I'm surprised that the light remains internal to the fiber. I would have thought with the resin it would be bleeding out light and very little would come out of the end of the run. I didn't think the light would bounce internally like a normal optical fiber. Nice job!

+GREENPOWERSCIENCE I wasn't able to find a link to the resin you're using for this on your website, and the LED source just links to a generic search on ebay. I thought youd have listed the best or very good suppliers

Thanks so much for sharing your findings. Have you found any super-flexible resins/urethanes? Looking to make short cables for use in goose neck sheathing.

you can fill tubing with silicone and blow it loose with the compressor when cured to make your own gasket orings. 1st time seeing someone do fiberoptics however.

Very cool idea. Thanks Dan!

Well done, thank you for the info.

Hi Dan, Thanks for this video. I'm interested in fiber optic for the use of transporting sunlight to a dark room for growing plants. Do you have any information about the effect on light spectra, efficiency of this resin and potential decrease of efficiency with increasing length of the fiber?

Amazing stuff!

You should make some transparent concrete bricks with this. It's just concrete poured over fiber optic cables or marblized with resin to look really cool and let light in from the outside!

Oh, additionally, I thought about making a passive sun clock with transparent concrete. It would be made of multiple bricks, and each brick would have the cables laid at a different angle. Each angle would grab light at a certain hour of the day. You could even shape the cable into corresponding numbers. I thought just color coding the cables would be neat and mysterious to everyone else. You could form it into a wall in your house perhaps or make a scaled down version just for outside.

Cerebral G'day, Well, there's a simpler way to do it, known as the Sundial which detects Genius Children, because both Isaac Newton and Christopher Wren apparently constructed Reflecting Ceiling Dials for their Bedrooms when they were 13, both without having ever been told the idea was known to be feasible... Place a high-quality Flat Mirror, level, on a Window-Ledge facing the Equator..., and calibrate the Hour-Lines Radially from the Reflected Meridian as it appears inverted on the Ceiling. If the building is Square with True North you can calculate and pre-Draw the Hour-Lines and smaller divisions..; but in most instances it'll be more practical to mark it by Observation, using Local Apparent Time, Zone Standard Time, or Daylight Saving Time as required, marking the lines on the Equinox... A Fibre-Optic Sundial for an Interior Room could be contrived, but it makes about as much sense as an Open-Cockpit Supersonic Jet Biplane, or having Sexual-Intercourse while lying on the Sand in the Surf ; it's a great image, and it sounds Really COOL, to anybody who hasn't got a clue what they're talking about. In my experience... Have a nice day, ;-p Ciao !

I'd like to suggest another way to remove the tubing using a trick some use to remove insulation from wires. Drill a hole roughly the same diameter as the tubing in a sturdy bit of wood such as a 2x4 that you can clamp down. Then, drill the sharpest screw in from the side of the wood with just enough of the tip penetrating into the hole that it scores the tubing without damaging the resin inside. This way, you can draw the tubing through the hole, accurately scoring the tubing and not the resin.

if you plan to do more than just once, make a little jig with a blade jut long enough to vur 1/10th mm short of the tubes wall thickness.

This stuff is interesting. How do you use these in practice though? Are there practical applications?

Another nice video well done and thanks

whats the name of the resine?

You could use " Vintage Ship Glass Prism Sky Lights" at the end of the pipe to disperse the light in your home vs only having the spot light effect.

Hello, I would like to make a uv cure resin at home for low cost. Is it possible? What items would i need? Thank you for the great video :)

Sunlight interferes with the hardening of the catalyst with the resin. Cure it indoors.

MIRROW tube, before resin u let tube aluminium (or like paint that) paint, thin layer (and let/suck other paint again out)(and let try) and then resin to tube ? Or paint after (irrigate briefly paint the inside out or sprying). Conuse/spring tube can make tu suck light outside? Or suck light with clear plastic bottle (with water (North side covered folium or alu.painted)) and fiber tube inside cap .

What are we using this for?

some UV set polymers can be drawn.

