Is it possible to design a machine that has an efficiency that is greater than 100 percent?

An ordinary domestic heat pump appears to have an efficiency of up to 300% or so. That is it will deliver 3kw of heat for each 1kw of electricity it consumes.
But that is illusory because it extracts the extra heat from the water vapour in the air.
So in real life, the laws of physics win out.

Is a machine physically possible that has an efficiency greater than 100 percent?
Not if the laws of physics - specifically thermodynamics - are correct.
What is the mechanical efficiency of a machine whose work input is 100j and work output is 30j?
The mechanical efficiency of this machine is 30 percent.
Is 200 percent greater than 28 percent?
Yes, 200 percent is greater than 28 percent.
Why cant a machine be one hundred percent affective?
The reason why amachine cant be one hundred percent effective is as a result of losses.For Electrical machine such as alternator we have Mechanical losses(such as windage and frictional losses)and Electrical losses(such as copper loss in the rotor winding and stator winding).In Mechanical machine the main losses are windage and frictional losses.NOTE;ALL THIS LOSSES RESULT IN THE PRODUCTION OF HEAT,THUS REDUCING THE EFFICIENCY OF THE MACHINE.
Is it possible to have a percentage value greater than 100 percent?
yes like 200%,500% it can go over 100%

Can a machine's efficiency can be greater than 100 percent?
nope, efficiency o fa machine cannot be greater than 100%...theoretically it shows sometime that efficiency of a machine can be 100%, but practically it cannot be possible as there is some loss of energy is always involved in different ways.
Is it possible to design a machine that has an efficiency that is greater than 100 percent yes or no?
No. That would violate Conservation of Energy, so it follows that it isn't possible.
Can a machine be more than 100 percent efficient?
100% efficiency would mean that the machine is able to transform energy from one form into another without any loss of energy from the system in the process. For it to have greater than 100% efficiency, it would have to somehow generate additional energy, not contained in the system, in the process, and this is not possible.
What would a machine that had 100 percent mechanical efficiency be called?
an ideal machine
What machine on earth has the greatest percentage of efficiency?
Perhaps an electrical AC transformer can have 99 percent efficiency. A loudspeaker can have only 1 percent efficiency.
How does the output work compare to the input work for a machine that has an efficiency equal to 100 percent?
If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.
What is the mechanical efficiency of a machine whose work input is 100j and work output is 30j?
The mechanical efficiency of this machine is 30 percent.
What is mechanical efficiency in science?
mechanical efficiency is the percent of the energy that you put into a machine that was transferred to the load.
What is percent efficiency?
it is the amount of work that can be done. a machine can use 300,000 J of energy but it only uses 263,000 J. that is percent efficiency.
What of the machine compares the output work to the input work and is expressed as a percent?
That's the machine's "efficiency".
What is the efficiency of a machine that requires 100 joules of input energy to do 35 joules of useful work?
The machine efficiency is 35 percent (35/100).
