I do not believe that an actin-based system for parallel computation could ever be more energy efficient than ceramic hardware.

It might give off less waste heat than your standard desktop PC; but that is not a valid comparison when you consider other, specialized types of circuitry.

Furthermore, the energetic cost of producing and purifying protein should be noted as expensive in the calculation of efficiency;

And the fact that actin filaments are not permanently stable in solution makes this system untenable.
