Raindrop: A new technique to generate electricity?



Hydropower is derived not only from the energy of running water, it can also be converted from kinetic energy generated by waves, tides, and even raindrops. Scientists in Hong Kong have developed a droplet-based electricity generator which can light up 100 small LED light bulbs by a drop of water. Can droplet energy be widely adopted in Hong Kong?
