lol - well two things got from the video - win win lolol

that's a good idea mate - cheers

Thanks @@ThinkingandTinkering, very occasionally, I do have them.

for sure mate and cheers

cheers mate

no they don't produce much - be good to preplace them with actual solar cells for sure - but it is interesting

cheers mate

do you know - it really is lol

cheers mate

that's a nice tip mate - will do - cheers

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.

cheers mate

lololol - go for it mate it is one of my faves

solar thermal?

@@ThinkingandTinkering , high temperature thermal - Helmholtz, not Gibbs. See Langmuir's work with GE "battolysers" (hydrogen).

cheers mate

wow - cheers mate

cheers mate

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.

awesome lol

cheers mate

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

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?

indeed

wow - brilliant mate - that I am going to try

yeah it is only from front to side mate and I like the joule thief - good for stepping up low voltage to usable voltage

there are good reasons - I thought I might do a video on that mate

you could leave it fixed and get good power throughout the day

for sure

glad you liked it mate - cheers

never thought about that - true enough

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

it did make some nice refractions patterns in the sun

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

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.

ok

I like that idea mate - thanks for sharing

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

I don't know - good point

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 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.

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

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

yep and they can be so useful to the creatively minded - nice tip mate cheers

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

Speakers can be used as microphone. So...maybe

I have no idea

for sure mate

yeah I think you could - it produced a surprising amount

ok

for sure

ok

indeed

lol
