Hi !
The perhaps easiest approximation to that in to use per volume elastic energy calculation.
You just need an E or Young module and a strain factor for that.
So, energy per m3 is
E per m^3 = 0,5 * E-module * relative strain^2
Using steel stats e-module is around 200000 MN/m2.
If extended/compressed by 10 %, that would result in 0,5*200000MN/m^2*0,1^2 = 1000 MJ/m^3.
So, this theoretical "stressed block" could release 1 MW for about 1000 seconds, before it needs to be re-stressed.
Nanotubes E-modules reach much higher values (factor 5 to 10(?) compared to steel), so energy densitiy increases considerablely.
Its a very rough sketch, but perhaps permits to get an impression about energy densities.

Mert
