Folding@Home may have found the path for a therapeutic that could be effective not just against SARS-CoV-2, but all known coronaviruses. Of course, always good to pursue multiple approaches (DreamLab, etc.) in case one path doesn't pan out.
I could be wrong but I believe there is already an Android Folding@home client.
Edit: Ok, found it. https://play.google.com/store/apps/details?id=com.neocortix.pocketscience - Not exactly official but I believe it works.
