This uses carbon nanotubes, which can have asbestos-like effects on the lungs. Nanotubes are great for tons of applications, but especially those where safe disposal procedures are possible.
If these are a replacement for LEDs with better properties, these would be widely deployed in everything from lighting to devices. I wonder whether at that scale this presents a safety challenge, given the probability of breaking and the way people dispose things. The glass substrate does hold them in place, but what happens when the glass breaks in all the myriad ways it can in real life?
- zakki 4y agoI am just excited as others when reading the TLDR comment. But this warning made me think of do I still want it? Is there anything in the paper explaining about the safety of nano carbon they use?
- jiggawatts 4y agoWhen there's articles about Gallium arsenide (GaAs) semiconductors, you get the same comments. "Arsenic is a poison!" Yes, we know. Are you cracking the chips open an licking the semiconductor wafers inside for their flavour? No? Then you have nothing to worry about. This is the same category of thing. There's micrograms of carbon nanotubes in these lights as a thin-film inside a very strong ceramic casing. Unless you're smashing the thing open and then scraping the surface so you can snort it with a straw like it's cocaine, you'll be fine.
