Scientists develop 'tiny wind turbine' to scavenge energy from gentle breeze – video report

Scientists have developed a 'tiny wind turbine' that can take energy from a gentle breeze, such as that made as you walk.

The device comprises two plastic strips in a tube that flutter or clap together in the presence of airflow. That energy, powered by the contact and separation of two materials, can be bottled up and stored for use, according to researchers.

Scientists in China hope the device can generate sustainable power in a low-cost, efficient manner while 'overcoming the issues that the traditional wind turbines can't solve'
