In the search for source of green electricity there are two main questions: how electricity is produced in nature and which organism could lead the production while the process has advantage for itself and for the other beings?
Ecology give the answer: plants.
Photosynthesis is a process by which plants use light to produce the nutrients they need to survive, besides to release oxygen.
A plant produces more organic matter than the required for the own sustainability and growth, the excess is expelled through the roots into the soil, where bacterias break down the organic matter into water and CO2.
During the process of break down electrons are produced - as kind of waste - and can be harvest.
The electricity produced it depends on the quantity and kind of plants.
This production of electricity is called Plant Microbial Fuel Cell ( Plant-MFC ) and according to Plant-e, spin-off company of Wageningen University ( Netherlands ) created in 2009, can be implemented in disparate places both urban ( for instance green roof ) and country side such as for instance rice field where would be possible produce food and electricity at the same time.
Off-grid IoT devices and transmitters can be powered without need of solar panel.
