At the start of the second week, students have been asking the engineers some pretty challenging questions.

In Transport Zone student neilaandkitty asked Emma “Are you not a pacifist? Did you want to be responsible for machinery that could effectively end lives?” Emma defends her work as a weapons engineer as a means of defending our life style, peace and retaining the free country we live in.

In Health Zone Paige fills in student jonese on the health risks of using nano technology to treat diseases, with a video of a man who has literally turned Blue from drinking silver nano particles!

And Martin discusses with student deviesl3 the possibility of inventing a moon lift.

It’s great to see topical issues like these being discussed in both questions and live chats.
