Could We Get Clean Energy From Artificial Leaves?

Could We Get Clean Energy From Artificial Leaves?

Harvard chemist Daniel Nocera developed an artificial leaf that can generate clean energy, and he hopes to improve the design so much so that it can cheaply and efficiently power homes. The leaf produces hydrogen and oxygen wirelessly. When submerged in water and exposed to light, catalysts on either side of the strip break down the water molecules into their basic components. Right now, the leaf requires someone to use a fuel cell in order to convert the hydrogen it produces into electricity. We've collected some awesome videos on this topic.

Key Facts In This Video

  • 1

    The artificial leaf splits water molecules into oxygen and hydrogen, the latter of which can be used for fuel. (1:10)

  • 2

    The artificial leaf design doesn't rely on rare, expensive metals, but rather on readily available materials. (2:47)

  • 3

    Hydrogen produced by the artificial leaf needs to be captured and stored for use in a fuel cell that generates electricity. (4:32)
