Q: Does the air bearing heat exchanger only work in a horizontal orientation? Or are other angles possible?

    JK: As discussed in the white paper, a downward restoring force many times that of the gravitational force acting on the mass of the heat-sink-impeller is generated by attractive interaction of the permanent magnet rotor and the high magnetic permeability stator. For this reason the device can operate in any orientation and the air gap varies little as a function of orientation angle.
