Red colour has the least dispersion. Every warning signals use red for a reason. An Illuminated Name Board with red as the light colour will have a readability of upto 2-3 Kilometres while that uses green or blue has less than a kilometre. Both sunrise and sunset have a red sky for a reason. Red colour simply travel more with less dispersion. Same reason why in a foggy day if you have a halogen bulb as your vehicle headlight you will have more visibility when compared with white LED, because warm light has more red in it.

Interesting, I never had a problem reading displays without filter. The inactive segments don't bother me at all. And before you mentioned it, I didn't even noticed that some products have the filter and others don't. But I guess in specific lighting conditions the display with filter would be easier to read.

I also have to say that the longer wavelength an LED display uses, the better I can read it from afar. A blue LED seen across the room makes a much "less focused" image in my vision than a red one (violet is even worse, green is in between, etc). I'm 18yo and I can see extremely well at any distance, so I guess it should be a common human thing (at least with the common circumstances we live under)
My ranting spills over into another comment, but despite what a lot of people think, often the case is the same lazy hiring practices lead to lack of diversity AND to a team that is less competent! Usually this means hiring based on vague feelings of comfort with people, or hiring your friends. Sure, you can think of 5 people you worked with before who are probably good enough, but are they actually the best 5 people to hire? Hiring based on useful, objective criteria you can evaluate both tends to lead to more diversity and also better employees. But it also requires effort :)
Because of the discharge curve of a capacitor I think it would be useful to have a step up converter to suck more energy from the bottom of the caps. Perhaps common 3.3V would make more sense?

If I remember correctly, amorphous solar panels are the least efficient but they have a low directivity and a low leakage current, which means they work better indoors, at low light levels. They are used in solar powered calculators and have a brown color. Polycrystalline and monocrystalline solar panels are the most efficient but they have a higher directivity, and a higher leakage current, so they are better suited to outdoors applications with direct sunlight illumination. Polycrystalline solar panels are blue with galvanized steel patterns, while the monocrystalline ones are plain blue.
I've always thought these cheap solar cells can't possibly be very good, and I think you've proved it there with the differences between the two halves of the same panel. The problem is that you can't really get anything in between these and the big panels that go on your roof, which definitely isn't practical for such a small application.
What about the panels for charging your car's battery that you put on the dashboard or fix in a window. They're usually 300mm plus in length for good ones.
To be honest, I also hate people going with what's fashionable. To use an example that is not so politically charged--Arduino and Raspberry Pi. Sure they are fine, and you can make a lot of things work with them, but any time I see someone use them it makes me wince a little bit because it's rarely the *best* choice. Arduino is designed for educational purposes, and Raspberry Pi is designed to be as cheap as possible. You can build your own microcontroller circuit for 1/3 the cost of an Arduino, and for a single-board computer you can get something much much more powerful than a Raspberry Pi for not that much more money. Especially when you see someone build things that use like 12 Pis, when you could replace that with a single SBC that's a bit more capable probably for lower total cost. Or as is often the case you could replace it with an ESP32 when all you need is something internet-connected that can toggle a GPIO. But ESP32 is also trendy these days :)
Believe it or not, in some countries with a lot of restrictions and taxes on imports it is actually cheaper to buy an Arduino(clone) board than to actually buy the individual components. And there is a lot less variety of specialized ICs.
I guess at such a low power level it's too lossy and overcomplicated for the purpose. It actually might bee good for the display current to decline as the capacitor discharges. This prevents it from suddenly shutting down at undervoltage. The way it is, the current generation and draw can self-ballance.
Yeah.. Nowadays, people only care about comfort and looks. Most people I know my age wouldn't know how to communicate with someone far away without internet or phone service, or start a car if the battery runs out, or what to do when there is a power outage besides waiting, or anything whatsoever extra than what they do daily or weekly, and they just don't seem to care at all. But any and every single one of them can create an Instagram account in the blink of an eye. And let alone having a conversation where I can expose my opinions in a respectful and organized manner and get an answer in the same format, without insults and disrespect and gaslighting mixed in every sentence. They don't know how to communicate, how to operate or how to live in a normal society. Things won't last long like this
They used to put color filters directly on the LED displays. Now they use just clear removable protective film. Non removable color film would make more sense.
