Years ago I made a heated motorcycle vest. I used 30 gauge 7 strand Teflon coated wire. I think I remember that 20 feet of wire at 12 volts has 100 watts. So for less than $5 and that price of a vest, I had a $100 vest. During WW2, they used that same technology for heated flight suites.

After watching your video I bought some of this. I use it inside a small LiPoSafe battery case to keep batteries warm. I feed 200mA/1.5W through a 1m piece using a constant current supply. The voltage is around 7.3v when doing this. With this power the wire reaches about 15-20C over ambient which is great. In use it generates just enough heat so that the small case stay warm when also inside a camera bag. I also tried using the wire directly across a 2S protected Lipo cell which works great and is more often used. Current starts about 8.4v/230mA/2W and drops off from there. The battery protection providing a safe cut-off when needed. The advantage with this is it's just a wire and a battery. No extra stuff to go wrong. Running off a 3S Lipo pack the power is 12.6v/350mA/4.5w which brings the temperature up to about 40-45C above ambient. I terminated my wire by soldering a wire to a diode's leg off-cut and pushing it down the insulation tube. Tightening the sleeve with a cable tie made the connection pretty solid. I covered over the ends with two-part Epoxy. Thanks for bringing this to my attention. Added more in response to someone below... Just did a quick test: 1M of filament tested at a room temperature of 20C. 4 turns of filament looped about 8cm diameter sitting on the desk in open air. K-Type thermocouple taped to the wire. Voltage/Current/Wattage/TemperatureRise: 8.4v/230mA/2W/+20c 12.6v/350mA/4.5w/+35c 20v/590mA/11W/+85c 25v/750mA/19W/+125c Started to smoke slightly. Maybe was my heatshrink giving up. :-) 32v/1A/32W/+ 170C... Yeah. Unhappy heatshrink was smoking nicely.

Air filters also work. Your car uses a folded up air filter to get more surface area, because the folds and bumps increase surface area (which is a good thing for a filter). If it was just a round sheet, it wouldn't be nearly as efficient or long lasting. Same with sponges. All the pores and space inside increase the surface area and ability to hold water.

I just started watching this channel. I love it! It's like box unwraps except with things actually interesting.

" Should I be breathing this in?" *Inhales deeply*

Lets say you want to put this cable in a house of 100 m2. If you make a distance between the cables 10cm, you would need 1000m of this cable. Lets say I want to run it on 4w per meter. I expect with 4w the cable would be 30°C. And if you spread it with 10cm, the tile would be around 20°C. If 1000m of this cable is heating, that would be 4w×1000m=4kW If you run this 5 hours a day for a month, its 4kWh×5h×30d=600kWh If 1kWh is 0.20 euro cent. That would be 120 euro a month. But you probably dont have to heat up the whole house for 5 hours every day. Benefit of Infrared heating is that you only have to turn in on in the room you are in, so lets say we are warming up 25m2 for 5 hours. That would be only 30 euro a month. Dont forget, you need to set this cable up in a parallel connection. To make it 4w per meter, it needs to be 20m. So you need multiple cables of 20m setup in parallel connection. W/meter=U×U÷(m×Ohm)÷m =230V×230V÷(20m×33Ohm):20m = 4w per meter

Flammability test, you light the bottom and see if the flame propagates up after heat is removed. To pass the test, it must self-extinguish within seconds of the external heat source being removed. That cable looks like a flammability fail as it sustained a flame for far too long despite being held horizontally instead of vertically.

Teardown Dan His was obviously not the official lab test. Anyway, most regulations require stuff to self-extinguish in a certain number of seconds (like 30s), while other regulations demand they use the minimum possible amount of potentially toxic flame-retardent ingredients. So materials like this wire are usually manufactured at exactly the maximum permitted flammability.

@teardowndan5364

@John 94V-0 is by far the most common flammability standard in electrical applications worldwide and for that one, the sample burns vertically from the bottom and must put itself out within 10 seconds from removing external heat. That wire might be 94HB (horizontal burn) at best. I suppose that's kind of acceptable considering that it is meant to be put in cement/concrete floors where compatibility with concrete may be a greater concern than flammability.

