> still cannot buy graphene in any real quantities (cm's for $100's) I’ve never needed to buy graphene before… why would most people? Not every technology needs to be applicable at home for it to count as “not vanished”. Upon googling it, I found this source for about $1/cm^2 of graphene, which is 100x cheaper than what you seemed to be claiming: https://grolltex.com/product/monolayer-graphene-on-copper-foil-6-x-6-150-mm-x-150-mm/ https://grolltex.com/product/monolayer-graphene-on-copper-fo... Regardless, one recent product announcement I remember hearing about, which can apparently be bought on Amazon for $13: https://www.thermal-grizzly.com/en/products/625-kryosheet-en https://www.thermal-grizzly.com/en/products/625-kryosheet-en Graphene is real. It hasn’t vanished. It just takes a long time for a new material to become widely used unless it fits neatly as a substitute for something else that was already there. By all appearances, the graphene industry is still growing. > Thermal Cameras Seriously? Thermal cameras are commonly used in so many professional applications. They’re not even that expensive, if you want one. No, every smartphone maker is not going to add 5% to 50% to their BoM (depending on quality and phone price, rough estimate) for a feature most people don’t need. Some smartphones offer thermal cameras for people who need that.
