Tokyo Olympic flame is the first powered by hydrogen
23.07.2021,
TOKYO — Inspired by the sun, the Tokyo Olympic cauldron is designed to be better for the planet.
The flame at Tokyo’s National Stadium and another cauldron burning along the waterfront near Tokyo Bay throughout the games will be sustained in part by hydrogen, the first time the fuel source will be used to power an Olympic fire.
Previous flames have usually run on propane, although magnesium, gunpowder, resin and olive oil have also been used since the first modern cauldron was lit for the Amsterdam Games in 1928. The torch relay was introduced eight years later for Berlin.
