earth emf, who cares it slowes down, it still be spinning in a mil. of years, oil will run out too, but it doesn't stop us from using it.
cosmic radiation, so what it's on the same level,(don,t see the point here) still present, still source of power, if we know how to tap it.
none of what you said is a proof of anything. sorry.
did you try to make a pm machine, numerous times and failed? i doubt it.
those ancient attemps to build it using gravity alone, is not what pm of second kind is.
nobody said you can make power out of nothing, taping perpetual power sources is the way to make pm machine of second kind.
tell me this, what happens when solenoid is deenergized?

1: As defined: Perpetual motion refers to a condition in which an object moves forever without being driven by an external source of energy
From the english wikipedia website:
A perpetual motion machine of the first kind produces strictly more energy than it uses, thus violating the law of conservation of energy. Over-unity devices, that is, devices with a thermodynamic efficiency greater than 1.0 (unity, or 100%), are perpetual motion machines of this kind.
A perpetual motion machine of the second kind is a machine which spontaneously converts thermal energy into mechanical work. This need not violate the law of conservation of energy, since the thermal energy may be equivalent to the work done; however it does violate the more subtle second law of thermodynamics (see also entropy). Note that such a machine is different from real heat engines (such as car engines), which always involve a transfer of heat from a hotter reservoir to a colder one, the latter being warmed up in the process. The signature of a perpetual motion machine of the second kind is that there is only one single heat reservoir involved, which is being spontaneously cooled without involving a transfer of heat to a cooler reservoir. This conversion of heat into useful work, without any side effect, is impossible by the second law of thermodynamics.The argument of the scientists is that no work can be done withou any external help. The perpetual motion also refers to violation of newtons I Law(Copyrighted by Pavan Kumar P N). According to perpetual motion, the direction of a body moving with a constant speed can be changed without the application of external force.
Or you can use the orginal word : which is roughly perpetual = eternal, without stop.
Point is : As soon as you use external energy to drive your machine its not a perpetual machine.
2. What is your 2nd point about a coil of wire: Maxwell isinīt vogue anymore too?
