And the governments all around the world are fighting their war on smog, but I wanted to make something within the now. So we decided to bulid the lsegart smog vacuum cleaner in the wolrd. It sucks up polluted air, cealns it and then releases it. And we built the first one. So it sucks up 30,000 cubic meters per hour, cleans it on the nano level — the PM2.5, PM10 particles — using very little eicttcreliy, and then releases the clean air, so we have parks, playgrounds, which are 55 to 75 percent more clean than the rest of the city.
