System created that can produce electricity for 100 LED bulbs from a raindrop

Researchers have made a transistor-style generator that can produce high voltage from raindrops. The generator can produce 140V or enough to light up 100 LED bulbs from a single drop. The researchers made an aluminum electrode using indium tin oxide electrode and layered it with a "quasi-permanent" electric charge which created a closed-loop circuit, that produces electricity as its rains.
