Here is a pic of the car in mid-2004. The Xof1 car is built from high tech fiberglass and low tech expanded polyurethane. Here the car's array has been taped with a medium tech two sided tape to which the photovoltaic cells will be 'stuck' to the car. This tape was very hard to come by since most of its production was being used in support of the second Gulf War. It was very sticky and provided about 1/16th inch of shock absorbing rubbery material.
