I didn’t realise LEDS would generate.
I also didn’t realise that Daffodils could be weaponised like that 😳
lol - well two things got from the video - win win lolol
Presumably, you could waterproof the LEDs/solar cells and just keep that end of the panel in some water to keep them cool and maintain a high efficiency.
that's a good idea mate - cheers
Thanks @@ThinkingandTinkering, very occasionally, I do have them.
I did not know that, that if you shine light on a Led it would generate electricity. I have learned something today, thank you Robert!
cheers mate
Would be interesting to see what a panel made from led tape lighting strips would produce. Interesting video as always.
for sure mate and cheers
That's impressive. I never thought you could run a fan on that. I have seen a few projects where led's are used as photodiodes but always for measurement of light. Not for power generation. Good one !
no they don't produce much - be good to preplace them with actual solar cells for sure - but it is interesting
thank you professor Robert, I love your videos! mainly about solar energy!
it's awesome how some things can be repurposed to do something other than what they were originally designed, and often quite easily. great video as always.
cheers mate
Outstanding Robert! Magic!! Thanks.
do you know - it really is lol
Wow! Pretty neat 👏
Thanks for sharing! 👏
cheers mate
Take a look at antenna pigments as in plants. Shifting the absorption emiision to harvest able frequency of cells
that's a nice tip mate - will do - cheers
I recently came across a deskcycle by 3d innovations under the desk exercise peddle device. It uses magnetic hysteresis damped disc with a few pulleys to increase the speed of the disc. It will lend itself to a good generator build because of the 1:~25 pedal ratio. Keep an eye out for one. Love to see your take on a build. I'm looking at adding magnets to disc passing added coils or adding a pulley/chain to drive external PMMotor. Love your work
another good one mate - cheers - I will also be looking that one up lol
Always enjoy your videos...knocks the cobwebs out from between the ears....carry on.
The hot side of a refrigerator and a closed loop cycle of Langmuir torch - perfect solar power collector.
solar thermal?
@@ThinkingandTinkering , high temperature thermal - Helmholtz, not Gibbs.
See Langmuir's work with GE "battolysers" (hydrogen).
A, poke up the where with a what now? 😂 Never heard it expressed quite that way. Full on belly laugh. Thanks mate. Awesome
im loving all this thanks
cheers mate
Brilliant!
cheers mate
Will I build a LED solar panel over the weekend? Most likely not. Will I use the Sharp Daffodil comment at work tomorrow? Yes!👏👏👏
lololol - go for it mate it is one of my faves
I wonder if these light channels would help speed up the charge time of the Prussian blue battery? Maybe make the PBB a tower or tube and use light guides to divert sunlight through them to charge. Kind of like a tree 🌲.
wow - brilliant mate - that I am going to try
Ooo 1648, maybe another of my favourite numbers as its the amount of chapters in the novel battle through the heavens.
awesome lol
So... LED’s go both ways... the old “in and out”... cool.
They could be called light absorbing diodes😱
@@Buzzhumma photon absorption
isn't it - all semiconductors will do this - you can do it with old transistors too
@@ThinkingandTinkering you mean the can top ones?
What if you inverted that piece with the diamond shapes on it and placed it on a regular solar panel? Would that not gather light from various angles and send it down to the cell? It may block some light from directly over head as it is not totally transparent but maybe that difference could be made up for and more if it gathered light from multiple angles as the sun passes over...like a stationary sun tracker of sorts?
That's what I was thinking too ! 👍
A solid state solar tracker.
No moving parts.
@@kevinleebailey Exactly.
kind of like a fresnel lens? well of a type? I don't know - I must try it out
Very good content sir, my only worry is that in a hot country the plastic would degrade very quickly and its light guiding properties Will be los.
probably - I believe there are glass versions of light guides - but I have no idea where you would get them
Yes i think there are plexi glas versiones but very very expensive. Let hope there are cost efective uv resistant plastics. Any way excelent news, thanks again sir.
If these can capture light better "off-angle" then several vertical "Slats" could vastly improve the power generated in a smaller footprint.
you could leave it fixed and get good power throughout the day
for sure
Hi Robert that was really interesting as your video's always are. I wonder if you have any specific knowledge tucked away in your vast brain on solar panels for diffuse light. I am moving to Shetland hopefully soon and for 8 months of the year the light can best be described as "diffuse" 🙂 If you don't have time to reply, that's fine, I will still love your channel. Best regards Sarah
So, for DIY, would you use this light panel, w/ 2 strips of Gallium Arsenide solar cells, to get a CPV + GAPV solar panel?
