Light Source Operating with Plants was Designed

More than 42 percent of the people living in the rainforests live without electricity. That's why researchers from the Peruvian University of Engineering and Technology (UTEC) have found a way to light homes with the most abundant things in the region: plants and soil.

Engineers utilizing the principles of previous work and the findings of researchers around the world have developed their own clean energy models. Elmer from the UTEC family, explained their system: ”Every plant produces nutrients and these nutrients are oxidized in contact with the organisms called Geobacter and emit free electrons, which are captured with the help of electrodes. Electrodes are located in a grid-like transmission network. The energy obtained to light the lamp can be stored in an ordinary battery."

10 "plant-lambs", the name given to the invention, were given to families living in the rainforest villages of Nuevo Saposoa and Pucallpa in Peru. The villages had power networks but they were damaged by a flood in March. There was no access to electricity since then. The students had to work with kerosene lamps, which not only fills the house with smoke but also damages the eyes and lungs. Mothers also had a hard time taking care of the children after dark.

“We didn't know that a plant could generate electricity for us,” said one of the village residents, and expressed his gratitude "Electricity means life for us and children." Plant-lamb looks like a wooden box with a grid inside and a plant and a rectangular LED electric lamp on it. Researchers hope the invention will benefit even more families in the future.
