I think here there is a misunderstanding on the meaning of 'work'. It's most likely clear to all authors in this chain that if you take an LED and shine it onto an appropriate PV you will get voltage out of it. That much isn't governed by thermodynamic limits.

Likely the word 'work' here is in the context of collecting or generating energy in some manner. Your example here is essentially energy transfer. In analogy what you're describing is the transfer of power from driveshaft to axle, not what is happening in the engine itself.