Great video this is a teacher given us all jewels here. 👍👍👍 what is the actual name for the super white reflective plastic that shoots the light back??? And the light guide & light diffuser plastics can they be purchased... sir can you make a video about how does light guide & light diffuser works. Thank you & much success to you & all your projects 👊🇨🇦🇬🇹👊
I have taken apart square led light panels in the past to see how they operate.
I am very impressed with this idea and am wondering why big tech is not persuing this methodoly in the manufacture of pv panels if it means greater efficiency?
there are good reasons - I thought I might do a video on that mate
gran idea amigo, si lo piensas, es logico. gracias por el video.
cheers mate
That reflective white panel may be infused with reflecting crystal like material that makes it more so.
it did make some nice refractions patterns in the sun
Very interesting Rob. Thank you. The first question is about fit. The smallest cells I found were 30x25mm. That still seems to big to make that fit at the edges. Sounds like some adjustment would have to be made. Unless I'm missing something. I didn't have coffee today so that has high probability! Thanks again for all that you do.
A quick googling doesn't turn up much, but I bet there's probably some specialist provider of parts who'd do you a thousand little strips meant to go in pocket calculators and such. Or maybe a small handful if they offer "sample" packs.
Just a suggestion, I've not given it a ton of thought; but how about 2 such light guides stacked? (No reflector in the top one of course)
@@TheBaconWizard
Or more.
@@kennethjessop6073 Possibly, yes. Obviously it would reach a point of diminishing returns, quite quickly I think. But anyhow, the cost of making the entire panel the same thickness as an of-the-shelf high efficiency solar cell might not be too much.
I have one in my desktop calculator that is only 10mm wide mate - I did find 100 12mm by 38mm panels on aliexpress for UK£9
Windows are a huge source of energy loss, but they also save energy by letting light in.
If we used a lens to focus the light into a fiber optic cable and then put that same light back into a diffuser, we could get the same amount of light without the heat loss and the amount of light could be easily adjusted from 0-100% at the optical coupler.
Even if you only used lenses, like the rectangular, flexible Fresnel lenses, you could increase the area of insulation by over 50%.
DId you read Ikaru
I recall light-guides like this as an alternative to skylight windows... And, having once had a normal skylight window installed, I can vouch for the amount of extra heat all that sunlight created, radiating off the new walls in the attic.
I dunno about replacing windows, in general, but for ceiling-lighting, it sounds great... can even be brought through several floors, or maybe even between floors from panels on outside walls.
there is a lot of research in this area for exactly that reason mate - it's called integrated solar I believe
great informative video as usual.
does the filter only direct the light from the top & bottom? as that's where the LED's were. if not could possibly double power using the sides also? with LED's as receivers.
if i may ask whats you thoughts on Joule thief circuits ?
yeah it is only from front to side mate and I like the joule thief - good for stepping up low voltage to usable voltage
Very good
cheers mate
Is there any way to use a pyramid on the edges? So the panel is 5mm but can it be extended to 50 mm
No fire no fuel no problems, raise water without effort
indeed
Hii sir huge fan of your ideas
wow - cheers mate
So are you saying that I can put the telly outside in the sun all day and bring it in at night and just watch it for free? Come on surely not ! 😂
Ha ha ha u will be frying your telly
lol - in theory I guess so - in practice I am not so sure and you might be able to watch it for say 1 minute or so lol
What happens when you fuse the edges together of two such lenses, but 180 degrees, so one is flipped over? Does it act like a periscope? Can it be used to bend light around objects?
At the same time, it will reflect heat away from the house, good for summer.
never thought about that - true enough
you could try a difuser on top of a solar panel that distributes the light evenly with no direct sun light. Could reduce heat significantly. Output ????
I like that idea mate - thanks for sharing
Have you sir perhaps tried any food preservatives (antioxidants) in preparation of a dye sensitized solar cell?
Also, what about mixing two different dye types (anthocyanin and chlorophyl) to increase the absorption spectrum?
I haven't tried mate
@@ThinkingandTinkering
That's a bugger, were hoping for some feedback. :)
How about these do-it-yourself dye sensitized solar cells you've been talking about in previous episodes? Are these serving you well?