That comparison of the two sides of the solar panel is excellent, QA or QC issue. Love your comment on the dims that believe in solar highways (etc). Ok this video is a rant on stupidy (-: sweet. A while ago i head a person could get grants if it backed climate change, but otherwise a lot hader to get a grant (we don't need people to figure out solutions, prove the problem might exist). People that have an active brain need to realize all governments are reactive not proactive and proactive people tend to avoid the accident, the others blame the wall for being in the way, crunch.
I'm not sure, but I think the human eye is a bit hyperopic for red light and myopic for blue light. Because of this, you can read the red indicator from a greater distance.
I've always thought that super caps are generally no good except for a very small number of special applications. Would be good to see a comparison of super caps vs NiMH/ Lithium Ion.
The clouds scatter the light from the sun onto the panel, open sky doesnt scatter anything is why clouds can give more energy, open sky (blue) doesnt reflect anything, its basically a reflection itself. Off Grid Garage's channel experieces this phenonemon with his solar setup, getting more on cloudy days because his panels arent in the sun, they're covered by shade from trees. But on a cloudy day these panels produce more then on a sunny day because they're getting ambient lights scatter from the clouds.
great video as always, even better when you start talking about things that the world must know but no one wants to talk about because it's unpopular opinion
In a low voltage solar system, there will be significant power losses in the zener diode. Would it make sense to use a logic level mosfet to prevent discharging the battery when there is no solar output?
Dany its a pity u cant tolerate longer videos. I feel like they always end just when yr getting up to full steam. Lol at team size and eating pets 😂 v v funny. Anyway instead of cleaning our filthy windows on my day off, im going to the "office" to open up our fairy lights little solar unit which ive had saved for awhile - under the supervision of our cats of course. Ty as always for another great video
Instead of dark filter use a piece of electrical tape the same color as the display. It doesn't attenuate the light that much and still makes the display much more readable in bright conditions.
I don't think it's just your eyes. For many years now, I've noticed that I have a lot more trouble focusing on blue lights at a distance in the dark than I do red lights. Green lights are somewhere in between. I suspect the optics of the human eye have more difficulty focusing on shorter wavelengths.
It really is a bummer about how fast the super caps self discharge. Does seem to limit their usefulness in so many applications. I picked up a 5 pack of some nice, 250x250mm glass solar panels a few years ago, but haven’t figured out what I want to use them for 🤔. Maybe a few garden lights.
Yeah @@BRUXXUS I think the supercap needs to CV soak for several hours to accumulate all the charges in every nook and cranny, then self discharge will be quite low. I'm using my small solar cells to keep small batteries charged so I stop purchasing battery replacements. Thin film and amorphous is the best for low light...
I have a word about that vision thing. I can blur my vision whenever i want and when I'm watching youtube for example, when nothing interesting happens on screen I'm blurring my vision :D
@@maheen- i know that it is nothing amusing but because of that my eyes aren't constantly focusing on close distance and I don't have problems with them. Every optic told me that I have very good vision and I am spending a lot of time in front of the displays
You could use a charge pump regulator to double 1.5v+ with high efficiency, 90%+ ... and you keep complaining about voltage with the seven segment displays but it's all about the resistance you use to limit current going to segments. There are seven segment led drivers you can use to set maximum current per segment and which allow you to adjust brightness by pwm-ing the led segments. So you could have high brightness during the day and less during the night when running on supercapacitor or battery.
Never understand trying to use suppercaps as batteries! Batteries make much better suppercaps 🙂 if i want a battery that can provide sudden high current bursts then a battery with some supercaps in parallel would be great.
I suppose you could get carried away, create an array of 100 super caps individually connected to a custom BMS which is charged from solar panels then with the caps connected in series to a buck converter power whatever the cat will permit. Nice.
