Artificial Photosynthesis - JCAP center
Simulating nature's photosynthetic apparatus
for practical energy production.
The Joint Center for Artificial Photosynthesis (JCAP), to be led by the California Institute of Technology in partnership with the Lawrence Berkeley National Laboratory, will bring together leading researchers in an ambitious effort aimed at simulating nature's photosynthetic apparatus for practical energy production.
Integrated solar energy-to-chemical fuel conversion system
The goal of the Hub is to develop an integrated solar energy-to-chemical fuel conversion system and move this system from the bench-top discovery phase to a scale where it can be commercialized.
Sunlight, water, and carbon dioxide
"Finding a cost-effective way to produce fuels as plants do -- combining sunlight, water, and carbon dioxide -- would be a game changer, reducing
our dependence on oil and enhancing energy security."

Natural Photosynthesis - plants
"We're not talking about solar panels,"
but HOW TO
Convert solar energy directly into fuels like methanol, ethanol, gasoline (chemical)
said Peidong Yang, a professor of chemistry at UC Berkeley who heads the Bay Area branch of the project. "We are going to develop technology to convert solar energy directly into chemical fuels like methanol, ethanol or just gasoline, through carbon reduction."
Center for Artificial Photosynthesis
"Fuels from Sunlight Energy Innovation Hub."
Scientists from UC Berkeley, Stanford University and the California Institute of Technology have been given $122 million to come up with ways to produce fuels directly from sunlight.
The U.S. Department of Energy announced the grant Thursday to a team led by Caltech in Pasadena, also includiing Lawrence Berkeley National Laboratory, UC Berkeley and Stanford. The team's mission: Develop practical methods of manufacturing "carbon neutral" fuels similar to the way plants create energy via photosynthesi
Goal: Solar fuels generator better than crops
that, without the use of rare materials or wires, robustly produces fuel from the sun 10 times more efficiently than current crops"
Chlorophyll is a green pigment found in plants.
It is often described
as the ‘green blood of plants’ due to the fact that it is very similar in chemical structure to the Haemoglobin that is found in human blood.
It is chlorophyll that converts the energy from the sun into fuel that the plant can store and use to grow by a process known as photo-synthesis. In addition - chlorophyll is also a natural detoxifier and a potent antioxidant.
