Performance of a piezoelectric energy harvester in actual rain
It is described using added mass coefficient in this study. In an actual rain experiment, a piezoelectric beam with surface area of 0.0018 m 2 is able to produce 2076 μJ of energy over a duration of 301 min. The energy generation of a raindrop impact piezoelectric energy harvester is highly dependent on the rain rate.

Moreover, there is a better non-linear relationship (R 2 = 0.807) between average rainfall Ek and sediment discharge ( Table 2 and Figure 8 A ). Rainfall not only creates surface runoff to transport sediment, but rainfall energy also impacts the surface to produce more detached debris particles. Table 2.
Hydrogen Energy Storage | IEEE Climate Change
Hydrogen has been studied for years as an energy-storage medium. Indeed, hydrogen fuel cells are used today to power vehicles, with the byproduct being plain water. To date, generating any hydrogen other than grey, brown, or black hydrogen has been prohibitively expensive and difficult to produce, which is why currently about 95% of hydrogen is ...

Electric raindrops? New solar cell design harvests energy from rain
But now a team of Chinese researchers have created a solar cell that harvests energy from raindrops. The hybrid device works by collecting spare electrons from falling droplets of water so it derives solar energy AND rain energy. It does this by utilising the triboelectric effect: the creation of electric charge as water or air disturbs a surface.
