Scientists have created a new type of wiring does not just lightweight and flexible, but also highly conductive enough to replace traditional metal wire in everything from motors and if this techs scales up, it could revolutionise electric vehicles, air space and even everyday Electronics.
The secret is a manufacturing process called liotropic liquid crystal assisted surface texture or last for short. This method takes carbon nano tubes which I already known for their incredible strength and connectivity and solve one of the biggest problem of clumping.
CNT stick together in a messy tangle, which hurts their performance, but with last researchers, used liquid crystals to align neatly while also removing metal impurities leftover from production and hear why that matters. Electric vehicles and aircraft weight is the enemy of efficiency.
Take a Tesla model S, its two motors weigh around 150 pound combined with about 25% of that being copper winding, replace that with carbon two wiring and you could drop the Motor away by roughly 35 pounds that might not sound like a 4500 pound car, but it’s not just about static.
weight less rotating mass means faster acceleration, better throttle response and even gains and range to reduce energy energy loss, but before we get too excited, there are some serious hurdles And still la buying copper 7.7 mega Siemens per meter versus copper is 50 9M Sm in test a CNT based motor maxed out at 3420 rpm while a copper version hit 18 520 rpm, that’s a huge gap.
However, the CNT wire weighed 1/5 as much. so when you factor the performance per pound isn’t as far as it seems then cost CNT wiring currently cost around $375-$500 per kilo kilogram compare to copper. Dirty cheap 10 making CNT energy intensive relies on fossil fuels and generates nasty by products like hydrochloric acid, researchers believe for optimisations like polymer sheets or improve nano tube Could close the conductivity gap even more, and if they can crack high voltage applications, this Tech could spread beyond motors in a full vehicle wiring, harness airspace system, and more for now is a promising glimpse into a light of more official future. One with carbon nano tubes, just untangled the limitations of today’s tech.
