What is the efficiency of a machine that miraculously converts all the input energy to useful output energy?

Such a machine would have an efficiency of 100% and, as the question suggests, it would be a miracle. No real machine is 100% efficient because there are always losses.

What kind of machine converts chemical energy to electrical energy to electrical energy?
A machine that converts one form of energy into another form is called a transducer.
What is the machine that converts mechanical energy or motion into electrical energy?
"generator"
What form of energy is in washing machine?
What is the efficiency of a motor that converts 100J of electric energy into 70j of useful energy?
70% efficient Take: Useful work out --------------------- X 100 = efficiency Work in
What kind of energy is created when an energy conversion is happening?
Energy conversion takes place when one form of energy is converted to another form. An example would a turbine, which converts heat energy to mechanical energy, or a generator which converts mechanical energy to electrical energy, or an electric motor which converts electrical energy to mechanical energy. In all conversion processes energy is lost (i.e. it is converted to heat at a low temperature). The useful power output of a machine is always less than the power input, by a ratio called the efficiency, usually expressed as a percentage. Typical efficiency for an electric motor is 95%, for a car engine 25%.

What is an efficiency ratio?
The efficiency ratio for a machine usually refers to the ratio of the useful energy available from a machine and the energy put into it.

Why is a high efficiency machine is more desirable than a low efficiency machine?
A high efficiency machine will produce more of what is it that you want with the same power as the low efficiency one. In other words, for a low efficiency machine do as much as a high efficiency one, you have to give it more power (energy).
What device converts mechanical energy to electrical energy to chemical energy?
the poo-poo machine.
