China high school students use a draughty staircase to charge portable battery
Two creative high school students decided to use the wind in a draughty staircase to charge a power bank.
In the video, filmed in Yangjiang City in southern Guangdong Province on September 16, a student holds a fan out into the staircase with the draught turning the blades.
Another student attached the fan’s plug to a portable charger’s plug. The charging signal light on the portable charger is then seen flashing and powering up.
