The team of researchers at MIT in the U.S. has discovered a more effective way to produce sustainable energy. The manmade device simply called the ‘artificial leaf” is ten times more efficient and powerful than a natural leaf when it comes to photosynthesis. The artificial leaf is no bigger than a typical playing card and is powered by solar-like cells. Once immersed in water and exposed to sunlight, the leaf begins to bubble and separate hydrogen and oxygen. The oxygen and hydrogen can be captured and stored to produce electricity.

MIT professor, Daniel Nocera. explains that artificial leaf is inexpensive to make, using common materials like silicon, cobalt and nickel. Nocera hopes that the concept can help developing countries:

Our goal is to make each home its own power station. One can envision villages in India and Africa not long from now purchasing an affordable basic power system-based on this technology.
