Japanese researchers and auto parts manufacturers say that a material made of wood pulp weighs only one-fifth of steel and is five times stronger than steel.
They say that this material-cellulose nanofibers-may become a viable alternative to steel in the next few decades, although it faces competition from carbon-based materials, and it is still a long way from commercialization. The way to go.
As manufacturers push electric vehicles to the mainstream, reducing the weight of vehicles will be crucial. The battery is an expensive but vital component, so the reduction in the weight of the car means the reduction of the battery required by the car, thereby saving costs.
