Wow, I am just blown away by the submissions to Google’s Science fair. It’s for youth 13 and 18 to come up with their own science or engineering project and share their findings. I was particularly moved by our Canadian talking about filtering oil sand tailings using bacterial and the Russian about a more efficient ultrasonic fuel injector.
Canada’s Hayley Todesco (who is 17 I might add) says “I found I could break down these acids to the point where I could probably reduce the detoxification of these tailings ponds from centuries to decades”.
You should really have a look and vote.
