Profession: Educator

Inspired by: Got to know there was a big aviation accident in the past due to A/C explosion and there had been many studies on how to prevent it. I used to work with students on solar aeration for polluted water recovery in lakes and rivers. To do experiments we needed to degassing for repeated testing. At the beginning we used nitrogen, but later on we got to know that by vacuuming the tank bubbling was a lot easier.
