First I apologize for my prolonged absence, I've been very busy.
But here is what I'm saying, in a steam engine operated induction generator for instance, heat energy is converted to mechanical energy used to move a copper coil through a magnetic field, the purpose of which is to make free(valence) electrons in the copper to cut magnetic flux lines in the field thereby generating flow of electrons(current) according to Faradays law of induction.
Now the mass of valence electron in a copper atom is 115837 times less than the mass of the whole copper atom. Mathematically, this means that 99.9991367% of thermo mechanical was wasted in generator just to move the electrons through the magnetic field.
So if it was possible to use the heat energy to move only the electrons without moving the whole atom, 115834.588 times more electric current would be generated.
