bro ate. This was very informative and entertaining to watch. Subscribed! Quick Question, I am undergoing a research on a parabolic dish system optimization, and I am thinking if I can increase the efficiency of the device if the power conversion unit is a stirling engine coupled with an ORC for waste heat utilization. What do you think of this idea?
issue is always the same if you put LOAD on the waste heat stream you reduce the effecicy of the main system and the add one rerely add enough to justify it so from cost and simplicity and maintenance point of view its prefered to just have on stage or some passive use of waste heat
I stumbled upon your insightful video and I appreciate the depth of your analysis. Would you be open to further discussion on this topic? I'd love to hear more of your insights or any additional resources you might recommend.
Theory: Hot side: solar thermal Cold Side: geo Working fluid: propane Application: simple loop utilizing natural convection. Priming pump, priming pump bypass, regulator valve, tesla valve and tesla turbine. Overflow canister used on high pressure side as a buffer for pressure fluctuations. Concerns: velocity of working fluid, freezing at heat source or flash point at condensor.
@@s2tenglish I was bored and started scribbling only to find out I'd come up with simplified ORC generator. :D Solar thermal panels are around 3x more efficient than your photovoltaic panels. Could work for a small system or even a small household system. You're much smarter than I am. Could this concept be viable?
Isn't it basically (Th-Tc)/Th gives you the theoretical limit of efficiency? As, 400 K hot side - 300 K cold side could produce 25% efficiency, if you had a perfect heat engine, and absolutely no losses. The other big issue is that refers to actual temperatures of the working fluid, not the temperature of the actual heat source, or temperature of what you reject the heat to. And the lower the temperature difference, the less heat transfer you get in a given heat exchanger.
Loved the explanation! Well done!
Glad you liked it
I like your explanation. I liked and subscribed!
Awesome, glad you liekd it
Is there a formula to measure Kw, or turbine sizing with the temperature delta or the thermal efficiency?
get a quote from the company making it . they will give you a graph of there tool and its output based on different temperature delta
love the way you explain
Thanks
What would we get with cascading two or more ORC?
nothing as radiator will struggle to dump heat into the next stage

Thanks & the 5 videos I have linkedin the description should provide some more data
Can we employ this rankine cycle in air compressors heat rejection and generate power from it ?
very little power would be made that way
If I have a turbine generator, Is there an approximation or empiric value to calculate the amount of energy can be produced with a rankine system?
there must be some online calculator
Well explained
Thanks

Okay

it does not work on small scale that is why we use PV pannel

On paper yes but that is not real life .
are there small scale ORC gadget for domestic usage yet?
nope its too expencive for too little power
does it use a compressor ?
in some design yes
Do you think population collapse will be recovered
Not likely