I just don't see the application of Super Caps being much use in these low voltage applications. Using ANY lithium cells seems to just be the way to go. And you can even use your old OLD Tired Cell phone batteries that do still produce voltage but hardly any current anymore. That's what I have been doing with my old Laptop Cells. They work PERFECT for these very low draw applications with a solar cell. So if you have outdoor Candle flicker type lights like I do? They work PERFECTLY to keep the Batteries topped off at 4.2v or so. I'm going to experiment and see if I can just run them with nothing but A Diode and a solar cells. I have not got around to it since the 18650's I use do such a nice job as is. And last about 2 weeks before I have to recharge them.
Není lepší za cenu těch komponentů udělat obvod na 9V baterie? Kdyz se použijou dvě paralelně tak to vydrží podle mě hodně dlouho. A cena jedné 9V baterie je kolem 40kč. Ty solární panely museli stát víc než 300kč spolu a nepočítam superkapacitory. Doma mám jedny hodiny co ukazují všechno ( roky, dny, hodiny, minuty , vteřiny, datum i s kalendárním týdnem pak teplotu venku kde je samostatně senzor napájený 2xAA, tlak, vlhkost, teplotu uvnitř, vlhkost uvnitř ) a má ze zadu i takovej jakoby 3,5mm jack na sluchátka ale je to k napájení přes solarni panel a rozsah je tam od 4,5 do 10V. Do samotnych hodin jdou 3xAA baterie a kdyz se tam dají nabíjetelné, v menu hodin stačí zmáčknout že se používají dobíjetelné a uz samotne hodiny dokážou regulovat i nabíjení skrze ten solární panel.

@@DiodeGoneWildwell the unfortunate thing is that social media is not conducive to turning these conversations productive. You can see that the majority of comments here are saying they agree with you. Is that because most of your viewers already agree with you, or because people who disagree did not comment? Personally it made me a little hesitant to engage because I suspect people will just dogpile me if I disagree with you--as often happens. For one example where this happened was Dr. John Campbell's channel during COVID. He made some expressions of personal disagreement with some things respecting how Ivermectin was being considered. His opinions themselves were totally reasonable, but they rapidly led to his comment section becoming flooded with anti-vax conspiracy theorists praising him, and people outside those groups stopped watching his videos as much. The hazard with expressing these opinions is not so much that it will hurt you in some way--in fact it could even lead to more success for your channel. The hazard is that it may narrow your audience to just the people who agree. It doesn't really bother me that you said what you said in this video, even though I may disagree with it. But it does bother me how half the comments on this video are people praising you for that commentary instead of talking about the core content of the video. I don't like to spend time on channels that become nasty cheerleading teams like this.
@@rfmerrill It's because in Eastern Europe you can actually say this freely and everyone would agree. It's considered normal to say this, not like in the West.
the discharge curve of a cap (12:50) is a straight line, just in case when you're discharging with constant current ..wrong / totally wrong / or something else? .)
That’s a good old whinge about the state if the world. I do agree. As for the project doesn’t it just prove you cannot have a solar powered design that works in various conditions and isn’t over-engineered so it’s better to use the mains and have some proper grid-tied solar panels on your roof.

well if you use the suns energy more you wouldnt be spending trillions on fighting for oil and territory and would have more money for food maybe? its more then fashionable i think its called energy independance. Maybe spend that money on exploring the universe. Imagine if we could use more the 20% efficiencey. That with superconductors would bring peace on earth. Everyones just fighting for energy... and theres tonnes of it free in space.
Sun energy definitely isn't bad. It surely helps a lot. I just mean that it can't solve everything. Especially the storage on a grid level scale is just a concept.
Over half of California's electricity is supplied by wind and solar during the daytime, so it makes a huge difference! But as Danyk points out, we still have not solved the problem of storing it, so our net demand still has a big spike around sunset--when everyone is getting home from work, aircon is running because it's still hot, but solar is falling off. as I type this right now, CAISO reports total demand at 25,244 megawatts, and of that 12,582 megawatts are supplied by solar! The graphs show that there are some large battery banks that supply 3000 Megawatt at peak during that sunset demand, but the gap still has to be made up by natural gas.
