Harnessing plant power (Image: Pasieka/SPL)From New Scientist:
HIDDEN detail in the natural world could hold the key to future sources of clean energy. So say materials scientists who have created an artificial leaf that can harness light to split water and generate hydrogen.
Plant leaves have evolved over millions of years to catch the energy in the sun's rays very efficiently. They use the energy to produce food, and the central step in the process involves splitting water molecules and creating hydrogen ions.