GREENPOWERSCIENCE --- Question??? what if you did not use resin with the pvc tube but insttead alumaplated the inside of the pvc pipe? then from the solar collector bounced it into said pvc pipe at a 45 degree angle? I mean angle of reflection = angle of refraction so it would bounce back and sorth like a saw tooth through the tube till all the light comes out the other side? .. I mean even if you have to split toe pvc pip in have to do the alumaplating... you could join it back together and it woldn't really hurt anything right?

Fiber optics transfer radiation. So, how much heat that is transferred from sunlight is determined by which wavelengths are transmitted. Some of them transmit in the infrared spectrum, and some are even fiber lasers.

Most of the sun's heat comes from the visible spectrum. But most fiber optics are designed to only transfer light in the infrared spectrum, which is pure heat but it's only w small portion of the heat in sunlight. Most of the heat in sunlight is in all the colors that you don't see reflected from an object, because they were turned into heat. If you could find a fiber optic cable that transfers visible light, you could then focus it with a lens and use the heat.

Have you tried to concentrate the sunlight and focus the beam at one end of the fiber optic line, send it to the inside of the house and reverse the process amplifying the light back then check how much infrared was transmitted throughout the fiber. If acceptable that could make a cool day light source.

Great video. :-)

Okay Dan, let's design a funnel to collect the 9-4PM sunlight and channel it down through a PVC pipe into a room. I'm envisioning a cut-away upside-down cereal bowl shaped parabola.

would this be cheaper than buying normal fiber optics. see i plan on doing this to a house so during the day the house will be lit up with the fiber optics.

brandonhughes7 The advantage to this is larger diameter and is good for shorter distances. If you are doing a long run, fiber cable is a better option. This works good for 8 feet or less. I would suggest trying a few DIY and see if it works for your applications.

Here's a thought: Is it possible to light up solar panel(s) having a light source in a different area that light cannot reach to power up a battery using the homemade fiber optic lighting?

interesting video. Thanks for sharing this. Have you tried to draw these fibers down to thinner cross sections? I suspect that these are urethane type polymers. A simple low temperature furnace, that heats a slug of cured resin to say 150 or 200C might allow you to extrude/draw the softened polymer out to a thinner cross sectional diameter. Lots of potential here for some very interesting projects! thanks again, Doug

nitrous dude The UV cure resins can be blobbed in a semi-shaded area then drawn out with a stick into the sunlight. This creates long fine strands that cure instantly up to 100 feet in length. A gravity fed system with a UV light source could also work for thicker strands.

GREENPOWERSCIENCE I think in practical terms, it needs to be thermally drawn, rather than drawn in a gel state. The idea isn't just to get small fibers but rather, small, coherent fibers that are individually clad in a material of differing refractive index. Your light carrying capacity would likely increase significantly if you coat the cured polymer with a low index of refraction substance. although air obviously has a much lower index, the surface of the polymer core will become contaminated, reducing internal reflection and so, efficiency. Ultimately, the idea is to create a "stacked" preform, which contains multiple clad fibers that are optically distinct so thermal drawing is necessary.

some resin, tho its vague which one he's using and the website isnt helpful either. Im wondering if there is a flexible polyurethane thatd be better than a resin. also the curing process is more user friendly than resins Im thinking

so during the hardening process direct sunlight makes bubbles.. so you could make several areas of the tube light up. this could be used for artistic optic light statues/installments. have you ever tried to expose just a limited area to direct sunlight? are the bubbles random ... or is the process like controllable?

elemental smurf Endothermic takes in energy in this case sunlight to start and control the reaction rate. Heat released from resin curing is exothermic but since the catalyst is continuous UV exposure the endothermic process is required throughout the cure. It is not like an MEKP catalyst. I did incorrectly state that the release of heat was endothermic resulting in bubble expansion when it is actually more exothermic.

Love this content,i need to make optical cable and set it up so that it goes from my roof to my room and i need DIY parabolic mirror dish to focus light into this optics with IR filter because of heat.I need light in my room,as my room window is not getting any light because of terrace in front of my room.And possibly put few photo-sensors to measure light brightness and move dish accordingly towards more light with some arudino and programming(sun is the source).What do you think about that?And does it help to transfer light better if i wrap pipe with alu foil if pipe is transparent?I know wrapping it wont bend light properly ,but will it help somewhat?I probably wont make that it moves because that would require more money for motors.
