In the domain of electric motorcar , efficiency is king — wasted energy is just more Swedish mile you ca n’t travel . While regenerative braking is onetime news , regenerative tire that practice high temperature and vibration to reload the bombardment would be something completely raw .
That ’s the construct that Goodyear introduced at the Geneva Auto Show this week . The tyre — which are very much still a construct , and scarce a twinkle in the manufacturer ’s eye — would glean high temperature from several different cognitive operation , and then give that back into the batteries .
At the core of the concept is a stratum of piezoelectric material underneath the rubber eraser of the tyre . Piezoelectric materials can yield electrical energy from the covering of mechanical force , but in this instance , the ( non - specified ) ‘ thermo - piezoelectric ’ fabric ingest excess heat from the outside of the tire and change over it into electricity .
The heat comes from the friction of the tire on the road , the sunlight acting on the tyre , or even just the vibration and bumps of driving along the road . It ’s unreadable how much electrical energy these wizardly tires would be able-bodied to revitalize , or how much the techno - magic tire would end up cost . But at least it ’s novel to do it that the tire companies are still think way , way outside their rubber - line boxwood . [ Goodyear ]
