Re: Mach2 power consumption #Mach2GTO

Actually ALL of the power consumed eventually is released as heat. Since energy can't be created or destroyed. Energy and mass can be converted but not created or destroyed.

If your power supply is feeding 100.000 watts to your system, 100.000 watts of heat is ultimately radiated from that system, at different points. Some from the power supply, some from the wires, some from the motors, some from the electronics, some from lights, etc.

Energy is always a net sum game. Always flowing from a high side to a low side. Disregarding the comparatively-trivial amount of heat generated in the core of the earth by nuclear fission of heavy metals, the earth radiates exactly as much energy back into space as it receives from the sun (and that core fission.) If it did not, it would be a planetary disaster.

I guess you mean 5 to 20% of the consumption is generated by the PS as heat anyways, depending on the PS efficiency.
The remaining 80 to 95% is used by the consumer, ie the powered device including the power line, which will transform it into mechanical power, and a bit into heat as well.