Frankly, I'm asking because I can get a hold of a van full of LCDs for free, but the catch is, I either take the van, or I don't take any at all.
Wouldn't really want to get stuck with a bunch of LCDs without a purpose, lol.
Thanks there.
thats cool nice one m8
glad you liked it mate - cheers
Add more LEDs on second and third strings ? to triple ampage
The easiest and almost the cheapest way to get low powered solar panels is to harvest them from solar garden lights.
Will it work if we stick a solar panels on that shine the LED on the panel up close with same backlight
I would think so - but the power loss through that would be huge
@@ThinkingandTinkering you see Rob getting 12v is more than enough for inverter, connect the 60w led strip to a panel size acrylic board, stick violet colour reflective sheet to the acrylic board if we shine led will it work
@@ThinkingandTinkering and also some way to put cold water circulation under the panel, fix a water tank under the panel
You can't get better than capillary action to raise water, gravity turbine, raising Arizona
ok
In the previous video, there was about a 10,000% increase of space needed to concentrate the light in a small area for a 50% gain in output. If space isn't an issue or the intention is to just run a very small solar panel, then it would work great.
you know the previous video was just a report on what is being researched - you can just look it up on google scholar - what you are saying doesn't sound right - but I will check it out - or you could confirm it if you felt like it
@@ThinkingandTinkering I was a bit uncertain as well. I meant to comment, on the other video at the time stamp of 5:26 . It would take a lot of typing to put everything into context, but I'll give it a shot. Using the diagram at that time stamp, let's say that you have a 1 inch or 2.54 cm square area of concentrated light. The area needed to concentrate that light is 100 inches or 254 cm. That's where I was getting the 10,000% increase in area. I know the drawing at that time stamp was just an example, but it's still going to take a much larger area of space to concentrate the light. A second 1 inch or 2.54 cm panel could be used to double the output, while saving space. Depending on the application, that increased area could create a shading effect on surrounding plant life; hampering the production of oxygen. Snow could pose a threat to solar concentration, where as, the black surface of a panel helps melt snow and ice. Solar concentration might improve electrical generation at night when certain phases of the moon are brighter. In time, the technology may improve, and require a much smaller space to concentrate the same amount of light. I can see how this might work in various applications, but I see the drawbacks as well. I don't know if that helps, or maybe I'm still missing something.
These days old (LED)LCD Tvs are basically free. People throw them to the trash and buy a new one when they brake.
yep and they can be so useful to the creatively minded - nice tip mate cheers
Could you put them over a panel and improve efficiency?
I don't know - good point
I like the video
Please tnt
I want to make an induction heater i have only 5 of bc 547 transistors will it work. Without Mosfet transistors
the power dissipation on those is only 500mW isn't it? - an induction heater uses a lot of power - I think you are likely to burn them out mate
Why not add more LEDs and a boost converter
I like it that they are white.
I really appreciate your videos but often I find myself puzzled not understanding or thinking somehow I missed some steps.
I am electronically challenged and I am trying to learn from you creative ways to produce electricity because I live offgrid and am trying to wrap my wee brain around it all
for sure
if something really captures your imagination mate it is always best to have a read around it - it helps get hold of the ideas
the most important thing is trying mate - you get there sooner or later
I had no idea you could get even usable energy out of LED''s that way! That's some Cyber-Punk stuff right there...
for sure mate
Without going to gan you could use the one from calculator several of those, they are 24% efficient
that's a nice idea mate - you must be able to buy those bulk - I have a solar calculator right here on my desk and the solar panel is one 1cm wide - I wonder where you get them?
@@ThinkingandTinkering websites like rs components or farnell or mouser, they are electronic components for prototyping
So, does this mean the broadcaster could see us watching tv? Or listen?
Speakers can be used as microphone. So...maybe
I have no idea
Great video I had no idea you could make electricity that way. Could you get enough power out of that to charge a cell phone?
yeah I think you could - it produced a surprising amount
I've been wondering why solar panels don't use facets from the gem industry. They've been figuring out how to channel light for 1000s of yrs.
I would use cd's
Imagine a floating pyramid raising water to let the water fall to turn a turbine, for nowt
indeed
Would also be cheaper to recycle
for sure
Blinded by the light, give up your mind
ok
Wearing a mask for the future 😉
ok
Cap Hilary
lol
Love the clickbait thumbnail. Didn't know they had solar panels in 1648 😕
