively expensive, small PV cell. The problem with that is that the cell efficiency was inversely proportional to its temperature, which is why they were trying to match these tiny heat exchangers with the tiny PV cells and use that heat to convert alcohol and plant oil into biodiesel. This engine obviously works at high temperatures. Low-Pressure Sodium Vapor lamps work at about 300°C, and the assembly seems too compact for meaningful insulation, so these cells would be working at high, temperatures, and therefore at lowered efficiencies. I'd wait for independent confirmation of these numbers before believing these are even in the correct order of magnitude.

but actually has zero similarity because there is no chemical reaction besides the combustion that produces heat. fuel > heat > light > electricity VS fuel > electricity. I don't know how the plan to extract so much heat from combustion gases though near needs to move from the gas to the sodium, so the exhaust gases temperature will be above sodium vapor temperature (260°C/533K) if you want to extract lets say 90% heat you need to have a heat source about ~5000 C/K. It sounds like using exhaust gases in a hybrid car would hardly produce any sodium vapor or only with extremely low efficiency

Lithium Air is said to be able to hold 12,300 watts per KG. So yeah. That is outstanding! I've already said TPV cells are the future. Or a part of it. For some applications. MIT just made some that capture heat at 2,000 celius, get better with more heat, and have more than 45% effiency. Basically the same as our best turbines! I say the future as in... The future is TPV cells plus nuclear or in ten years fusion! Sadly... I am super skeptical. Feel like the DoD would be on top of this. Just use sapphire... Oh yeah that is a great choice. So plentiful. Pretty cool if true, and I bet a ton of applications could benefit from this. TPV cells need more research. We waste so much heat, and potential energy. Having a part that captures that into electricity with no moving parts is a game changer for at least industrial purposes.

The exhaust gases carries out energy from the system in 3 forms. 1) Sensible heat, expressed in the temperature of the gases, which the thing will try to recover as much as possible (but no chance to recover fully), 2) Latent heat: any fuel with hydrogen content mixed with air and burned will produce water molecules, and there is significant energy absorbed just in the process of water vaporization (not stored in temperature but in the gaseous state), and this latent heat will be lost unless we have a condenser, 3) Kinetic energy of the outgoing exhaust gases, which could be partially recovered with yet another device, a turbine. I see too many conversions needed to even considering a 60%+ efficiency.

Is your furnace a jet or an "internal" combustion engine? Or are neither "engines"? (Producing heat is a form of "work" or is only force/motion "work?") In a rocket, combustion occurs in the nozzle to accelerate the exhaust for thrust as it leaves the nozzle. In an ICE car, the values are simply little doors that open and close for inlet air followed by exhaust. Actually more of a "digital" or step-by-step combustion/exhaust cycle rather than a more analog/continuous flow-controlled system.

I woke up in the middle of the night once with an idea for using waste heat. I googled, and unfortunately, someone had beat me to it (at least in a lab setting, I found a paper on it). Basically you use piezoelectric fins as a radiator, turning the movement of heat from the heat source to the ambient air to generate electricity. Basically it's the same technology that we use to turn thermostats on and off scaled up. Probably would add a lot of weight, so might not be worth it for cars and such, but another way to deal with converting waste heat to electricity.

The Vehicle Research Institute at Western Washington University created thermophotovoltaic power generators in the late 1990's using the technology and cells created by Dr. Lewis Fraas. The technology used gallium antimonide cells arrayed around a silicon carbide emitter. One of the national labs, Sandia (?), tested the cells at over 40% conversion efficiency vs. high grade solar cells (1990 tech) of 18% (or ~31% 2020 tech). A significant challenge is that the high temperatures, roughly 1700 k, needed to get the silicon carbide to emit photons is located within 20-50 mm of the cells which probably don't function above 400 C. Cooling the cells and recovering the lost energy is a significant challenge. The team created prototypes a bit larger than a hot pot or coffee maker that generated up to 2 kW (~2.7 hp). Eight of these units were installed in a vehicle, Viking 29. The units produced less emissions and were more efficient than a Honda genset, but not so much that it made sense to invest in a small fab plant at $100 million (1998 US dollars). Another challenge arose--physicist and engineers in this space tend to talk about efficiency a bit differently. The team found that the physicist were subtracting all of the known losses from 100% rather than the ratio of output energy to total available input energy. One has to be very careful about quoting the efficiency of these powerplants, because it is likely that the total losses haven't been properly accounted for. The early ceramics would fail after 20-30 minutes of operation. The technology does work and its amazing to directly convert chemical energy to electricity.

