Plant Powered Lamps Light Up Peruvian VillagesPeru is a developing country in Latin America. It has one of the region’s best economies with a 50% growth in per capita income in a decade. Despite the country’s growing success, there is a considerable gap in electricity access between rural and urban parts of the city. Only about 62% of people in rural areas have access to electricity. Fortunately, a group of students and professors from a Peruvian university are developing a solution to combat the issue. The plantalámpara is a lamp powered solely by plants that will light up Peruvian villages.

How Did the Idea Come About?

A hurricane occurred in the Amazon rainforest area of Peru that left 173 inhabitants of the Nuevo Saposoa region without electricity. Also, about 42% of the rural population did not have electricity at all. The Nuevo Saposoa village is remote and isolated from nearby cities. It is a five-hour boat ride from the nearest town, so the village could not receive reliable access to electricity after floods from the hurricane destroyed power lines.

Consequently, the inhabitants could not perform daily tasks after sunset, like studying and cooking. A professor and group of students at the UTEC University in Lima developed the plantalámpara to solve the issue of the lack of electricity. The plantalámpara lights up Peruvian villages. The developers encourage people to get back to their normal lives.

The plantalámpara is made in a box filled with a grid of electrodes and a plant growing inside. Photosynthesis, or the capturing of sunlight energy by plants, powers the box. When the plant goes through photosynthesis, its waste decomposes in the soul and produces electrons. As a result, the lamp captures those electrons and converts the energy into battery power. It can light up a 50-watt bulb for up to two hours.

Benefits of the Plantalámpara

The lamp provides clean and sustainable energy to forest villages without using gas, oil, or dirty fossil fuels. The plant-based light is entirely pollution-free. Additionally, plants offer 100% renewable energy at a low cost. According to a lead professor of the project, any plant can be used for the lamp, though some work better than others. The plantalámpara protects the beautiful rainforest, lights up Peruvian villages, and provides the Nuevo Saposoa community with more opportunities and a better quality of life.

It also gives Peruvian residents the possibility to work on schoolwork and other tasks past sunset. UTEC intended to put the digital community in the shoes (or eyes) of a forest dweller to understand how a lack of light can affect daily actions. The team originally provided 10 of the lamp prototypes to Nuevo Saposoa. The hope is that these lamps will eventually replace gas and oil lamps.

The plantalámpara serves as a crucial part of reducing the gap between rural and urban areas of Peru. Its amazing eco-friendly technology helps to light up Peruvian villages while not harming the environment at the same time. With this invention and more, Peru will continue to grow and expand, as more opportunities become available to all.
