			With [[FAPP]] with certainty predictable lower limits for achievable power densities are 😲🤯🤪🚀 high.

			Unlike today at the macroscale with [[energy conversion]] based on [[macroscale style machinery at the nanoscale\|nanoscale machinery]] <br>
			there will be more alternatives beside electromechanical energy conversion with similarly high efficiency like e.g. <br>
			dedicated [[chemomechanical converter]]s that sidestep the fundamental Carnough efficiency limit by <br>
