Water Ice sublimation gives much less isp due to the higher sublimation energy requirement and lower molecular weight.. > Frederick > Yet, to stick with the premise, if one had only dry ice to > exploit, then one might get much more energy per unit weight > exploiting the Bridgman effect, another beta-aether effect, > which is seen in many solid insulators under uniaxial > compression at high pressures.