So many issues with this thing I don't even know where to start. The pollution alone would be extremely difficult to control. It reminds me of cheap Chinese diesel heaters, actually. * Pollution. There is no way to fully burn the fuel across a swath of power levels. They might be able to fully burn the fuel at a particular power level. * Backpressure from dealing with exhaust products to remove unwanted byproducts. * Efficiency of 60% with a hot exhaust? Not even possible. And 80% combined-cycle? I don't think that's possible either. * The high temperature of the system will greatly shorten the equipment lifespan, let alone the solar cells. * Build-up of byproducts on heat exchanger surfaces. * Multiple conversion steps... another nail in the "efficiency" coffin. The biggest red flag is having multiple conversion steps (fuel to heat, heat to light, light to cell, cell to electricity) and still claiming extreme efficiencies. That gets into "sell me the Brooklyn bridge" territory. I don't think this thing is real. -Matt

Fuel cells work through combustion as well. It's just that the combustion reaction is facilitated by an electron exchange across a dielectric membrane. Recapture of waste heat from fuel cells using Sebeck units improves efficiency. Using thermo-optical conversion through a narrow band material would allow more of the heat to be recaptured using the photoelectric effect. I have a hard time believing the 80% efficiency number, but it is a good idea.

The problem might be in getting a high enough temperature from the exhaust to, more or less, fluoresce the sodium. Anyone interested in working on the idea might want to try an old school automotive mechanics tool called a "vortex tube" to provide an incredibly high temperature air flow to heat the sodium.

Electric hybrid cars need small efficient generators as range extenders so they can have small batteries for day to day driving without range anxiety. Attaching it to a big clunky piston engine would defeat the point. Your typical car engine sends about a third of its energy out the radiator a third out the exhaust pipe and a third to the wheels. If the predictions are right tis will be more effiecient by itself.

Look at each step. Combustion: Air with 20 % oxygen is mixed with assume a gas fuel and burned. It's volume is greater then the air and fuel combined by a significant ratio so it will push the air and fuel gas out of the combustion section. The solution is a vertical mounted system where the less dense hot combustion product have buoyancy in room temperature air. However the exhaust and still burning fuel and air will either speed up and create more drag or the area increases. Radiant, and convection heating occurs heating the container of the combustion. That heat needs to be conducted, radiated, and convected to a heat sink. In this concept the final means of moving thermal energy is by radiation of the sodium at 589 nm wave length. This can only occur, with neither of the other methods being significant, if the gap in which this occurs in a vacuum and the surface is pure sodium. Table salt melts at 800C and sodium at 98C. Most efficient temperature is 300C. The salt needs to react with something to combine with chlorine being a gas that is removed by the vacuum pump. The only way of obtaining pure sodium. The sodium a liquid at 300C need to be a a porous ceramic vessel with sodium wetting the outer surface completely yet held in place by surface tension. There will be losses because something has to hold this assembly in place and achieve a vacuum. The voltaic Germanium semiconductor devices will never by 100 % efficient. however; the conversion of heat to electricity occurs in a gap between the terminals at different voltages. Physical features, so some fraction of the surface seen by the radiation hits them. The germanium is going to be heated by the radiation not converted into electricity and the also heated by the current. The combustion gases lowest temperature is about 300C so that the radiation is sufficient to make electricity. The hot gas enters the heat exchanger that is likely a cross flow device which is significantly less efficient than a counter flow heat exchanger. (the image) The inlet gases are heated cooling the exhaust gas. Buoyancy is the pump that moves the gases through the system. The hot inlet gases are now also buoyant but less then the average combustion gases. More resistance to the flow in the system as the inlet is below the then heated inlet gases. Shut down is another problem because the vacuum must end and the chlorine returned and combine with the sodium to make salt. I do not think they can achieve the efficiency predicted. My guess is that they didn't calculate all the losses and energy to needed to set the conditions like vacuum. I had spent 20 years supporting Electrical engineers and know that the minor losses are not included in the models used to design circuits. This didn't improve significantly when finite element is used to design the circuits.

