2 weeks i think continuously and was only stopped by man , is this perpetual motion
No. It uses power from the Sun, and if it did not receive power from the sun it would stop functioning. It is able to continue to operate at night or in heavy overcast conditions on banked power (batteries, or other), but only for a limited time (That might be one of the reasons it was operated in the desert). A true perpetual motion machine would be one which did not take energy from anything outside of itself. Such a thing is impossible.
