At the Geneva Motor Show, Goodyear Tire and Rubber Company
presented the concept of automobile tires that are able to generate electricity due to the heat generated from friction while driving. The generated electricity is proposed to be used to save energy and power the batteries. The range of movement on a single charge in modern electric cars is not so high, and various solutions are being developed to increase it. The concept of BHO3 tries to solve the same problem by using electrical elements.
While driving, the tires experience deformation and heat up. The tire material BHO3 absorbs this heat and converts it into electrical energy. This is all the information provided on piezo and thermoelectrics in the concept; in general, Goodyear does not go into great detail when describing the structure. It also did not indicate how much energy can be obtained in this way. It is likely that the amount of energy produced is too small to play any role, but the company is optimistic about the possible relevance of technology in connection with the future distribution of electric vehicles.
Another new product from Goodyear at the auto show was the concept of tires with three cameras located in a row from the inside to the outside of the tire tread. Air moves from the main chamber with an integrated pump to create three different configurations: eco-friendly, sports and for wet surfaces. Like BHO3, this is still only a concept.