As it is we need to cool the aluminum engine blocks to keep them from melting. At these lower temps, you'll need to find a different material to glow and of course the appropriate PV material. You're essentially down in Peltier element territory, and while I've long wondered why we don't strategically strap peltier elements to car engines to recapture heat energy as electricity, I think the overwhelming answer is that you can't put them close enough to the heat to be effective while keeping the engine easy enough to manufacture.

I'd think the more efficient you got the conversion the less that would be an issue... you are converting the heat to light, then converting the light to electricity. The more efficiently you do that the less waste heat you have, and on a moving vehicle you could add some air cooling. I think you're right though. Managing that heat is going to be critical. I really didn't get an idea of the scale on this... I know that, with the exception of some low speed concept vehicles you can't power a car with solar panels for continuous travel (day/night issues aside). This is 4x as efficient as regular solar cells... but you'd still need pretty significant surface area for the cells, although obviously you can fold them in ways you can't fold a panel you want to catch the sun.

I do love the thought of merging it into a traditional combustion engine.

It would also mean, depending on how much heat is absorbed, that your cooling system doesn't have to work quite as hard when the battery is being charged from this system.

pn junctions are inherently thin so that most of the light passes through without exciting electron-hole pairs. The bottom material is mostly reflective so that the light passes back through and generates more electricity. The reflection coefficient is 90% or so. If the reflected light excites more sodium, then a little less than half is emitted toward the photocell again. The rest is absorbed by the heat exchanger surface and converted back to heat. This (sufficiently) hot surface does excite sodium, but it also emits significant blackbody radiation to be radiated away and to heat up the photocells and reduce their efficiency.

Very true. You could channel the incoming air stream through heat exchanger fins on the back of the PV cells to keep them cooler though, and it would also act as a preheater for the air. Also, these newer PV absorber semiconductors have amazing absorption coefficients - unlike silicon which needs 150 micrometers to absorb most of the light, germanium carbide only needs to be 15 micrometers thick. They will get really hot though, even with cooling, so like others, I really doubt these efficiency figures.

The layers would be laid on a mirrored surface, so light reaching the mirror is reflected again towards the different layers and hence increase efficiency.

Practically speaking, fuel type will be of critical importance. Pre-circulation of fuel (as in rockets), can get you pretty low heat loss at the cost of only being able to print it, if that. And without pre-circulation - as maybe with solid fuels - you will lose efficiency. Also, how the fuel burns will make a difference. Any build-ups on those complex interior heat-exchange surfaces will degrade efficiency, and possibly force unforeseen wear on the exhaust system. Also, super-efficiently tuned-bandgap gallium or germanium or silicon or whatever seems a bit of a hand-wave. Let's actually see it. Lots of devilish details lurking.

The problem, assuming the claims are valid, is that automotive engines have highly variable power needs. This system seems likely to be tuned to a very specific power output level to achieve its very high efficiency. That is the opposite of what a car needs. At best, in a car, is you use this as a means of recharging a depleted battery array. At that point, this power system is in competition with fixed point public utilities. So instead of comparing its efficiency to a cars IC engine, you should be comparing it to the efficiency of grid scale coal, natural gas or nuclear power plants.

Sodium light has a color temperature of 2200K. This means that the Sodium needs to have this temperature to be able to emit light, (or if electricity flows through the sodium gas in a lamp at a lower temperature 900K, this is a different principle were electrons are knocked out of orbit creating a photon) .The glas tube needs to be even hotter due to the thermal resistance between the combustion chamber and the Sodium compartment. Melting point of Quartz is around 2000K, wonder how they fix that. If you want to reuse the heath from a combustion engine (40% power; 30% low temperature heath from the cooling system ; 30% heath from the exhaust at around 1100K) you need heath of at least 2200K, this is not the case for a combustion engine. In general the higher the combustion temperature the more mechanical energy can be generated. But... there are "no" materials available with high melting temperatures that can be used for (transparent and other)parts. The principle could work but I can't think of a solution to have a colder quartz tube sandwiched between a much hotter combustion camber and sodium compartment, while maintaining a good transparency for the 580nm Photo voltaic cells don't like high temperatures, sitting "close" to the sodium compartment requires a solution.

