Developing a re-invented toilet has been both challenging and exciting. It is one thing to
prove a concept in an academic laboratory; it is much harder to get a prototype built and
developed to the point where it can be used in a household – by household members ranging
from the 5-year-old child to the 80-year-old grandmother. Transformative innovation does
not happen linearly; we have made detours, gone down dead ends, and circled back to
approaches we have tried before. We have solved thousands of problems big and small, and
the exciting thing is that we can see the light at the end of the tunnel. We feel
privileged to be part of a dedicated community working hard to address a tremendously
important problem for the world’s most vulnerable population.
