When the Tokyo Paralympic Games came to a close on Sunday, many athletes had managed to get to the finish line, some with medals, thanks to technology from Japan¡¯s largest firms.
Honda Motor Co.¡¯s latest model of racing wheelchair, for example, features carbon technology that¡¯s also used for the company¡¯s F1 racers and jet planes. Using carbon in its key components, including the frame and wheel, the vehicles weigh just 7.9 kilograms (17.4 pounds), among the lightest in the industry.
