## Transcript

[ MUSIC ] The toilet industry, let's say. The sanitation industry has not changed through the hundreds of years and that has been a big issue. The hazard that comes from poor sanitation is almost equivalent to the hazard coming from malaria and AIDS. Right now, 2. 6 billion people in the world don't have access to healthy sanitation. [ MUSIC ] Our design had three important properties that is really unique. And first is disinfection. We can disinfect the human waste based on electrochemical degradation. So after few, for example, ours, we don't have any kind of infection remains. But then, there's off the grid operation.

We see that there are a lot of places in the Africa or South Eastern Asia, and also some remote places in the US that they don't have access to good power source which we pull right from the sun and its enough for our treatment. And the third one is, it doesn't have pollutant. And it's also has green byproduct like Hydrogen, which is like oil, can be used as a source of energy.