Thanks for covering this Ricky. As micro-turbine gas-electric generators already are capable of about 70% efficiency, are very compact and simple, why not use them instead combustion photovoltaics? In regards to your concept of photovoltaic ICE exhaust power recovery, I'm thinking that if you were able to recover 50% of the waste energy from an ICE exhaust using photovoltaic generator, you would be recovering about 15% of the total engine thermal losses. Having worked with large Exhaust heat exchangers (stack robbers) to capture waste exhaust heat, but due exhaust restriction and back-pressure reducing engine power, we typically only recovered about 30% of exhaust heat. If similar was the case with photovoltaic recovery, you would only be recovering about 15% of the waste energy in the exhaust stream, and something like a exhaust power recovery microturbine, adapted from a turbo-charger to drive an electric generator might be as efficient and less expensive. BTW: Back in the 80's when I was working for in the Oil and Gas Industry and dealing with HPS and Mulit-Vapor lighting systems, the thought of using high temperature combustion gas to produce combustion based lighting using a multi-vapor tubes for remote off-grid locations occurred to me. I mentioned it to some engineering colleagues, and we estimated the efficiency could be considerably higher than electrically excited tubes but the maintenance, cost and complexities of producing such a system would likely be practical and affordable, plus having combustion sources in flammable environments is not suitable.

Highest photovoltaic efficiency is 45% for multijunction cells. Getting 90% is just wrong.

That’s because you have multiple layers for different wave lengths each interacting with one another, the top layers shielding the bottom layers, different conductivities, multiple junctions etc. It’s very hard to get the best efficiency at every color or light the sun emits and you always end up losing a lot of it. But here you have a single monochromatic source with a fine-tuned single high-efficiency cell. I’d say it’s perfectly possilbe

Yeah quantum efficiency (not a buzz word, actual term) at peak wavelength of photo voltaic cells are already over 90%…. With the caveat of that’s photons inside the semiconductor, there’s still the hurdle of getting them in due to huge refractive index differences, but not physically impossible

On the internal combustion engine idea the Catalytic converter creates lots of heat while catalyzing. Using that waste energy would be awesome. Im sure it would be possible to pull the heat from the cooling system and air conditioning and concentrate it too. Imagine how small an internal combustion engine could be if it were 90% efficient having the extra power made into electricity to assist driving the wheels.

Technically the moving parts are the downfall to any internal combustion engine, first they are parts that have to be made and to really tight tolerance, second they wear out and fail if not maintained correctly and third each and every moving part takes energy to make it make it move so the moving parts in an engine are technically the number 1 thing hurting combustion engines, however, what's in this video is a bunch of hog wash and won't work efficiently like they say it will.

@@orionbetelgeuse1937 That is true, but note: If you make cheap parts you shorten the maintenance cycle and if you been to a repair shop recently, you might not like to 10* that cost even if the parts were free. So as a species we kind of grown out of cheap parts half a century ago, by virtue of maintenance costs and by pollution standards. Which means car engines are too expensive to be ideal. Which is kind of why tesla can compete on price with them even though their supply chain is still in its growing pains phase. Now this kind of thing would make for a cheap range extender, that could allow electric cars to from BEV to hybrid with virtually no complexity gain and be actually cheaper than before. (since you dont need nearly as big a battery if you have a range extender)

Oil companies aren't going to like this since it would mean you need to burn ~30% less fuel to get the same job done. Also, burning stuff works almost equally well with all fuels, which means a convenient, reliable and efficient way to convert heat from any source into electricity would blow the doors wide open on alternative fuels. Right now, alternative fuels are limited to what is compatible with existing engines since achieving efficient combustion requires very precise fuel-specific tweaking, much of which mechanically baked into the engine. BTW, if this stuff actually works as advertised, it could replace turbines in all thermal power plants where the primary coolant loop can run hot enough to make sodium incandescent. Getting 30-50% more output from nuclear plants, molten salt solar furnaces and fusion reactors if those ever become real wouldn't hurt.

