The living wall of the Cambridge Botanical gardens P2P hub which is being used to trial Plant-BES (a plant bio electrochemical system) to generate a carbon neutral source of electrical current.
Plants harness solar power to produce organic compounds through photosynthesis. Bacteria that live symbiotically in plants' root systems feed on and oxidise the by-products of photosynthesis and release electrons and protons into the soil. The electrons are collected by an anode, the photons by a cathode. The electrons and photons are recombined by being passed through an external circuit which generates the current.
The P2P hub uses Pant-BES in combination with aSi-PV solar panels to harvest solar power to eventually be employed as a technology in building self-powered buildings and structures. Here is a link to further information about the project and a link to the logs of the output generated by the P2P so far.
Clicking through the University of Cambridge, Plant Sciences web pages we discovered a link to video demonstration of a moss "fuel cell" powered radio. Clever stuff.We ♥ living walls.
A-tishOOoo - more than enough forage to meet nectar responsibilities here.
