What is this engineering task?

: During this Science-Engineer¬†Project, students are designing a device that converts energy, taking a renewable energy & converting it to electrical energy, and creating a device that can be used to teach. The point is that we need to express our understanding of energy transfer. ‘Engineer’ means any engagement in a systematic practice of design to achieve solutions to particular human problems, and we are using our scientific ideas on designing and creating.

What are you thinking about doing?

: I am planning to create a device that transfers either sound, thermal, pressure force, to electric energy and make the light bull works. However, I am sure that I am not going to waste the electric energy to make the electric energy. I hope I can create the new energy transfer techniques.

The advantage of my idea would be saving the energy, but it will be hard to make a successful design.
