Dutch Harvest Electricity From Living Plants To Power Streetlights, Wi-Fi & Cell Phones

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.

The company was founded in 2009, and was a spin-off from the department of Environmental Technology of Wageningen University. Again, they develop products in which living plants generate electricity. Their technology allows them to produce electricity from practically every site where plants can grow.

“Via photosynthesis a plant produces organic matter. Part of this organic matter is used for plant-growth, but a large part can’t be used by the plant and is excreted into the soil via the roots. Around the roots naturally occurring micro-organisms break down the organic compounds to gain energy from. In this process, electrons are released as a waste product. By providing an electrode for the micro-organisms to donate their electrons to, the electrons can be harvested as electricity. Research has shown that plant-growth isn’t compromised by harvesting electricity, so plants keep on growing while electricity is concurrently produced.”
