Szabolcs commented on Solar assisted manufacturing of ceramic water filters

Hi Chioma, I inluded an extended response above, thank you very much for the question. The most simple device could be a large plastic fresnel lens mounted above the slurry tray that is in the focal plane of the lens. The user can move the slurry tray in 2 dimensions effectively fusing the surface (and baking/sanitizing the bulk if needed) of the slurry point by point creating a filter cartridge disk. I hope it helps, please let me know if you have questions.