Burning things more efficiently is the game, like diesel being the cleanest fuel for a truck, while also giving enough power for you to pull anything. After all, there are projects to create biofuels to replace the stuff coming out of the ground.

The problem with your last idea of using a traditional ICE and capturing the waste heat to run the sodium cell is the exchange of heat would be too slow and the ICE would overheat and seize up. I don't think you could get sufficient heat removal from the engine and still make the lightcell work. Standard engines operate at 200F I'm not sure what the temperature to make sodium glow is, but I bet it's much higher than that.

While I am very, very sceptical about this "Solid state engine", the idea of creating monochromatic light from heat and converting that light with a fine-tuned PV cell is interesting. However, as a heat source, concentrated sun light seems more reasonable. No exhaust means no energy loss due to still warm exhaust gas.

TLDR: In a nutshell, turns out, we can capture heat as specific wavelengths of light. We only know how to efficiently capture specific wavelengths (so far), so to achieve this, we funnel energy into a system which uses heat to emit those specific wavelengths. This emission, in the form of photos of a specific frequency, is absorbed by photovoltaic panels. It is my belief that THIS IS the way forward in general, all around. We waste ENOMOROUS amounts of energy because we don't have general wavelength capture. turns out, we just need to find clever ways to funnel energy into conversion processes (in this case, chemical reaction based) that generate narrower bands of wavelength, in order to fight entropy. The general concept here is REVOLUTIONARY. Forgetting about the "solid state engine" idea specifically, the more general principle IS INCREDIBLY useful and should play a role at all levels of Electrical Engineering going forward. Entropy can be outsmarted.
@Patiboke
@Patiboke Месяц назад
Interesting, but do we need this? You can convert heat directly to electricity, if it is hot enough. Plasma temperature. Blow the plasma through a ceramic tube in a magnetic field. This will separate the + and - patrs of the plasma. A little downstream you have electrical (conductive) connections in the tube. There you are, a DC power connection. I don't know if the efficiency is better or worse than this but it is one step less.

I think the reason FuelCells haven't taken over for ICE is the energy loss in H2 production. It's either made from natural gas or with electrolysis. Both have a significant energy loss in the process.

It makes sense (based on law of conservation of energy) eliminating mechanical pistons & electric generator with light & photoreceptors.

Honest to god, swear on everything, I haven't been paid for this or anything related to them, in fact....i PAID them 80 or so dollars for their razor, the just...regular angle? medium? something like that...its just their standard one they had about 1-2 years ago. It is hands down the best razor i've ever used in my life. Any time they sponsor a video I make sure people know that it is SO worth the money you pay for that good of a shave. You wouldn't think it would make such a difference, (angle precision and blade depth)...but try it, it does, and the best part is replacement blades are SO dirt cheap that if you wanted you could change blades every couple days and still save money vs a "modern" multiblade razor burn creation device. ^_^ oh, i should also mention, i've used multiple brands of multiblade razors over the years, shick, gilette, etc, i've used straight razors, i've tried other safety razors, but nothing came close. closest was probably straight razor, but stropping is a pain in the arse. If you dont know how to, you may want to look up "traditional wetshave" technique, because that's what you're supposed to do with these to get the most out of them. You'll still get a good shave using barbasol, but if you want to know what its supposed to feel like buy good shave soap and do it right. It's a joy.

First of all, thank you for your videos. They are extremely interesting, I really like them. Regarding your idea about enhancing the yield of a reciprocating engine heating sodium until it glows, consider capturing heat at the exhaust pipe level rather than the combustion chamber. This approach avoids diminishing the mechanical energy of expanding gasses. High-performance engines, especially those with high RPMs or turbocharging, have exhaust pipes that get extremely hot, sometimes glowing red. By utilizing this waste heat, you can harness additional energy without compromising engine performance. Just a thought.
