Take some carbon dioxide and throw in a little water. Add sunlight and chlorophyll. What do you get? Oxygen, sugar… and the key to life on Earth. Photosynthesis is the plant superpower, and this ability to convert light energy – the most abundant energy source on Earth – into chemicals is what keeps us humans alive. But what if we could develop a hack that allows us to siphon off some energy from this process? Are clean energy systems that rewire photosynthesis actually such an improbable idea?
