A torch of technology without a flame illuminates China's 15th National Games

00:16

The opening ceremony of China's 15th National Games on Sunday featured a 'torch of technology,' marking the event's first-ever main cauldron that is not based on fire.

Upholding a low-carbon approach, the cauldron was powered by green electricity generated from advanced photovoltaic systems, combined with precise mist and lighting control that realistically mimicked the flicker, brightness, and movement of a real flame.
