I remember when Dr Jabbour was appointed to start up KAUST's renewable energy department. He was given 3 floors, each the size of a football field to design, configure, outfit and supply. This was not just solar energy, but many types of renewables. Huge undertaking and responsibility. For perspective, each floor was more than an acre and the three floors together are twice as big as the building AMTRON is building for Qamronics.

"The field has a uniform width of 53 1/3 yards (160 feet). If you calculate the entire area of a football field, including the end zones, it works out to 57,600 square feet (360 x 160). One acre equals 43,560 square feet, so a football field is about 1.32 acres in size."
