Plants and algae use photosynthesis to produce their own food. They use light energy from sunlight converted to chemical energy to help turn carbon dioxide and water into a food source. The waste product of that process being oxygen.

Panasonic has been working to recreate that process in the lab, and has now managed to develop an artificial photosynthesis process as efficient as the one used by real plants. p>

Panasonic's system takes on carbon dioxide, but instead of producing oxygen it generates formic acid, which is useful for creating dyes and fragrances, producing cleaning products, and is used to preserve livestock feed and ant stings).

This formic acid production is made possible through a combination of a nitride semiconductor and metal catalyst where the reaction occurs. The efficiency rating is 0.2%, the same as real plants, and much higher than the 0.04% previous solutions were able to achieve.

It is hoped that the artificial photosynthesis system can be used to cut down on carbon emissions at source, such as near incinerators or other industrial sites where carbon dioxide is produced. And it's totally artificial, it should not require the same care and attention real plants need to survive.

Panasonic holds a total of 29 patents relating to the development of this artificial photosynthesis system.
