Power my lights for another day.

Researchers in Hong Kong recently developed a droplet-based electricity generator (DEG) that generates electricity from raindrops. 

One droplet can briefly power 100 LED lightbulbs, producing over 140 volts of power.

Don’t go disconnecting from the power grid just yet. 

While this technology is not yet practical for everyday use, it’s an important first step toward a brand new form of renewable energy. 

Keep an eye out for umbrellas that can charge your cellphone. It’s going to be lit (literally).
