Chinese scientists create energy from lotus leaves, opening door to plant power source

Chinese scientists have created an energy generator that harnesses the transpiration of plants to create electricity, which could transform almost all leaves on Earth into a sustainable and continuous energy source.

The team said its leaf transpiration generator – which they demonstrated using a lotus leaf – was able to power small electronic devices, and could be used to create plant-powered electricity networks.

“This study not only uncovers the unprecedented hydrovoltaic effect of leaf transpiration but also provides a fresh perspective for advancing green energy technologies,” the team wrote in a paper published in peer reviewed journal Nature Water on September 16.

Hydrovoltaic electricity relies on the movement and interaction of water with solid surfaces. Current devices often require a consistent water supply, creating geographic limits as devices must be near bodies of water, such as rivers or dams.