Renewable energies will be good for the planet if correctly done but will never be free for citizens. Nobody fights for energy, they fight for money, solar energy isn't free, the panels, inverters, batteries, wires, etc. don't grow on trees, haven't you noticed that the oil companies themselves are becoming the owners of most of the renewable energy industry? They are trying to buy all those companies like they're trying to buy all the lithium mines and so on, we will continue to depend on the same companies that control the oil market even if the cars use batteries, fuel cells or any other alternative power source.

Or as is often the case you could replace it with an ESP32 when all you need is something internet-connected that can toggle a GPIO. But ESP32 is also trendy these days :)
Yes, Arduino and Raspberry Pi are the pleague of today's "DIY" ...
What MCU or asic would you recommend for a DIY PLC application?
Believe it or not, in some countries with a lot of restrictions and taxes on imports it is actually cheaper to buy an Arduino(clone) board than to actually buy the individual components. And there is a lot less variety of specialized ICs.
You could use some sort of voltage regulator to keep the discharging curve more constant. Maybe something like a joule thief would work?
I guess at such a low power level it's too lossy and overcomplicated for the purpose. It actually might bee good for the display current to decline as the capacitor discharges. This prevents it from suddenly shutting down at undervoltage. The way it is, the current generation and draw can self-ballance.
Great video! I really appreciate your comments on what's fashionable. Now I know and can join the club! ;-)
Thank you for doing your part and preventing the world from ending in .. uhh.. 12 years.
Yeah.. Nowadays, people only care about comfort and looks. Most people I know my age wouldn't know how to communicate with someone far away without internet or phone service, or start a car if the battery runs out, or what to do when there is a power outage besides waiting, or anything whatsoever extra than what they do daily or weekly, and they just don't seem to care at all. But any and every single one of them can create an Instagram account in the blink of an eye. And let alone having a conversation where I can expose my opinions in a respectful and organized manner and get an answer in the same format, without insults and disrespect and gaslighting mixed in every sentence. They don't know how to communicate, how to operate or how to live in a normal society. Things won't last long like this
They used to put color filters directly on the LED displays. Now they use just clear removable protective film. Non removable color film would make more sense.
That comparison of the two sides of the solar panel is excellent, QA or QC issue. Love your comment on the dims that believe in solar highways (etc). Ok this video is a rant on stupidy (-: sweet. A while ago i head a person could get grants if it backed climate change, but otherwise a lot hader to get a grant (we don't need people to figure out solutions, prove the problem might exist). People that have an active brain need to realize all governments are reactive not proactive and proactive people tend to avoid the accident, the others blame the wall for being in the way, crunch.
I'm not sure, but I think the human eye is a bit hyperopic for red light and myopic for blue light. Because of this, you can read the red indicator from a greater distance.
I am loving it diode gon really wild also your cat ❤😘🥰🥰😍😍😘😘😘😘😘
Thanks!
Thank you for your support ;)
I've always thought that super caps are generally no good except for a very small number of special applications. Would be good to see a comparison of super caps vs NiMH/ Lithium Ion.
The clouds scatter the light from the sun onto the panel, open sky doesnt scatter anything is why clouds can give more energy, open sky (blue) doesnt reflect anything, its basically a reflection itself. Off Grid Garage's channel experieces this phenonemon with his solar setup, getting more on cloudy days because his panels arent in the sun, they're covered by shade from trees. But on a cloudy day these panels produce more then on a sunny day because they're getting ambient lights scatter from the clouds.
great video as always, even better when you start talking about things that the world must know but no one wants to talk about because it's unpopular opinion
In a low voltage solar system, there will be significant power losses in the zener diode. Would it make sense to use a logic level mosfet to prevent discharging the battery when there is no solar output?
I've been able to increase the output of my Solar Cells/Panels by 12% - 16% by shaving approximately 1.5mm off the epoxy coating.
Thanks for this informative episode.
