(Commonwealth Union)_With the combustion of fossil fuels creating greenhouse gases that are warming the planet, our insatiable energy demand has gotten us into trouble. It is enough to make you envy plants, which use the greenhouse gas carbon dioxide to create their energy by using a process called photosynthesis. We could efficiently liquefy sunlight to produce a clean, green fuel if we could learn to replicate this feat on a large scale.
Unfortunately, photosynthesis is a challenging chemical process to duplicate. It entails several procedures, such as absorbing sunlight, cleaving apart water molecules to make protons, and fusing these protons with carbon atoms from CO2 to create fuel in the form of sugars. Plants produce energy (or fuel) through a process called photosynthesis using water, sunlight, and carbon dioxide.
The goal of a collaboration between Harvard University and Harvard Medical School is to develop a synthetic system that can duplicate this process. This led to the development of a “bionic leaf” that can produce liquid fuels that are high in energy. The proteins that carry out these functions in nature have evolved over hundreds of millions of years, yet they are still only capable of converting sunlight into fuel with an efficiency of 1% at most. Then people began to realize that, rather than reinventing photosynthesis from scratch, we might create a bionic leaf by fusing the greatest elements of chemistry and biology.
These leaves often use substances that effectively absorb sunlight as well as natural proteins that are excellent at joining fuel molecules. The bionic leaf has a lot of potentials. Even though it might not completely replace the enormous pipeline infrastructure that supports our fossil fuel sector, it might be utilized to provide a portable and affordable source of energy in nations without such a developed infrastructure. These artificial leaves may someday be just as abundant as natural ones.
