I was going to suggest this, but take it a step further and consider writing commercially. A huge number of press articles and books have been written just to explain subjects to other who are not professionals in the field, but have an incessant curiosity about many subjects. A casual search will turn up innumerable explanations of how, for example, machine learning works, or what quantum computing could do, what the Mars rovers have found, or what GMO foods are. IMHO, these articles and books provide a meaningful social service in keeping people informed on subjects which could impact society or their lives.