Dany its a pity u cant tolerate longer videos. I feel like they always end just when yr getting up to full steam. Lol at team size and eating pets 😂 v v funny. Anyway instead of cleaning our filthy windows on my day off, im going to the "office" to open up our fairy lights little solar unit which ive had saved for awhile - under the supervision of our cats of course.
Ty as always for another great video
Instead of dark filter use a piece of electrical tape the same color as the display. It doesn't attenuate the light that much and still makes the display much more readable in bright conditions.
I don't think it's just your eyes. For many years now, I've noticed that I have a lot more trouble focusing on blue lights at a distance in the dark than I do red lights. Green lights are somewhere in between. I suspect the optics of the human eye have more difficulty focusing on shorter wavelengths.
I like your accent, it sounds like a combination of bisaya and french
It really is a bummer about how fast the super caps self discharge. Does seem to limit their usefulness in so many applications.
I picked up a 5 pack of some nice, 250x250mm glass solar panels a few years ago, but haven’t figured out what I want to use them for 🤔. Maybe a few garden lights.
the self discharge is logarithmic and slows down over time. I had 6S supercaps charged to 15V and they self discharged to 13.2V after 2 months
@@Infinion Ah, I suppose that’s not too bad.
Yeah @@BRUXXUS I think the supercap needs to CV soak for several hours to accumulate all the charges in every nook and cranny, then self discharge will be quite low.
I'm using my small solar cells to keep small batteries charged so I stop purchasing battery replacements. Thin film and amorphous is the best for low light...
I use a projector as my main computer screen to avoid myopia.
I have a word about that vision thing. I can blur my vision whenever i want and when I'm watching youtube for example, when nothing interesting happens on screen I'm blurring my vision :D
You are just unfocusing the lens in your eyes bro. Nothing amusing in it.
@@maheen- i know that it is nothing amusing but because of that my eyes aren't constantly focusing on close distance and I don't have problems with them. Every optic told me that I have very good vision and I am spending a lot of time in front of the displays
You could use a charge pump regulator to double 1.5v+ with high efficiency, 90%+ ... and you keep complaining about voltage with the seven segment displays but it's all about the resistance you use to limit current going to segments. There are seven segment led drivers you can use to set maximum current per segment and which allow you to adjust brightness by pwm-ing the led segments. So you could have high brightness during the day and less during the night when running on supercapacitor or battery.
Never understand trying to use suppercaps as batteries! Batteries make much better suppercaps 🙂
if i want a battery that can provide sudden high current bursts then a battery with some supercaps in parallel would be great.
Woko Haram. Not a very bright perspectiv, for the near future of mankind, but you nailed it. Thanks for your Videos! Always an inspiration
I suppose you could get carried away, create an array of 100 super caps individually connected to a custom BMS which is charged from solar panels then with the caps connected in series to a buck converter power whatever the cat will permit. Nice.
Great vid.
"Green" today just means gullible and fearful of common sense.
I just don't see the application of Super Caps being much use in these low voltage applications. Using ANY lithium cells seems to just be the way to go. And you can even use your old OLD Tired Cell phone batteries that do still produce voltage but hardly any current anymore. That's what I have been doing with my old Laptop Cells.
They work PERFECT for these very low draw applications with a solar cell. So if you have outdoor Candle flicker type lights like I do? They work PERFECTLY to keep the Batteries topped off at 4.2v or so.
I'm going to experiment and see if I can just run them with nothing but A Diode and a solar cells. I have not got around to it since the 18650's I use do such a nice job as is. And last about 2 weeks before I have to recharge them.
Love your comment about the “teams of experts “!
Making some great points here.
Není lepší za cenu těch komponentů udělat obvod na 9V baterie? Kdyz se použijou dvě paralelně tak to vydrží podle mě hodně dlouho. A cena jedné 9V baterie je kolem 40kč. Ty solární panely museli stát víc než 300kč spolu a nepočítam superkapacitory. Doma mám jedny hodiny co ukazují všechno ( roky, dny, hodiny, minuty , vteřiny, datum i s kalendárním týdnem pak teplotu venku kde je samostatně senzor napájený 2xAA, tlak, vlhkost, teplotu uvnitř, vlhkost uvnitř ) a má ze zadu i takovej jakoby 3,5mm jack na sluchátka ale je to k napájení přes solarni panel a rozsah je tam od 4,5 do 10V. Do samotnych hodin jdou 3xAA baterie a kdyz se tam dají nabíjetelné, v menu hodin stačí zmáčknout že se používají dobíjetelné a uz samotne hodiny dokážou regulovat i nabíjení skrze ten solární panel. Ale každopádně super video ako vždycky ❤
Ty tvoje hodiny zní zajímavě! Prodávají se ještě? Neměl bys odkaz?
