Query: Efficiency of isothermal active matter engines: Strong driving beats
  weak driving   We study microscopic engines that use a single active particle as their
"working medium". Part of the energy required to drive the directed motion of
the particle can be recovered as work, even at constant temperature. A wide
class of synthetic active particles can be captured by schematically accounting
for the chemical degrees of freedom that power the directed motion without
having to resolve the exact microscopic mechanism. We derive analytical results
for the quasi-static thermodynamic efficiency, i.e., the fraction of available
chemical energy that can be recovered as mechanical work. While this efficiency
is vanishingly small for colloidal particles, it increases as the dissipation
is increased beyond the linear response regime and goes through a maximum at
large propulsion speeds. Our results demonstrate that driving beyond the linear
response regime has non-trivial consequences for the efficiency of active
engines.
