Every year, billions of vehicles worldwide shed an estimated 6 million tons of tire fragments. These tiny flakes of plastic, generated by the wear and tear of normal driving, eventually accumulate in the soil, in rivers and lakes, and even in our food. Researchers in South China recently found tire-derived chemicals in most human urine samples.
Does anyone know of another efficient mode of transportation that has near-zero surface friction?
Because that would be a gamechanger
There are some vehicles that go on iron wheels, on a special kind of iron road that are very efficient. Only bad parts are costly initial investment and difficulties to scale up if the existing network gets overloaded (such as the Swedish rail system who has been over “maximum” capacity for a long time which has put needed maintenance on hold at many places)
Maglev?
Hyperloop theoretically, practically who knows.
Maybe there’s some kind of a wheel, like a metal wheel that could just glide across narrow metal surfaces that could follow a set path….
Well the was this idea of propelling trains through a vacuum tube system.
Unfortunately it’s being developed by a shithead and misappropriated by the car industry to hamper railway development in the us
