Chinese scientists develop 3D conic device to increase solar-thermal conversion
The device, named artificial transpiration by Zhu Jia and his team from Nanjing University, is inspired by the transpiration processes of trees
It has a special 1D water path within it, which can reduce the energy loss in conduction,
The cone structure, based on graphene oxide film, can collect more sunlight throughout the day compared with a flat device
As a result, the device can enhance the solar-thermal conversion rate to 85 percent, much higher than the 40 percent of common devices,
this structure was first applied to solar waste-water treatment, and the test showed that it could not only retrieve clean water but also recycle heavy metals such as copper and cadmium.
