Yes, I wonder how the limit changes as your light source changes, I'd suspect high energy blue light is easier to convert then reder light. Even sunlight at the Earths surface has been substantially altered from a true blackbody specturm due to absorbtion and reflection in the atmosphere, the visible part of the spectrum suffers the least loss and is the peak output and what our solar panels mostly harvest. So a true 6k black body spectrum such as in orbit is likely to be less efficient because the extra light your getting is in unusable parts of the spectrum, and thus your actual energy output remains the same even as the total input grows.

But, in terms of privacy, if you plan to sell excess energy back to some utility for those who do not invest in such tech, thereby breaking even on the longest term maintenance and replacement fees (sustainable), then having a neighborhood entity act on your behalf is an advantage. The utility could see Neighborhood 1's energy production for the grid, but not the individual members of the co-op/corporation. In this way, it is private how much energy each household uses, creates, or sells back to the grid. If run as a non-profit, this masking effect is absolute. If it returns profits to shareholders (the neighborhood's residents), they do so with their own payout structure, and until a transfer of money is required, it remains private (you could credit their account with kilowatt hours until they wished a full or partial withdraw of its agreed to value).

It also seems quite modular & relatively compact ; compared to say pumped hydro. All this whilst still offering long term season to season storage. Also on offer is the ability to reduce & significantly boosts its output power levels. Obviously a few testbed commercial plants need building, to assess its true usefulness. Seemingly we should be trying to establish as manyfold methods of energy storage & generation, as possible; before a good mix will emerge.

You could embed electric heating elements near the tin circulation piping to act as an in place restart system. It would also be useful for allowing you to take the system offline for maintenance without having to drain the system; i.e for replacing tpv elements or tungsten emitters.

50% efficiency is pretty good, about double that of a gasoline engine. So that raises an interesting question. Suppose you made a rectangular prism with dimensions around 60x45x45 cm with the four internal large faces covered in this thermophotovoltaic material and backed with a cooling system. That gives you about 1 square meter which should be good for around 100kW, according to the video. Down the center of the cavity you run a tungsten tube into which you inject burning fuel (gasoline, diesel, maybe hydrogen, etc.) to heat the tube to the target temperature (maybe pre-heating the fuel-air mix by using it in a secondary coolant loop). That would give you a lightweight, compact, clean, quiet, no-moving-parts gasoline-powered electric generator with output power about the same as the gasoline engine in a Toyota Prius, but with around double the efficiency (and probably even better emissions). Add a relatively small lithium battery to provide energy storage and a somewhat larger electric drive motor and you've got a hybrid that might approach 100 MPG with dramatically reduced mechanical complexity.

Too many technology combinations that try to cover all the bases is too expensive and there are no guarantees and so far, efficiency is pretty low, expensive and requires too many compromises that are not healthy for the earth or people.

It is less complicated related to legacy coal/steam power station. Probably cheaper too. But compared to a solar panel + battery combo? Something is off in their calculation. First, you get energy from some source that generates high temp, high enough to melt the metal. You already lost some of energy there. Then you transport the liquid metal through the carbon "battery". You lost some of energy again. Then when you actually want the electricity, you transfer the heat to tungsten plate (you lose some of energy there) which will transfer the energy to TPV cells, that are now at 41% efficiency and could be in theory up to a 50%. You are also cooling down those cells and heat is lost in the heating the water. How much of energy have been lost from the initial source (back where we were melting the metal) to the moment the electricity is flowing to a grid? It simply does not add up. Now, for sure, we HAVE to find a way to use all the heat that is wasted all around the industry. Multilayered cells seems like a great thing. And infra based cells are good.

*41% converted to electric power? NOT BLOODY LIKELY!* At 10:37 "tungsten filament at 2400 degrees C" (2673 K), that Tungsten (or any other blackbody emitter) will radiate over 2.8 _megawatts_ per square meter. With TPV output of 0.1 megawatts per square meter, the implied efficiency of TPV is a mere 3.5 percent! Plus it is extremely difficult to get concentrated sunlight to deliver such a high temperature, because whatever you use to absorb the light will re-radiate megawatts per square meter, and lose even more by convection of air on the exposed surface. All other heat sources are FAR cooler than what sunlight can theoretically deliver (5800 K), except for primary combustion. Sure, they might use this TPV thing to convert combustion heat, but at an utterly lousy 3.5% efficiency? No, no, no!!! And then that TPV requires aggressive cooling, which means a low temperature of the waste heat from cooling it. No way to regain efficiency there! The math for 2000 °C is even crazier. The video explanation given just totally fails to work.

And we scale the whole thing by just putting in a thousand of the cubes? Completely ignoring the cooling requirements explained a moment earlier. The whole thing sounds laughable.

MSRs are advanced (gen IV) nuclear reactors that promise greater fuel burnup and can run on Thorium or Uranium, and some are looking to consume Spent Nuclear Fuel. What is interesting as that MSRs can typically generate higher temperatures, about 1200F. If 50% efficient thermal to electrical conversion can be achieved at this temperature, this cell might be a better solution than a steam turbine or even a closed Brayton cycle power conversion system which is theoretically capable of 50% efficiency, but I don't believe any have been built at scale.

This is similar to a gas +PV attachment I had proposed and tinkered with in the 90's. I had found that a brand of highly efficient gas heaters burned a bright yellow that would charge a photocell from half to full capacity. The problem I ran into was soot (microparticles) in and leaking from the combustion chamber. It builds up too fast on the photocell and any glass divider in the chamber. I only got one week (8 days) of full capacity, and a sharp decline to 30%! Soot attracts soot. And yes, a filter for the intake was already part of the system.

Lots of places that could reduce system efficiency.

Both require millions of tons of material resources to produce. It takes about 1000kwh in manufacturing, maintenance and resources for each 1kwh a wind turbine or solar field produces. The environmental impact of a single wind turbine in a single year is equal to 100 1971 360ci Chrysler Newports driving 50 miles a day for 5 years.

A wave's kinetic energy can easily be converted into potential energy by raising a mass with each wave that passes. This potential energy can be converted into electricity by coupling the mass to a generator and lowering it when desired. If the distance to the customer is too large to transport electricity via power lines, converting the wave's kinetic energy to potential energy first is wasteful. It can still be used locally to desalinate seawater (to name but a hot topic) or generate hydrogen and then be shipped out. The advantages are that this can be scaled up more than most land based energy storage devices, the price of ocean being low compared to the price of land and the many more regulations a land based design must adhere to. The disadvantage is distance to customer. Fortunately, most of us live near the coast.
