Pete, a maidenhair fern who lives at ZSL London Zoo, is preparing to take the world’s first plant selfie. Under the pioneering project taking place in the zoo’s Rainforest Life exhibit, microbial fuel cells – which harness the energy of naturally occurring bacteria in soil to generate electricity – will be used to power the plant to take its own picture. The fuel cells were designed by green energy specialists Plant E in the Netherlands and were created after ZSL’s Conservation Tech Unit, in partnership with Open Plant, Cambridge University and the Arribada Initiative, last year launched a competition to design a fuel cell that could be powered by plants. The new technology, which works around the clock, has the potential to allow researchers to monitor inhospitable and remote rainforest locations and record key data such as temperature, humidity, plant growth – all of which are crucial to the understanding of threats such as climate change and habitat loss. Zoo staff are asking people and come and cheer Pete on as he prepares to take his selfie with the actual event not expected for a few weeks. For more, see zsl.org. PICTURES: © ZSL London Zoo.
