Artist Lecture: Miguel Palma's Q's

Q #1: Using many different vehicles and technology, is it hard to master and understand the machines you create/use? Is part of the art in the making of this device? (Palma has made many different cars, planes and other machines)
Palma describes that when he goes into making most projects it isn't just by himself. He has a team of other people helping him. He didn't say this outwardly for his vehicles that he created but for other works so I'm assuming that he must receive some type of help as well.

Q #2: Being from Lisbon and having made work in the US, how does your view of the United States translate from your Portuguese heritage? In the work In Image We Trust we get a reference to America with In God We Trust and you are saying that images can deceive, is this work to help understand America or to have Americans question themselves?
He also didn't go into the rest of this work but I did find the work interesting itself. He spent months putting different things on top of the turntable.
