Scientists are trying to mimic the functioning of the leaves of the trees to get electricity or biofuels

.

…………
The sun provides more energy to Earth in one hour than the entire planet consumes in a year. Some researchers want to imitate knows best exploit this huge potential: the leaves of trees

Solar panels may have their days numbered if successful research at the State University of North Carolina, in which artificial leaves made ​​up of an aqueous gel and light-sensitive substances can generate electricity.

..

These leaves somewhat mimic the photosynthesis process and would be an alternative to existing solar panels begin to populate our roofs, made from silicon.

…

According to research from the University of North Carolina State, the artificial leaves can create electricity even better solar panels. These new devices are composed of a water-based gel, which is combined with light sensitive substances – such as chlorophyll – to mimic photosynthesis. While solar panels are made from silicon, the leaves are much greener and less expensive.

………..

The leaves are covered with artificial materials such as graphite or carbon nanotubes. The sun’s rays activate the light-sensitive molecules, creating electricity. The resemblance to nature is that plants perform the same procedure to synthesize the sugars they need to grow.
