About 400 million years ago, as a historic event, evolution created plants with green leaves that carried on a groundbreaking process called photosynthesis. It used sunlight as the source of energy to convert carbon dioxide from the air and water, provided by the roots from the soil, to generate oxygen and sugar (carbohydrates) to shape the earth’s environment for the complex organisms to evolve and survive. Of course, prior to it, some algae and bacteria were carrying on the process, but it turned revolutionary after the appearance of the green leaves. It still continues to be the most essential life-sustaining process, serving as the primary provider of clean, oxygen-rich air to breathe, food to eat, and pure water to drink, without which life on the surface of the earth could have been doomed.

At present, one of the most serious problems that mankind is encountering, which is increasing with time, is the growing energy needs. On the other hand, the sources of fossil fuels are fast depleting, and the extensive use of those has also become a root cause of environmental pollution, the most devastating consequence of which is global warming.  Therefore, all our efforts are now underway to develop dependable and clean renewable sources of energy…read more NOPR
