Like how the thermodynamics of gas is independent of microscopic details of what gas is, his derivation does not depend on a theory of what light is, such as
Maxwell's electromagnetism. In contrast, Maxwell predicted radiation pressure directly from his theory of electromagnetism. Therefore,

With one cycle, we have pumped energy away from the cold body. Since the energy has no where else to go, it must have ended up in the hot body. If light has no pressure, then this transport

Consider a perfectly reflexive piston with a mirror in the middle, and two black bodies connected to two heat baths at its two ends. One body is hot at temperature

Move the mirror towards the hot body. The hot body would be forced to absorb photons, while the cold body would be forced to emit more photons to fill the space.

Remove the first mirror, and wait for the radiation trapped between the two mirrors to reach equilibrium with the hot body.
