At last... Intelligent life in Space. 👍 A video for intelligent people.. Not in any way dumbing down for a supposed "Knuckle dragging" audience. Terran Space Academy should have at least a million subscribers by now. A massive Thumbs up for quality of content and I hope to see more soon.👍
What an absolute beauty of a video! Highly informative and straight to the point. Subscribed and I'll be watching every single video on the channel, as well as future uploads. Fantastic work!!!
12:55 - I think it's exactly the opposite. Entropy must be increasing*, and a system must become more chaotic. Increased entropy means increased chaos. Order is lost over time. Entropy is an expression of the disorder, or randomness of a system, or of the lack of information about it. It's (kind of) the combinatorial number of possible unobservable states, that would sum up to produce the observed. (* or stay the same)
Entropy must increase for the universe overall but local conditions can decrease in entropy. The sun's breakdown fuels the decreased entropy mechanisms we call life :-)
@@terranspaceacademy wrong timestamp (now fixed), but my comment stays. You are defining entropy incorrectly: you are stating the opposite. You said: "Entropy is a measure of the order of a system. Random has low. Ordered has high."
15:20 when you have an engine or a gas turbine you can use the heat for different purposes like heating houses or facilities or if it is hot enough to run a Steam turbine cycle
Stirling engines have been around since 1800s so it's says something about our education system when comments say "I never heard of of a Stirling engine." Problem is that they produces very little torque/ horsepower, a 4 cylinder clunking build puts out .5 horsepower. Wow. It's an interesting concept serving to inspire better ones.
@@CUBETechieOh, I thought you were talking about a different lesson. Boron works well for fusion reactions but I’m not familiar with its use for fission.
Where in the video? Thermal management is critical to any electromagnetic device. The Stirling heat pump can get temperatures down to 20K. With heat pipes it should be easy to cool them as long as there is power.
@@terranspaceacademy in 28:28 and 19:16 sterling engine pistol movement is used to create electricity by linear generator. The magnets are attached to the pistol and surrounded by coils. The heat could transfer from pistol to the magnets. I heat pipe can't control heat in the piston. Heat pipe is used just to maintain temperature in the cold side of sterling engine.
@@GiriPrasath001 These are commercial systems so the magnet must be able to tolerate the temperature is generated but I’ll check with that company. Thank you.
In regards to the Sterling heat/ cold conversion transference of power, could the temperatures of space generate enough combustion to traverse through space, if we’re only utilizing fossil fuels, to enter and exit the atmosphere? And would a much larger heat pump generate enough energy from the Earths temperature to effectively generate enough energy to sustain a Dyson sphere?
We could use a nuclear pellet/block to generate heat... Pollonium maybe. And use Stirling engines to produce power from the heat flow to radiators... Remember there needs to be a differential for flux to occur.
I cannot just attach a wire to it, and let it fall... I would have to slow it down first... but wouldn't that kind of 'give it' it's potential energy? - The gravitational potential energy that I can get out of it, relative to what it is orbiting, should be zero if it is in orbit... as I cannot take any out of it... (by just moving it up a little from a local well) - this is just a feeling, though...
Everything that orbits has potential energy equal to mgh (massxgravityxheight). Gravity for Earth is 9.71m/s^2, for the Moon 1.33m/s^2. The object also has kinetic energy related to its lateral motion. The kinetic energy keeping it in orbit must be overcome to bring it down. On Earth if you get below about 150km the atmospheric drag will quickly help but on the Moon you could technically "orbit" 10m above the tallest surface feature in your orbital path...though you would be going really fast.
some late info. apparently, the first half of this video 'just needed a home, somewhere'. one joule equals one watt-second. at 20:17, any heat engine design, in which a flywheel/crankshaft assembly is not utilized, is an Inferior one. it can be Seen that any linear/Reciprocating alternator has the Exact same problem; NO conservation of momentum.! Spare me any blather about 'em. googletranslate
We have a word for a lunar day+night cycle, actually. It's "month" in English. Not particularly well defined because of the calendar system. I think we can call it "lunar month", and confuse the hell out of everybody.
Why not build power plants with large sterling engines? Using natural gas or even concentrated solar , with sand batteries, use a cooling pond, or tower, possibly a well, ( a underground pond or river) using a heat exchanger, to maintain the cool required, would it be more efficient than the steam turbines currently used,,? I know concentrated solar will be better for the earth, replacing just one or two coal plants would be worth it, the sand batteries can keep the engine going over night, generating power, usingt
Don't know why you need nuclear reactors in space when in space in the shade its 200 below and in the sun its 370 above. Seems like thats a good enough split. Unless you want to build some kind of rocket motor.
Excelente video!!! Gostaria de compartilharmos , 😃😃😃!!! Seja bemvindo ao meu canal!!! Juntos podemos ser mais fortes, desde já meus sinceros agradecimentos! Marcos Valério Ciência, Rio de Janeiro, Brasil!! Grande abraço!!!! Eu amo os motores stirlings!!!
Thank you for not dumbing things down

