Scientists at the Massachusetts Institute of Technology (MIT) have what could be a breakthrough in providing , alternative energy. Researchers have invented an artificial leaf that water into hydrogen and oxygen and stores the energy in a cell. The device is about the size and shape of a playing , but is even thinner. It is from silicon and electronic components. The MIT team says it could a home in a developing country for a whole day just by putting it into water under the sun. The artificial leaf is also cheap to . Research team leader Daniel Nocera said a prototype of his leaf in his laboratory operated -stop for over 45 hours with no in activity.

Technology that can efficiently sunlight and water into energy has long been as the Holy Grail of science. The conversion of energy into hydrogen is one of the answers to the question of how to an effective alternative to fossil and thus end our dependence on oil. Nocera’s invention could even help save the , by turning around global warming. Furthermore, in light of the at Fukushima, Japan, it might also prove to be a replacement for nuclear energy. However, this is all thinking at the moment. The technology, although highly promising, is still in its early stages of development. In the near future, it could provide energy to people in areas of sunnier countries.
