Electrical energy generation from

Raindrops

Sunshine, wind and vast amounts of water or

hydropower, solar and wind energy aren’t the

only saddle to ride for electricity generation.

Solar panels are essentially useless in the rain.

But if raindrops themselves could fall on a solar

panel and generate electricity that would be
riveting.

However, there's not that much power there to

harvest.

The best the hypothetical device could do is to

transform all the energy due to the

motion of a falling raindrop into electricity. That
kinetic energy is usually computed by

multiplying one-half the mass (m) of the moving

object by its velocity (v), and then

multiplied by the velocity once more, and is
usually written as follows:
