Micheál O’ Halloran is a mechanical engineer. He came into our classroom and spoke to us about the engineering that is involved in things like Avatar and Grey’s Anatomy.
He told us all about the different engineers that are involved in making a rollercoaster.
He explained to us how a Pelamis works. We learned that there is a motor and a generator inside it. He told us that the movement of the waves cause pistons move in and out, which in turn causes the motor to turn and the generator to work.
He told us that if you want to be an engineer you have to enjoy doing Maths.