Awesome roast for a starter! 🎉🎉🎉😅
Good job, can u sent circuit layout.
Use solar cells to power a joule thief, to charge all the caps in series, a small buck regulator to power your mpu?
Well, why not, but it seems a bit overcomplicated for the purpose. Also the efficiency of these things on a very low power scale isn't that great.
@@DiodeGoneWild or use a reclaimed vape cell?
Czemu nie masz większych paneli solarnych?
Too much trouble when a nimh and a diode will work fine. And the battery also becomes the voltage regulator
Thanks

throughout the whole video. He is roasting this idea and setup, how it is impractical. Yet explans every small detail to make it work technically.
I don't condemn anything without properly testing it. And of course, even if there is a more practical solution, it doesn't mean that this thing can't work :).
😅 A solar freakin roadway... 😅
Thank you for your support and appreciation ;)
Wait:
What if you take the solar freakin' roadways, plug that into a super capacitor, then feed that into a Batterizer, then feed that into an LED light that shines on the solar freakin' roadway. You'd have infinite power!
It's LC-Display, or just LCD. LCD-Displsy is wrong
Can you do a documentary on your cat?
The most important takeaway from this video is the greater need for one person of each ethnicity, over people who know what they’re doing.
It doesn't work like that. You hire two or three specialists then some farming equipment and an assault helicopter. This is how you create an inclusive and diversed team.
Real
@@yeahbucka3005
The “experts” and the “attack helicopter” lingo I get, but...
Hire some “farming equipment”?
...
Oh, you mean black people, of course, this is what I came to expect on a channel about electronics.
make metals, use ethanol-koh carbon felt metal-air fuel cell
make blender graphene super caps with milk whey in water and graphite
make diy plasma solar cells, with two dissimilar metals electric field over a semiconductor or plasma, like heater air over a fire or inductive heat, well solar heat plasma solar cell
if you shoot solar photons on a surface, the surface becomes charged and conducts electricity, like in a diode or transistor
get a suitable pure source of silicon metal, then use electric/magnetic field to steer ionized plasma to super ultra pure silicon on wafers, or just use the electric/magnetic field to separate various materials in small quantities directly and grow ion bombardment crystals in vacuum
braiins..... :)

what about green hydrogen?
The major problem with hydrogen is that unlike other gas fuels it does not easily liquefy under pressure, so you can't store it in a cylinder like propane for example. Storing and transporting it is the big problem--I'm sure people have been thinking of solutions though.
@@rfmerrillHmmmmm, i thought that the by-product of burning Hydrogen was basically clear water. If it green, is there some form of algae affecting it ??????😏
@@brucepickess8097 Did you mean to tag me? I don't know what @inseries5494 meant by "green" hydrogen.
@@rfmerrill Sorry not you, I'll repost to the correct recipient. It was a humorous comment.

Apart from agreeing totally with your rant, I was wondering if you have ever played with those capacitor driven motorised toy planes, and what hacks you might be able to achieve just for amusement ? (sorry I can't afford to be a patron, but I an a crippled OAP and finding it a bit of a financial struggle, so my computer is my contact with the outside world) Thanks !
After the ship full of cars burned, internet is buzzing with questions about what to do to prevent more fires while shipping electric cars. I wonder how many politicians it will take to realize that simply shipping with the batteries separate from the vehicles will solve that. The batteries are replaceable anyway, right? Ha. we’re doomed.
That isn’t a decision that is going to be made by politicians.
