Radical Batteries
They consist of stored nano sized gas-tight sealed cells and a reactor. In the cells carbon (or silicon) atoms have each three bonds to one corresponding handle and a single bond to an opposing equal but mirrored part. The single bonds act as reversible predetermined breaking points. Some nano-mechanical mechanism outside the sealed cells (the reactor or chemo-mechanical converter) is able to grasp the handles of an incoming cell pull them apart and put them into a lock position. The result is an energy loaded cell with some pairs of high energetic C-radicals (C atoms with open broken bonds) inside. The breaking process evens out the nonlinearity of the single bonds by breaking / building many bonds at the same in a zip style fashion and also handling multiple cell at the same time too. The breaking process furthermore transforms the motion into a wider ranging movement with less force (lever effect / gearing up). This way single bonds are not jerkily ruptured which would waste energy as heat.

Unlike thermal engines with a radical-zip-battery one can directly convert from chemical to mechanical energy without the detour over thermal energy. Without this detour (which would immediately split up the yielded energy into recoverable free and irrecoverable bound energy) we are no longer bound by the maximum efficiency of an carnough-process and can get (within limits) arbitrarily near 100% reversibility. The key to this is the complete positional control over every reactant (aka machine phase chemistry) which enables us to prevent the released energy from going rampant and disperse in all available thermic degrees of freedom which are partly irrecoverable.
Expected features of radical batteries:
- recyclability: potentially excellent - depends on AP - system design
- durability: very high - like any AP product they slowly but unavoidably accumulate damage from natural high energy radiation - if one pushes the limits with power density spikes the battery components average lifetime will decrease exponentially
- measurability: excellent - one can count while zipping - there is zero self discharge
- power density: a lot higher than todays best motor-sport engines
- efficiency: very high - no thermal detour
- energy density: mediocre but sufficient - there's a lot of encapsulating structure per broken bond
- resource consumption: no scarce elements are needed
- health hazards: probably very low - no heavy metals are used
- danger (when crushed): probably flammable, unlikely explosive - the use of non burnable SiO2 & Al2O3 as structural material is preferable over diamond
Note that like in a hydrogen system a complete radical battery systems include both an energy storage and an energy converter (reactor). The generated driving motion can either be delivered to electrostatic motors / generators or in one or more steps merged to an axle of macroscopic scale. Its desirable to pack the functionally into different parts (e.g. different microcomponents). This allows adjustable storage to converter ratios.
