You admitted your system requires fuel. Fuel is finite as I explained earlier when talking about the second law of Thermodynamics. That's why your machine is not a perpetual motion machine.
no fuel is just energy that in this case off sets or compensates for entropy or drag, resistance created by the machine.
For example
The sun is the fuel for a solar plant. this too is a closed loop power production system that could be consider perpetual motion as well, if for the fact the sun did not count as fuel or the energy source that powers the plant.
Like wise the hot earth interior becomes fuel for the closed loop steam/turbine system i purposed.
Argh! Make it stop!!!
The sun's fuel is finite. All fuel is finite. This is a consequence of the second law of Thermodynamics.
But you'd realise that this is also a consequence of the first law, the conservation of energy. Energy cannot be created nor destroyed, only converted.
Think about it, your geothermal power plant is supposed to give us energy to perform work right? Otherwise what's the point?
You're converting heat energy from under the Earth's surface to kinetic energy to drive a turbine to create electricity (another form of energy). This means that you are converting some of the Earth's store of heat energy into another form of energy that is not heat.
This means that there the Earth cools down faster.
Hence not perpetual.
