Hey thanks for the question! ❤️🔥🙏 Yup yup! You got it! Same Brayton Thermodynamic cycle as a regular gas turbine but with a supercritical fluid the density is SOOO much higher than with it in its lower pressure gas phase. But the fluid supercritical fluid still expands like a gas. So extremely high mass flow rates due to high density, so with high mass flow rates of a very hot high pressure elastic fluid, then there’s a high power output available. Which lends itself to having the entire system be 1/10th of a typical Rankine cycle system.
Check out the video I made about using Tesla turbines as steal trolling motors on nuclear submarines. I go a little further into supercritical fluids. Because a lot of reactors have supercritical steam as their reactor coolant system.

Supercritical CO2 critical temp 304.1K critical pressure 7.38MPa, density 467 kg/m3. 31c Supercritical SF6 critical temp 318.6K critical pressure 3.76MPa, density 736 kg/m3. 45.5c I know you would not want to release SF6 into air. SF6 is known for its high global warming potential (GWP) Xenon is more expensive but might be a good choice when a smaller footprint is needed. If you could increase efficiency or expand operating range maybe it would be worth exploring as well.
I was JUST thinking about this when I first came across your videos because I follow Flibe energy who is doing research specifically on multen salt reactors. They have been set on CO2 turbine systems for a few years now, so I'm really excited to see this.
Thank you so much for doing this! Love your "Tesla look" with the mustache and a good looking vest as well haha. You said that we could ask you any question in another comment. May I please ask you if you are ever going to sell a book, on the exact mathematics of different sizes and amount of blades for Tesla turbines and details of other systems, so communities around the world who are capable, could build it themselves? For example when your business goes well and you won't need this "small scale" stuff anymore?
I read a few years ago and that siemens had a prototype turbine running on superctrical co2 and the results showed that at start temperatures above 800°C the efficiency is quite a bit higher than with steam
I read an article titled "Preliminary Design and Off-Design Analysis of a Radial Outflow Turbine for Organic Rankine Cycles" by Jun-Seong Kim and Do-Yeop Kim, published in April 2020. The article claimed that a 400 kW Radial Outflow Turbine generator for sCO₂ could operate at 85% efficiency. For reference, 400 kW is equivalent to 536 horsepower. For an EV hybrid this system could potentially offer a much lower weight burden compared to relying entirely on batteries, while at the same time dramatically increasing range.
Was the performance data from the 10 megawatt pilot project ever published? I wanted the initial CO2 conditions, the temperature at the gas cooler, and an efficiency figure. I think it was only ever loaded at 1 megawatt accodding to one other video I saw.
Fact is when steam is heated to very high temperature after a while the steam become gaslike and if Co2 is infused into the water before heating tye temperature will real extraordinary temperature fast and more powerful to rotate engine or turbine.
Nice!! How much of a power generation increase are we looking at with CO2 vs cold steam under vacuum? Will the turbine need to be redesigned to work with SC-CO2? I'm guessing disc spacing might need to change to account for the increased viscosity of the working fluid. Keep up the great work Charlie!
Hey thanks for commenting! It itself is not renewable as any heat source can be used to power it. However, because the thermodynamic cycle efficiency of supercritical fluids is that much higher than conventional steam systems, using it with our same current fuels would make a significant reduction in the greenhouse gasses produced to output the same amount of electricity. So while is not a full proof solution, it’s certainly a step in the right direction and any R&D development in it will equally benefit any and all renewable energy sources like solar thermal and biomass are used instead of fossil fuels. Hope that helps!
I don't get it. where goes the liquified CO2? In the atmosphere? And second - you need energy to make that pressure and temperature, no? They said efficiency. This means that they are still struggling to make more output then input. And they are already wondering who is gonna use it and how the things will balance?
Hey thanks for commenting. ❤️🔥🙏 It’s a closed loop system. the supercritical co2 (not liquid) just continuously loops in a cycles. And yes it still requires heat input but because the thermodynamic efficiency is so much higher even just switching our current fossil fuel steam turbine system to this would see a significant reduction in greenhouse gasses alone. Not to mention this can be used with nuclear, solar thermal, biomass, anything and it will yield more electricity per input energy. Which means the hot snd cold side heat exchangers can be much smaller because not as much heat has to still be removed because more goes to electricity. It would still be more efficient than using those same heat sources with the current steam that we do. To be clear though, no turbine or engine can output more than what is input. That would break the laws of physics. Fortunately With TesTur Energy, we’re committed to empowering individuals with energy autonomy through our Combined Heat And Power (CHP) solutions. Our systems are uniquely designed to harness overlooked energy resources like biomass, solar thermal, and geothermal, as well as unconventional fuels rich in solid particulates-think sawdust, pulverized coal, or powdered iron. Traditionally, these alternative energy sources and fuels have been underexploited due to the limitations of existing turbines and engines. These systems often can’t manage the complex fluid flows-mixtures of gases, liquids, and solid particles-that are characteristic of low-grade heat boilers and unconventional fuels. But our technology changes that, enabling sustained, damage-free operation even in these challenging conditions. www.HeatAndPower.com www.TesTurEnergy.com
Hey thanks for commenting ❤️🔥🙏 This works for nuclear fuel sources too. It’s a turbine and motive fluid system with heat exchangers. Where the heat comes from is really dealers choice. Let me know if you have any questions! Cheers mate
So if I understand this correctly, the supercritical CO2 would replace steam as the driving fluid for power generating turbines?

But the "exhaust gas" can be used for heating or hot water to the hot water pipes

Hey thank for the comment! ❤️🔥🙏
Do you happen to remember where they did those tests at?
Cheers!
@@CharlieSolis a quick search made me find something about the carbosola project. But I'm not sure sure it was that what I read
@@GeoffHou I’ll take a look! Thanks for sharing!

Where can I learn more/see this equipment in action. I really like this project and see potential.
Basically, what I want to see is a process and instrumentation diagram.
How long until you can strap one of your turbines to an off-the-shelf CO2 oil extraction setup?
Fact is when steam is heated to very high temperature after a while the steam become gaslike and if Co2 is infused into the water before heating tye temperature will real extraordinary temperature fast and more powerful to rotate engine or turbine.
What is the energy source? What heats and pressurizes the CO2?
dont ask awkward questions. just get down on your knees, and give much adulation.
Literally anything. Just like all other turbine generators.

Is supercritical co2 in itself renewable???

Doubt that scco2 looks like honey
Why would it?
