			== Relation to quantum effects ==

			Just as the Joule-Thomson effect (see [[cooling]]) this effect is
			predominantly not originating from quantum effects
			like e.g. quantum mechanical unfreezing of DOFs (which causes heat capacity jumps in muti-atomic gases).<br>
			{{todo\|questionable correctness - check in more detail}}

			== Relation to machine phase ==

			Giving crystolecules increasing space to frewheel on an axle or freereciprocate on a sliderail
			could exert ectropic forces on the motion limiters. Given the forces can be balanced out delicately.
			The effect to expect is likely to be much smaller than what one can observe in polymers though, since
			each relatively big crystolecule gets just one single thermal energy package according to the equipartitioning theorem.
			Thus each crystolecule acts just equivalently to one much smaller DOF in a polymer chain.

			The downside of the much more effective polymer chains is that they are
			* harder to mechanosynthesize due to their total lack of stiffness (not impossible: see [[molecule spanning method]])
			* more amenable to high energy radiation (including UV light) (just one break in a single bonded chain leads to failure)

			== Robust gases as alternative to delicate polymer chains ==

			Gas spring capsules (as used in [[Diamondoid heat pump system]]s) might be a solution solving both issues.
			There are no bonds to break in mono-atomic gasses.
			But this is basically just a pneumatic ultra high pressure (~1000atm - contacting gas atoms) energy storage.
			Energy density is lower than chemical and easy to calculate. {{wikitodo\|do that}}

			{{todo\|Explore if energy densities comparable to conventional chemical energy storage can be reached somehow.}}

			== Known potential for extreme safety ==

			Sidenote: Experiments (long before time of writing 2018) with state of the art metal hydride energy storage (in which strong entropic effects are present) have shown that very high energy density storages can be exceptionally safe. So safe that in case they are majorly abused (shot at, driven over with a tank) they just freeze instead of going off in a violent and dangerous explosion.

			=== The ideal energy storage ===

			One could imagine a combination of conventional energy storage and entropic energy storage such that
			the catastrophic event thwarting entropic part just slightly overcompensates the catastrophic event fostering conventional part
			and one gets the maximum possible energy density but still retains very high safety.

	In the nano-comos every degree of freedom absorbs a ~~quantum~~ of energy that is proportional to the environments temperature (this energy is E = 3/2kT; see [//en.wikipedia.org/wiki/Equipartition_theorem equipartition theorem]). When the alkanes are completely stretched they have only a few degrees of freedom (DOFs) and store less thermal energy than in a natural unconstrained state. When the alkanes are contracted and chaotically curled up they provide many DOFs and store a maximal amount of thermal energy.

	At non-zero temperatures the alkanes pull the handles together. So to draw energy from your battery you simply remove the handles from their locked positions and let them drive your workload. The emerging DOFs in the alkanes suck up the thermal energy of the environment effectively cooling the battery down. The reason behind this seemingly paradox behavior is that not the total energy but the [//en.wikipedia.org/wiki/Gibb%27s_Free_Energy Gibbs free energy] is subject to minimization. Some more information can be found here: "[//en.wikipedia.org/wiki/Rubber_elasticity rubber elasticity]" and here: "[//en.wikipedia.org/wiki/Entropic_force entropic force]"		At non-zero temperatures the alkanes pull the handles together.
