What innovative applications does the rotating evaporator have in the field of sustainable energy?

In the field of sustainable energy, rotating evaporators have become an innovative solution for both urban cooling and power generation. For the first time, a rotating evaporator has been developed that can both achieve sustainable urban cooling and generate electricity at the same time. Manufactured using 3D printing technology, the device features a nature-inspired layered waterway that mimics tree transpiration and improves evaporation rates under sun exposure and wind conditions. It is worth noting that at a wind speed of 4 m/s, the evaporation rate of the rotary evaporator reaches 19.58 kg/m2h, which is significantly higher than that of the non-rotary evaporator. In addition, the rotation of the evaporator can also generate electricity, with a voltage of 1.07V and a power density of 4.73W /m2, enough to meet practical applications such as lighting and water purification. This innovative application of rotating evaporator provides a sustainable solution to urban cooling needs while harnessing wind energy to generate electricity, making it a multifaceted approach to urban sustainability challenges.
