For the past two centuries, humans have relied on fossil fuels for concentrated energy; hundreds of millions of years of photosynthesis packed into a convenient, energy-dense substance. But that supply is finite, and fossil fuel consumption has a tremendous negative impact on Earth's climate.
One possible option that scientists are exploring is "artificial photosynthesis" - reworking a plant's system to produce our own types of fuels. However, the chemical equipment on a single sheet is incredibly complex and not so easy to use for our own purposes.
