And I Harvest, and I Harvest – Electricity

Plant-e generates electricity from living plants

Just imagine, a house with a roof full of plant/tree life powering your home. On the company’s website, they feature animated pictures of mini-forests growing on building rooftops supplying power to the entire building.
Plant-e, a company based out of the Netherlands, has found a way to harness electricity from living plants, using them to power Wi-Fi hotspots, cell phone chargers, and even streetlights.

The company debuted their project, called “Starry Sky,” in November of 2014 near Amsterdam, where they lit up more than 300 LED streetlights at two different sites. Their plant power technology is also being used to power the company’s headquarters in Wageningen.


How does that work?
Plants photosynthesize organic matter using solar energy. A significant part of this organic matter is released into the soil. There electrochemically active micro-organisms break down the organic matter producing electrons which are transported to the anode of the fuel cell. The energy rich electrons flow through a load to the cathode to generate 24 hours per day electricity.
