In recent years, global warming has been progressing, and there are calls for reduction of carbon dioxide emissions and sustainable energy use. In particular, carbon dioxide emissions from fossil fuels are on the rise, and there is an urgent need to promote the use of alternative energy sources. This experiment aims to distill water using solar heat to produce fresh water for domestic use and irrigation. Sunlight is concentrated using a Fresnel lens, and the concentrated light is directed onto a metal plate, which is then placed in water for distillation. The objective is to efficiently generate fresh water while increasing the light collection effect.
