Several molecular systems have been constructed that mimic various aspects of photosynthesis. Two of these utilize molecular systems that are derived from natural photosynthesis but that incorporate chemically based modifications to produce artificial photosynthetic devices. These devices use artificial photosynthetic pigments to drive chemical reactions across lipid bilayers or use noble metal catalysts to change the function of the photosynthetic process to produce hydrogen and oxygen instead of sugars ethanol and oxygen. Neither of these systems are sufficiently robust to be operated for extended periods of time as energy unit conversion devices, but they have shown that it is possible to produce artificial photosynthetic assemblies that function well in a laboratory setting.

Nowadays, solar power have become more affordable. That makes it a viable alternative energy option for homeowners who would like to save their electric bills each month and for the environmentally conscious who would like to take the financial benefit. Actually, the advantages of energy from the sun focus on global warming and independence from fossil fuels. (more…)
