Artificial photosynthesis machine improves itself over time.

Most of these devices lose efficiency the longer they work. This one gains it.
Plants are living things, and like all living things, they need energy to grow, reproduce, and just keep on living.
Most harvest this fuel through photosynthesis, using solar energy to convert water and carbon dioxide into chemical energy useful for life.
Now, researchers are homing in on an artificial photosynthesis device that could let us do the same trick, turning sunlight and water into clean-burning hydrogen fuel for our cars, homes, and more.
Solar cells already let us convert sunlight into electricity. Artificial photosynthesis devices, however, use sunlight to turn water or carbon dioxide into liquid fuels, such as hydrogen or ethanol.
These can be stored more easily than electricity and used in different ways, allowing them to substitute
