  We consider locally thermal states (for two qubits) with certain amount of
quantum entanglement present between them. Unlike previous protocols we show
how work can be extracted by performing local unitary operations on this state
by allowing those two qubits to interact with thermal baths of different
temperatures, thereby gradually removing the entanglement between them till
they reach a direct product state. Also we demonstrate that, further work can
be extracted from this direct product state by performing global unitary
operation, thereby establishing that work can be extracted from a system
composed of locally thermal subsystems even after removing quantum correlations
between them if the subsystems are thermalized at different temperatures. Also
we show that even if we consider a initial state where there is no entanglement
between the two qubits, we can also extract work locally using our method.