Don't question the narrative
In my day ballbags used to carry men's testicles, nowadays they are running countries and making really stupid decisions. We are all fucked under these idiots.@@MrGuano11
So teleport the batteries?
According to dmt-Puls, the 500 electric cars were stored in the 4 lower decks ... that were not damaged by the fire. Google (translate) "E-Autos wohl nicht für Feuer verantwortlich" ... and draw your own conclusion.
Please... Clean the window.. Or change the cat !!!
Vídeo jewel
I love your commentary... 😂
I'd be really careful with such introduction these days
People being really careful led us into the nonsense of these days...
@@DiodeGoneWild Chapeau! 😎
@@DiodeGoneWildwell the unfortunate thing is that social media is not conducive to turning these conversations productive. You can see that the majority of comments here are saying they agree with you. Is that because most of your viewers already agree with you, or because people who disagree did not comment? Personally it made me a little hesitant to engage because I suspect people will just dogpile me if I disagree with you--as often happens.
For one example where this happened was Dr. John Campbell's channel during COVID. He made some expressions of personal disagreement with some things respecting how Ivermectin was being considered. His opinions themselves were totally reasonable, but they rapidly led to his comment section becoming flooded with anti-vax conspiracy theorists praising him, and people outside those groups stopped watching his videos as much.
The hazard with expressing these opinions is not so much that it will hurt you in some way--in fact it could even lead to more success for your channel. The hazard is that it may narrow your audience to just the people who agree. It doesn't really bother me that you said what you said in this video, even though I may disagree with it. But it does bother me how half the comments on this video are people praising you for that commentary instead of talking about the core content of the video. I don't like to spend time on channels that become nasty cheerleading teams like this.
@@DiodeGoneWild Based chad 👍
@@rfmerrill It's because in Eastern Europe you can actually say this freely and everyone would agree. It's considered normal to say this, not like in the West.
Always spot on with your commentary on society.
the discharge curve of a cap (12:50) is a straight line, just in case when you're discharging with constant current
..wrong / totally wrong / or something else? .)
yes, I probably forgot to mention that it's at a constant current discharge.
1:12 😂😂😂
That’s a good old whinge about the state if the world. I do agree. As for the project doesn’t it just prove you cannot have a solar powered design that works in various conditions and isn’t over-engineered so it’s better to use the mains and have some proper grid-tied solar panels on your roof.
Merci !

Welcome to Eastern Europe.
@@cezarcatalin1406 Well, looking at how popular the AfD has become in Germany, how Britain exited the EU, how Sweden is ruled by Right-wing nationalists, ... Western Europe is going down the drain too 🙁
well if you use the suns energy more you wouldnt be spending trillions on fighting for oil and territory and would have more money for food maybe? its more then fashionable i think its called energy independance. Maybe spend that money on exploring the universe. Imagine if we could use more the 20% efficiencey. That with superconductors would bring peace on earth. Everyones just fighting for energy... and theres tonnes of it free in space.
Sun energy definitely isn't bad. It surely helps a lot. I just mean that it can't solve everything. Especially the storage on a grid level scale is just a concept.
Over half of California's electricity is supplied by wind and solar during the daytime, so it makes a huge difference! But as Danyk points out, we still have not solved the problem of storing it, so our net demand still has a big spike around sunset--when everyone is getting home from work, aircon is running because it's still hot, but solar is falling off.
as I type this right now, CAISO reports total demand at 25,244 megawatts, and of that 12,582 megawatts are supplied by solar! The graphs show that there are some large battery banks that supply 3000 Megawatt at peak during that sunset demand, but the gap still has to be made up by natural gas.
Renewable energies will be good for the planet if correctly done but will never be free for citizens. Nobody fights for energy, they fight for money, solar energy isn't free, the panels, inverters, batteries, wires, etc. don't grow on trees, haven't you noticed that the oil companies themselves are becoming the owners of most of the renewable energy industry?
They are trying to buy all those companies like they're trying to buy all the lithium mines and so on, we will continue to depend on the same companies that control the oil market even if the cars use batteries, fuel cells or any other alternative power source.
