Safety Factors

Hemocoels have huge safety factors or loading tolerances. Hemo-coel safety factors are much larger than those for pump-tube systems. Hemocoels work when full or almost empty. Were we to incorporate loading tolerances into our models, we might learn what redundancies and fail-safe mechanisms we might use to prevent failure of our smallest devices. For example, small machines have many places in them where a point defect can cause the entire machine to fail (Ref: Drexler, 1992). As in the human circulation, an embolus in a coronary or cerebral artery can spell disaster. This default assumption, however, does not usually apply to machines built on the macro-scale, because tolerances are larger. Many macro-scale machines continue to work despite numerous point defects. Because even a large number of point blockages fail to stem flow through a hemocoel, macro-machine assumptions might aid in modeling a small system analogously, so that its ultimate design might tolerate a high density of point defects. What should be important for hemocoel models would be the configurations of its surfaces as well as their changing fluid interfaces.
