I got hands on with this tech video in the link kzfaq.info/get/bejne/Z9CdfrNjrsqsXXU.html Hands On Supercritical CO2 Turbine Explained {Future Friday Ep204}

Every second of this video is a high density information delivery. One of the best explanation videos i'have seen about the subject. I wish all my college courses were this format. Great job !

You are a master of presenting a ton of information in a short amount of time in a fun and concise way. I really enjoyed this.

Dude, that talk was packed chock-a-block with information. It was a fast delivery but you saved me time. Typically, I would have needed a couple of hours to comprehend the same by reading. Are you a teacher/lecturer/professor ? The video also had its funny moments with expression like "hot puppy" and " 24 hour amazon delivery". Keep up the good work and your talent!

This is the future of power generation. I would like to know more aout the corrosive effect of co2 on metal. If it is a hermetically sealed system, then moisture, which when misxed with co2 produces carbonic acid, should not be a factor. Also if this was combined with a graphine heat extraction method, instead of EGS, then a geothermal plant could be located anywhere in the world with no imputes and no pollution. This presentation is the most well thought out and lucid I have seen yet. Good Job.

"This... the big, giant-ass turbine..." I'm cracking up!

Thank you for this quality. I learned a lot. You do us a great favor by keep doing this great work. Is much appreciated!

Excellent, condensed, straight to the point explanation. Thank you!

I can just see how underrated some channels are... Great explanation sir🙏 I wish u more subscribers

Very interesting and easy to understand! Didn't notice how 15 minutes passed. Thank you!

Awesome presentation! Keep up the good work! Subscribed and Liked

True, most of the power is generated with a low efficiency, but with combined cycle new machinery they are able to generate above 60% with the record being nearly 64%.

This puppy explained the entire game very well .

I appreciate the energy of the speaker

Nice and very informative summary. If you want to improve your videos comprehensability, please talk at 0,8 times your speed and please remove the background music that sometimes blends with your voice. If that is an option use a clip on microphone for recording.

Again with the semi truck example. SF6 must be subjected to conditions above its critical temperature and critical pressure. The critical temperature for SF6 is approximately 45.55°C (114°F), and the critical pressure is about 3.78 MPa (37.8 bar or 548 psi). In the supercritical phase, SF6 exhibits properties of both gases and liquids. CO2 density at 31c and 74 bar 0.468g/cm3, H2o at 374c and 221 bar 0.322 g/cm3, SF6 44.55c and 37.8bar 0.74 g/cm3.

3:19 That's Ben Krasnow's homemade 2000PSI pressure cell from Applied Science. Thank god it did not explode during testing. One "sealing technology" challenge here is how to have an axle that does not allow the CO2 to leak but without gaskets that would cause so much friction. Magnetic gears are possible but the vessel walls are too thick. Contain the entire setup in supercritical CO2? Maybe

at 8:26 - Is it 5-10% more efficient or 5-10 times more efficient? The audio doesn't match the PPT screen.

Great explanation, thank you for sharing!

Without a doubts on the theoretical level sCO2 is a great technology. However, the presentation should not start with inaccurate statements: Modern (Supercritical) Rankine steam cycle delivers 40% thermal efficiency and more. (i.e. not 33% as claimed in presentation). Further more the presentation talks about early stages of sCO2 cycle development: supercritical discharge from turbine. As in Rankine cycle sCO2 today is designed to have turbine discharge pressure well below supercritical CO2 (e.g., ~400 psia vs critical P=1070 psia) with the only purpose to increase the efficiency. Note the Low-Pressure steam turbine delivers almost 50% of electrical output of a modern steam power plant. While I am still in favor of sCO2 cycle the main question remains: where would the CO2 in supercritical state would come from to compensate such cycle working fluid losses. Keep in mind that working fluid for steam cycle requires only chemical treatment. Getting supercritical CO2 is a high energy consumption process. I wounder what is the impact on overall system efficiency assuming 2% CO2 leakage in the system. (Note, a regular air compression system is usually designed for 15% leakage).

Excellent!

Is brayton cycle means working fluid in same state , here in supercritical state?

Could it be potentially feasible to use the Brayton or Rankine Cycle to produce electricity for semi trucks thus reducing the parasitic loads from alternator, pumps etc. It takes for example (40% efficiency) 93kw of power to drive down road at 62mph but a total power output of 232.5kw of power must be generated. This leaves 139.5kw of power that does not go directly to moving truck. There are about 10kw of power that go to run things like alternator (estimate using duty cycle), pumps etc. If you could get decent efficiency with the Brayton cycle maybe you could generate the 19kw of power need for a dual zone reefer trailer.

great video, well presented

Wow, that was a brilliant presentation, I came here to find out how to make CO2 for a CO2 battery like what energy dome have done and it's interesting to find out it can also be used for generation, this definition looks like the most promising technology for generation and storage that I have seen so far 👍👍

Thanks for your presentation. I learned a few things and it sparked more interest. All success to you.

Thanks a lot for the video! I had to slow you down to 0.75:- )

Awesome Video!! ..one of the best explanations I have seen!

Great video. thank you!

Sharp, Accurate, to the point, Loved It

NICE EXPLANATION THANKS

OK so I had to slow you down to .75 to actually catch all of what you were saying, but otherwise an excellent presentation!

Good presentation, could try and talk a little slower (with poise). For most people, English is not their first language.

Wonderful video. It gave a brief insight about SCO2 turbines.

Amazing video, keep them coming! :)

Love the video. It sucks the first hit above your video is AI garbage, your's delivered everything I was looking for. On the topic of inertia, I understand steam turbines are pretty beefy, but could the generator with a flywheel take up the inertia from the grid?

Awesome, thank you sir! Not going to lie i had to slow it down but am an uneducated Aussie an takes a while for things to sink in, but loved ya presentation cheers!

Great explainer video. Which companies are leading the development of these turbines?

That was an amazing video, congratulations!

So how does it work!?

Excellent video, I only have one criticism. You talked so fast in it, it was like you were on Adderall. I had to slow it down to be able to understand you.

Awesome presentation.

Sir I need this topic ppt presentation

No way that thing can churn through 10mw. The material strain would tear it apart. It's too small.

I would love to see an update on this tech, how much progress?

Great explanation - thank you.

Thank you for the interesting knowledge.

Thank you!

Thank you sir.

Thank u this is Great info

Excellen explanation! However, please dont speak so fast, due to your accent, it is not possible to understand 100% the presentation.

Game changer.

very informative, but try to talk a bit slower :-)

Please explain slowly

Dude can you talk slower...or just slo-mo your video if you cant...you have to cut down on sugar or caffeine...

Could you please speak slowly. It is very hard to understand you. Thanks

you have to really work on your pronunciation

nice presentation.

Great video, but need to slow down talking a bit. Hard to follow