Great video Clive, you always find such interesting stuff. Had not seen this wire before but looks like it has some possibilities. Thanks Clive.

Terminating is done by window stripping the end, as you do with litz wire, then wind a single strand of wire around the bunch of fibres. The excess can now be clipped off and the smaller ferrule slipped on and crimped. Although you don't normally do it, I crimp the plastic part of the ferrule as well. Thanks for the great Vids BTW.

Although this is an "old" video, I just wanted to share that I have had good results terminating this carbon fibre cable with "Wago 222 Style" connectors on 12v DC. (A lot easier than ferrule crimping, and reusable if needed). The Wagos are good for connecting fairly short lengths in parallel to get good heating on 12v. (Heated car seats, cold morning windscreen defrosting (place over the windscreen air vent of a cold engine with the fan running, etc.)

Well, this just cost me about $30 for six jaw crimper and ferrule assortment pack. Between Big Clive's videos and the machinist videos I watch, I manage to stay pretty well broke every month.

I love how intellectually stimulating your channel is!

I heard one researcher report that they were able to induce lung cancer in rats from fiberglass but they basically had to "pack the rat with the stuff".

Amateur astronomers sometimes use wire like this to warm up optics that are exposed to the night sky ever so slightly, to keep them from dewing up and obscuring the view. But those tend to run at 12V, only a couple of watts/m, because you don't want to have too much heat, which would cause turbulence.

Neat stuff! Fun seeing materials that were hot new future stuff some years back being put to somewhat mundane uses.

So that is what all that weird wire I have is! Thanks for teaching me Big Clive!

Interesting stuff. Awesome video!

This reminds me of how carbon spark plug wires are connected. I have seen various methods but most oftern the carbon fibers are folded back over the insulation and the metal crimp ends crimped over both.

I've read that silver glue is good for terminating carbon heating ropes. I also came across a rather unusual carbon glue, which seems to be very fine graphite particles suspended in a water-soluble adhesive. I have some carbon fibre strips (about 15mm wide, 1m long) and the carbon glue and silver glue both work great for connecting the carbon fibre strip to a copper wire or bus bar.

Fascinating! A doubled length of this stuff in the condensate drainpipe of a condensing boiler, fed from a 12 or 24 volt thermostatically controlled PSU would prevent freezing of the drainpipe and alleviate a common problem with this type of boiler in winter.

Another fascinating video Clive. You may be interested to know that there is carbon cement available. I think it’s epoxy based with carbon nanotubes mixed in. It is used to bond carbon fibre panels together in the aviation industry where we need a conducting joint for lightning protection and static charge dissipation. Perhaps it could be used in a ferrule to join the fragile fibre. Just a thought.

Reminds me of the 'Nightmare decorators of Lairg'. The 'Big house' I once caretook had booked them to plaster scollop the ceiling and wallpaper the living room and, as ever, they arrived at the very last minute to do the job, rushed it, threw plaster and wallpaper paste EVERYWHERE and left the night before the owners were due. So I had to pull an all nighter to get the place clean and ready for the owner. Every door handle, toilet pull, light switch, window handle and trapes up and down the stairs, even in the fridge? I had to clean and scrape off plaster and hard set glue. The windows were splattered and the dust from the plaster mixing was everywhere. They had clearly mixed in every single room for some reason.... BUT the thing that really really pissed me off is they had found a roll of mains cable and the box of plugs and sockets which the 'Mannie' had asked me to make up various extension leads with after this visit and he had told me where they were for. They had found that, put a plug on one end and a socket on the other then run a fan heater with to fast dry the plaster and wallpaper while the most of it was still coiled up. Two thirds of the roll just melted together like you describe and ended up in the bin. Bastards!

Looks like a great way to make the heated seats I want on my truck. That's one vehicle feature that once you've had it you need it on every one after.

