Stimulated by a real-world problem, the shortage of electric energy in remote areas of Peru and particularly in rural areas of the tropical forest, the University of Engineering and Technology (UTEC) in Peru, through a team of researchers - made up of teachers and eight students – developed a Plant lamp, an innovative alternative renewable energy generating system.
The Plant lamp developed by UTEC is capable of supplying two hours of light per day through a low energy consumption, high illumination LED lamp. The system operates with the energy stored in the soil containing nutrients and/or microorganisms released by plants during their growth and this enables us to use the free electrons from the microorganisms and in this way feed the lamp.
“We put the plant and soil into a wooden plant pot together with a previously established and properly protected irrigation system. Then, inside the pot we place the energy generation system that we created which stores soil and electrodes capable of converting plant nutrients into electric energy” explains Elmer Ramirez, a professor of Energy and Power Engineering at UTEC and leader of the Plant lamp research team.
