ScienceDaily (Nov. 6, 2009) — Scientists are making progress toward development of an "artificial leaf" that mimics a real leaf's chemical magic with photosynthesis -- but instead converts sunlight and water into a liquid fuel such as methanol for cars and trucks. That is among the conclusions in a newly-available report from top authorities on solar energy who met at the 1st Annual Chemical Sciences and Society Symposium.
"The sun provides more energy to the Earth in an hour than the world consumes in a year," the report states. "Compare that single hour to the one million years required for the Earth to accumulate the same amount of energy in the form of fossil fuels. Fossil fuels are not a sustainable resource, and we must break our dependence on them. Solar power is among the most promising alternatives."
The symposium focused on four main topics:
Mimicking photosynthesis using synthetic materials such as the "artificial leaf"
Production and use of biofuels as a form of stored solar energy
Developing innovative, more efficient solar cells
Storage and distribution of solar energy
