WhiskeyDisk 12/01/19 12:57:18 AM #1:	STOP. EVERYTHING. https://www.sciencealert.com/physicists-identify-a-metal-that-conducts-electricity-but-not-heat/amp "Researchers have identified a metal that conducts electricity without conducting heat - an incredibly useful property that defies our current understanding of how conductors work. The metal, found in 2017, contradicts something called the Wiedemann-Franz Law, which basically states that good conductors of electricity will also be proportionally good conductors of heat, which is why things like motors and appliances get so hot when you use them regularly. But a team in the US showed this isn't the case for metallic vanadium dioxide (VO2) - a material that's already well known for its strange ability to switch from a see-through insulator to a conductive metal at the temperature of 67 degrees Celsius (152 degrees Fahrenheit). "This was a totally unexpected finding," said lead researcher Junqiao Wu from Berkeley Lab's Materials Sciences Division back in January 2017. "It shows a drastic breakdown of a textbook law that has been known to be robust for conventional conductors. This discovery is of fundamental importance for understanding the basic electronic behaviour of novel conductors." Not only does this unexpected property change what we know about conductors, it could also be incredibly useful - the metal could one day be used to convert wasted heat from engines and appliances back into electricity, or even create better window coverings that keep buildings cool. ... Interestingly, when the researchers mixed the vanadium dioxide with other materials, they could 'tune' the amount of both electricity and heat that it could conduct - which could be incredibly useful for future applications. For example, when the researchers added the metal tungsten to vanadium dioxide, they lowered the temperature at which the material became metallic, and also made it a better heat conductor. That means that vanadium dioxide could help dissipate heat from a system, by only conducting heat when it hits a certain temperature. Before that it would be an insulator. Vanadium dioxide also has the unique ability of being transparent to around 30 degrees Celsius (86 degrees Fahrenheit), but then reflects infrared light above 60 degrees Celsius (140 degrees Fahrenheit) while remaining transparent to visible light. So that means it could even be used as a window coating that reduces the temperature without the need for air conditioning." If I'm reading this right, they've basically found a high temperature superconductor that can be customized. The possibilities boggle the mind... --- The SBA has closed for business, we thank you for your patronage Assassins. ~there's always free cheese in a mousetrap. <cite>WhiskeyDisk posted [p:930938795] in Physicists...

Think leds were invented in like the 50s and led lighting hasn't been in use that long. I'm still waiting for graphene to make a big splash.

Not every technology is Tang and Velcro. If it's not listed here above lithium ion batteries, it's not as energy dense, which means it's an inferior battery. Lithium ion is the standard for a good reason. There's a good reason to be skeptical of anyone claiming their new battery is more energy dense than lithium ion, because there are many, and most (all) of them are bunk. https://en.wikipedia.org/wiki/Energy_density --- https://www.youtube.com/watch?v=jZNqaAh6iLU <cite>Yellow posted [p:930969695] in Physicists...

We all live in a Monty Python sketch where a terrorist attack was just thwarted by a guy with a fire extinguisher and another armed with a fucking narwhal tusk. Not every technology is Tang and Velcro.</quote>If it's not listed here above lithium ion batteries, it's not as energy dense, which means it's an inferior battery.

Until this kind of stuff actually hits the market, I'll remain skeptical. Holy fuck, this. You would have subsided the buggy whip makers and said "fuck the transistor!" Because it wasn't in production yesterday? Nikola Tesla's technology was also ahead if it's time by leagues, but if it wasn't stolen by Edison, do you have any idea how many other technologies would have had crib death if we let Tesla go nuts with his wireless power system? Let's start with am/fm radio. Wi-Fi. The cellphone. GPS satellites If we'd jumped on Tesla's wireless power transmission technology we'd literally have sacrificed the entire radio spectrum to it before we had any idea what we'd gone and done. --- The SBA has closed for business, we thank you for your patronage Assassins. ~there's always free cheese in a mousetrap. <cite>WhiskeyDisk posted [p:930971719] in Physicists...
