Throughout the years, the global energy crisis has been a concern due to how much it impacts different sectors of the globe. Limited natural resources used to power industrial society are slowly diminishing as they cannot keep up with the world’s demands. Despite rapid urbanization in the country, various rural areas still do not possess access to electricity because they cannot afford them. Aside from the lack of accessibility, power generation has also relied on fossil sources such as coal, oil, gas, diesel, and - though increasing - lacking in terms of renewable energy.

Though issues in electrification rates in Indonesia is not as prominent as it was before, it is still on the loom for many. We can use the numerous advancements in the world's technology to our advantage to increase these electrification rates and simultaneously utilize alternative energy that is green and renewable. One of the advancements we can eye is piezoelectricity, the electrical charge that accumulates in certain solid materials in response to extrinsic mechanical stress.

My goal is to assemble a product that may potentially make an affordable and easy alternative energy to the households of rural areas, developed using newly learned technical skills. With the words piezoelectricity, sounds, and light scattered throughout my mind like the remains of the titanic, observing possible solutions has led me to the final product of a flashlight harnessing vibrational waves into usable electricity. The product will be experimental and relies on trial and error. The wave I chose to harness for this project is sound which will then be translated into usable electricity by a piezoelectric disc and a series of electric components.