Thank you so much! We really appreciate you.
I've just re-watched this it's still great. Thanks.
Glad you enjoyed it! The sound is better now but some of the old ones had a lot of good data :-)

Martin Verrisin am I saying it backwards?
@@terranspaceacademy I think so. The timestamp is corrected, so feel free to check for yourself.
@@NwoDispatcher Energy cannot be created or destroyed.

Very true...
liked this one too ... thanks again !!!!

Very true. It will be used on the new Kilopower RTG system that NASA plans to use on Mars...
24:32 wouldn't it be better if the boron carbide goes up to starting the fission reaction ? And when something happen ☺️😯 Klick and it falls inside.
Boron can work for fusion but we aren't there yet...
@@terranspaceacademy maybe I misunderstood I mean the controll rod

Excellent video, info & content. Sub’d & like. TFS.
Thanks and welcome aboard!
Is the heat produced in the combustion would reach the permanent magnet and demagnetised?

@@terranspaceacademy if u got any updates please share with me. Thank u
Wow. I never knew about Stirling engines. Most informative. Thanks again as usual.
Very welcome Same!
I have a question
In regards to the Sterling heat/ cold conversion transference of power, could the temperatures of space generate enough combustion to traverse through space, if we’re only utilizing fossil fuels, to enter and exit the atmosphere? And would a much larger heat pump generate enough energy from the Earths temperature to effectively generate enough energy to sustain a Dyson sphere?
Utilizing space to house humanity and rebuild earth as a garden, such as it should’ve always been.
We could use a nuclear pellet/block to generate heat... Pollonium maybe. And use Stirling engines to produce power from the heat flow to radiators... Remember there needs to be a differential for flux to occur.
I need to absorb this, thoroughly. Thanks 🖖🏼
You're so welcome!
What medium did Stirling engines use? Is nitrogen Gas maybe the best medium because when it get hotter it expand 600 times
Probably helium since it will get the most kinetic energy out of a specific temperature but I'll have to look that up...
good work bro
Thank you so much.
So you need 10t and can power your suit for over 3h?
Keeps you alive :-)
Very very nice!!!!!!😊😊😊😊😊Bealtiful engenharia!!!
Thank you very much!
would something in orbit have potential energy? (i.e. similar to something 'held' to prevent it from falling)
I cannot just attach a wire to it, and let it fall... I would have to slow it down first... but wouldn't that kind of 'give it' it's potential energy?
- The gravitational potential energy that I can get out of it, relative to what it is orbiting, should be zero if it is in orbit... as I cannot take any out of it... (by just moving it up a little from a local well)

From Scotland and ignored since 1816 via Sweden . What took so long????
Sometimes the other designs have more support... look at Tesla fighting for AC :-)
So that's why there will never be a "perpetual motion" machine?
Not until we can tap "zero point energy" :-)

They have been considered but I think the new thermovoltaics will make almost everything else obsolete.
Wow, I hope Elon"s people are considering this!
I'm sure they are on it!

Muito obrigado e tenha um
What the hell does E=MC^2 have to do with a sterling engine?This thing is just a commercial.
Where? It’s been a while...
honestly, mars night, mars day, lunar night, lunar day... earth night, earth day... those are not that bad to use...
They use Sol for Mars, can't I get a Darklune? It sounds so cool...
@@terranspaceacademy I have nothing against it. I'm just saying using day/night + 'adjective' works well enough...
This video is scary
Which part? :-) And wait until you see the one on the Satan missile!
please skip the math
Can't :-( If we don't do the math we can't make our own designs...
