A flying toy spacecraft having one or more low pressure channels acting as the primary lift mechanism. The plasma constituent and red blood cells are removed from the separation device at least in part while whole blood is conveyed into the separation device. Swirl-producing elements are arranged upstream from the valve seat while a flattened face running perpendicular to the longitudinal axis of the valve is provided on the downstream end of the valve closing section downstream from the valve seat. A first end of the elastic member is disposed at the body. Using multiple update rates or magnitudes in the VGA control improves dynamic settling time. Besides individual peculiarity and importance, when integrated and associated they constitute the third-mode quantum generator that by zero point energy obtained through the interaction between light and material generates energy for any practical use.
