Light generated from plants
The delightfully named Plantalámpara — or plant lamp – is a low-cost LED lamp that uses plants and soil as its batteries.
Inspired by real and immediate problems in remote areas of the country, researchers at Peru’s Universidad de Ingeniería y Tecnología (UTEC) have developed this remarkable piece of technology which actually draws its power from the microorganisms in the soil that are released by plants as they grow.
