Solar energy is clean and limitless, and the operational costs are close to nothing once you’ve installed a solar panel as no fuel is needed to create a considerable amount of energy. And a single kerosene wick burns an estimated 80 liters of fuel, producing more than 250 kilograms of carbon dioxide per year.
To help people living in remote places with limited access to electricity, we made a low-cost solar light bulb as a replacement for a harmful kerosene lamp.
I have already posted an Instructable on this project. The earlier version is quite popular on the internet and useful for people all around the globe. So, I thought to redesign the lamp.
