Photosynthesis is the primary form of energy production for plants. The energy produced and stored in their molecules is their main source for their food. Many scientists therefore are working on finding a way to mimic their mechanism, focusing mainly on the part which comes after the production of energy, in a way to store it and keep it for future use or even distribute it directly for the needs of the society.
This is in short our inspiration by plants, production and storage of energy which either comes from the sun, either the wind or even the rain.