Brilliant testing, thank you

For terminations we used to use a crimp that was similar to how you would make custom high performance spark plug wires.You would strip it and fold it back onto the rubber coating and the crimp went on top of that.It's tough to explain but if you've ever pulled a plug wire apart you'd understand.

so how many feet of wire per sq. ft./ or what was average spacing between passes? what are you using for power supply / thermostat? how many feet of unbroken wire vs. parallel installations? What kind of termination technology to cold wire did you use? Does anyone have a detail for installing this under click floor without screed or thinset although that could be the best for heat transfer, but I've also seen putative details with reflective layer under the cable, e.g. aluminum foil, and poly sheet over it and click floor directly but the cable is about an 1/8" thick so i don't know how it managed the load and if there are enough passes and the flooring runs perpendicular to those passes, perhaps that is still a simple and functional install. how did you hold the cable down before screed and tile were placed?

I did a ride along with a fire department for a shift and I learned that people used to put this sort of heating system in their ceilings. I don't remember why people thought you should heat from the ceiling down but I do remember them explaining how much of a hazard those systems are.

I live in the arctic. The big extra high beam lights on my car has a lip on the frame around the outer glass, where snow and ice will stick. Won't stick to the glass much, but it collects down in that lip, and then builds up while driving until it covers the whole glass. Not a lot of heat to go around, with a 35w HID bulb and a 8" wind-chiled glass surface. I got some 14 ohm/m of this stuff, wrapped 2 parallel lengths of this inside the bezel frame, and hot glued it in place. Heats up that troublesome lip with about 30 watts total, now the snow and ice melt before it has a chance to build.

A year or so ago I took apart a broken portable air purifier (not mine) intended to be kept in your car, and it had a potted box with what I now realize was carbon fiber strands in a rubber sleeve coming out of it - thanks for solving that mystery.

It's commonly used with Ionisers now. It's a perfect emitter.

An easy way to test for emergent fibres would be to immerse the coil, apart from the ends, in a metal bowl of salty water and checking for continuity between the bowl and the ends.

Would this be good for DIY heated seats? Most vehicles usually only have low or high. Is this just turning on and off additional strands or varying the voltage?

Sounds like the sort of stuff you wrap around water pipes to prevent freezing, interesting cord, there must be many uses for it :-D

The crimper is obviously a fast and conveniently used tool for terminating this wire. I imagine an optimal crimper would exert crushing force at the tip. Moving further back along the fibres, the force would decrease progressively down to next to nothing. Tapering serrated jaws would do it, if you see what I mean. At some point along the crimp, the force would be optimal. Great demonstration of a new product; thanks.

How toasty did your ferrule terminations get in the HOPI? Thanks, Clive, I hadn't spotted this stuff, but now know what my next camping heated blanket will be made with!

in the snow country frozen pipes come to mind and this would seem like a good way to just keep it warm enough to keep from freezing along with that wonderful temp control unit you found so accurate and easy to use (not) lol

Good speach. I enjoyed your English =) Thanks

Hmmm. How much flexing and bending will this stuff put up with before the internal strands are too broken up to keep working? It seems like some ridiculously useful stuff if it can survive some usage.

Just wrapped a 2m tape looked like made from four strands of this stuff round a pipe in my garage. Burst in the cold second time in ten years. Will eventually link up to a thermo-controller but for now is on a timer, on 15 mins in every hour... same colour too.

Use a ferule with a sleeve that fits the insulation, strip enough conductor to double it over to fill up the metal of the ferule, then crimp. Works like a charm.

I love it when you go off on a tangent XD

I'd suggest making sure that you leave plenty of spare for retermination. Also make sure that there's a working RCD to protect against electrical leakage, as you're using product of unknown safety standards.

