      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.

    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.

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.

    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.

    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 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.

In many cases we only go as far as we need to go to get a system to work. Then we get used to working within that system instead of looking at ways to make large scale changes. This seems to be partly the problem of industry.

      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.

    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.

    Now I understood the context of bandgap and photoelectric energy. What if we made photovoltaic cells (for roofs, not light cells) with multiple layers of photoelectric materials, each having its own bandgap? The layers would be thin so unused light can be captured by the layer below with the corresponding bandgap. 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.

    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.

    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.

    I'm actually going to start thinking of a way to incorporate a sodium fuel cell type tube like y'all made into my cars existing intercooler and cooling system. Then you could get rid of your alternator and possibly radiator or intercooler if it's efficient enough. That's an awesome idea and great food for thought!

  • @MauroTamm
    @MauroTamm 2 หลายเดือนก่อน +12

    Could also be geothermal - all you need is a high temperature for sodium.
    Bury the sodium PV cells in the mantle, instead of steam generators.
    But current ones slso need cooling and thermal management. No pv cell can just perfectly function at high temp long term.

      the point of using sodium is it emits light at only one wavelength. so having a special solar cell that is fine tuned to that specific wavelength increases efficiency. using another compound ruins that.

      The effieciency lies in matching the band gap of the photovoltaic cell
      to the narrow yellow emission band (spectral line) of the hot sodium.
      That is where Danielle Fong, et al., thought outside the box.

      Forget the candles. How much power is going through a car engine, jet aircraft engine, or large rocket engine like SpaceX Raptor? Raptor is around 8 gigawatts. If the energy conversion efficiency is the same 80% quoted earlier then that’s 6.4 gigawatts of electricity. California is using 19 gigawatts right as I type this, so about 3 Raptors worth of propellant burn is needed (about 310 pounds methane per second per Raptor, so around 900-1,000 pounds per second for all of California).

    it would be really interesting if you could do this with concentrated solar. have concentrated mirrors that burn a material to create a light at a wave length that you can capture more of with a cheaper material than pvs. thus, you up the efficiency and lower the costs.

      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

    @ericleonhardt4102 หลายเดือนก่อน +1

    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.

      @@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.

      @teardowndan5364 2 หลายเดือนก่อน +2

      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.

    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.
