Better Railways.
There are over 30 million commuters in Indian Railway daily.
Why cannot we use this huge crowd to harvest piezoelectric energy?
There are all kinds of situations where we can convert mechanical energy (pressure or movement of some kind) into electrical signals or vice-versa. Often we can do that with a piezoelectric transducer. A transducer is simply a device that converts small amounts of energy from one kind into another (for example, converting light, sound, or mechanical pressure into electrical signals).