so would you recommend this for heating up a wood laminate? or only tile? the ebay seller had this info: Product power calculation: (voltage × voltage) ÷ (resistance × length) = power For example: 12K carbon fiber 10 meters length (per metre 12K 33 ohms, 24K18.5 ohms) 220V × 220V ÷ (10 meters × 33 ohms) = 150 watts For example: 24K carbon fiber 10 meters length 220V × 220V ÷ (10 meters × 18.5 ohms) = 261 watts The above data shows that the longer the length of the heater wre is, the smaller the power of the heater wire is. (The product temperature is subject to actual use.) Multiple heating lines can be used in parallel, so that the power is increased! Length: (custom, recommendation of not less than 10 meters) 12K recommended to use 10-15 meters (12k outer diameter 2.0MM) power 150W-100W 24K recommended to use 10-14 meters (24k outer diameter 2.2MM) power 280W-200W Note: The heating wires can't overlap when they are used, and they can't cross. The overlapping overlap will make the local temperature of the heating wire higher than the melting point of the protective layer, and the temperature will be too high to burn the heating wire sheath.

I'd be cautious about using something like this in a practical installation. It would be better to use a locally sourced and compliant system.

@bigclivedotcom I am searching for some carbon heating wire to sew into my motorcycle jacket. Can you recommend something good for 12 volts?

This stuff would work, but you'd have to experiment with length and heat. You may also be able to find flat heat panels made from spun carbon fibre in a plastic lamination.

Breathing fiberglass is reasonably well studied. It can lead to "silicosis". I don't know how well carbon fiber has been studied for this, but I wouldn't be surprised if the relatively pure carbon is far more biocompatible than silicon dioxide. That's purely a guess, though.

I wonder if that would be good to use in jackets, blankets, comforters, the like.

You could wrap it around exposed waterpipes (and wrap insulation around the whole thing) to keep away the frost. (I had two brakages this winter; it's the bends and tabs which break, not the pipes themselves)

I love all the inshulashun talk.

I didn't catch the optimum or maximum current that should be applied to a length of this stuff. That is, what are the ideal and minimum cut lengths for 120 and 240 volts, if your goal is to produce good-to-maximum heat per meter of material without starting a fire?

It's really just for low level heat. I wouldn't recommend running it too hot.

Wow, those are really fine carbon filaments...! I've seen various things like heated garments that say they use carbon heating elements - I wonder what form that takes if fibers like this are brittle - in a garment, the heating elements would have to deal with a lot of flexing, and I'm not sure the pad material from the cheap heated fingerless gloves you showed in an earlier video would work for something like a jacket.

Is it safe for aquarium use

i insulated houses in the 80's blowing fiberglass through a 3" hose , i was very pretty sparkling in the sunlight.

Didn't you always end up with rashes ? -I can't look at it- I can't even think about it without scratching myself

no, for some reason it doesn't bother me too much.i have also used mineral wool that stuff is bad. if you get itchy from fiberglass throw a hand full of salt in a hot bath for some reason it works

Oh my god... How was the itching? I played with the stuff as a kid once and it was a week of itchy hell.

@Space Core ugh I used to work with fiberglass piping and insulation and the dust from either would make me so goddamn itchy I'd scratch myself bloody. I'm glad I'm nowhere near that industry anymore.

I agree about the fiberglass

Excellent candidate for "brew belts" (heating belts you wrap around your fermenter to keep them warm)

Can you tear down an electric heating blanket controller? I’m curious how the stepped heat levels how are achieved. Tis the season!

In commercial cooking systems we use this same carbon heater style in ribbons ,pads ,cables etc. Most are 24v ac and 110/120 v ac generally used on vat fryers ( French fry cookers and chicken products occasionally hands feet x wife's head the usual ) to keep oil lines , pumps etc... warm so they move artery clogging fluids for when oh I don't actually filter there once was cooking oil as opposed to the sludge that is smoking in there vat ( yes I do a lot of fast was food places and no I don't eat anything that comes out of them ) . They are also starting to show up in refrigeration . The connections are generally a heat bonded/Vulcan process from the carbon to a high temp silicone/silver wire pigtail lookup frymaster heating cable or pitco www.partstown.com or similar . I have a large one I use in the winter for my van seat and run it from a inverter ( Nebraska actually does get cold and I'm old. mother found me under the refrigerator in may of 1959 she said the milk man put me there)

BigClive Did you make that Hopi or buy it? It looks suspiciously like the case off a TDR - TL260 If you bought it, where can I obtain one?
