physics is so fucking weird and wonderful???
the paper is titled:
"Lossless Brownian Information Engine"
and the abstract begins:
"We report on a lossless information engine that converts nearly all available information from an error-free feedback protocol into mechanical work."

  Lossless Brownian Information Engine
  
  from Physical Review Letters
  
  We report on a lossless information engine that converts nearly all available information from an error-free feedback protocol into mechanical work. Combining high-precision detection at a resolution of 1 nm with ultrafast feedback control, the engine is tuned to extract the maximum work from information on the position of a Brownian particle. We show that the work produced by the engine achieves a bound set by a generalized second law of thermodynamics, demonstrating for the first time the sharpness of this bound. We validate a generalized Jarzynski equality for error-free feedback-controlled information engines.
