Eighty years later, the Swedish Consortium for Artificial Photosynthesis was established to work on the problem in earnest. Since then, artificial photosynthesis has been a major area of research all around the globe. The tricky things are making it efficient at the relatively low concentrations of carbon dioxide in the atmosphere and turning the lab-based science into a working technology!
