Plants can generate sustainable energy as they grow

A Dutch start-up, Plant-and developed a way to use the plants as a continual source of clean energy â€" you only need a light source, carbon dioxide, water and plants.

When plants create their own food through photosynthesis, much of the organic matter generated is excreted into the soil through the roots. This matter is consumed by microorganisms that live in the soil. In turn, these microorganisms release electrons, as byproduct of this consumption. This start-up system consists of placing an electrode near the root system of the plants, which stores this wasted energy and converts it into electricity, referred to Inhabitat.

The process is similar to simple school experiences made with electricity, using apples or potatoes to create batteries. However, this system has the advantage of not harming plants, which continue to grow normally even in the presence of the electrodes, and can be, in this way, a constant source of energy, both day and night.

The system works best in damp or flooded land, as the rice fields, and it doesn't matter if the water use is polluted or has already been used. This factor allows improper areas to cultivation can be reused as an energy source. The system does not require the installation of elaborate infrastructure, which can allow carry electricity to isolated regions that are not served by mains.

Is already being tested in the Netherlands a prototype green roof that uses this technology. Currently, the Plant-and can produce enough energy to power a mobile phone, but the aim is that this method be used soon to collect a larger amount of energy â€" enough to power a home.
