      Not possible I’m afraid! Making something that would supply an unlined amount of energy would be along the lines of a perpetual motion machine. These are physically not possible as their operation would violate the 1st and/or 2nd law of thermodynamics. These are:

      -the amount of energy in an system is conserved

      -the total entropy in a system will always increase.

      Entropy is pretty much a term for disorder – it is a tricky concept that many physicists (myself included) have struggled with.
