Electricity from living plants. Dr. Marjolein Helder, Plant-e, Web Summit


So this is our newest product. We
produce electricity with living plants What we do here is we actually
generate electricity with the plants that grow here, and we gather
technology in the box. And then we can light the LEDs that are on top of this box so if I push this button then all these glass fibers turn on and off randomly as a light effect. This technology’s completely safe for the
environment. We actually make use of natural processes around the plant, and
we don’t do anything to change that so what we do is the plant produces
organic matter and releases some of it into the ground and then bacteria in the
soil break down the organic matter and they release electrons. So we capture the
waste products from the bacteria so the electrons and use them as electricity
and that’s it. Basically this is what’s in our boxes, and what we could put into full ground as well so this is the simple system with two electrodes. An anode and a cathode where we can actually capture the electrons and produce electricity. So basically it’s sort of a battery but then with very sustainable materials and running on biological processes. Today you we can light a few LEDs or you could charge your cell phone on probably 15 to 30
square meters, so that’s a large phone charger but in the future we’re looking to produce more power and at the lower cost price so that we can generate
enough power for several households on a hectare
