I don't think that we are likely to achieve the same efficiency as biological organisms with our machines (and I don't mean in terms of the wattage consumption of a silicon chip), our bodies do it better by consuming organic material thereby allowing us to operate - when machines can do this as well as run at speed, etc. then I will call them efficient.
